Muse is Meta’s new personal AI agent. It launched in September, and it now connects to even more of the apps you already use: your email, your calendar, your documents, your shop and your payments. It does not just answer questions. It books, buys, drafts and keeps working after you close the app.
It is a great idea. An assistant that can see your inbox and your calendar is far more useful than one that only knows what you type into it. But look at where the connection runs. Muse runs through Meta. Every app you connect hands a key to someone else’s platform, and what it produces from that access lives inside their product.
Same apps. Very different place for the keys.

A genuinely useful agent
Meta built Muse to do the work, not just talk about it. It connects to Gmail, Google Calendar and Outlook, to Google Docs, Notion and GitHub, and to shops and payments like Shopify, Stripe and PayPal. Meta has also opened a platform for developers to build more connectors.

Disconnect a connector, and what Muse already used “might still remain in Muse’s memories and your conversation history”.
Meta Help Centre, How Muse works with ConnectorsThat is a perfectly reasonable design for a personal assistant. For a business, it is the crux. Your client files, your pricing and your conversations can end up remembered somewhere you do not control.
You own the connectors
Instead of giving your connectors to an app, the connectors live in your own AI infrastructure, on your own accounts, in your own name. We set it up so you control what goes in, and you own what comes out.
You hold the keys
Every connection to your email, calendar, documents and CRM lives in one place you control. Grant it, scope it or revoke it without asking a vendor.
You choose what it sees
Access is given job by job. The system that drafts a proposal does not need your payroll, so it never gets it.
You own what it produces
Drafts, summaries, documents and decisions land back in your own systems. Change tools tomorrow and the work stays with you.
Proven tools, wrapped as one system
Each layer is best in class at its job, and every one of them is yours. Your team only ever sees one thing: Scalus IO. Tap a layer.
SCALUS IOThe business’s memory, in files you keep
In a rented app, memory lives on the provider’s side. In your own infrastructure it is a vault built in Obsidian: plain text notes, linked like a brain, sitting on your own machine. It is why the AI knows the business instead of guessing, and you can open it any time.
Written down
Calls, emails, decisions and procedures become plain notes.
Linked
Notes link to people, clients and jobs, like a brain.
Read first
Before it answers or drafts, the AI reads the notes that matter.
Written back
What it learns goes back in, so it gets better every week.
Installed on site, then it is yours
Tim comes to you, puts the whole system in, trains your team and stays on call. After that, the business runs it.

A personal trade is not a business one
For one person, handing an app the keys to a personal calendar is a fair trade. For a business it is a different question. Client files, pricing, contracts and conversations are the business. Professional firms carry confidentiality duties that do not stop at the edge of a convenient app.
And once your workflows live inside someone else’s platform, that platform decides what changes, what it costs, and what happens to your data. Owning the infrastructure means those decisions stay yours.
Scalus runs on exactly this setup today. If you like the idea of an assistant that knows your business, but not the idea of your business living inside someone else’s app, that is the conversation we like having.
