Live captions that work like subtitles.

A caption strip that floats over slides, code, or video. Stable, in step with the speaker, easy to read for a full lecture.

Join the waitlist

Every word, in writing. The full session transcript builds here as the lecture runs, ready to export when it ends.

LecturerSo malloc reserves the block, and free hands it back.

RoomWhat happens if you never call free? Good question, so

Live two-speaker captioning: the strip floats over whatever you're working on. Dimmed words are still being spoken.

What Caption+ does differently

Stable

Nothing you have read changes or jumps. Captions you can trust your eyes with, for a full lecture.

Technical

Course vocabulary comes out right: malloc stays malloc, in the lectures where terms matter most.

Readable

A steady rhythm that keeps pace with the speaker, so you stay with the lecture instead of falling behind it.

"As a deaf student, I struggled daily with captions that couldn't keep up with lectures. I built Caption+ because I needed it to exist."
