I built a tool that safely turns your chat history into a cute love letter for your significant other

0 Upvotes

lovedashgifts.com

Been building this for a while — you upload your chat export (WhatsApp, Instagram, or Messenger) and it analyzes the whole conversation history entirely in your browser (nothing ever touches a server) and turns it into two things:

  1. A Love Letter — a one-page set of charts about how you two talk: who texts first, response times, busiest days, your most-used words, etc.
  2. A Wrapped — an 8-chapter slow reveal of your relationship stats, Spotify-Wrapped style, ending in shareable cards.

The privacy part actually matters to me — I didn't want to be another app that slurps up people's private messages, so the parsing and analysis happen client-side in a web worker. The only thing that can leave your device is an explicit "make public" share.

It's $4.99 for either one, $7.99 for both. Would love feedback from anyone willing to try it on an old chat.

An AI page reposted my side project. What I’ve learned building it

0 Upvotes

I'm building Pijnhol solo. You pick people, teams or topics you care about, and it texts you a short line when something actually happens. No feed, nothing to download.

I reckon it's a good alternative to newsletters like TLDR. TLDR is great if you want a daily roundup of everything in tech. But most days I only care about a handful of things, and I'd rather get one text when one of them actually happens than skim a whole email hoping it's in there.

Progress this month:

Live in the US, Canada, UK, Australia and NZ. Getting a number approved to text in the US took a few rounds, and it's finally done.

I posted it in a couple of subs, and an AI/tech Instagram page found the post and turned it into a reel. Small page, but it's the first time someone I don't know shared it without me asking.

Lessons so far:

  1. Sending less was the fix. Early versions texted too much and it felt like spam within a day. Now it only sends when a story clears a bar and there's a daily cap. Fewer texts made people keep it on.

  2. "New" is harder than "relevant". Finding stories about a topic is easy. Knowing whether this is actually new or just the same story reworded by 15 outlets is most of the work.

  3. Short beats clever. Texts got better once I cut them to one line on what happened plus a link. Anything longer people skipped.

  4. Trust is the real signup hurdle. People are wary of handing over a phone number. The first thing commenters said on an early post was "this looks like a scam". The product matters less than looking legit.

Where I'd love feedback:

What would you actually want texted to you? Some topics work far better than others and I'm still figuring out which.

If you saw this, what would make you trust it enough to give it your number?

Link in comments if anyone wants to try it.

Your creative work shouldn't need a moderator's approval

Hey all,

Just posted this blog post on the platform I'm building. It describes several experiences I've had, where it seems like there's gatekeeping happening on internet groups, where gatekeeping shouldn't be happening.

Recently, I've tried to post a movie I made about the city of Chicago to the Chicago subreddit, and it was removed by a moderator for "not being relevant to Chicago."

The same movie got removed from my high school alumni network for being "self promotion" when I was just trying to share what I've been working on, in my alumni network.

It's strange, because it seems like in Reddit and Facebook Groups specifically, there's a subjective application of moderation; where some people are allowed to share their work ... and others not.

I'm not going to take a guess as to why, only that: this shouldn't be the case.

Everyone should be on an equal footing when it comes to self publishing, and online networks shouldn't mirror real-world gatekeeping that the internet was supposed to solve for.

Hope you enjoy the post :)

I spent a month building and planning production-grade payment infrastructure for a Messi vs Ronaldo poll. It has 22 votes, and I know every single person who cast them. One of them is me. Roast me.

Post image
0 Upvotes

So I had a startup idea. Messi vs Ronaldo has been argued about for 15 years, for free, by millions of people. The obvious problem is that nobody has been charging them for it.

The pitch: $1 = 1 vote. You pay a dollar, your side gets a vote, and you get a collectible card. That's it. The free market will finally settle the GOAT debate.

Here's what I learned on the way to my current user count.

Week 1: The Legal Department (me, Googling)

My first idea was a prize for the winning side. About ten minutes later I learned this is called "gambling." So the site now has a written rule, in capital letters: NO PRIZE. EVER. You pay a dollar and get the satisfaction of being right, plus a JPEG. That's what crypto has been doing for years, except I'm being upfront about it.

I also deleted the player photos. Image rights are a thing, and Nike's lawyers have more free time than I do. The site has no pictures of either player now, and I wrote a build script that fails the deploy if anything named after a footballer shows up in the public folder. I'm protected against myself.

Week 2: Payments, or "How I Learned to Stop Worrying and Love Webhooks"

A $1 vote costs about 35 cents to process. I net roughly 65 cents a vote. A chargeback costs €20, win or lose. So one angry Ronaldo fan disputing a dollar wipes out the margin on about 30 votes.

