Undetectable AI assistant for live technical interviews
The assistant transcribes the question as it is asked and returns a working solution you can read from the overlay, aimed at LeetCode-style prompts.
Captures and transcribes the interviewer's speech so the AI can follow questions delivered verbally during the call.
The window stays out of screen shares, dock, taskbar and the activity monitor, with click-through behaviour and a disguised process name.
Targets coding, system design, behavioural, full-stack, data, AI/ML, consulting, trading and product interviews rather than only algorithms.
Turn any text, PDF, image or book into lifelike AI speech
Voices trained on large language models deliver lifelike delivery, while Content Aware voices read the text and adjust tone to fit the material.
Speak in over 90 languages and create a custom multilingual AI voice by uploading or recording your own.
Read PDFs, Word documents, ePub, web pages and images, and scan physical books with the built-in OCR camera scanner.
Turn long readings into AI podcasts, get instant recaps, analyse screenshots and equations, chat with your document and generate practice quizzes.
