Record a Tutorial or How-To

Capture your screen with voice narration to teach a process step by step.

无需登录

Record your whole screen, a single window, or a browser tab — with audio. Everything is captured and saved entirely in your browser; nothing is uploaded.

Tip: to record audio from a specific browser tab, choose the “Chrome Tab” / “Tab” option in the share dialog and tick “Share tab audio”. System audio capture works best on Chrome and Edge.

🎤

Turn on the microphone to narrate as you go — explaining each step out loud makes a tutorial far easier to follow.

🪟

Share a single window instead of the whole screen to keep notifications and other apps out of frame.

⏸️

Use pause/resume to skip waiting on slow steps, keeping the final video tight and watchable.

🔒

Recording stays in your browser — ideal for internal training on tools you can't upload to a third-party recorder.
