AutoSubs is a free, open-source app that turns speech into subtitles on your own computer. ROKLIM turns subtitles into animated word-by-word captions — and can make the subtitles too. They overlap in one step and work well together.
Facts about AutoSubs come from its own page, github.com/tmoroney/auto-subs, checked in September 2026.

What AutoSubs does well
- Free and open source, runs fully on your computer.
- A choice of speech models, many languages and speaker labels.
- Works on Windows, macOS and Linux, and also with Premiere Pro and After Effects.
Where ROKLIM is different
ROKLIM starts where subtitles end:
- Layout: every word becomes its own Text+ clip, grouped and sized to fit the part of the frame you choose, rows coloured for the next steps.
- Animation: Fusion macros by clip colour, by word or by hand.
- Sound and effects: sounds under words, effects at timeline markers.
- Later edits: Change Font and Resize re-flow a whole range and keep every word in place.
Use them together
- Make the subtitles with AutoSubs — or with ROKLIM's own Create subtitles.
- In ROKLIM Layout, pick the subtitle track or the SRT file, press RUN.
- Animate, add sounds and effects.
When AutoSubs alone is enough
- You only need plain or styled subtitles, not word-by-word animated captions.
- You are on a Mac or Linux.
- You need speaker labels.
