Day with AI: Slack Is Dead, ntfy Lives. Plus Client Analysis Update.

What I worked on today

Monday. Two tasks, both more like maintenance and iteration. But important.

1. Slack → ntfy.sh migration + custom macOS notifications

Slack as a notification channel for Work-OS was overkill. I don't need a workspace, channels, or to pay for an API. I just need "send me a message on my phone and Mac."

Solution: ntfy.sh. Public pub/sub, no registration, works from curl. Migrated 5 n8n workflows (briefing, errors, blog reminder, issue notify). Entire migration took 2 minutes.

Bonus: wrote a custom Swift binary for macOS (`~/.work-os/work-os-notify`) — floating notification with sound, auto-dismiss. LaunchAgent runs in background streaming both topics (automation + GitHub issues). On iOS, just the ntfy app.

2. Client analysis update

Updated process analysis for a client — AS-IS state, Airtable stack, security audit. From 2 hours of manual work to 10 minutes with AI.

Time: AI vs without AI

Task	Without AI	With AI

Slack → ntfy.sh migration (5 workflows + custom notifications)	2h	2min
Client analysis update (AS-IS, Airtable, security)	2h	10min
Total	4h	12min

What I learned

• ntfy.sh is perfect for solo workflows. No setup, no account, works from CLI and n8n HTTP Request nodes. Ideal Slack replacement for Work-OS.
• Custom Swift notifications on Mac aren't as hard as they sound. One file, `swift build`, LaunchAgent. Floating window with timeout > default Notification Center.
