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.
Goal-driven AI agents that plan, work, and report while you sleep
Set an outcome and a deadline of 14 to 180 days, and the agent plans the work and runs it day after day toward the target metric.
The agent searches the web for buyers, decision-makers, competitor pricing, and channels, citing its sources before it drafts the plan.
Plans include up to three workflows that repeat hourly, daily, weekly, or monthly, such as prospecting and follow-ups.
Each run opens its own browser and acts in the accounts you connected, with daily send limits and duplicate contact protection.
