extrabrain.app

ExtraBrain is a free, local-first desktop AI interview and meeting copilot built for moments where live context matters. It supports interviews, meetings, lectures, and research calls by capturing live transcripts and conversation context, then turning that signal into structured prompts, answer scaffolding, and follow-up questions while the session is still active.

Designed for clearer thinking under pressure, ExtraBrain helps organize what was said into usable session memory—saved facts, key topics, and post-session outputs like summaries and follow-ups. It’s especially useful for engineers and candidates who need help structuring coding prompts, system design requirements, behavioral answers, tradeoffs, and edge cases.

You can run ExtraBrain with on-device AI powered by Gemma and local Parakeet transcription, or connect provider access you choose (including OpenAI, Anthropic, Claude, Codex, and custom OpenAI-compatible endpoints). The app is available for Mac today, with Windows and Linux planned, and you can upgrade to Pro for advanced workflow and richer session history features.

What is ExtraBrain?

ExtraBrain is a free, local-first Mac desktop AI copilot for live interviews and meetings. It provides transcript-aware prompts and structured interview/meeting support, with session memory like saved facts and follow-ups.

Is ExtraBrain only for job interviews?

No—it's also designed for meetings, lectures, and research calls. It can help extract structured thinking from live conversation context, then leave you with organized outputs after the session.

Can ExtraBrain run with on-device AI instead of sending everything to the cloud?

Yes. ExtraBrain supports on-device AI powered by Gemma and local Parakeet transcription in a local-first setup. You can also choose to connect external providers, depending on your workflow and privacy needs.

Which AI providers can I connect?

ExtraBrain supports on-device AI powered by Gemma and can connect to provider options you control, including OpenAI, Anthropic, Claude, Codex, and compatible custom OpenAI-compatible endpoints. Optional Deepgram support is also available.

Does ExtraBrain join the meeting as a bot?

ExtraBrain is a desktop app designed to remain on your own Mac rather than joining the room. It’s built as a private live workspace for interview prompts and meeting notes, not a participant bot.

What does Pro add beyond the free version?

Pro adds advanced workflow tools and richer session history, plus post-session summaries for decisions, risks, and follow-ups. It also includes additional premium model and advanced workflow controls compared with Free.
