The engineer joining next quarter deserves to know why.
CollabVyn captures decisions from Slack, Notion, and Loom recordings into a searchable decision log your team actually uses.
Your team makes the decision once. Then makes it again — because the context disappeared into Slack. Knowledge debt compounds every sprint.
From scattered threads to searchable decisions
Three steps. No new workflows to force on your team. No training required.
What your decision log looks like
A structured, searchable record of every architectural call — with the original thread context always one click away.
Plugs into your existing workflow
CollabVyn connects to the tools your team already uses. No new workflows to force.
Built for engineering teams that move fast
New hire onboarding
When architecture decisions are searchable, new engineers self-serve context instead of interrupting senior teammates.

Async decisions made across time zones and tools have a single canonical home. Decisions don't disappear with the Slack thread.
Learn more →Engineering decisions
Architecture, API contracts, technology choices — every major engineering decision logged with full context. Stop relitigating the past.

"Our last infrastructure hire went from 'I don't understand why we did this' to fully productive in under two weeks. The decision log answered questions we'd have spent days in meetings explaining."
"We stopped having the 'why did we choose X over Y' debate for the third time. CollabVyn just… answered it. With the original Slack thread, the Loom from the spike, everything."
"Distributed teams accumulate invisible technical debt in the form of undocumented decisions. CollabVyn made that debt visible — and finally payable."
