ExtraBrain: Your AI Interview Assistant for Live Interviews and Preparation

ExtraBrain is a sophisticated AI interview assistant built as a local-first desktop application for Mac users. It is engineered to offer candidates a real-time AI layer during live interviews and meetings. Unlike many AI tools, ExtraBrain operates directly from your desktop, ensuring a more integrated and private workflow. It provides a suite of functionalities aimed at empowering candidates, from live transcription of conversations to understanding screen-shared content and structuring coherent answers. With a focus on responsible AI use and user privacy, ExtraBrain aims to be an indispensable companion for anyone preparing for or participating in crucial professional discussions.

The primary benefit of ExtraBrain lies in its ability to provide contextual, real-time assistance during live interviews. It acts as an intelligent copilot, helping candidates to not only understand questions but also to formulate well-reasoned answers. The **screen-aware context** is particularly valuable, as it allows the AI to reference shared screens, code snippets, or documentation, providing more relevant support. This means that if an interviewer shares a piece of code or a diagram, ExtraBrain can help you analyze it in context. The **answer structure** feature can suggest ways to organize your thoughts, whether it's using the STAR method for behavioral questions or outlining a technical approach. By keeping a live transcript, candidates can also refer back to specific points or constraints mentioned by the interviewer, ensuring no detail is missed. This comprehensive support system reduces the cognitive load on the candidate, allowing them to focus on demonstrating their skills and knowledge.

Privacy and responsible use are paramount considerations for ExtraBrain. The tool is built with a **local-first** philosophy, meaning sensitive data can be processed on your device. Users have control over their data flow, with options for local Parakeet transcription and local Gemma 4 AI. When external providers are used, users are informed that selected prompts, transcripts, or context may leave their device. ExtraBrain strongly emphasizes that users must adhere to the rules and policies of the interview, employer, or platform regarding transcription, screenshots, and AI assistance. It is crucial not to use generated output to misrepresent skills, experience, or authorship. For sensitive material, reviewing the privacy and data flow pages before engaging in any AI workflow is recommended. When live assistance is not permitted, ExtraBrain can still be effectively utilized for practice and debriefing sessions.

ExtraBrain is designed to seamlessly integrate with the platforms candidates commonly use for interviews and meetings. It works with **Zoom interviews**, providing live transcription and screen-aware context without appearing as a bot in the meeting. Similarly, it supports **Google Meet interviews** without requiring the addition of a meeting bot or browser extension to the call. For **Microsoft Teams interviews**, ExtraBrain captures audio and screen context locally on your Mac. It also integrates with popular browser-based technical interview tools such as **CoderPad, HackerRank, and CodeSignal**, allowing candidates to follow live coding prompts, code, test outputs, and constraints directly within their workflow. This broad compatibility ensures that ExtraBrain can be used in most professional interview settings.

To begin leveraging the power of ExtraBrain, the first step is to **download the desktop app for Mac**. Once installed, you will need to grant the necessary audio and screen permissions. Following this, you can configure your AI settings, choosing between local or provider-based options based on your privacy preferences and needs. Before your first live session, it's recommended to open ExtraBrain alongside your chosen interview platform (e.g., Zoom, Google Meet, CoderPad). Familiarize yourself with its interface and test its features, such as the live transcript and screen context. Preparing your relevant documents and running at least one mock session is highly advisable to test audio permissions, provider settings, and the utility of your prepared notes under pressure. This hands-on approach ensures you can make the smallest possible improvement before your next important interview.
