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