AI-native automation

Connect Slack and Trello with AI

Pick any two tools and Caddi runs the loop between them end-to-end — no complicated workflow builder, no IT ticket.

  • Doesn't break. Caddi reads intent, so when fields move or UIs change, your loop keeps running.
  • Screenshare to set up, chat to improve. Show Caddi once on a screenshare. Tweak it later by chat — no workflow builder to re-architect.

Common questions

How does Caddi connect Slack and Trello?

Slack and Trello just run together. All it takes is showing us how you use them — one screenshare, no workflow builder to wire up. Caddi turns the demo into a verified loop and runs it against Slack and Trello end-to-end.

Do I need engineering help?

No. Whoever does the work today shows it once on a call. Caddi builds the loop. No code, no IT ticket.

Is my data safe?

Yes. Caddi is SOC 2 attested. The AI watches and builds the automation, but once the loop ships it runs deterministically — no model in the loop at runtime.

Can Caddi connect Slack and Trello to other tools too?

Yes. Most Caddi loops span 3–6 tools. Once the first Slack + Trello loop is live, Caddi suggests other tools and other workflows to fold in.

How fast can it go live?

Typical first loops ship within a week of the screenshare. The Caddi team reviews every loop before it runs in production.
