Contact Book vs Relatable

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.

Relatable is an AI-powered personal CRM for keeping context about important people and staying connected with them. It stores contact notes, tracks relationship health, offers follow-up reminders and AI-assisted drafts, and lets users search their network. Contacts can be grouped into Spheres by priority, each with its own stay-in-touch rhythm. Listed integrations include Gmail, Outlook, Google and Outlook Calendar, LinkedIn, iMessage, WhatsApp, phone calls, Zapier and MCP clients. Gmail email sync uses push notifications; Outlook and other providers sync near real time, according to the FAQ. Native iOS and Android apps support voice capture with Whiz, push notifications, network search and synchronization with a web account. Team features include shared profiles and Spheres, per-contact ownership and automatic de-duplication. Relatable also runs on macOS and offers a browser extension. Its plan costs $44 a month per user and includes unlimited contacts, team collaboration, and data import and export. There is no free plan, but a 10-day free trial does not require a credit card. The maker says data is encrypted in transit and at rest and users can export their data anytime.
