How to add subtitles to a video

Most viewers watch short videos muted, and subtitles make long videos accessible and searchable. This workflow takes you from raw recording to publish-ready captions.

Add subtitles

In short

AI creates a timed first draft from the speech in your recording.
Review warnings for crowded captions, fast reading speed and overlaps.
Style captions and preview them on your own video.
Export SRT, VTT, ASS, SSA, SBV, SMI, TXT, JSON or a captioned video — no watermark.

Step by step

Upload your recording — one you own or have permission to use.
Generate subtitles after signing in; the credit quote appears first.
Fix the flagged lines: crowded captions, fast reading speeds, overlaps and lower-confidence segments.
Style and position captions inside the safe area.
Export a subtitle file or a captioned video.

Which export to choose

SRT — broad compatibility with video platforms.
VTT — web players.
ASS or SSA — styled workflows in editors.
Captioned video — styles burned into the picture, rendered in your browser.

Frequently asked questions

Can I edit without an account?

Yes. The sample, importing subtitle files, editing, styles and file exports work without signing up; AI generation needs sign-in and credits.

Do SRT files keep my styling?

No. Plain SRT and VTT do not preserve visual style; use ASS/SSA or export a captioned video.
