ExtraBrain is a macOS-first live AI assistant designed to support interviews, meetings, lectures, research calls, and technical discussions. It captures live context during conversations—transcribing speech, recording screen context, detecting topics, providing structured AI analysis, generating follow-up questions, saving key facts, and logging post-session history. Its primary users include engineers, job candidates, students, founders, product managers, researchers, meeting leads, and anyone seeking clearer thinking during high-pressure conversations. For job seekers, ExtraBrain helps organize coding interview prompts, system design requirements, behavioral responses, edge cases, tradeoffs, and follow-up questions. For meetings, it extracts decisions, risks, owners, action items, customer pain points, and summaries. ExtraBrain is local-first by design; transcripts, prompts, screenshots, notes, and session history can remain on the user’s Mac with a local setup. Users can connect to trusted AI providers, including OpenAI, Anthropic, Claude, Codex, custom OpenAI-compatible endpoints, and local options such as Gemma 4 when installed and compatible, Parakeet transcription, or optional Deepgram. ExtraBrain is available for Mac today, supporting Apple Silicon and Intel Macs; Windows and Linux support are planned. The app is free to start, with optional Pro features for advanced profiles, richer session history, summaries, and workflow controls.
