The old study loop

Stop stitching five apps together.

Copy a passage, open a translator, paste it into a chatbot, then return to your notes. By then, the lecture has moved on.

PDF Translator Chatbot Notes

The BBNotes loop

Read, write, translate, and ask in one place.

Your PDF, handwriting, lecture audio, translation, and AI tutor share the same context — so your thinking never leaves the page.

One continuous study workspace Less app-switching. More understanding.

Choose the mode that fits the room, your device, and the way you study.

Why it feels different

Between a notebook and a tutor.

The AI tutor uses your course material, handwritten steps, and question to explain the problem beside the relevant content.

Ask with the page already in context.

The tutor can read the PDF, handwriting, translation, and page context you are already looking at.

Find your next step with a hint.

Choose guided mode to work through questions and hints, build your reasoning, and continue your own solution.

Every question stays anchored.

Questions and explanations stay beside the relevant passage or handwritten step, ready to revisit with the source.

The person behind BBNotes

Built by a student who needed it.

I am an international student. AI teaching modes genuinely helped me learn, but typing every formula and copying every passage into a chat box killed the habit. So I built BBNotes: you write, read, and listen normally, while the AI tutor works directly on the material in front of you. I did not want another tool that skips the thinking. I wanted one that helps you understand the problem and build the logic yourself.
