KnowStack - AI-generated knowledge bases from your emails & docs

Hey Product Hunt! 👋 I built KnowStack because I watched team after team drown in the same problem: their company knowledge was scattered across Gmail threads, Slack DMs, Notion pages, and one senior person's head — and nobody had time to consolidate it. Existing wiki tools (Notion, Confluence, Guru) all assume someone on your team has time to write documentation. Most teams don't. And AI search tools (Glean, Dashworks) just search the mess — they don't fix it. KnowStack takes a different approach: connect your Gmail, documents, websites, and Slack — and AI generates a structured, searchable Knowledge Base from your existing communication. No one has to write anything from scratch. The KB stays current because it pulls from the work you're already doing. A few things I'm proud of: • Iterative AI generation — regenerate or expand sections without redoing the whole thing • Section-level permissions on every plan, not gated behind Enterprise • HR Tests — turn any KB into an AI-graded assessment for hiring or training (this one surprised me with how much teams love it) Free Starter plan if you want to try it. Professional is $29/mo, Business $79/mo — AI usage is transparent pay-as-you-go on top. 🙏 What I'd love feedback on: which data source is most painful for your team to wrangle? I want to know what we should prioritize next. — Edgar
