Yesterday I told you about the panic that hit me the night before my son's SAT. I'd given an unidentified company access to my Google account. I had no idea what it could see or do with it.

I mentioned this briefly yesterday, but I'd built this before.

The agent I built took hours of trial and error to wire up and lived inside Telegram, a messaging app. I gave it access to my Gmail and my Calendar. It could read, draft, edit, and delete emails. It could create and cancel calendar invites. All from a chat window I already had open all day, because I already use Telegram for everything else.

No external service sat in the middle. My bot talked straight to Google's own systems, using my own credentials. Every permission it had showed up right on my myaccount.google.com/security page, because I was the one who connected it.

That's the real difference between what I built and what instinct.co is offering right now. Instinct hands you a finished product and removes the friction. You just don't get to see who is on the other end of it. Building your own removes the mystery but you pay for it in hours instead.

If you want to try your own version, here's where I'd start.

1. Pick one task, not an assistant. Mine started as "let me ask manage my calendar." Everything else got added after that worked.
2. Use an interface you already check. Telegram, Slack, Teams, whatever you already have open all day. You don't need to build a new app. Start with something you use all the time.
3. Connect directly to the tool, not to a company that sits between you and it. Use Google's own login, or Microsoft's, so the access lives in your account settings, not someone else's.
4. Add one integration at a time. Gmail and Calendar first for me. Slack and Teams came later, once the first one felt boring, which is another way of saying solved.
5. Copy into Claude: "I want to build a personal assistant that can manage my calendar and my inbox. I want to build this in n8n. Walk me through the steps."

I slept fine the night I built that bot because nothing could go wrong, but because if it did, I'd know exactly who to blame.
