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.
Turn long videos and audio into short text summaries
Works with links from YouTube, Vimeo, Facebook, Google Drive, Dropbox, Twitter, Telegram and other supported sites, so you don't need to download the file first.
Upload video or audio files stored on your laptop or phone and get the same summary output without hosting them anywhere publicly.
Built to summarize files up to roughly three hours, covering full lectures, webinars and lengthy meeting recordings.
The goal is to strip unnecessary detail and surface the key points, so the summary reads faster than a raw transcript.
