Install Claude Code

Claude Code is the engine Hyo runs on. If it’s not on your computer yet, Hyo sets it up for you — you don’t need to touch a terminal or copy any commands.

Watch the install guide

If you’d rather follow along than read, here’s the full setup, start to finish. It’s the same video that’s built into Hyo’s welcome screen.

Let Hyo set it up for you

When you first open Hyo and Claude Code isn’t ready, Hyo shows you a setup screen. There are two buttons, and that’s the whole job:

1. Install Claude. Hyo installs Claude Code in the background. Nothing opens, nothing to copy — you’ll see it say “Installing…” and then that it’s done.
2. Sign in to Claude. A browser tab opens asking you to approve with your Anthropic account (the same login you use at claude.ai). Approve it, and that’s you signed in.

Once both are done, Hyo drops you straight into the chat. If it doesn’t, click Re-check.

You can get to the same buttons any time from Settings → Hyo Claude Code Agent → Setup.

You’ll need a Claude account

Claude Code runs on a Claude Pro, Max, Team or Enterprise account. If you don’t have one yet, sign up at claude.ai first.

Prefer to do it yourself

If you’d rather install it by hand, run one command in your terminal:

• Mac or Linux: curl -fsSL https://claude.ai/install.sh | bash
• Windows: irm https://claude.ai/install.ps1 | iex

Then come back to Hyo and click Re-check. Hyo finds it, and you sign in with the button as above.

When it’s done

Press Cmd+Shift+H (Ctrl+Shift+H on Windows) to open the chat, and send a message to check Claude replies.

Next, the thing that makes Hyo actually useful: setting up your workspace. Or if you just want to see it work, jump into your first conversation.

Something not working?

If Hyo can’t find Claude, or says it’s installed but won’t start, open Settings → Hyo Claude Code Agent → Setup and click Auto-detect. It runs Claude to check it really works, and tells you whether you need to install or just sign in. More in Troubleshooting.
