Open the Apple menu and choose About This Mac to find your chip. Choose Apple silicon for an M-series chip or Intel for an Intel processor. Open the downloaded disk image and drag Chief of Staff into Applications, then launch it from there.
Use a Windows 11 Intel/AMD PC. Windows ARM is not supported in this alpha. Run the downloaded installer and follow its prompts.
Check the signing information beside your download. If your computer blocks installation, contact Mark. Do not disable security features to install it. Use a workspace you can safely experiment in and keep your normal backups.
The alpha is free and does not require AI-Powered Executive membership. Pricing after alpha is not yet set. AI-Powered Executive members will get full access at no extra cost.
Use Claude with access to Claude Code or ChatGPT with access to Codex. Your subscription’s usage limits apply. Claude Code must be installed separately. The app guides you through connecting your choice.
Create or sign into your Chief of Staff account in the app and verify your email. This activates the app and is separate from your AI subscription. Choose which Google Workspace or Microsoft 365 email and calendar accounts to include.
To update, quit Chief of Staff and install the newer build from this page or your invitation. Keep your workspace and app profile. Check with support before downgrading.
Your Markdown memory stays in your local workspace. Relevant information is processed by your connected AI provider. Account services, usage and health reporting and submitted feedback use Chief of Staff’s backend.
If work stops, check Work in the app for progress or a recovery action. If that doesn’t help, send feedback or email Mark. Don’t delete your workspace to troubleshoot.
When reporting a problem, include what you expected, what happened and your app version. You can review diagnostic logs before sending or leave them out. Check attachments for information you don’t want to share.
