Mnestica
a memory system for notes, reading, and cards
Last verified:
What is Mnestica?
Mnestica is an AI-assisted memory system designed for source material like notes, articles, textbooks, and lecture documentation. Users paste in their source text, and Mnestica automatically converts it into spaced-repetition flashcards that are scheduled for review using SM-2-style algorithms. The system helps users move from raw source text to a working study loop without having to hand-author every single card.
Key features include source-to-card generation where users choose card type (Q&A or cloze) and quantity, SM-2 spaced repetition that adapts intervals based on Again/Hard/Good/Easy ratings, a Notes knowledge graph that links concepts and misconceptions, an Incremental reading inbox for queueing articles and promoting extracts to notes or cards, and a Memory Coach AI assistant that helps repair failing cards by splitting, rewriting, suspending, or retiring them. The platform also includes a progress dashboard showing daily/weekly reviews, accuracy, streaks, and memory milestones across all decks.
Mnestica is best for people who already have source material (textbooks, articles, lecture notes, documentation) and want to turn it into a review loop without manually creating every card. It differs from Anki (which is strongest for users who want to author and tune cards themselves) and Quizlet (which is card-first) by being organized around the source material, with AI handling authoring support rather than replacing the memory work entirely.

Frequently asked questions about Mnestica
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 for a public fixture workspace that shows source text, generated cards, queue ranking, and one deterministic repair. No signup, private data, or live AI generation is required for that demo.
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 adds 100 credits every month for $9.99/month. On the current launch path that covers up to 100 generated cards per renewal. Credits never expire, roll over between months, 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 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.
What card types can I generate?
You can choose between Q&A or cloze card types when generating cards. You also select how many cards you want, and Mnestica routes the request through the reviewed default AI workflow before handing the deck back for review.
What is the Memory Coach feature?
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. This helps you repair cards that keep failing instead of just grinding them again.
