Everything between your source strings and a shipped translation

One editor for the team, AI that follows your glossary, and tools that plug into your build.

Editor

Translation editor
A convenient editor for strings with interpolation and HTML markup.
Translation history
Don't worry about translations that change: you can always see previous versions and restore them.
Real-time progress
Track project translation progress in real time.
Automatic quality checks
Placeholder mismatches, lost HTML tags and empty translations are flagged as “Needs review”.

AI translation

Claude and OpenAI
Language models translate whole phrases, keeping placeholders and HTML markup unchanged.
Your own provider key (BYOK)
Connect your own Claude, OpenAI or DeepL key and translate for free: no characters are taken from your balance.
Model choice
The model list comes straight from the provider's API. Pick the one that fits your project on price and quality.
Project glossary
Lock in the translation of key terms. The model must use exactly those, not its own wording.
Project style guide
Set the tone, the level of formality and length limits. They go into every request to the model.
Machine translation
Save time with automatic translation from Google, Microsoft and other machine translation providers.

Collaboration

Work as a team
Give your team access to the project and work on translations together.
Monitor usage
Plan usage statistics show how many keys each project takes.
Low prices
Affordable plans, and a custom plan if none of them fits.
Command-line tool
Push, translate and pull files from scripts and CI with npx and a localizify.json config.
REST API v1
Manage projects, terms and translations, trigger AI translation and pull localization files straight into your build.
MCP server
Connect Claude Code, Cursor, Claude.ai or ChatGPT and let the assistant manage your strings.
