NovelAI

AI writing partner built specifically for fiction and novelists.

Sudowrite is an AI writing tool aimed at fiction authors, with a Story Bible for outlining, Write/Expand/Describe tools that draft in the author's voice, and a Canvas for plotting arcs and themes. Unlike general assistants, it is tuned for long-form creative narrative rather than business or marketing copy.

Self-hosted LLM chat frontend for power users, with characters and many backends.

A self-hosted, browser-based LLM frontend aimed at power users, with rich character cards, prompt control, extensions, and group chats. It runs as a local Node.js server on Windows, macOS, Linux, and Android (via Termux), connecting to many backends — OpenAI, Anthropic, plus local runtimes — using your own keys. Free and AGPL-3.0 licensed with no paid tier.

Chat with millions of user-made AI characters.

A consumer platform for creating and chatting with AI personas — fictional characters, helpers, and roleplay companions — across web and mobile. Hosts millions of community-built characters with voice calls and image generation on the paid tier. One of the largest conversational-AI roleplay products by usage.
