One pass through your work, end to end
Each step hands the next one a real version of the file, so nothing is re-uploaded and nothing is lost between tools.
Organise
Projects hold the files, languages and history of one piece of work.
Process
Convert, retime, clean, merge and bulk-edit on the server.
Translate
A Subtools-managed provider, or your own API key.
Quality check
Reading speed, overlaps, line length, empty cues.
Edit
Fix cues by hand where judgement beats a rule.
Version
Every result is a version you can compare and restore.
Export
Download the finished subtitle in the format you need.
Reuse
Save it as a preset or pipeline and run it again.
This is the actual product
Not a mock-up — these are screens from the running app.



Private by default
Your subtitles are reachable only through your own account. Nothing you upload is published, listed or shared.
Your keys stay yours
Connect your own translation provider and the key is encrypted at rest. No route ever returns it — not even to you.
The server does the work
Processing runs on our servers, not in your browser, so every client sees the same result and the same history.
