Upload a PDF, photo or lecture slide. Quanta creates document-bound cards with three Bloom levels selectable from Essential, transparent source status and LaTeX formulas. Recognition quality depends on layout, images and handwriting.
European AI provider (Mistral, Paris) · document-bound · three Bloom levels selectable from Essential
Starter is free · one AI run included
„The biggest advantage […] is that the AI creates each card using reputable sources and also displays links to those sources, so you can read them yourself."No black-box promise. Every step is anchored in the code. PDF, JPG, PNG and WebP files up to 10 MB are supported.
A PDF, photo (JPG/PNG/WebP) or screenshot of notes or a lecture slide. Legible handwriting can be recognised.
The European AI provider (Mistral, Paris) analyses text and image at the same time and can capture formulas, diagram labels and structure formulas. The file path runs via the provider's standard endpoint, for which it gives no specific processing location.
With no selection, the card prompt prescribes per level counts, all three present and the emphasis in the middle. When you select one of the three levels across Bloom 1 to 6 from Essential, the cards must follow the form of that level.
The system instruction tells the model to use only information from the uploaded file. When PDF text can be extracted, the server checks verbatim evidence; a missing match does not discard a card in the visual scan path but leaves it without a verified seal.
A limited set of existing cards from your topic is passed to the model as avoidance context. This reduces identical or very close repetitions but is not a complete semantic duplicate guarantee.
New cards are saved directly in Quanta's study system. After your first rating, FSRS-6 calculates stability, difficulty and the next review date.
With lecture slides, diagrams and clipped text also affect what you can check. Our guide Flashcards from lecture slides shows how to check each answer against three complete slides.

Active recall
Karpicke & Roediger 2008 (Science 319:966) studied retrieval practice. That supports the methodological context but does not guarantee a particular outcome with Quanta.
Three Bloom levels
With no selection, Quanta prescribes per level counts, all three present and the emphasis in the middle. A selected level goes into the scan prompt with counts. Anderson & Krathwohl 2001 provide the taxonomy, not evidence of product effectiveness.
Document-bound
The prompt forbids additions from free model knowledge. Verbatim matches mark grounded cards when text is extractable; unmatched visual-scan cards remain without a verified seal.
With no selection, Quanta puts per level counts into the scan prompt, all three present and the emphasis in the middle. When you select one or more of the three levels across Bloom 1 to 6 from Essential, exactly that level goes into the scan prompt with counts, and Quanta checks the result against its form. This supports foundations as well as deliberate application, analysis, evaluation or creation.

Hallucinations are a risk with AI-generated study cards, especially for formulas and mechanisms. Quanta's system instruction restricts generation to the uploaded document. Server-side quote matching verifies evidence where text can be extracted reliably. In the visual file path, unmatched cards are retained because layout, formulas or OCR can diverge, but they are not marked as verified.

Complete profile details for school type, year and region or degree programme and semester can enrich the scan prompt. When they are missing, generation follows the level and terminology of the uploaded document without assuming an education stage.

Quanta renders inline LaTeX formulas ($f(x)$) and block formulas ($$E = mc^2$$) directly via KaTeX. The scan prompt instructs the model to output mathematical expressions in LaTeX. Paivio (1971) provides the theoretical context for visual and textual representations; it does not imply an automatic learning outcome.

What really sits behind the PDF scan
“The scan prompt is designed to create learnable concepts from the uploaded document instead of merely rephrasing exercises. Reading the file is handled by Mistral AI SAS, based in Paris, via the provider's standard endpoint, for which it gives no specific processing location; the basis is the standard contractual clauses. The provider contractually excludes training on the content we transmit. The 30 rolling days the provider states are its general figure for inputs and outputs (as of 27 July 2026); for the file interface it has, to our knowledge (as of 18 August 2026), not published a separate automatic deletion period, so here our own deletion carries the commitment: we delete the uploaded file copy immediately after processing, including when something fails. What gets analysed is the visual file content, including text, formulas and labels. With no Bloom selection, Quanta puts per level counts into the scan prompt, all three present and the emphasis in the middle; a level selected from Essential across Bloom 1 to 6 goes into the scan as a target with counts. Where PDF text can be extracted, quote matching checks the evidence. A match can fail because of layout, formulas, images or handwriting; the card then remains document-bound but does not receive a verified seal.”
