AI localization with native Git sync for fast-shipping teams
Connects directly to GitHub and GitLab, plus a CLI and API, so translation strings synchronize automatically with your repository instead of being edited by hand.
AI produces a first-pass translation and reviewers refine it, keeping quality high while reducing repetitive manual corrections over time.
Spot awkward wording in the live app and change it immediately, without leaving the page or filing a request with engineering.
Product managers, marketers, and translators can adjust copy on their own, freeing engineers from maintaining translation files.
AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
