ChatGPT

AI assistants

The default AI assistant, and still the one to beat for breadth.

Where it shines

  • Largest feature surface: browsing, image generation, voice mode, custom GPTs
  • Strong free tier to evaluate before paying, and a cheap Go tier below Plus
  • Huge ecosystem of guides, prompts and integrations

Where it falls short

  • Long-document work can feel constrained compared with rivals
  • Quality varies across the many features; the best parts are uneven
  • Four tiers now sit between free and $200, and the differences are metered rather than obvious

Our verdict

If you only try one assistant, start here, then test your real workload against Claude and Gemini before subscribing anywhere.
