Free Mac app that provides live transcription, AI assistance, and screen-aware context during interviews and meetings while keeping data local and private.
What it is
ExtraBrain is a free, local-first desktop AI interview and meeting copilot for macOS that helps users capture live transcripts, reason through high-stakes conversations, and organize session context while maintaining privacy. It provides live transcription via local NVIDIA Parakeet or optional Deepgram, on-device AI powered by Gemma, and support for bring-your-own providers including OpenAI, Anthropic, Claude, and Codex. The app runs as a Mac desktop tool rather than a meeting bot, staying hidden from screen sharing and screen recording. Users can maintain fully local workflows or choose external providers for transcription and AI models based on their privacy and workflow needs.
The product is designed for interview candidates, engineers, founders, students, and researchers during coding interviews, system design rounds, behavioral interviews, product meetings, lectures, and research calls. ExtraBrain Pro adds custom profiles, reusable prompt guidance, richer session history, post-session summaries, and premium model controls, starting at $9.99/month or $99/year, with eligible Pro subscriptions including 1,000 ExtraBrain AI credits monthly. The app is built around responsible use principles and supports thinking, accessibility, and preparation while respecting interview and workplace policies.