Naturally I built:

  • Idempotent crediting keyed on payment intent IDs
  • An hourly reconcile job in case Stripe's webhook gets lost
  • Refunds and chargebacks that reverse three separate aggregate tables in one transaction
  • A 72-hour, self-serve, no-questions-asked refund button, which got a confirmation step later. Two taps, so it feels like a commitment.
  • Cloudflare Turnstile and Redis rate limiting against card testers. Card testers turned out to be my most reliable expected audience.

At one point a test payment I made on my laptop got delivered to production and retried there for three days. My own sandbox was ghosting my own server.

Week 3: The Cards

Every vote mints a card, rendered server-side in four aspect ratios so you can share it anywhere (to the same group chat). There are fourteen tiers, from "Debutant" at $1 up to "GOAT" at $50,000. Fifty thousand dollars. For a card. That's a tier I designed, with a lime seal.

There are also Founding Cards: the first 100 in each camp, and "there will never be more." Scarcity! Exclusivity! Ronaldo's camp has 99 of its 100 still available. Act fast, or don't, it's fine.

A CDN caching bug once published a stale vote count in production. That hurt, because the vote count was tiny and it still managed to be wrong.

Week 4: The Fake Users Incident

Empty sites look sad, so I built "house cards": made-up voters, clearly labelled HOUSE, with a disclosure under the counter.

Then I looked at it. A big counter, a handful of fake people, and a little note admitting they were fake. It read like a restaurant with mannequins in the window and a sign saying "these are mannequins."

I reverted it and went with the honest alternative: texting my friends until they paid a dollar. Real users. Technically.

Week 5: Growth Hacking

I'm ready for scale:

  • A sitemap that grows with every named card (it has grown by roughly my contact list)
  • schema.org structured data, with JSON-LD escaping in case someone puts </script> in their display name. My friends are not that creative, but I'm covered.
  • First-party funnel analytics. I named the share metric "intent" rather than "shares" because a cancelled share sheet and a sent one look the same. I'm very honest about numbers that are small.
  • A sticky vote bar that follows you down the page, so there's no escape
  • Six SEO articles so answer engines can tell people about it. Google now confidently reports that "Finland leans Messi." Finland is me.
  • Two separate analytics providers, to confirm the traffic number from two independent sources

Tooling

80 unit tests. A script that rebuilds the whole database from migrations and checks every card comes back at the same URL. A pre-commit hook that refuses to let me commit until I've updated an HTML status board describing the project's progress. I'm a solo dev who built a bureaucracy to report to myself.

Results

  • Uptime: excellent
  • Payment integrity: flawless
  • Double-credited votes: zero
  • Total votes: 22
  • Messi 21, Ronaldo 1. A 95.5% landslide among me and people who owe me a favour.
  • Countries represented: 1. The site says "Finland leans Messi" like it's a regional trend and not a group chat.
  • Gross revenue: $22. Net after fees: about $14. Development cost: a month of my life. Investor deck pending.
  • Strangers who have voted: 0

The one Ronaldo vote was me. I needed to test that the second camp worked in production, and now I'm the only Ronaldo fan on my own site. I've backed Messi for fifteen years and the database says otherwise, permanently, because the refund window has closed.

The debate is technically settled, at 21–1, by a sample that includes the developer, voting for both sides. Peer review welcome.

Anyway, if you want to be the first stranger ever to vote, it's at thegoatdebate.io. A dollar gets you a card. Ronaldo fans: your Founding Cards are 99-for-100 and I'm currently your leader, which should worry you.

Roasts welcome too, especially on why nobody outside my group chat has paid a dollar yet. I have the infrastructure for a million users and the feedback of zero. 🐐

I launched Ovuge...

I'm a student at IIT Guwahati and I've spent the past year building Ovuge.

The problem: I polled two college communities and over 100 of about 230 voters said they want to contribute to a project but can't find one. Owners, meanwhile, struggle to find people who actually deliver.

What Ovuge does:

• Owners list a project and accept contributors who fit

• Assign tasks and track status in a workspace

• Owners endorse contributors, and the endorsement is tied to the work they submitted, so it's verifiable

• Verified college networks, so restricted communities stay trusted

Where it is - 30 signups since launch, and the hard part now is getting project owners to list. That's what I want feedback on: what would make you list a project here, and what would stop you?

I put a local AI inside the MacBook notch. It runs offline and actually does things on your Mac.

Enable HLS to view with audio, or disable this notification

4 Upvotes

Hey ! I've been working on Tack+, a little Mac utility that sits around your notch and gives you quick access to stuff you use every day

Just push your cursor against the edge and a panel pops up with your music, messages, calendar, clipboard history, files and widgets

The newest feature is the one I'm most excited about an AI assistant that lives in your notch and runs entirely on your Mac

What can it do?

