Pick GitBook if solo writers who will stay on Free $0, then buy Essential at $65/site/month billed annually plus $12/user when they need a custom domain, analytics, and AI Ask. Pick Notion AI if teams that already live in Notion and want draft, rewrite, and Q&A without leaving the doc. Skip Notion AI if people who only want a chat window (ChatGPT) or a one-shot deck (Gamma).
