From speech to SRT.In about a minute.
Broadcast-grade subtitle files — SRT, VTT, or burned-in — with reading-speed limits, line-length rules, and speaker labels handled before you ever open the file.
Subtitles that pass review
Platforms and broadcasters reject subtitle files for the same boring reasons: cues too fast to read, lines too long, splits mid-phrase. The generator enforces the standards up front so the file you download is the file that ships.
- 17 characters-per-second reading speed by default, adjustable
- Two lines maximum, 42 characters per line
- Cues split at sentence and phrase boundaries, never mid-word
- SRT, VTT, and plain-text transcript export
Names spelled right, every time
Custom vocabulary is shared with AI Captions: teach it a host's name, a product, or an acronym once and every future file gets it right. Speaker labels make interview and panel footage readable without guesswork.
- Custom vocabulary for people, brands, and jargon
- Speaker-labelled cues for interviews and panels
- Automatic punctuation, casing, and number formatting
- Find-and-replace across every cue in the file
Burned-in or sidecar — your call
Ship a sidecar file to YouTube for SEO and accessibility, or burn the subtitles into the pixels for platforms that strip metadata. Either way it is one transcript, one source of truth, and one click per language.
- Burned-in render or sidecar file from the same transcript
- Translate cues into 48+ languages before export
- Re-time an entire region by dragging once
- Works with footage from any camera or screen recorder