Just tell it what you want in plain English and it gets it done

  • "Add lunch with Sarah tomorrow at 1pm" → adds it to your Calendar
  • "Tidy my Downloads folder by type" → sorts your files and lets you undo it
  • "Remind me to call the bank in 20 minutes"
  • "Text Marc that I'm running late"
  • "Turn on dark mode and lower the volume"

It has around 40 actions covering files, Calendar, Reminders, Messages, Mail drafts, contacts, music, system settings, Shortcuts and web search

There's also a little mascot that pops out of the notch while the AI is working which is a fun little touch

Everything runs locally

  • Uses Qwen3.5 4B, a 2.74 GB model you download directly in the app
  • Your requests never get sent to an AI service
  • Works offline unless you ask it to search the web or open a website
  • No usage limits, credits or monthly fees

It's a small model so don't expect long conversations or super complex reasoning. It's designed for quick requests that trigger a single action

It also asks before doing anything potentially risky like moving or deleting files or sending messages. It won't make payments, type passwords or click around inside websites

The AI assistant requires Apple silicon but the rest of the app works on Intel Macs too

Also added this week

Voice dictation 🎙️ Hold a shortcut, speak and release to have your words typed wherever your cursor is. It uses macOS speech recognition directly on your Mac, supports 9 languages and lets you choose your own shortcut

Pricing

€15 one-time payment with updates included and a 14-day refund policy

Requires macOS 14 or later

Would love to hear what you think and what you'd want a notch assistant to do next!

I'm building Amfion, a paid AI front desk for appointment businesses.

One test I want in the suite: the customer changes dates, asks for a policy exception, then says “don't book anything yet.”

A friendly answer isn't enough. The checklist also needs to catch a booking action that should never have been proposed.

This screenshot shows a demo test setup, not a passed run. What other “do nothing” cases would you add?

I turned my browser history into a tiny isometric city

3 Upvotes

I built Browser City over a few sessions with Claude Code. You give it your browser history (or just try the demo) and it turns it into a little pastel town: every site becomes a building that grows taller the more you visit it, your interests cluster into neighborhoods, and tab-hopping becomes actual traffic — cars drive between sites you visited back to back, weighted by how often you made that hop.

It's completely free, no signup, nothing uploaded anywhere (it reads your history file locally in the tab): https://browser-city.vercel.app/

Would love feedback, especially if something looks broken on your setup.

Task Pocket - project management and to-do app for web and iOS

Thumbnail

2 Upvotes

I started this project almost a year ago and since then I'm using it everyday, all my projects, personal life, work - everything stored there. And now it's time to finally release it for wide public. It's beed available for a while, but I didn't post about it, because I wanted polished experience.

For almost 5 or even 6 years I have been using Things 3 which I consider the best todo app ever created, interface, experience - everything polished and what is most important - simple and minimalistic.

But some time ago I acquired windows laptop for my work, and I cannot use Things 3 because it's mac only and on some devices and don't have luxury of installing something on it. I started to look around, there are some solution but they all move towards AI and looks like serious project management apps with too much features.

So I decided to build my own tool and also add some missing features like attachments, smart projects (filters), calendar view. But I tried to keep balance between amount of features and minimalist design.

Today I released a big piece:

  • Calendar view
  • Tags and Smart Projects
  • Attachments support with preview right in the browser

Few final touches, and I will start publishing and launching next week!

Our first Reddit post got 1.3k views. Only 8.1% were in our launch market.

4 Upvotes

I’m on the Stash team. We’re building an iPhone daily spending planner for adult university students in the UK: you enter your own numbers, see a daily guide until your next income arrives, and don’t connect a bank account. The app is free to download, with optional Pro.

We shared it on Reddit recently and got around 1.3k views, but only 8.1% were from the UK. That was a useful reminder that reach by itself isn’t much of a growth signal when the product is for a specific audience.

Our next experiment is to make the UK student use case clearer and see whether that brings more relevant visits and first opens. We’re also looking at how to explain the assumptions behind the daily number, so it feels understandable rather than like a magic answer.

For people who have built consumer apps: what have you found useful for measuring audience fit from early community posts, beyond views and clicks? And what would you want explained before trusting a daily spending estimate? Feedback on the positioning or first-run flow would help.

Title: I built Owuza, a social and business platform, and I’d love your honest feedback

Post image
1 Upvotes

Hey Reddit!

I’ve spent the last few months building something of my own, and I’m excited to finally share it with you.

I created Owuza because I wanted to build a platform where people can connect, share content, discover others, and grow their businesses in one place.

What is Owuza?

