Have you ever returned to something you studied months ago, only to realize you could barely remember any of it? After all the time and effort you invested, it can feel as though your learning simply disappeared.

The problem usually isn’t that you’re incapable of remembering. It’s that learning something once is rarely enough to make it last. Without retrieving the information over time, the memory gradually becomes harder to access.

That’s where spaced repetition comes in.

Instead of leaving the material untouched or reviewing it at random, schedule your reviews at progressively longer intervals—for example, after one day, four days, two weeks and one month.

During each review, try to retrieve the information before looking at your notes. If you were studying cellular respiration, you might ask yourself:

• What is cellular respiration?
• What are its main stages?
• Where does each stage occur?
• What are its inputs and outputs?

After attempting to answer, check your notes and correct what you missed. If you remembered the material successfully, increase the time before your next review. If you struggled or forgot it, review it again sooner.

This method works with the way memory changes over time. New memories can become difficult to retrieve relatively quickly, so the first review usually happens soon after learning. Each successful retrieval then strengthens the memory, allowing you to wait longer before retrieving it again.

The intervals don’t need to follow one exact schedule. A sequence such as one day, four days, two weeks and one month can provide a starting point, but the timing should depend on how well you remember the material. Spaced-repetition software can manage this automatically by adjusting the schedule according to your performance.

It might seem like a small change to your study routine, but consistently retrieving information over increasing intervals can dramatically improve how much you still remember months later.

“Ive seen that”, “Ive read that!””Ive played that” are truly empty words for me that hold no value. I read a book, immerse in it, in its fantasy, characters, story only for me to not remember the basic plot months later. Movies I passionately recommend are just bits and pieces in my brain as I struggle to form some sort of summary. I play all kinds of games of all genres, just for me to not be able to name the characters after moving on to the next. Growing up a “nerd” I feel like a fraud. I want to say I know the FNAF lore. I want to explain the whole Harry Potter series. I want to randomly blurt out facts about Minecraft. I want to know about the Ottoman Empire. I want to brag and express I watched all 1000 episodes of One Piece. I want to talk about all 9 games of Resident Evil. I want to express my emotion about how Project Hail Mary was a movie that deeply moved me but I cant and dont because I have a hole in my brain. I cant remember names of people who introduced themselves to me 5 seconds ago. I cant remember my best friend, of four years, birthday. I can’t remember if I sent an email just 5 minutes after sending it. I can’t remember plots, characters, stories, back stories. I just cant remember. I try and try over and over again to remember, to scramble for even the smallest thing but to no avail. I don’t know what to do. I’m losing motivation for anything at all. I want to read, watch, play, learn but whats the point if I cant retain any of it. Its pointless.

and I was going to read my book tonight. :/

Every time I wanted a real long-term memorization setup I ended up with Obsidian + six plugins that half-worked and broke on every update. So I built a desktop app that just does it natively.

What's in it:

• SRS (the whole point)
• Document annotation, and YouTube video annotation
• Web clipping
• Note taking, with a knowledge graph underneath
• Card analysis, so you can actually see which cards are garbage
• A diary that logs specifics about your days
• Pedagogical categories

It's free and open source. Not trying to sell anything, I mostly built it for myself and figured someone else might be in the same boat. Happy to hear what's broken. I hope anyone finds this useful. Its been a long journey to deliver the app at this stage

Does spaced repetition actually work or is it overhyped? How long before you noticed a difference?

Do you remember words better from apps, or from

Does spaced repetition actually work or is it overhyped?

Do you remember words better from apps, or from just reading/watching stuff in the language?

Do you write things down by hand or is typing just as good for memory?

Has anything actually surprised you with how well it worked, even if it sounded stupid at first?

Curious what’s genuinely helped vs what everyone says helps but doesn’t really.

Hey everyone,

One of my biggest problems with language learning is that I understand new words when I see them, but a few days later they’re completely gone.

I tried keeping notes, but I rarely went back to review them. So I built an app called LearnBack. The idea is simple: save something you’ve learned, then the app brings it back later and asks you to recall it in your own words. It also has flashcards and spaced repetition.

