Meridian is an autonomous agent that lives on your Mac. It runs the research, watches the pages, drives the browser and works through the inbox — while you are somewhere else entirely.
“Watch this page and tell me when the price moves” is a complete instruction. No syntax, no trigger conditions to wire up, no fields to map.
02
It goes away and does the work
It opens the pages, reads them, keeps its own notes, retries what fails and tracks how far along it is. You can watch the progress or ignore it entirely.
03
You get the finished thing
A notification the moment your condition is met, and the actual result attached — the comparison, the draft, the number. Not a report on how hard it tried.
Most assistants hand you a paragraph about the work. This one hands you the work.
Find me a 14-inch MacBook Pro under $2,000 and tell me which one is actually worth taking.

Six retailers checked, three excluded on return policy, one flagged as a grey import. The full comparison is attached to the task — and it keeps watching in case something better appears before you buy.
You can always see what it is touching.
Your Mac, your tasks, your call. The agent asks before it reaches for anything, and it keeps asking.
Every permission is shown in plain words before it is used — not buried in a settings tree you have to go find.
Connect one service, or none at all. An integration that is switched off is genuinely not reachable.
Revoke anything at any moment from a single screen, and see exactly what each task did while it was allowed.

Anything on macOS 12 or later, on both Apple silicon and Intel. Older machines will install it, but long browser tasks are noticeably slower on pre-2018 hardware.
You get a signed disk image. Open it, drag the app into Applications, and launch it. macOS will ask you to confirm the developer the first time, and the app will ask for the specific permissions it needs as you use them. Nothing runs in a terminal, and nothing installs itself in the background.
Only what the features you have switched on require, and only after you have granted it. Each task keeps a log of what it opened and what it changed, so you can go back and check. Switch an integration off and that access is gone.
Yes, for the reasoning steps. Anything that reaches outside your machine — loading a page, checking a shop, sending mail — still needs a connection, whichever model you point it at.
No. Install it and start a task. A licence key arrives by email when you buy, and you paste it in once — there is no account to create and no profile to fill in.
For almost everything, yes — the work it does is mostly out on the web. It keeps its queue and its notes locally, so a dropped connection pauses a task rather than losing it.
Drag it to the Trash like any other Mac app. If you want the task history and settings gone too, there is a one-click Remove all local data button in Settings before you delete it.
