Pros

  • Generous free tier to test the experience before paying

Cons
  • Underlying model quality varies and trails frontier chat models
  • History of content-filter and privacy controversies
  • Not really useful as a serious writing or productivity tool
  • No public API; closed end-user product only
  • Anki sync is one-way only
  • Free tier capped at 30 AI notes per month
  • AI-generated cards still need human review for accuracy
  • Smaller ecosystem than Anki's plugin world
