Editsub editor with the video, the waveform, the bilingual cue list and Co-pilot

Inside the subtitle editor

Timing on the waveform

Drag a cue's edges on the waveform. The video follows every change.

Co-pilot reviews the file

It flags long lines, overlaps and typos, then fixes them in one click.

Translation side by side

Every cue keeps its source above its translation, in 100+ languages.

Reading speed on every cue

Each line shows its CPS. Green reads easily, red is too fast.

Try it: shorten line 004 and watch its badge turn green.

  • Under 17 CPS · easy to read
  • 17–20 CPS · getting fast
  • 21+ CPS · too fast
