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.

An all-in-one platform for students to manage studies and stay motivated
Capture coursework, assignments and revision into a single list so nothing depends on memory or scattered notes.
Pomodoro-style timing and planning tools help structure sessions and keep the workload spread evenly rather than piling up before deadlines.
Set study goals and track progress against them, which turns a vague intention to 'work harder' into something measurable.
A student community provides peer context and accountability, which is often what keeps motivation going through a long term.
