Translate YouTube subtitles and SRT batches into multiple languages without losing timing or terminology
Built for recurring creators and course publishers. Import SRTs, ZIP batches, or YouTube captions, translate into multiple languages, then export files or publish back to YouTube.
How PolySubs works
Three steps from source to translated output
Import subtitles
Upload SRT files, ZIP batches, or connect YouTube caption tracks.
Translate
Translate into every target language with timing preserved and glossary support.
Export or publish
Download translated files or publish captions back to YouTube.
Why PolySubs
Subtitle workflows, not generic AI promises
Built for subtitle workflows
Not a generic AI tool—designed specifically for SRT timing, ZIP batches, and YouTube publish-back.
Better for recurring publishing
Handle weekly releases, course catalogs, and team handoffs without starting from scratch.
More consistent terminology
Glossary support keeps names, brands, and channel phrasing steady across translations.
Less file juggling
Import, translate, and export from one place—no download, rename, re-upload loops.
Who it's for
Built for people who feel subtitle work turning into ops
Owner-operator creators
Move faster on weekly releases without handling every subtitle file one by one.
Course publishers
Handle larger batches of lesson subtitles while keeping repeated terms consistent.
Small content teams
Keep subtitle work in one workspace with history, collaboration, and shared settings.
Not for
Enterprise localization workflows
If you need enterprise-grade project management, vendor coordination, or complex approval chains, this isn't built for that.
One-off bargain translations
If you translate a single file once a year, a free tool or manual process may serve you better.
Credits map to real workloads
Predictable pricing based on translated minutes
Credits are calculated from subtitle duration and target languages. No token math, no surprises.
Creator is the natural starting point
The default fit for recurring subtitle production.
