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.
Uptime monitoring, on-call and status pages in one calm tool
Web and HTTPS endpoint checks with status code, keyword, response time and certificate validation, plus ping, TCP port, DNS record and mail server monitors — checked every 30 seconds from four regions.
Branching escalation paths decide who is notified, where and when, so severe alerts page someone immediately while warnings can wait for working hours.
Page the on-call engineer by SMS or phone call with one-key acknowledgement, and run the whole incident from Slack with /incident declare.
Publish branded status pages that follow every incident update, available in six languages and matched to the visitor.
