Show HN: I built free Slack app that remembers every incident for on-call heroes

https://www.robinrelay.ai
1•alibasharat5•2h ago
Hey HN,

If you’ve been on-call, you know the drill. Pager goes off at 2 AM. You scramble into Slack, scroll through half a dozen threads, and realize… this exact alert happened three months ago. Someone debugged it, found the root cause, maybe even fixed it but that knowledge is buried somewhere in the channel history. So you start from zero. Again.

That’s the pain we’re tackling with RobinRelay: a Slack-native assistant that remembers everything your team has already done during incidents and brings it back right when you need it. DEMO Video: https://www.youtube.com/watch?v=MHWsOZa0Gpc

Here’s how it works today:

When an alert is posted in Slack, RobinRelay checks if we’ve seen it before.

If yes, it replies in-thread with past triage notes, root causes, and who fixed it all pulled from your actual Slack discussions, 6-month old messages.

- It builds a knowledge base entirely from your team’s Slack history (no extra tools or documentation effort).

- Weekly digest in Slack: most recurring alerts, top noisy services, most active responders.

- Interactive RAG agent: you can DM RobinRelay or mention it under any alert and ask questions like “What usually causes this?” or “Has this happened in staging before?”

We don’t hide or suppress alerts — we work with the alerts you already have, giving you instant context and history without changing your existing monitoring setup. We integrate with any alerting tool because we work with Slack API rather than Tools API's, it removes the burden of integration with thousands of tools.

You can see alert summaries and heatmaps in the Slack App Home, it will help your team to improve alerts by seeing most frequent/noisy and we’re experimenting with features like auto-linking alerts to related services and proactive “should I remind you?” prompts.

We’re still early and would love feedback on:

Do you also discuss solutions/investigations in alerts channels of Slack? Do you spend time finding old messages? Would you like to have senior SRE co-pilot in your pocket while you are having coffee on Weekend?
