Why writers pick Webnovels AI
Use the AI you already pay for
Sign in with your Grok or ChatGPT subscription, add a Claude API key, or run a local model on your computer. Webnovels AI sells no AI credits.
Book memory fills itself
When you accept a chapter, Webnovels AI records what changed: the characters, places, ranks and open plot threads. Bao reads these records before it writes the next chapter.
Author Voice scans your chapters
