AI grammar, spelling and style checker for 30+ languages
Detects grammatical errors, typos, punctuation issues and casing mistakes across 30+ languages.
Rephrase any sentence to be more formal, fluent, simple or concise with AI-driven suggestions.
Browser add-ons plus Google Docs, Word, LibreOffice, Gmail and Outlook integrations, and desktop apps.
Advanced suggestions flag overused phrases, redundancy and wording that weakens your text.

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.
