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.
Git-native app localization for iOS and Android teams
Connect GitHub, GitLab, or Bitbucket and receive localization updates as pull requests and clean diffs on the branch you release from, so your repository stays the single source of truth.
Round-trip .xcstrings for Apple platforms and Android strings.xml without spreadsheet export, broken builds, or custom scripts.
Translate App Store and Google Play release notes and store listing copy in the same product, with platform-specific field limits and locale handling.
Protect brand terms, add tone guidance, and reuse glossaries so each new locale keeps the product voice users already know.
