Full review →What is Notion AI?
Notion AI brings artificial intelligence directly into the Notion workspace, the popular all-in-one tool for notes, documents, wikis, and project management. Rather than switching to a separate AI tool, you invoke AI within any Notion page to draft content, summarize long documents, translate text, extract action items from meeting notes, auto-fill database properties, and answer questions across your entire workspace. The Q&A feature is particularly powerful: ask a question in natural language and Notion AI searches your entire workspace and synthesizes an answer with references to the source pages, making institutional knowledge instantly accessible. AI autofill generates database entries automatically, from summarizing linked pages to categorizing items and extracting dates. The pricing model is an add-on at $10 per member per month on top of your existing Notion plan, which means for a team of 10, the AI add-on alone costs $100/mo.