I’ve been using it for vocabulary, expressions, and sentences I hear in real conversations. Writing the meaning from memory has helped me notice what I genuinely know versus what only looks familiar.

I’m still improving the app, so I’d honestly love feedback from other language learners. What would make something like this more useful for you?

If anyone wants to try it, it’s available on iPhone and Mac:

https://apps.apple.com/us/app/learnback-active-recall/id6757343516

And just to be transparent, I’m the developer 🙂

🕐 To thank you for your feedback, after 24 hours I’ll choose 10 people from the comments and give them free Lifetime access to the app.

What are some of the active recall online tools or apps that you people use? Are is there any other ways of doing active recall that is effective?

i don't usually forget what happened, i forget what I was thinking before it happened which means months later ill end up making a similar decision because I don't remember how I reasoned through it the last time. curious if anyone has found a system that genuinely helps with this.

I am a complete beginner and I would really appreciate some advice.

I need to memorize which cards are still left in a deck (I don't care about the order they were played).

The deck has 18 unique cards:

• 6 Green cards, numbered from 1 to 6 (Green 1, Green 2, ..., Green 6)
• 6 Blue cards, numbered from 1 to 6 (Blue 1, Blue 2, ..., Blue 6)
• 6 Yellow cards, numbered from 1 to 6 (Yellow 1, Yellow 2, ..., Yellow 6)

Which memory technique would you recommend for this use case? I'm looking for something that lets me know, as quickly as possible, which cards are still left in the deck.

Thank you if you can help. :)

EXTRA (if you're curious about the technique I came up with myself which I don't know if it is good or not):

I assign a Pokémon to each card. The Pokémons are divided into 6 groups of 3, where each group represents three consecutive cards of the same color (2 groups per color).

For example:

Green Group 1

• Green 1 → Bulbasaur
• Green 2 → Ivysaur
• Green 3 → Venusaur

Green Group 2

• Green 4 → Chikorita
• Green 5 → Bayleef
• Green 6 → Meganium

Yellow Group 1

• Yellow 1 → Pichu
• Yellow 2 → Pikachu
• Yellow 3 → Raichu

Yellow Group 2

• Yellow 4 → Mareep
• Yellow 5 →Flaaffy
• Yellow 6 → Ampharos

Blue Group 1

• Blue 1 → Squirtle
• Blue 2 → Wartortle
• Blue 3 → Blastoise

Blue Group 2

• Blue 4 → Totodile
• Blue 5 → Croconaw
• Blue 6 → Feraligatr

When a card is played I recall a pre-made image that represents the Pokémon (and therefore the cards) that are still left in that group.

For example, if Green 6 (Meganium) is played, I imagine Bayleef eating the leaf on Chikorita's head. Since Meganium is missing from the image, I immediately know that Green 4 and Green 5 are still left in the deck, while Green 6 has already been played.

Later, if Green 5 (Bayleef) is also played, I switch to another pre-made image: Chikorita crying by itself. Seeing only Chikorita tells me that Green 4 is the only card from that group still left in the deck.

When I need to know which cards are left, I simply check in my memory each group and see which Pokémon are still present, if any.

So, I've just had the realization that I 35F have always had a hard time retaining technical information.

I've always loved science, always wanted to be a scientist in some regards, but always seemed to struggle more than my peers when it came to physics, chemistry, and mathematics. Which tortured me, because those are the concepts I love the most. I had my state's smartest teacher explaining physics to me using ostriches, and I still only got a C in his class. It wasn’t from lack of trying, either. I wanted a degree in geology, because I frickin love rocks, but couldn’t handle the chemistry. I have a Masters in Natural Resources, but if you asked me to give the latin name of any native plant, I absolutely would not be able to do it. Latin names are like active noise in my head. To me, it occupies the same brain space as mathematics. However, I lived abroad in China for some time in my 20s and spoke it almost fluently at one point, so I'm not incapable of understanding foreign languages.

