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.
note.md — Reading Studio
A side-by-side dual-pane reader that puts the PDF and your markdown editor next to each other, so highlights and annotations become part of your notes as you read.
Generate BibTeX or APA citations from PDF metadata, with every citation linked back to the exact highlight it came from so you can return to the passage months later.
A premium feature that searches your library by meaning rather than exact keywords, powered by on-device models so nothing is uploaded.
Bidirectional links between notes and sources build a visual relationship graph that can be exported in a Neo4j-friendly format.
