KeJi

关于产品

KeJi is a small Chrome / Edge extension for students who learn from video. Take notes while a lecture plays — every note remembers the exact second you wrote it. Click the note later and the video jumps back to that second. Notes appear as paw prints on the progress bar. Snip on-screen text with Alt+Shift+S, use popup, floating or side-panel layouts, search and export notes as Markdown. Free, no account — everything stays in your browser.
