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.

Kami

  • The free Basic plan exposes only about 10 of the 40 or more tools
  • Google Classroom, Schoology, Canvas and Microsoft Teams integrations require the Teacher plan at $149 per year
  • School and district licensing including domain wide deployment is custom priced and requires a quote
  • Non education users pay separate Workplace plans at $85 or $220 per year rather than the education rate
  • A dedicated account manager is only available on the School or District plan
