KnowWhyy vs Notion AI.
Notion AI is a great assistant inside Notion. KnowWhyy is for the reasoning that never made it into a doc: the pull request review, the commit message, the Slack thread. It reads your Notion too.
The short answer
If your team works in Notion and pays for its Business plan, Notion AI can search your docs and connected tools and also write for you. KnowWhyy is narrower: it focuses on the history behind engineering decisions, including commit messages and review comments, and its free plan includes GitHub, Slack and Notion.

Which to choose
An honest recommendation.
Choose Notion AI if…
- Your team already lives in Notion and is on the Business or Enterprise plan.
- You want AI that also writes and edits pages, takes meeting notes and runs agents.
- You want to search code files, or connect tools such as Jira, Linear or Google Drive.
- You'd rather ask questions without leaving Notion.
Choose KnowWhyy if…
- The answers you need are in commit messages, pull request reviews and Slack threads, not just docs.
- You want GitHub and Slack included on a free plan.
- You want Slack DMs kept out of the index, whatever individual users choose.
- Not everyone on your team works in Notion.
They work well together: keep writing specs and decision records in Notion, and connect Notion to KnowWhyy so answers can cite those pages next to the pull requests and threads behind them.
