Contact Book: the alternative to Dex
What moving from Dex to Contact Book actually looks like in 2026.
Contact Book is what people use when Dex stops fitting. Below is the honest side-by-side - same product surface, different posture: hosted in Germany, no third-party trackers, one honest price - plus the migration mechanics that decide whether the switch lands in an evening or in a quarter.
At a glance
Dex is sharply focused on "don't lose touch" - it adds reminders + activity tracking on top of LinkedIn-style integrations. Contact Book does that too, and adds gifts, life events, pets, family relationships, and a journal. If keep-in-touch reminders are 80% of what you want, Dex is excellent. If you also remember birthdays, family details, gift histories, and want all of it in one place, you're more at home with us.
Switching
What moving from Dex actually looks like
The switch goes in three rough phases: export from Dex, import into Contact Book, and reorganise what came over. Most people allocate an evening for it. The export side is where the time goes - Dex hands you a CSV/JSON dump and the field mapping isn't always obvious; once that's resolved the import is a couple of minutes. We don't paywall the import path or pretend it's a pro-only feature, and you can run both side-by-side while you decide.

When to pick which

Pick Dex when
Export from Dex
Find the export option in Dex's account settings. Most tools provide a CSV or JSON download. Save the dump locally - that's the source of truth for the next step.
Map fields in Contact Book
Open the import tool in Contact Book. Dex's field names rarely match Contact Book' 1:1; the import flags any unmapped columns so you can pair them up before anything commits.
Run the import
Run the import. Contact Book shows a preview of the first parsed rows in the import dialog so you can sanity-check the column mapping + a sample of records before anything commits. If you're nervous about a large dump, import a small subset first, verify it landed the way you expected, then run the full file.
Re-create your views, tags, saved searches
Dex-specific UI metadata (custom views, saved filters, in-app annotations) doesn't transfer with the data export. Spend an evening rebuilding the views you used most - usually a 30-minute job once you've done it once.
Cancel Dex when you're confident
Run both side-by-side for a couple of weeks if you want to be sure. When you're confident, cancel the Dex subscription from their side. Contact Book keeps your export option self-serve in account settings - no lock-in either direction.
