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.

One sentence with an outcome, a number and a 14-to-180 day deadline becomes a written plan with dated milestones, up to three recurring workflows and a metric the agent tracks.
Each run opens a real browser session signed in as you, works inside the tools you connected, avoids contacting the same person twice and respects a configurable daily sending limit.
Progress figures are read from your connected tools rather than guessed, and what worked or failed is stored so later runs start where the previous one finished. A report lands each morning.
Beyond long-running goals, Katteb runs one-off tasks on demand and bundles unlimited chat, image and video generation within fair use on every paid plan.
