Source-first memory system
Turn notes and reading into a working memory system
Paste in your notes or an article. Mnestica turns them into flashcards, schedules them for review with spaced repetition, and helps you repair the cards that keep failing — instead of just grinding them again.
The demo uses sample material — no account, no AI calls. Sign up when you want to run your own notes.See how it works

The brain's ability to reorganize itself by forming new neural connections throughout life.
Open /demo before you sign up
Fixture source text, deterministic cards, and one scripted repair let you inspect the memory loop without private data or live AI generation.
How it works
From source text to durable memory, in one loop
Three steps, grounded in the current product rather than launch promises.
1
Paste your source
Drop in notes, a chapter excerpt, or an article you want to remember — or save source text in the reading inbox first and generate cards from selected extracts.
2
Generate cards
Choose Q&A or cloze, select how many cards you want, and Mnestica routes the request through the reviewed default AI workflow before handing the deck back to you for review.
3
Review and repair
SM-2 spaced repetition schedules each card by its own interval. When a card keeps failing, you can open the Memory Coach to split, rewrite, or retire it.
Or skim the FAQ — quick answers to the practical questions.
Mnestica is the public launch name for the product. If you run into an older Memoria reference in archived material, it refers to the same project under its pre-launch internal name.
Built for source-first study
The memory loop comes first; generation, notes, and repair support it.
SM-2-style spaced repetition under the hood
Source-to-card generation
Turn pasted text, notes, or eligible reading extracts into a review-ready deck. You choose card type and quantity; Mnestica handles the reviewed default AI routing behind the scenes.
SM-2 spaced repetition
Each card's interval and ease factor adapt to your Again/Hard/Good/Easy ratings, so important cards come back before they fade.
Notes knowledge graph
Capture concepts, examples, and misconceptions as typed notes that link into a graph — and stay connected to your cards across decks.
Incremental reading inbox
Queue articles and pasted text, read them block by block, promote extracts to notes or cards, and postpone the rest without losing the thread.
Memory coach
When a card keeps tripping you up, the Refine card button in the study view opens an AI assistant that can split, rewrite, suspend, or retire it — always on demand, you stay in control.
Progress you can see
One dashboard for your daily and weekly reviews, accuracy, streaks, and memory milestones — across every deck and note collection.

Before you sign up
Questions worth answering up front
Straight answers — no marketing fluff.
What is Mnestica?
Mnestica is an AI-assisted memory system for source material. Paste in notes or an article, and it turns them into spaced-repetition flashcards scheduled for review, so you can move from source text to a working study loop without hand-authoring every card.
Can I try it before I sign up?
Yes. Open /demo and paste your own notes — no signup needed. Your pasted text is sent to an AI model to generate a small card set and is not stored. Prefer not to paste anything? A fixture walkthrough with pre-made examples is one click away on the same page.
How does the workflow compare with Anki or Quizlet?
All three use spaced repetition. The difference is workflow: Anki is strongest if you want to author and tune cards yourself, Quizlet is card-first, and Mnestica is organised around the source — your notes, reading, decks, and review queue live in one hosted loop, with AI doing authoring support rather than replacing the memory work.
How do credits work?
You start with 10 free starter credits, no card required. Mnestica Pro is monthly at $9.99/month with 100 credits each month, or annual at $79/year with 1,200 credits granted upfront each year. On the current launch path that covers up to 100 generated cards per monthly renewal or 1,200 per annual renewal. Credits never expire, roll over between billing periods, and stay with you if you cancel. Failed or zero-card jobs are refunded automatically.
Is my content used to train AI models?
Not by us. Mnestica is a hosted web app. When you request generation, the text you submit goes through Mnestica's hosted AI workflow and may be processed by OpenAI or Anthropic. OpenAI and Anthropic say API or commercial inputs and outputs are not used to train their public models by default, but provider abuse, safety, legal, and operational retention policies still apply. Do not paste material you are not comfortable processing through that workflow.
Can I export the cards it generates?
Yes. From the Decks page you can export a deck's AI-generated cards as Anki .apkg, TSV, or CSV. Self-serve export is deck-scoped TSV or CSV for AI-generated cards only. It is not full account export or a complete source-material export.
Can I cancel anytime?
Yes. Cancel self-serve from the Billing page; it takes effect at the end of your current period, and you keep paid access plus any remaining credits until then.
Who is Mnestica best for?
People who already have source material — textbooks, articles, lecture notes, documentation — and want to turn it into a review loop without hand-authoring every card. Less ideal today if you need offline sync or complex custom card templates.
Or email support — a human reads every message.
