The study engine

Not a chatbot. A study engine.

Most AI tools answer a prompt and forget it. Bo turns your whole course into a connected, tracked map of what you need to know, and keeps it up to date as you study.

Built only from your own course.

01

Upload your whole course

Lectures, slide decks, readings, scanned notes, even a photo of the whiteboard. Drop them all into one course. Bo runs OCR on anything scanned, so handwriting and images come in too.

Bo reads and maps every page

Bo does not just store your files. It reads each page and pulls out the topics and the concepts inside them, noting the page each one is on and whether your course defines it, applies it, or assumes you know it.

The same idea across files becomes one node.

This is the part a flat chatbot can not do. When the same concept shows up in three lectures, sometimes under different names, Bo merges it into a single node linked to every file it came from. It uses a second pass to check it is really the same idea, not two that just sound alike.

Merged from 3 lectures. Linked to the topic Cellular respiration.

The result is one map of your whole course. Topics hold the concepts inside them, and every concept remembers which lecture and page it came from, so nothing is double-counted and nothing is lost.

It keeps score

It does not just make tools. It tracks what you know.

What to study next

Every answer updates your map.

Each quiz, exam, and flashcard you do updates a mastery score for every concept it touched. Scores fade over time, so what you struggled with recently rises to the top. Study with Bo, quiz yourself, scores update, what to study next sharpens. The loop tightens every session.

FAQ

Questions, answered.

Upload as many lectures, slide decks, and readings as your course needs. Bo maps them all into one connected graph, so asking across your whole course works the same as asking about a single file.

PDFs, slide decks, documents, plain text, and transcripts. Scanned notes and photos of a whiteboard or textbook page work too, since Bo runs OCR to read them.

Bo merges it. The same concept under different names across files collapses into one node, linked to every lecture and page it came from. A second checking pass makes sure it only merges ideas that are genuinely the same.

Every quiz, exam, and flashcard updates a mastery score for the concepts it touched. Those scores fade over time, so a concept you struggled with last week surfaces as something to revisit, and Bo can point you straight at it.

No. You upload, and Bo does the rest: it extracts the topics and concepts, links them across files, and tracks your progress automatically. There is nothing to file or label.

Upload your course. Then just ask.
