Tettra is a real, purpose-built team wiki — if you don't already have a documentation home, it's a reasonable one to start with. It has its own editor, permissions model, and a Slack bot that searches existing Tettra pages.
ThreadExtract solves a narrower problem differently: it doesn't ask anyone to adopt a new tool. If your team already lives in Notion, ThreadExtract just keeps it fed — the "documentation" step is a single emoji reaction on a thread that already happened, not a task someone has to remember to do later. There's no second system to keep in sync, because there's only ever been one.
If you don't use Notion today, Tettra (or a similar dedicated wiki) is the more natural fit. If you do, ThreadExtract removes the step where knowledge dies in Slack because nobody got around to writing it up.
