The AI reads it, finds the actual cause, and writes the file, the line, and a patch — not just a summary. Send Chronexis the error and the stack trace. It returns the root cause, the exact file and line, and a remediation patch. Send us the error and the stack trace. Chronexis does the reading, the reasoning, and the write-up — you just apply the patch. POST the error and stack trace to `/v1/traces` . The AI reads it, finds the actual cause, and writes the file, the line, and a patch — not just a summary. Every ingested trace shows up on your dashboard the moment it lands, polled live — no refresh, no waiting for a batch job. Every trace is scoped to your API key. A crash that doesn't exist and one that belongs to someone else return the exact same answer — never a hint either way. Trial and Standard accounts diagnose on demand, within a monthly cap. Pro and Max get every crash diagnosed automatically as it arrives. Pro and enterprise tenants get their own AI key, so your diagnoses are never rate-limited by someone else's trial traffic. Every diagnosis ships with a suggested remediation patch and a prevention strategy — the fix, and how to stop it happening again. Free for 7 days, no credit card. Standard, Pro and Max are paid monthly plans — launching soon. Chronexis keeps the full error and stack trace, and streams back a structured diagnosis — so the actual bug is what you see first, not a guess at it. The raw error and stack trace are kept as sent — nothing sampled, nothing summarized away before the AI sees it. Five fields every time: summary, root cause, file and line, remediation patch, and a prevention strategy. Diagnosed, still processing, or failed — the trace page always shows you which, instead of nothing. Start a free trial with 10 on-demand diagnoses. No credit card required.
