ChatGPT

Conversational AI Assistant
WHAT WE LOVED
  • Output quality at the frontier — GPT-5 tops LMArena Hard and most reasoning benchmarks
  • The ecosystem moat is real: custom GPTs, plugins, GPTs Store, ChatGPT-team workspaces
  • Voice mode in 2026 finally feels like a real conversation partner, not a parlor trick
  • Pricing per query is the cheapest at the consumer-Plus tier ($20/mo unlimited within rate limits)
  • Mobile apps, desktop apps, browser extension — covers every surface you'd want
WHERE IT FALLS SHORT
  • Hallucinations on niche factual queries still happen and the UI doesn't flag them clearly
  • Memory feature can drift over weeks; what it 'remembers' about you isn't always editable
  • Plus rate limits hit fast on heavy users, push you to $200/mo Pro tier
  • Enterprise privacy controls exist but are buried; defaults aren't no-train
  • OpenAI's product strategy shifts fast (deprecated models, changing UX) frustrates power users
