About this tool

Translate an opaque error into what it means, the likely causes, and a concrete check for each.

Some error messages describe the symptom at the point everything fell over rather than the cause, several frames earlier. A null reference deep inside a framework tells you where it broke and almost nothing about why.

Paste the error, with the stack trace if you have it. You get what the message actually means in plain English, the likely causes ordered by how often they turn out to be the culprit, and a specific check for each one — an actual command or file to look at rather than "check your configuration". Where the message is genuinely ambiguous, it says what extra information would narrow it down instead of picking a cause and sounding certain about it.

How to use

  1. Paste the full error including the stack trace, then add your language or runtime and what you were doing when it appeared
  2. Press Generate and give it a few seconds.
  3. Copy what you need, or generate again for a different take — every run is fresh.

Frequently asked questions

Yes — it is usually the most informative part. The message says where things failed; the trace shows the path that got there, which is where the actual cause tends to sit.

Add what you were doing when it appeared and any recent change — a dependency update, a config edit, a deploy. Context narrows the possibilities more than the error text alone.

Traces often contain file paths, environment values and occasionally credentials. Redact anything sensitive first — the text is sent to the AI provider to generate the answer.

No. Your input is sent to the AI provider this site is configured to use purely to generate your result, and is not stored here afterwards. There is no account for it to be attached to. Even so, keep passwords, financial details and other people's private information out of it.

The site owner selects one model that powers every tool here, so there is nothing for you to configure. Describe what you need, press Generate, and read the result before you use it.
