Subtitle generator features

More than auto-captions. A subtitle workflow.

Generate, edit, style, and export — all in one place. No timing nudges, no per-language re-uploads, no watermarks.

Word-level accuracy

Captions sync to individual words, not whole sentences. Reads like the speaker is talking, not lagging.

5 viral caption presets

Karaoke, viral pop, classic, docu, creative. One click between them — change your mind anytime.

100+ languages

Generate subtitles in any language. Translate once into many. Caption a multilingual video in a single pass.

RTL and Arabic done right

Native right-to-left layout, correct line breaks, and Latin transliteration for Darija — defaults, not options.

.ass / .srt / .vtt export

Power-user formats included. Pro editors get the .ass file with all styling baked in.

Drag-and-drop positioning

Place captions exactly where you want them on screen. Different position per clip if you need it.
