All-in-one AI assistant across web, browser, desktop and mobile
Chat with a rotating roster of leading LLMs from OpenAI, Anthropic, Google and others, switching models per task without separate subscriptions.
Works on Chrome and Edge to summarize pages and YouTube videos, explain or translate selected text, and assist with writing directly inside any web page.
Rewrite, humanize or generate text, get full-page bilingual translation, and chat with or translate PDF documents.
Create images, convert image-to-image, animate stills, remove backgrounds or watermarks, and generate logos and avatars.

Give every AI agent its own isolated browser with a persistent identity
Each profile is generated from a seed so its identity, cookies and logins persist across restarts, and sites see the same returning visitor rather than a new device.
One browser per profile means separate logins, cookies and devices that share nothing, making multi-account automation safe to run in parallel.
Agents get through username and password forms, email confirmation codes, TOTP and SMS two-factor codes, passkeys and permission prompts without stalling.
Press-and-hold, image grid, slider and rotation captchas are solved through human-like input rather than third-party solving keys.
