What ExtraBrain is for

ExtraBrain is designed for live conversations where you need fast recall, structured prompts, and private AI assistance in a desktop app. It is available for Mac today, with Windows and Linux planned. On compatible hardware, on-device AI can keep model requests local; external providers remain optional. Common use cases include:

coding interviews
system design rounds
behavioral loops
dense customer or stakeholder meetings
lectures, research calls, and fast technical discussions

ExtraBrain is not a hosted meeting bot. It runs on your Mac, can use local NVIDIA Parakeet transcription, can use on-device AI when hardware supports it, and can connect to providers you control when external AI makes sense for the session.

Fast answers

Is ExtraBrain free?

Yes. The core Mac app is free to download and use. Pro adds workflow controls such as saved prompt presets, custom profiles, richer session history, post-session summaries, and advanced model controls where enabled.

Can ExtraBrain run locally?

ExtraBrain can keep model and transcription requests on the Mac when you use local transcription and on-device AI on compatible hardware. If you choose external providers such as OpenAI, Anthropic, Claude, Codex, custom endpoints, or optional Deepgram, selected prompts, transcript text, screenshots, notes, or audio can leave the device.

Is ExtraBrain allowed in interviews?

That depends on the company, interviewer, school, employer, or platform policy. Use ExtraBrain for note support, accessibility, preparation, and structured reasoning only where assistance is allowed.
