A source-first study desk
Study with summaries you can check against the source
Use a summary as a first pass, not as the final authority. Choose the source, create the format you need, and keep a page, section, or timestamp beside every important note. Then attempt recall before looking, correct errors from the original, and plan a later review.
Choose your source
Different inputs need different checks
Start with selectable text, preserve page references, and inspect layout-heavy details in the original.
Open the pdf workflowResearch paper
Separate question, method, sample, findings, and limitations instead of flattening the paper into one paragraph.
Open the research paper workflowSupported YouTube video
Check transcript availability first, then tie important notes back to timestamps and visible context.

Keep the source open and verify names, numbers, quotations, scope, and conclusions before relying on the notes.

A checked study loop
Five passes, one source of truth
- SourceDefine the pages, sections, or timestamps actually covered.
- Generated notesChoose an overview, Key Points, Q&A, or visual explanation.
- Retrieval attemptAnswer before looking when the goal is active study.
- Source feedbackCorrect names, claims, quantities, context, and omissions from the original.
- Later reviewSet a reminder outside the app; a saved result is not a spaced-review system.
Roediger and Karpicke’s experiments found a delayed-retention advantage for repeated testing over repeated study under their reported conditions. Karpicke and Blunt’s experiments found retrieval practice outperformed their concept-mapping comparison. Neither study tested Summarise Visually or generated Q&A. Source-based feedback in this loop is a correctness check, not a claimed learning effect.

Important limits
The source still does the proving
- Generated summaries can omit context or misstate details.
- The verified PDF branch requires extractable text; the YouTube route depends on an available transcript.
- Summarise Visually is not fact checking, peer review, citation validation, or academic advice. Use the AI summary accuracy checklist before relying on consequential details.
- The current app is not a verified spaced-repetition system and does not replace source-based feedback.
