AI Error Message Explainer
Explain an error message, its likely cause and how to fix it.
Offline engine active
This tool answers immediately from a built-in engine. Connect your own OpenAI-compatible provider for richer answers.
Error or stack trace
0 charsExplanation
Paste an error and run the offline explainer. It matches your text against a knowledge base covering JavaScript, Node.js, Python, Go, Java, databases, containers, Kubernetes and the network stack.
Model-assisted explanation
Optional. Connect your own OpenAI-compatible provider above and this panel sends the same input from your browser to your model for a longer, context-aware explanation. Without a provider, the offline result is the whole answer.
About AI Error Explainer
Error messages are written for the person who wrote the code, not for the person reading it at midnight. Almost every message contains three separable pieces of information: what the runtime detected, which invariant was violated, and which part of your input caused the violation.
This explainer matches the text you paste against a knowledge base of common errors across JavaScript, Python, Go, Java, containers, Kubernetes, SQL and HTTP, then presents the meaning, likely causes, ranked fixes and a short example. If you connect your own model provider, it will additionally produce an explanation tailored to the code you paste.
How it works
- The input is scanned for known error signatures, including runtime messages, exception class names and stack frames.
- The detected language or platform is identified so the guidance matches your toolchain.
- Causes are ranked by how often they actually produce that error, not by theoretical possibility.
- Each fix is written as a concrete change, with a short code example where one helps.
- The knowledge base covers Node.js, browsers, Python, Go, Java, Docker, Kubernetes, PostgreSQL, MySQL and network stacks.
- With a provider key configured, the same input is sent from your browser to your model for a second, context-aware explanation.
Input and output
Accepts
A raw error message, exception, compiler diagnostic, container exit reason or stack trace.
Produces
What the error means, the most likely causes, ranked fixes, an example and follow-up checks.
Privacy
The offline engine runs entirely in your browser. Input is only transmitted when you explicitly enable your own AI provider.
AI Error Explainer FAQ
Does this replace reading the stack trace?
No. It is a fast first pass that points at the part of the trace and the code path worth checking. The frame list is usually the fastest path to the real cause.
Why does the explanation mention causes I already ruled out?
Because the message alone often cannot distinguish root causes. The list is ranked by frequency; if you have already excluded the first, work down the list rather than dismissing the tool.
Which languages are covered?
JavaScript and TypeScript in both browser and Node.js, Python, Go, Java and the JVM, Rust, plus container, Kubernetes, database and HTTP errors.
Can I analyse an entire log file?
Paste a single failure at a time. A whole log file usually contains multiple failures, which dilutes the analysis.
