Contact Book vs Kithmap

Contact Book is a personal CRM for capturing contact details, logging interactions and keeping track of gifts, life events and follow-ups. Profiles can hold emails, phones, companies, addresses, birthdays, social links, food preferences, allergies and how you met someone. A shared screen brings together profiles, a relationship graph, a timeline, life events, gifts, follow-ups and a journal. Users can import and export information, export everything or delete an account through self-service settings. The service is available on the web and offers HTTP API, CLI and MCP access to the same data and access rules. The operator says its application servers and database are hosted in Germany. Public endpoints use TLS 1.3, database disks are encrypted at rest, and backups are encrypted before leaving the primary host. Daily database snapshots are retained for 30 days, stored in another physical location, and restore tests are performed quarterly. The operator says it does not sell user data or share it with advertisers. Contact Book has a free plan; Standard costs €10 per month or €100 per year. Email and calendar sync are not offered.

Kithmap is a personal relationship CRM for keeping track of people and connections. Its graph lets users label links such as family, friends, partners, colleagues and classmates. People can be added by typing or pasting names, then organized with tags or groups and given photos and notes. Users can set a follow-up cadence, see who is overdue, record conversations and receive birthday reminders.

Kithmap describes itself as a single-user tool for personal memory, not a sales CRM. It runs on the web and macOS, and users sign in with Google. Optional connections to Google Contacts, Gmail and Calendar are subject to the access a user authorizes. Kithmap says Gmail thread bodies are not stored, although thread headers and relevant calendar events are cached on its server; for the Mac companion, message bodies remain on the Mac and only derived log entries are sent. Users can export data as JSON or delete an account in Settings. The open beta plan is free. Kithmap says it is US-only and not yet GDPR-compliant for EU residents.
