Character.AI
- +Enormous library of millions of user-created characters and a simple no-code character creator
- +Multimodal consumer experience: text, voice calls, group chat, image generation, and AvatarFX video
- +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
NovelAI
- +Strong tooling for long-form fiction: Lorebook, memory, author's note, and modules keep characters and world details consistent
- +Well-regarded anime and illustration image generation (NovelAI Diffusion V4.5) with inpainting, vibe transfer, and a built-in canvas editor
- +Few content restrictions and a privacy-first stance (encrypted text storage; generated images reportedly not retained on its servers)
- -An assistant, not an autonomous agent: the user prompts, curates, and edits every story passage and image
- -Image generation is metered by Anlas credits on most plans, and the strongest text model (Erato) is gated to higher tiers
