Connecting Claude or ChatGPT

Yab has no model of its own: it works on the Claude or ChatGPT plan you already pay for.

Everything AI in Yab runs on your own Claude or ChatGPT plan. Yab gives it a browser: your tabs, your sites, signed in as you. There is no Yab account, and Yab adds nothing to what your plan costs.

Connect#

  1. Open Settings › AI (or choose your agent in the welcome).
  2. Tick Claude, ChatGPT or both, and press Connect. Yab sets up what’s missing first.
  3. Sign in to your plan in the tab Yab opens. Yab never sees your sign-in: the agent keeps it.

Claude needs a Pro, Max, Team or Enterprise plan. ChatGPT works on Plus, Pro, Business, Enterprise and Edu, and Free and Go may too, with low limits.

What connecting puts on your Mac#

  • Claude Code or Codex, if they aren’t there yet: Anthropic’s and OpenAI’s own tools, which Yab runs for you on your plan.
  • The yab command, so you and your agents can use Yab from a terminal.
  • Yab’s skill and tools (an MCP server named yab-browser) in Claude Code’s and Codex’s own settings, so they use Yab when you ask them in their own app, too.

Settings › Developers shows where each went, puts a missing or older one right, and removes one at a time. Disconnect in Settings › AI › Agents takes back all of it, and only that.

Ask from Claude Code or Codex#

In a terminal or in their app, ask for anything on the web and name Yab’s skill:

use /yab-browser to open my GitHub notifications and tell me what needs me

In Codex the skill is $yab-browser. The agent opens tabs of its own in Yab, beside yours, and you can watch it work.
