AI detection and writing verification built for schools and editors
Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.

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.
