A closer look at AI Error Wiki
AI Error Wiki is a free, unofficial reference for error messages and odd tool names that show up in ChatGPT, Gemini, Claude and Codex. Guides keep the exact wording, separate documented causes from user reports, and say when nobody knows.
What it does
AI Error Wiki starts from the assumption that you arrived with a line of text you didn't expect. It might be an error code, a tool name in a task log or a message that a long task stopped halfway. The site is built around searching that exact wording. Suggested searches on the homepage include claude 529, error in message stream and gemini error 1185, which gives a fair idea of the territory.
Each guide follows the same shape. It says what the message actually establishes, what you can try next, and what is still unknown. The About page describes the method, which starts with official product documentation and then compares the wording with original user reports. One person's fix gets labeled as such rather than presented as a cure.
The tool names section is the less obvious part. Names like file_gen:generate_pdf and file_gen:generate_document can show up while a file is being created, and the guide explains that seeing the name doesn't mean that step failed. It points you to check whether the file, a download link or a separate failure notice actually appeared.
Who it's for
It suits anyone using these assistants regularly who hits a message the product itself doesn't explain, such as a ChatGPT file that won't download or Codex reporting it's at capacity while you still have usage left. FAQ entries cover common questions like whether Claude 529 is a rate limit and how to tell if a service is down.
Limits
The site is independent and says it isn't official support. Coverage is limited to four products, and guides only exist for messages someone has added, though the search page lets you submit a missing one. The privacy policy says there are no advertising cookies or third-party analytics scripts, and that its own analytics records filter out things like API keys, email addresses and phone numbers before storage.
