Ask your company why.

KnowWhy connects GitHub, Slack and Notion into one searchable knowledge base. Ask why a decision was made or what shipped last week — and get a straight answer that cites the commit, thread or page it came from.

Free plan · Read-only access · You choose what gets indexed

Example: asked “Why did we move card capture to a hosted checkout?”, KnowWhy answers in plain language with numbered citations to Payments decision record, #payments thread, #482 Hosted checkout.

Illustrative example. Real answers are generated only from your own connected sources.

The problem

Knowledge is scattered. The context behind it disappears.

Decisions are argued in Slack, implemented in GitHub and written up — sometimes — in Notion. KnowWhy brings them together so the next person doesn't have to dig.

Answers you can verify, line by line.

Every claim carries a numbered citation. Click it to read the exact excerpt, then jump to the original commit, thread or page. Citations that don't map to real evidence are stripped before you ever see them.

Card capture moved to a hosted checkout after mobile 3-D Secure failures1, agreed in #payments2.

Understands “last week”

Relative dates resolve in your organization's time zone, and the searched range is shown above every answer.

Meetings, next

Transcripts are on the roadmap. Today, notes captured in Notion or Slack are fully searchable.

Engineering

Commits, pull requests, reviews and issues — who changed what, when, and the reasoning in the description and review thread.

Communication

The Slack discussions where decisions actually happen, kept together with their thread replies.

Documentation

Specs, decision records and meeting notes in Notion, with page history and links back to the source.

How it works

From scattered tools to a straight answer in three steps.

  1. 01

    Connect your tools

    Install the GitHub App, add KnowWhy to Slack, or share pages from Notion. You choose exactly which repositories, channels and pages are indexed.

    read-only · least privilege
  2. 02

    KnowWhy indexes in the background

    Content is normalized, chunked and embedded incrementally. Edits and deletions are picked up through webhooks and scheduled syncs — deselect a source and it leaves retrieval immediately.

    #payments · threads
    Engineering wiki · pages
  3. 03

    Ask in plain language

    Get a concise answer with numbered citations. Click any citation to see the excerpt and open the original commit, thread or page. If your sources don't say, KnowWhy says so.

    “The retry loop was removed in #4823after the team agreed in #payments2…”

Security

Built for confidential information.

Treat every connected source as confidential — so we do too. Here is how KnowWhy is designed.

Isolation in the database

Every record carries its organization, and PostgreSQL row-level security enforces tenant boundaries — not just application code.

Source-level access

Workspace membership doesn't unlock everything. Private repositories, channels and pages stay restricted until an admin grants access.

Encrypted credentials

Integration tokens are encrypted with AES-256-GCM using keys kept outside the database, and are never sent to the browser.

Answers you can verify

Citations map to real indexed sources the asker is allowed to see. When the sources don't contain an answer, KnowWhy says so.

Least-privilege integrations

Read-only permissions, minimal scopes and revocation on disconnect. We document exactly what each integration can access.

Audited administration

Connections, role changes and access grants are recorded in an audit log available to owners and admins.
