How it works
Three steps, then you publish.
transcription
Speech recognition aligns every word to the waveform, adds punctuation, and marks speaker turns as they happen.
Style, review, export
Start from a preset or fine-tune fonts and line breaks, then export SRT, ASS, VTT or a burned-in MP4.
Inside the studio
The details that decide whether captions feel native.
Timing you never have to fix by hand
Every word is anchored to the waveform, so a line lands on the syllable instead of drifting two seconds behind. Cue lengths stay inside readable limits even when someone talks fast.
Speaker turns
Two voices, one room? Each turn is labelled so interviews and panels stay readable.
Brand presets
Save font, colour and safe-area rules once, then apply them to every project in a click.
206 languages
Auto-detect the source, or translate into another 206 languages free.
Four exports
SRT and VTT for platforms, ASS for styled burns, TXT when you only need the words.
Who it is for
If you publish video, this is your last subtitle tool.
Different teams, same requirement: captions that survive review without a rewrite.
Creators
Ship every upload with readable captions instead of losing an evening to a subtitle editor.
Course teams
Lecture after lecture, keep terminology consistent and line length inside the safe area.
Localization
Export a clean SRT as the source file your translators actually want to work from.
Agencies
Turn around client videos overnight, with a look that matches their brand, not ours.
Questions
Frequently Asked
what files can be handle?
MP4, MOV, AVI, MKV, WEBM FLV and common audio formats like MP3, wav, aac, m4a, flac, ogg up to 2 hours.
Do I have to pay before I try?
No. A new account starts with 30 free minutes. Credits are consumed per minute of audio and stay valid for a year, so you are never locked into a subscription.
Is my video uploaded somewhere?
Only the extracted audio is sent for transcription. The video itself stays in the browser, and audio objects are released as soon as the job finishes.
Can I edit the captions afterwards?
Yes — the editor opens right after generation. Fix a word, merge two lines, or shift a cue, and the exports pick up the change immediately.
