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.
