Show HN: SpecSource – AI That Writes Linear Specs from Sentry, GitHub, & Slack (opens in new tab)

Hi HN, I'm Antoni. I built SpecSource to automate the tedious research you do for every new Linear ticket - matching with Sentry errors, finding the relevant code, searching Slack for context, checking for duplicates in Linear.

You connect your ticketing system like Linear to tools like Sentry, GitHub, Slack, and when a new ticket comes in, an AI agent cross-references everything and writes a structured specification. Takes about 30 seconds. The output works well as input for AI coding agents too.

Free tier: 100 credits/month (enough for ~20 tickets in my experience). Pro: $10/month for 1,000 credits.

Happy to answer questions about the approach or architecture :)
