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.

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.

Plan posts on a drag-and-drop calendar, queue them in bulk, and route drafts through comment-and-mention approval flows before they publish.
Collect comments, DMs and reviews from all connected networks in one queue, then reply, label, assign to teammates and trigger DM automations.
Track performance, engagement and growth across 10 platforms, and send branded PDF reports that can be delivered automatically each week or month.