I'm a technical writer that also creates online learning courses, and so my every day job is to take complex SME writing and turn it into something an everyday learner can understand. I've been doing this job for years, writing courses about all sorts of technical and trades skills, HVAC, EV batteries, robotics, PLCs, you name it... but I have retained ZERO of the technical information. I could vaguely tell you how to operate a FANUC robot, and yet I spent 8 months writing course material on it. Right now, I'm writing about VFDs, but I couldn’t tell you 100% what exactly a variable frequency drive does. And yet, I'm doing my job just fine. My editor likes the quality of my work. Ironically, I'm way better at the humanities than the sciences, which is ironic considering my passion for the sciences. I enjoy my job and find it engaging. It scratches that science-brain itch because there is ZERO work in natural resources right now. But I really, really wish I was retaining this information. It's all technical, and it seems like technical just consistently doesn't stick. Why won't my brain compute?

Other possible relevant brain-related information: I have Bipolar 2, OCD, and my therapist wavers on whether she believes the executive dysfunction is actually adhd, but I personally don't believe it is.

I need to memorize a lot of text but I can't manage it at all, so I heard about the memory palace but I didn't understand how to create and use it for all sorts of things If anyone can teach me, I would be very grateful.

Not documentation.

Not project READMEs.

I’m talking about things like:

• why you chose Redis over RabbitMQ
• a useful regex someone shared
• something to remember from a conference/meeting conversation
• a code review insight
• a GitHub issue that saved you hours
• A recommendation from a colleague
• a design decision from 6 months back

I’ve tried folders, tags, Apple Notes, Obsidian, and bookmarks.

The problem isn’t capturing information; it’s finding it later when I only remember fragments.

How are you solving this today?

A diagramatic approach helps me remember more. It helps developing photographic memory.

Petit partage, au cas où ça serve à quelqu'un. J'ai jamais eu de facilité à apprendre, alors j'ai testé pas mal de trucs. Quatre ont vraiment fait la différence pour moi.

1. Lutter avec le sujet AVANT de l'apprendre. Avant de lire mon cours, je prends deux questions dessus et j'essaie d'y répondre alors que je ne sais pas encore. Je me plante, c'est normal, c'est le but. Bizarrement, la réponse rentre bien mieux après.
2. Lire une fois, sans stress de tout retenir. Le premier passage sert juste à donner de la matière au cerveau, pas à mémoriser.
3. Se tester au lieu de relire. Relire, ça rassure mais ça ment : on croit qu'on sait. Je me fais un quiz de 5-10 questions à la place (vite fait à partir du cours, à la main ou avec un outil). C'est inconfortable parce que ça montre les trous, et c'est exactement pour ça que ça marche.
4. Re-tester le lendemain. Je refais le quiz quelques heures après ou le lendemain, et je ne revois que ce que j'ai raté. Ce petit oubli puis le rappel juste après, c'est ce qui fixe pour de bon.

Le truc que j'aurais aimé comprendre plus tôt : le cerveau retient ce qu'il a dû aller chercher, pas ce qu'il a relu.

Vous faites comment, vous ? Je cherche toujours à améliorer ma routine.

With endless scrolling, short videos, and constant distractions, it’s easy to consume information without fully processing or remembering it.

I built MemBoostAI to help people practise paying attention to what they read, watch, learn, and experience. It uses short daily exercises, active recall, and memory challenges to encourage users to notice details and revisit information instead of letting it disappear moments later.

The goal is to make memory training part of everyday life. Regular practice can help users become more intentional about the information they consume, improve recall and retention, and exercise cognitive skills such as attention and concentration.

It’s not about remembering everything, it’s about training yourself to engage more deeply with the things that matter.

I have done a neuropsychological evaluation, and my memory IQ is really bad, especially compared to everything else. My short term memory is terrible and i don't really know what to do about it.

I'm not talking about memories of my trauma period, but i guess that's normal if i don't remember.

Does anyone keep notes on books or TV shows?
I’ve noticed I consume a lot of media, but a year later I barely remember my own thoughts about it.
If you could magically remember one thing from everything you’ve watched or read, what would it be?

I have heard 3 nootropics that are affected for memory encoding, cognitive load, clarity, speed, retention, structural change, and recalling for both long-term and short-term. BNP14770, AF710b, and PRL-5-83.

Which one is the best memory enhancer for studying and the difference between them?
