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.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
