KnowWhyy vs Slack AI.
Slack AI is the natural choice for questions about what was said in Slack. KnowWhyy connects that conversation to the pull request that implemented it and the Notion page that wrote it up.
The short answer
Slack AI's search answers work inside Slack, cite the messages they use, and come with Slack's Business+ and Enterprise+ plans. Below Enterprise+, they draw on Slack content only. KnowWhyy answers one question from Slack, GitHub and Notion together, which matters when a decision was argued in Slack but implemented and explained in a pull request.

FAQ
KnowWhyy vs Slack AI
Can Slack AI search GitHub?
Slack's help center lists GitHub among enterprise search sources, which is part of the Enterprise+ plan. On other plans, Slack AI search answers draw on Slack messages and files.
Does KnowWhyy work inside Slack?
Not yet. KnowWhyy reads the Slack channels you select, and you ask in the KnowWhyy web app. Each answer links back to the original Slack messages.
Does KnowWhyy read Slack DMs like Slack AI can?
No. KnowWhyy never accesses direct messages or group DMs. It reads only channels an admin selects, and private channels only after the KnowWhyy app is invited.
