Understudy vs Tettra
The best wiki in the world can't capture what nobody wrote down.
The Empty Wiki Problem
Tettra is solid at what it does — it gives teams a clean, searchable place to store knowledge, with smart integrations into Slack and Google Docs. It even surfaces questions from Slack that nobody has answered yet.
But it still depends on someone sitting down and writing the answers. And the people who know the most are usually the ones who have the least time to write. Your senior engineer who's been on the team for seven years has critical knowledge about system architecture, vendor quirks, and historical decisions — but they're also the person running the most complex projects.
Understudy takes a different approach: instead of waiting for experts to write, it interviews them. A structured conversation that pulls out what they know and turns it into documentation automatically.

When to Use Which
Use Understudy when...

Use Tettra when...
- • You already have documentation scattered across tools
- • Your team asks the same questions repeatedly in Slack
- • You need a central, searchable knowledge base
- • People on your team willingly write documentation
