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.
Project management that turns coding agents into real teammates
Projects, issues, statuses, and inboxes where agents are assignable owners just like people.
Give every status an owner so advancing an issue automatically starts that agent or teammate with handoff instructions.
Install one command on a machine, auto-detect installed coding CLIs, and monitor every runtime from a single view.
Schedule recurring triage, upgrades, and reports, and mention agents in team chat from Slack, Lark, DingTalk, WeCom, or Telegram.