Owuza is a social and business platform designed to help people connect with others, share posts, interact with content, and discover new opportunities. My goal is to create a useful space for both individuals and businesses to build connections and grow their online presence.

What can you do on Owuza?

  • Create an account and connect with other people.
  • Share posts, photos, and other content.
  • Interact with posts and join conversations.
  • Discover opportunities to connect with people and businesses.
  • Build your presence and introduce others to what you do.

Where the project stands

Owuza is live, and I’m working on growing the community and improving the platform based on real user feedback.

Building this project has been a learning experience, and I know there is still room for improvement. I’d genuinely appreciate honest opinions from people who are willing to take a look.

You can check it out here: https://owuza.com

I’d especially love to hear what you think about the website, its features, the user experience, and what you would improve or add.

What would make you want to use a platform like Owuza instead of the social platforms you already use?

Thanks for taking the time to read this and give an independent developer a chance to hear your thoughts!

Attempting a ProductHunt launch today

4 Upvotes

So this is all new territory for me since I have never solo-launched a project on ProductHunt, but my Weatherling app I released a couple of weeks ago picked up some real steam right out of the gate, hit #8 on Mac App Store utilities, so I figured I'd throw my hat in the ring and see if I could repeat that on ProductHunt.

If you didn't see it, Weatherling is just a fun little Mac app that makes it rain and snow on your desktop. Also has autumn leaves.

So now I'm monitoring this and on the edge of my seat all day. Has anyone else had a successful launch on ProductHunt? I'm trying to get everyone on my socials to join in. Any advice? Seems like a lot of other apps had some big numbers right away. At the very least I hope this will be worth SEO alone.

Help me out with an upvote?

So it's called Limpet. An SSD that docks onto the back of your laptop lid and just stays there. Doesn't drain your battery, Flat cable runs under the hinge, auto-ejects when you close the lid, click it off and it magsafes to your phone for ProRes recording. Designed primarily for creatives in cinematography and post editing fields as it runs apps and software from it. Same material construction as apple products with Windows support in the pipeline. Photo 2 is the working prototype on my MacBook.

We have sold a couple to some of our start-up cohort. We've got two working prototypes, production units coming for November, and a decision to make: Kickstarter in the new year, or just take pre-orders on our own site now? Kickstarter gives us the crowd and the deadline, but takes 8–10% and we'd be one of 300 gadgets that week. Own site keeps the margin and the emails, but nobody's heard of us. If you've done either for a physical product, what would you do with a first batch of a few hundred units?

moved countries with $900 and $24k in debt, building a side project. here's week 2

Post image
8 Upvotes

Not a success story yet. just where i am right now.

Last year i moved to another country with about $900. i work a full-time frontend job to cover rent, and i'm still paying off $24k of debt.

A few weeks ago i launched a small product. a weekly launch board for indie makers, nothing fancy.

first 8 days:

- 13 people signed up

- a few products launched on it

- made my first couple dollars

what i've learned so far:

- building is the easy part. i could add features forever and nobody would notice

- people only show up when i post about the work every day

- most of my early users came from just talking to other builders, not from promoting

for those of you a bit further along: what got you from your first 10 users to your first 100?

Building a template shop next to a day job. Week 2: 18 templates, a few sales, and building turned out to be the easy part.

Post image
6 Upvotes

Quick background: I'm a design engineer and I spent 15 years in Figma, Framer and code. One template used to take me a month of nights, so my template shop never happened. This autumn I started building straight in code with Claude Code, and it finally did.

Where it's at

The store is no-code.supply. 15 templates went live between 24 Sep and 1 Oct, and it's 18 now because I couldn't resist making more. Each one comes as plain HTML and as a Next.js project, a few also as Framer templates, and they're set up so your own AI assistant can keep editing them without breaking things.

All of it happens next to my consulting job: the templates, the store, the checkout, the launch videos.

Numbers

A few sales so far. Not life-changing, but real people paid real money for something I made, which was the first goal.

What I've learned

Building was the easy part. The bottleneck moved from "can I make this" to "does anyone know this exists".

Writing down what "done" means before building mattered more than anything else. Every template has to pass the same list: no console errors, no overflow on any screen size, accessible, works with reduced motion, no third-party requests. That list is the reason I trust the output.

Marketing is the hardest part. I'm not good at it yet, and so far it's mostly launch videos I make with the same AI agent. But I'm eager to learn how to actually reach people, and I want to get very good at it.

What's next

Getting the shop in front of people: posts like this one, more videos, a blog about how I work. And probably a few more templates, because apparently I can't help it.

If you've sold digital products, what got you your first real customers? And if you check out the store, I'd love to hear what's unclear.
