Where each one falls short

Google Calendar

  • No AI-driven scheduling assistance or automatic meeting time optimization

  • No native task management or project tracking features within the calendar interface

  • Strict usage limits (maximum 60 calendars, 750 shares per time period)

Readwise Reader

  • There is no free tier, only a 30 day trial
  • Reader is bundled into the full plan rather than sold separately, so it cannot be had at the cheaper Lite price
  • The Lite plan at $5.59 a month billed annually is daily email review only, without the web app or tagging
  • Paying monthly rather than annually raises the full plan from $9.99 to $12.99
