OneDrop - Free Video Caption Generator
by•
Free browser-based video captioning. The video file never leaves your device — only compressed audio is sent to a transcription provider and deleted right after. On-device processing is available as an opt-in. Export MP4, SRT, VTT or TXT.

OneDrop Video Captions is a free-to-start AI caption generator for creators who post short videos and don't want signups, watermarks or a heavy editor just to add subtitles.
Drop in your video and Whisper AI transcribes the speech in the cloud. Then:
- Edit any word or timing in a click-to-fix editor
- Choose a caption style built for TikTok, Instagram Reels and YouTube Shorts [CONFIRM style count]
- Export burned-in MP4 (9:16 or 16:9), SRT, VTT or plain TXT
Why people use it:
- No signup needed to start
- No watermark on any plan, including free
- Real subtitle files (SRT and VTT), not just burned-in video
- Your video file stays on your device. Only compressed audio is sent for transcription and it is deleted right after processing.
Free plan: 2 minutes of captions a day.
Paid plans (from $9/month) add monthly minutes, longer videos, more styles and an optional accuracy Boost for Pro and Studio.
Built by a solo maker. Feedback and feature requests welcome.
