Caption any video, free forever
Upload a video, auto-transcribe its speech, fix the timing, then export an .srt file or burn styled captions into the video TikTok/Reels style. Kapwing and VEED watermark free exports and cap your minutes — here everything is unlimited and your video never uploads anywhere.
1. Upload your video
2. Transcribe
How auto-captions work: your browser's speech recognition listens through your microphone while the video plays — so play the video aloud (speakers on) in a quiet room. Best in Chrome or Edge. It's not perfect: accents, music and overlapping speech reduce accuracy, which is why every caption is editable below.

3. Add / edit captions
4. Export
Burn captions into video
First burn downloads a ~24MB video engine + font (cached afterwards). Encoding runs on your device — long videos take a few minutes. Output is MP4 with your original audio untouched.
Frequently asked questions
Is it really free and unlimited?
Yes — unlimited videos, unlimited caption minutes, no account, no watermark. Competitors like Kapwing (10 min/month) and VEED (~30 min/month) cap free auto-subtitling and watermark exports. Everything here runs in your browser.
How does auto-transcription work, exactly?
It uses your browser's built-in speech recognition, which listens through your microphone. Play the video aloud (speakers on) in a quiet room while it listens. This is a browser limitation — web pages can't read a video file's audio track directly for speech recognition.
Which browsers support auto-captions?
Chrome and Edge have the best support. Firefox and Safari have limited or no speech-recognition support — if auto-captions don't start, use the manual "add caption" form instead; it's always available.
How accurate is the transcription?
Good for clear speech in a quiet room; worse with accents, background music, or overlapping voices. Treat it as a fast first draft — every caption's text and timing is editable before you export or burn.
What's the difference between SRT export and burn-in?
An SRT/VTT file is a separate sidecar file players can toggle on/off. Burn-in permanently draws the styled captions onto the video frames — best for TikTok, Reels, and Shorts where you want captions always visible.
Do you upload or store my video?
No. Your video never leaves your device — transcription, editing, and burning all happen locally in your browser.
