High-yield notes generator for dense lectures
Recall Engine is an AI note-taking and high-yield notes generator that turns your lecture PDFs into structured notes and summaries, keeping only the testable points, each one traced back to the source page it came from.
No credit card required
Lectures bury the high-yield points in slides full of filler. Re-typing them into notes wastes hours, and most summaries either cut too much or keep everything. You need the signal without the noise.

Frequently asked questions
Can AI take notes and summarise my lectures?
Yes. Recall Engine is an AI note taker that turns your own lecture PDFs into high-yield notes and summaries, keeping only the points most likely to be tested and linking each one to its source page so you can verify it.
Can I make notes from a PDF?
Yes. Upload a lecture PDF, select the pages, and Recall Engine produces structured high-yield notes. Both text-based and scanned PDFs are supported.
How are high-yield notes different from flashcards?
Notes give you an organised overview to read and consolidate, while flashcards test recall one idea at a time. Many students make notes first, then generate flashcards from the same lecture.
Is it free?
You get 30 credits free on signup with no card required, and credits are only used after a successful generation.
How do I know the notes didn't cut something important or get a fact wrong?
Every point in the notes is tagged with the source page it came from, so you can jump back to the original slide and check it in seconds. Treat the output as a study aid built from your own lecture, not an authority, and verify anything that feels off before you commit it to memory. If you think the summary trimmed too much, re-run it on a narrower page range to keep more detail.
Does it work on scanned or handwritten lecture notes?
Scanned PDFs work, since the lecture is read visually rather than relying on a clean text layer. Clear handwriting can be picked up too, but messy or low-contrast handwriting is hit or miss, so for handwritten material it helps to check the notes against your pages using the source-page links.
Should I make my own notes, or just use a condensed bank like a ready-made summary?
Pre-made summaries are written for a generic syllabus, while these notes are condensed from the exact lecture your faculty set, so the emphasis matches what your exam is likely to ask. They are a fast first pass to read and consolidate, not a replacement for active recall, so many students generate the notes, then turn the same lecture into [SBAs](/tools/sba-question-generator) or flashcards to actually test themselves.
