AI orchestrator for real browser work on your desktop
Connect the AI agent you already use—such as Claude Code, Codex or another local CLI agent—and let it drive real browser sessions from your desktop.
Manage multiple accounts per platform with anti-fingerprinting, residential proxies, isolated Chromium profiles and remote-browser logins that avoid sharing passwords.
Save a workflow as a repeatable skill and schedule recurring browser jobs to run 24/7 while the desktop app stays open.
Use anti-detect Chromium, a Camoufox Firefox engine and Android fingerprints via Multilogin to cover desktop and mobile-style scenarios.
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.
