Three steps from idea to prioritized risk report
Type /premortem in any channel. Give your session a topic and invite your team to join in the thread.
Team members submit risks directly in Slack. Then hit Generate risks — AI reads the context and surfaces additional risks your team may have overlooked.
Everyone rates each risk by likelihood and severity. Finish the session to get a prioritized summary — highest-impact risks at the top, color-coded for clarity.
Premortems work. We just make them easier to run.
Your team knows the domain. AI knows what tends to go wrong. Together you get a more complete risk picture than either could alone.
No new tool to learn or tab to open. Everything happens in the channel where your team already works.
Every risk gets rated on likelihood and severity. No HiPPO effect — everyone's vote counts equally, anonymously aggregated.
Session closes with a prioritized risk report — sorted by combined score, color-coded, ready to copy into your project doc.
A full premortem session takes 15–20 minutes, not a day. Run one before every launch, sprint, or big decision.
Each workspace gets its own installation. Tokens are encrypted at rest. No data is shared across teams.
Start free. Upgrade when you need more.
