In their own words
Contact Book
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.
Contacts+ Personal CRM
Contacts+ Personal CRM keeps a record for each person, with context and follow-up reminders for maintaining relationships. Records can include notes, tags, relationships, contact details, custom fields, birthdays, and important dates. Contacts sync in both directions with Google, iCloud, and Microsoft/Outlook accounts. Users can set reminders with due dates and snooze them, sync tasks one way to calendars, and receive a daily task digest email. The business-card scanner uses AI to transcribe cards and other images containing contact details into records. Premium and Teams add enrichment, duplicate detection and merging, profile photo matching, and outdated-data cleanup. An MCP integration connects the address book to ChatGPT, Claude, and Grok, with proposed changes awaiting user approval. The free plan includes one account, 1,000 contacts, daily sync, and web, iOS, and Android apps. Premium is $9.99 a month, billed 119.88 USD yearly; Teams is $12.99 a month, billed $155.88 per user yearly. The web app runs in a browser, and the maker says there is no separate native Mac or Windows app.
