Translation as a CLI and an API — no localization team, no enterprise TMS contract, no vendor lock-in. Files you own, a CLI you run, a hosted API you don’t have to babysit.
The two traditional paths both cost you quarters. There's a third.
Every vendor says “AI-powered translation quality.” We published the receipts: 4,900 translations of real UI strings from our June 2026 pipeline, scored by three AI judges from other model families, with the dataset and judge prompts open-sourced so you can re-judge our outputs with a model of your choosing.
Localization shouldn’t mean handing a third party permanent custody of your product’s copy. Your outputs are plain files in your own repo, and the GitHub Action and benchmark harness are open source. The hosted backend receives the strings you send for translation, with their context — and catalog data only if you turn on catalog sync.

Polyglot collapses a category of recurring work that otherwise never goes away.
Detection, translation memory, glossary enforcement, and CI gating are the product — not a system one of your engineers has to build and babysit.
No back-and-forth with an agency, no string export/import dance, no waiting days for a turnaround on a one-word change.
New untranslated strings get caught in CI like any other check, and every generated translation waits for human review before it ships.
Source strings are sent to the translation provider only to produce the translation and are not retained long-term; your translation outputs and source files live in your own repository. If you need tighter operational control, tell us what your requirements are.
Start with the CLI and open GitHub Action on any plan. Team adds managed checks, catalog sync, and verified translation PRs.
