The problem

Translation lag is a product bug, not a localization problem

Translation lag ships broken UX to 40% of your users when the English feature launches and everything else stays behind.

Translators re-touch strings the dev already changed: twice. Manual handoffs mean double work and out-of-sync locales.

Locale files diverge across branches. Staging passes, production breaks. And nobody catches it until a user reports it.

There's a better model.

How it works

Three steps to sync-first localization

1

Connect your repo

Authorize GitHub, GitLab, or Bitbucket in under two minutes. Tonguesage reads your string files: JSON, YAML, PO, XLIFF. No migration required.

2

Tonguesage detects changes

Every commit, Tonguesage extracts new or modified strings and computes a precise diff. Only what changed goes to your translators: not the full file.

3

Locales ship with the release

Translators see the diff view, approve, and the merged locale lands back in your branch before the sprint closes. Every language on the same release.

Features

What Tonguesage does for your team

Auto-detect string changes on push

Every commit triggers a diff extraction. New strings, changed strings, deleted strings: all flagged and routed within seconds of the push.

Branch-level locale isolation

Feature branches get their own locale context. Strings from your feature branch never bleed into main until the branch merges.

Translator diff view

Your translators see only the strings that changed: with context, the old value, and the source language side by side. No CSV exports.

Sync status dashboard

See exactly which strings are synced, pending, or stale across every language. One view for your entire localization state.

Early access

From teams who've used it

"We cut translator re-touch requests by more than half after switching. Our localization PM finally stopped being the sprint bottleneck."

Senior Engineering Lead Fintech, Tonguesage early-access program

"I used to export locale files manually every release. Now it just happens. The diff view alone is worth it."
