Localhero.ai

Localhero.ai automates i18n translations for product teams. Connect your GitHub repo, and new strings get translated automatically on every pull request, with glossary enforcement, brand voice awareness, and translation memory that improves over time. Non-technical team members can review and edit translations in a web UI without touching code.

It diffs the branch against the base branch and translates only the keys that are new or changed, rather than re-translating the whole catalog on every run. Works with JSON (React, Next.js, Vue, i18next, next-intl, react-intl, LinguiJS, vue-i18n), YAML (Rails), and gettext PO files (Django, Phoenix, Lingui).
