ExtraBrain runs as a desktop app on your Windows PC. It follows live interviews with transcription and screen-aware context, helps structure coding, system design, and behavioral answers, and keeps session history for review afterward.
ExtraBrain is a free, local-first AI interview assistant for Windows. Download the installer from the download page, or get it from the Microsoft Store. It offers the same core workflow as the Mac app: live transcription, screen-aware context, interview profiles, bring-your-own AI providers, and post-session review.
Download the Windows installer from the latest release, or get ExtraBrain from the Microsoft Store, which keeps it up to date.
The core Windows app is free. ExtraBrain Pro adds automatic answers, custom profiles, and full session summaries, with a 14-day trial and no card.
Connect OpenAI, Anthropic, Claude, Codex, or a compatible endpoint, or use ExtraBrain AI credits that come with Pro plans.
ExtraBrain runs on your PC instead of joining Zoom, Microsoft Teams, or Google Meet as another participant.
Get ExtraBrain from the Microsoft Store or the download page, then open it before your interview.
Pick a transcription option and an AI provider in settings, then run a short rehearsal to confirm audio and screen capture.
ExtraBrain transcribes the conversation, reads visible context such as code or a design prompt, and suggests clarifying questions and answer structure.
Use session history to see what was asked, where answers were weak, and what to prepare for the next round.
Follow prompts, constraints, and test output in browser-based editors and desktop IDEs on Windows.
Track requirements and tradeoffs while you talk through architecture on a whiteboard or diagram tool.
Turn questions into STAR outlines grounded in your own notes and experience.
Rehearse with the same app you will use later, then review the transcript and feedback.
Run ExtraBrain alongside Zoom calls with live transcription, screen-aware context, and a desktop window designed to stay hidden from screen sharing.

Follow live coding prompts, code, test output, and constraints in common browser-based technical interview tools.
A desktop app can follow audio and screen context across Zoom, Teams, editors, and docs instead of living in one browser tab.
