Subtitles, generated. Every word on the beat.
Caption Room's AI auto subtitle generator transcribes your clip in 99+ languages and times every single word — so the karaoke highlight hits exactly as it's spoken, in your language, not just English.
Free. Runs in Chrome, Edge, Brave or Arc. Nothing to install.
How it works
The editor listens in the tab
Caption Room extracts a compact audio track from your clip inside your browser — the video file itself never uploads.
The AI times every word
The audio is transcribed with per-word timestamps in 99+ languages, so the karaoke highlight lands exactly when each word is spoken.
You stay in control
The subtitles drop onto the timeline fully editable — fix a name, retime a word, switch the style, then export burned-in or as .srt.
Built for the 98 languages the other tools forgot
Most subtitle generators are built for English first and everything else is hit or miss. Caption Room treats your language as a first-class citizen: film in it, get word-perfect subtitles in it, and translate to another language when you want a second version of the clip. The subtitles land inside a real free video editor — not a one-shot converter — so you can keep cutting after they arrive. New to captions? Start with the step-by-step guide, or see what Pro costs.
Subtitle questions
Which languages can it subtitle?
99+ languages — film in Croatian, Spanish, Hindi, Japanese or almost any other language and the subtitles come back in it, word-timed. Pro can also translate the captions into another language.
Is the auto subtitle generator free?
The editor is free; AI auto-subtitles are a Pro feature ($12/mo billed annually, $20/mo monthly, or $99 lifetime). Free accounts can still type captions manually and export with no watermark.
Does my video get uploaded?
No. Only the small audio track is sent for transcription — the video stays on your device, and editing and export run entirely in your browser.
How accurate is it?
Accurate enough that most clips need no edits — and when one does, every word is editable on the timeline before export, so a wrong name never ships.
Can it find the best moments too?
Yes — AI Clips (Pro) reads the transcript, picks the strongest moments and batch-exports them as ready-to-post shorts.
