Clay is gorgeous. We're sharper. Both are honest answers to the same question - here's how to choose.

Clay is the design-forward, AI-rich personal CRM with deep social integrations - LinkedIn, Twitter, calendar all woven into the contact card. Contact Book is deliberately quieter: no social ingest, no auto-enrichment, no inbox reading. We host in Germany. Pick Clay if the AI ingest is the value; pick us if you want a tool that does not read your channels (see how private your contact data really is).

Free plan, no credit card. We host in Germany. You can export and delete everything self-serve.
