AlliHat
AlliHat is a Safari sidebar for Claude, ChatGPT, Gemini, and Apple’s on-device AI on macOS. It lets you ask questions about the page you’re reading, explain highlighted text, and automate simple browser actions without leaving Safari.
Overview
AlliHat is a Safari sidebar for Claude, ChatGPT, Gemini, and Apple's on-device AI on macOS. It brings an AI assistant into the browser so you can ask questions about the page you are reading, explain highlighted text, or have the assistant take actions in the page itself.
The product is designed to remove copying and tab switching from common reading and browsing tasks. The homepage says setup takes about two minutes: install it from the App Store, enable it in Safari, and choose either a bring-your-own-key provider such as Anthropic, OpenAI, or Google, or Apple's free on-device AI.
Core features
Highlight-and-explain
Select any text on a page and get an explanation in place, which is useful for code, legal language, or academic writing.
Browser interaction
Let the assistant click buttons, fill forms, scroll, and navigate pages when you want it to handle multi-step web tasks.
Reusable workflows
Create repeatable workflows for tasks you do often, then run them with one click after setting them up once.
Persistent preferences
Store your role, preferences, and writing style so the assistant can remember how you like things handled in later sessions.
Conversation continuity
Continue a conversation after closing Safari and returning later, with the thread preserved where you left off.
Ways to use AlliHat
Reading and comprehension
Ask what a page means, summarize it, or question it while staying in the same tab and using the page as context.
Explaining selected text
Highlight a paragraph, term, or snippet and get an explanation right where you found it.
Hands-on web tasks
Ask the assistant to click through forms, scroll pages, and move between steps when a task needs basic browser automation.
Repeatable personal workflows
Save repeated browser workflows and preferences so the same routine can be run again without rebuilding it each time.
Longer-running browsing sessions
Return to an earlier Safari session and continue the same AI conversation from where you left off.
