Use tool ↗About Tolgee AI Translator
Tolgee is a localization platform for software teams that combines a translation management system with an AI translator. Its autonomous translation feature reads context automatically extracted from the running application, so translations account for surrounding UI rather than being generated from an isolated string, and results can still route to human reviewers before publishing. It supports multiple LLM providers including OpenAI, Anthropic, and Google Gemini, or a self-hosted model, integrates via a JavaScript SDK, Docker, npm, and GitHub, and ships an MCP server for use from Claude Code, Cursor, or Codex. Tolgee is open source and built by a company based in Brno, Czech Republic, founded in 2021 by Jan Cizmar.

Pros & cons of Tolgee AI Translator
Tolgee's pitch is translation quality that improves because the AI actually sees the surrounding app context instead of translating strings in isolation, with a human-review step still in the loop. It's aimed at engineering teams shipping a localized product, not casual one-off document translation.
Pros
- Automatic context extraction from the live app improves translation accuracy over isolated strings
- Works with multiple LLM providers or a self-hosted model, not locked to one vendor
- Free cloud tier (30,000 hosted words, 3 seats) includes machine and AI translation
- Paid plans have unlimited seats, so adding reviewers costs nothing
- Open source with a self-hosted deployment option
Cons
- Plans scale with hosted words, and every language version of a string counts, so the bill grows with each locale you add
- Requires SDK integration into the codebase rather than working on arbitrary text
- Self-hosting requires infrastructure the free cloud tier doesn't need
Best for
- Dev teams localizing an app who want AI translation plus human review in one workflow
- Teams that want to self-host or choose their own LLM provider
- Projects already using Claude Code, Cursor, or Codex that want translation reachable via MCP
Not for
- One-off translation of a single document or email
- Non-technical users without a codebase to integrate the SDK into
