Accent training with Hollywood coaches and real-time speech AI
Record a phrase and receive sound-level analysis of your pronunciation, word stress and clarity, with concrete tips on how to correct each error.
On-demand video lessons taught by coaches who have trained actors for major film and streaming productions, covering difficult sounds and connected speech.
Feedback is converted into targeted exercises so you rehearse the exact sounds and patterns you struggle with instead of generic repetition.
Simulated conversations let you rehearse real-world speaking situations such as meetings, interviews and small talk with instant correction.
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.
