Character.AI
- +Enormous library of millions of user-created characters and a simple no-code character creator

- +Runs on its own proprietary models, and the free tier historically had no hard message cap
- -Assistant-only: characters respond in chat and take no actions, with no tools, browsing, or automation
- -No public API and a closed proprietary model, so it cannot be embedded in external workflows
Google Gemini
- +Deepest native integration with tools people already use (Gmail, Docs, Search, Android, Chrome)
- +Strong long-context and multi-step research with cited reports, plus open A2A and MCP interop
- +Massive reach and a generous free tier
- -Confusing, fast-changing branding (Bard to Gemini, features folded in and renamed)
- -The truly agentic mode is gated behind the top-priced tier and limited testing
