A wall-of-text stack trace when you just want the one line that matters
“A 200-line stack trace dumps in my terminal and 90% is framework noise. I want the actual cause and the file I should open, highlighted.”— Hacker News ↗
The gap
IDEs show traces raw; AI chats help but lose the focused 'cause + your-code frame + likely fix' framing. A purpose-built trace triage that points at YOUR frames (not node_modules) is a tight, useful niche.

Paste-ready build prompt
Build a stack-trace decoder in Next.js. Paste a trace; highlight the most likely root-cause line, separate the user's own code frames from library noise, and have an LLM give a one-paragraph cause + suggested fix. First 3 steps: (1) paste box + language auto-detect, (2) parse/group frames (app vs vendor), (3) an LLM pass returning `{cause, likelyFix, keyFrame}` rendered above a collapsible full trace.
