Does Revu make things up (hallucinate) when generating content?

Generation is source-grounded. Every generated card, guide, or question includes a citation back to the exact slide, paragraph, or timestamp it came from. You see the citation before accepting the card, so hallucinations are caught at the review step — not after they've entered your memory.

Can I regenerate cards I don't like?

Yes. Every artifact has a one-click 'regenerate' that keeps the source but rewrites the card from a different angle (new wording, new example, reversed cloze). Nothing is permanent until you approve it.

How does multi-source synthesis work?

Select multiple sources — say, five lectures plus your syllabus — and ask for a study guide. Course Studio finds overlapping concepts, de-duplicates, and writes a guide structured around the syllabus with citations pulled from across all sources.

Are generated flashcards editable?

Everything is editable, reorderable, and taggable. You can rewrite a card, flip front/back, adjust difficulty, or split one card into two — same interface as your hand-authored cards.

Is Course Studio included in the free plan?

Course Studio is a Revu Pro feature. The free plan supports hand-authored cards and the full study loop (FSRS, sessions, coverage). Pro adds the AI generation pipeline and unlimited uploads.

Bring a semester of material — it's all fair game.

Step 1 — Ingest

Drop in anything. Revu handles the rest.

Upload PDFs, Keynote exports, .docx, Markdown, lecture recordings, or photos of whiteboard work. Revu extracts structure (headings, figures, equations), runs OCR on scans, and transcribes audio — all before a single card is generated.

Every format
PDF, PPTX, DOCX, MD, images, audio/video.
Layout-aware extraction
Two-column layouts, footnotes, figure captions, equations — parsed correctly, not flattened.
OCR + transcription
Handwritten notes and lecture audio convert to text with timestamps you can jump back to.

Step 2 — Synthesize

One source set. Every study format.

Pick sources. Pick formats. Revu writes a study guide from 5 lectures simultaneously, a concept map that spans chapters, a quiz that mixes every topic, or flashcards for spaced repetition — all pulled from the same material with explicit citations.

Step 3 — Trust, then approve

You are the final editor. Every time.

Generated content doesn't enter your study system until you approve it. Review each card side-by-side with its source paragraph. Edit in place. Regenerate from a different angle. Reject and move on. No auto-dumping into your flow.

Source-cited cards
Hover any card to see the exact slide, paragraph, or timestamp.
One-click regenerate
Keep the source. Rewrite the angle, wording, or format.
Bulk edit
Reject 20 cards at once, tag, split, or merge across sets.

Under the hood

Built for real exam prep.

Course Studio isn't a prompt-in-a-wrapper. It's a layered pipeline that respects your sources, your structure, and your judgment.

Syllabus-aware structure

Revu extracts your syllabus into required sections so generated content mirrors the course's own structure — not a generic outline.

Citation-first

Every card, question, and paragraph links to its source slide or timestamp. No phantom facts, no unsupported claims.

Multi-source synthesis

Generate from 10 lectures simultaneously. Revu deduplicates, consolidates, and organizes — you get one clean artifact, not ten overlapping ones.

Regenerate, don't delete

Didn't love a card? One click rewrites it from a different angle — same source, new phrasing — instead of forcing you to hand-fix or start over.

Question-format calibration

Revu picks card formats appropriate to the content: cloze for definitions, MCQ for discrimination, Q/A for explanation, problems for application.

Version history

Every regeneration is saved. Compare previous generations, restore a version you liked, or diff two wordings side-by-side.

Frequently asked

Course Studio, answered.

PDFs, lecture slides (.pptx, Keynote exports), Word docs, Markdown, handwritten notes (photos or scans), and audio/video lecture recordings. Course Studio runs OCR on images and transcribes audio before processing.
