Pros & Cons

open-design

  • Genuinely free, open-source core software with no mandatory recurring fee
  • BYOK option on the free tier gives technically comfortable users direct control over AI model costs
  • Flexible choice between self-managed API costs and simpler hosted credit plans
  • Free tier requires managing your own API key (BYOK) rather than a recurring model-credit grant
  • AI model costs (via BYOK) depend entirely on the chosen provider’s own pricing
  • Hosted Plus/Pro/Max plans require understanding model-credit consumption for accurate budgeting

ChatGPT

  • Largest user base and ecosystem of any AI assistant, with the most third-party integrations
  • Genuinely broad capability across writing, coding, research, and file analysis
  • Custom GPTs allow tailoring the assistant to specific repeated tasks
  • Frequent model updates keep it competitive on raw capability
  • Free tier has usage limits and access to a lower-tier model than paid plans
  • Can produce confident-sounding but incorrect information, especially without browsing enabled
  • Breadth can mean less depth than a tool purpose-built for one specific workflow
  • Data usage and training policies require attention for sensitive or regulated work
