Pros
  • The free tier is real: unlimited everyday text chats, with uploads, images, voice and deep research included in limited amounts
  • Go at $8/mo gets you more messages, uploads and memory for well under half the price of Plus
  • Plus bundles reasoning models, projects, scheduled tasks, custom GPTs and Codex in one subscription
  • Deep integration with Gmail, Docs, Drive and Chrome
  • A cheap Plus tier at $4.99/mo, and Pro bundles big storage (reviews cite 5TB) plus Flow video credits
  • Long context for large documents
Catches
  • Free and Go may show ads. Plus ($20/mo) is the cheapest ad-free plan
  • No annual billing on Go, Plus or Pro, so no discount for committing
  • Most limits say 'limited' or 'expanded' rather than giving a number, so it's hard to know when you'll hit the wall
  • Usage limits are compute-based and opaque, refreshing every 5 hours with a weekly cap
  • Developers report shrinking practical quotas in AI Studio
  • Less compelling outside Google's ecosystem (per reviews)
