Installation

Supported platform

ExtraBrain currently supports macOS on Apple Silicon and Intel Macs. Windows and Linux are planned, not current release targets.

Use the current Mac release when you need a desktop AI interview assistant, local-first meeting copilot, local transcription workflow, or provider-connected live assistant. Confirm hardware support before assuming on-device AI is available.

Install from GitHub Releases

1. Open the ExtraBrain download page.
2. Download the current macOS build.
3. Open the downloaded installer or app bundle.
4. Move the app into your Applications folder if the release instructions call for it.
5. Launch ExtraBrain once to confirm the app opens cleanly.

First launch checklist

• Confirm the app window renders normally.
• Confirm you can reach settings.
• Confirm any required microphone or accessibility prompts are completed.
• Confirm the release version matches what you expected to install.
• Review the current release notes for any published checksum, signing, or notarization details if your environment requires them.
• Confirm local transcription or optional Deepgram settings before a live call.
• Confirm on-device AI availability or provider access before relying on live answers.

Caution

Do not wait until five minutes before an interview to install the app for the first time. Test the release, permissions, local AI availability, and provider setup well before the live session.

After installation

Move to Set up AI providers and then Getting started if you have not already done that.
