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.

One app, the whole learning loop

From the first slide to the final answer.

Real product actions, arranged in the order international students actually study.

01 · Read

Read lecture PDFs in two languages, side by side.

Scroll naturally while BBNotes keeps the translated passage beside the original. No copy-paste, no lost context.

Explore PDF translation
02 · Listen

Follow lectures with bilingual captions and transcripts.

See the lecturer’s words translated while you listen, then revisit the recording as a timestamped bilingual transcript.

03 · Ask

Circle anything and ask an AI tutor.

Ask about the page, your handwriting, or the whole document. Every question stays anchored where you asked it.

04 · Solve

Handwrite your answer and get feedback on every step.

BBNotes reads your working and nudges you when the reasoning goes off track — without replacing the thinking that matters.

Source and translation remain aligned while you scroll.

Why it feels different

Between a notebook and a tutor.

BBNotes does not add a chatbot beside your notes. It makes the page itself understand what you are learning.

AI is built in, not bolted on.

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

It teaches instead of spoon-feeding.

Socratic prompts help you build the chain of reasoning rather than skip straight to an answer.

Every question stays anchored.

Unlike a chat thread, your questions remain beside the passage or handwritten step that made you ask.

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.
