About Plainrec – Screen Recorder, No Limits
Record your screen as often as you like. Plainrec is a screen recorder with no video limit, no watermark and no account. Your recordings stay on your computer.
RECORD
- Record a tab, a window or your entire screen
- Add your microphone and your computer's sound
- Show your face in a floating camera bubble
- Pause and resume, with an optional 3-second countdown
- Save as MP4 in 720p, 1080p or 1440p
- See which sound is being captured while you record
EDIT
- Trim the start and end without recording again. The original is kept.
- Trimming happens in your browser. Nothing is uploaded.
CAPTIONS AND SUMMARY (OPTIONAL)
- Get captions, clickable chapters and a short summary from Google Gemini
- Download captions as .srt and the transcript as .txt
- Uses your own free Gemini API key. Only the audio of that recording is sent, directly to Google.
NEVER LOSE A TAKE
- Your video is written to disk while you record
- If the tab crashes, the recording is recovered next time
- All recordings wait in "Your recordings" until you download or delete them
PRIVATE BY DESIGN
- No sign-up, no cloud, no analytics, no ads
- Recordings are kept in Chrome's storage on your computer
- Open Plainrec from the toolbar or press Alt+Shift+R
Tip: Chrome can't capture sound from a single window. To include computer sound, share a tab or your entire screen and keep "Share audio" on.
