Frequently Asked Questions

Mnestica is an AI-assisted memory system for source material. You paste text — notes, an article, study material — and Mnestica turns it into spaced-repetition flashcards that it then schedules for review, so you can move from source material to a working study loop without hand-authoring every card.

Three things make it different from a plain flashcard app: AI generation (so you spend less time authoring cards), a lightweight notes + reading workspace that feeds the same review queue, and a “Memory Coach” that helps you fix cards that are not sticking.

All three use spaced repetition, so the underlying scheduling idea is familiar. The differences are about workflow, not theory:

• Authoring overhead. Anki is strongest when you want to write and tune cards yourself; Mnestica asks you to paste source text and generates cards from it. You still review and curate them.
• Scope. Quizlet is card-first. Mnestica is organised around the source — notes, reading extracts, and decks live in one workspace and feed a single review queue.
• Hosted & AI-native. Mnestica is a hosted service with AI generation built in, not a local-first app with plugins or offline sync.

Anki is powerful and free, with an ecosystem nothing else matches. Mnestica is not trying to replace every Anki workflow; it is a different bet for people who want source material, notes, reading, and review in one place, with AI helping on authoring instead of replacing the memory work.

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.

Public-facing launch copy, support replies, and current product pages should use Mnestica. If you spot a stale public reference, send it to support@mnestica.ai and we will clean it up.

Mnestica is best for people who already have source material (textbooks, articles, lecture notes, documentation) and who want to turn that material into a review loop without hand-authoring every card. In practice that tends to be:

• Students and self-learners working through books, lecture notes, or online courses.
• Professionals working through dense technical material where recall matters.
• Anyone who has tried Anki, agrees with the idea, and got stopped by the authoring workload.

It is a less good fit if you need offline sync, highly custom card templates, or media-rich cards today — those are not part of the current product.

The core pieces are in production today: the scheduler is SM-2-derived, billing runs on Stripe, and requested generation runs on hosted OpenAI and Anthropic provider paths with automatic credit reversal if a job fails or returns zero cards. Your content stays yours and you can cancel self-serve at any time.

That said, Mnestica is early. The feature set is deliberately narrow compared with ten-year-old tools. If you try it and something is missing, tell us — we read every message.

Yes. Open /demo for a public fixture workspace that shows source text, generated cards, queue ranking, and one deterministic repair.

The demo does not require signup, private data, or live AI generation. If the workflow looks right, then sign up to use your own material with 10 starter credits.

If the workflow looks right in /demo, signing up takes about 30 seconds. After that:

1. You land on your dashboard with 10 free starter credits, no card required.
2. You open Create, paste in the text you want to learn from, pick a card type and a number of cards, and submit. Mnestica chooses the reviewed default model under the hood.
3. Generation runs in the background. When it finishes you have a deck of cards you can review immediately.
4. The first time you review cards, the spaced-repetition scheduler starts; afterwards the Study page shows you only what is due that day.

If you want to go deeper before signing up, the Articles page walks through the method.

Credits are how we meter AI generation.

• Free plan: 10 one-time starter credits when you sign up. Enough to try real decks before deciding anything.
• Mnestica Pro: $9.99/month, with 100 additional credits added on each renewal.
• Credits never expire and roll over between months. If you cancel, you keep any remaining credits for as long as your account exists.
• A generation job consumes credits based on the card type and number of cards requested. You see the exact cost before you confirm the job.

On the current launch path, one credit maps to one generated card, so 100 monthly credits covers up to 100 generated cards per renewal at current pricing.

If generation fails or returns zero usable cards, the charged credits are reversed automatically. You do not pay for broken output, and if the reversal ever looks wrong you can email support with the job ID and we will reconcile it.

Today, Mnestica accepts:

• Pasted text in the Create flow — your notes, a chapter excerpt, an article body, documentation, etc.
• Selected extracts in the Reading inbox — passages you save while reading and want to turn into cards once you have worked through them.
• Your typed notes — notes you write in Mnestica can be linked to cards and used as supporting context.

Direct file upload (PDF, DOCX) and URL fetching are not part of the product today. The simplest workflow is still: select, copy, paste.

Do not paste material you are not comfortable processing through that hosted AI workflow. There is no local-only, offline, or no-provider generation mode today.

Two card formats are supported today:

• Question & answer (Q&A) — a question on the front, your answer on the back. The default.
• Cloze deletion — a sentence with a key term hidden, so you recall it in context.

You choose the card type and the number of cards before each generation. Mnestica keeps model selection behind the scenes on the reviewed default path.

Today, card editing happens through the Memory Coach rather than a plain text-editor. When you are reviewing a card, the Refine card button opens the Coach, which can:

• Rewrite a card whose prompt or answer is confusing.
• Split an overloaded card into smaller, atomic ones.
• Suspend a card temporarily so it stops appearing in reviews.
• Retire a card you no longer want to study.

Free-form inline text editing is on the roadmap and not in the product yet — we are being honest about it rather than hiding it. For now, the Coach flow covers most of the reasons people want to edit a card.

The Memory Coach is the part of Mnestica that uses a card's prompt, context, and review observations to suggest improvements. In the study view, the Refine card button opens it on the card in front of you.

It is on-demand, not something that changes your cards in the background. You see the suggestion, you decide whether to apply it, and the change is recorded so you can trace what was done and why.

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.

Yes. After signing in, open the Billing page, click Manage subscription, and cancel from the Stripe-hosted portal. Cancellation takes effect at the end of your current billing period; you keep paid access until then, and you keep any unused credits. See the Cancellation & Refund policy for the full details.

You can export the AI-generated cards in a deck from the Decks page as TSV or CSV for Anki or your own tools. 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.

You can also delete individual notes from within the product today. For a broader export, a corrected export file, or account deletion, For broader export, corrected export files, or account deletion, email support@mnestica.ai from the address on your account. We respond within one business day and act within the timelines described in our Privacy Policy.

Self-serve account-level export and deletion UI are still on the roadmap. We believe in showing what is and is not built, so you know what you are signing up for.
