FeelFish is an AI-assisted writing platform designed for novelists and other creators working on long-form fiction. Its desktop software brings chapters, characters, settings, and story context together in a single project workspace, helping writers collaborate with AI while keeping their material organized. Authors can build character profiles and world settings, manage story information, and use context memory to support continuity in plot and style.

FeelFish also lets users configure specialized AI departments, such as editorial, review, and character-advisor roles, and create multi-agent workflows in which different assistants contribute to a project. Skills and agents are also available through its resource market. The platform supports models including DeepSeek, ChatGPT, Gemini, Grok, Douban, Qwen, and Kimi.

FeelFish is available as a desktop client for Windows, macOS, and HarmonyOS PC, with companion mobile apps for browsing work, capturing ideas, and remotely controlling desktop workflows. It can also support script development, including character notes, scene outlines, dialogue drafts, and revisions, while writers retain control of creative decisions
