Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Day One

  • It moved from a one-time purchase to a subscription after the Automattic acquisition, so long-term cost is materially higher than the original pricing implied.
  • The free tier caps at one journal and 25 photo entries, which is restrictive enough that anyone journalling seriously for more than a few weeks needs to pay.
  • End-to-end encryption is opt-in per journal rather than on by default, so users have to actively choose it and understand which journals are protected.
  • Cancelling Premium after using multiple journals or heavy photo storage can leave content viewable but with sync and some features disabled, so people should export before cancelling.
  • As an Automattic product, its roadmap sits behind a company whose primary focus is WordPress and Tumblr, not journalling specifically.

Nitro PDF

  • Specific per-seat pricing is not published; must contact sales for individual plan pricing and volume discounts
  • SSO and enterprise features (Azure Information Protection) are limited to Plus tier, not available in Standard
  • Plans support up to 20 licenses online; teams needing 20+ users must contact sales
