Tettra's AI answers from what your team already wrote down.
Tettra's "Kai" bot searches your existing wiki content and answers questions in Slack or in-app. Verification and gap-identification workflows keep that content accurate over time. All of it depends on content someone already wrote and imported: Google Docs, other wikis, PDFs. If nobody's written the page a new hire needs, Kai has nothing to search.
A wiki needs pages before it can answer anything.
Tettra starts at $8/user/month with a 10-user minimum (tettra.com/pricing, checked 2026-08-03). Like any wiki, it's as useful as the pages your team writes and keeps current. Firstweek doesn't need anyone to write a wiki page first. It reads Slack, HubSpot, Salesforce, Confluence and Google Drive through read-only connections and writes the new hire's onboarding artifact from what's already there.
Firstweek doesn't replace your wiki.
If your team wants a lightweight, self-serve place to maintain its own documentation, Tettra is a good fit: simple to set up, easy for non-technical teams to keep current. Firstweek assumes you have something like it, or don't need one. It covers the weeks when a new hire needs an onboarding artifact, not a wiki to search.
Tettra makes your team's existing answers searchable. Firstweek writes up what's already in Slack and the CRM, through read-only connections, before anyone turns it into a wiki page.
Questions
Yes. Tettra is the self-serve wiki your whole team maintains. Firstweek writes one onboarding artifact per new hire, from Slack, Confluence, your CRM and its other read-only connections. They don't overlap.
No. If your team wants a lightweight internal wiki, keep Tettra. Firstweek doesn't connect to it. It reads Slack, Confluence and your CRM through read-only connections, and leaves Tettra where it is.
