Fix a file that won’t upload or process

If your file is rejected, stays processing, or cannot be read, use the checks below to get it ready for your Chat. Check the existing upload before adding another copy.

​

Check where the file belongs

• One conversation: attach it to that Chat.
• Several Chats in a Project: add it to the Project and wait until processing finishes.

See Give Chat the right context for choosing between these inputs.

​

Match the fix to the problem

Changing a filename extension does not convert a file into another format.

Confirm StefanBrain can read your file

Ask StefanBrain to identify the relevant section or summarize a small part of the file. Confirm it matches before requesting a larger analysis. If the problem repeats, email support@stefanbrain.com with the file type, size, upload location, and exact error. Do not attach confidential source files unless support specifically needs them and you are authorized to share them.
