AlliHat - Claude AI in your Safari sidebar

Claude had a Chrome extension. Safari didn't. So I built AlliHat. Open the sidebar and it sees the page you're on. Ask anything. Highlight text for instant explanations. Agent Mode clicks, fills forms, and navigates. Workflows run repeated tasks in one click. Memory means you never re-explain yourself. History is saved per domain. Bring your own Claude API key, or use Apple Intelligence on-device. Your key goes straight to Anthropic. No tracking. No analytics. $29.99/year after a free trial.
