Troubleshooting

A value is null

The AI could not find it in the text. Check the document, or name the field the way the document labels it.

"You have reached today's limit for AI tools"

The daily AI allowance is used up. The message says when it resets; browser-based tools keep working meanwhile.

"The AI gave an answer in the wrong format"

The model's reply could not be read. Click the button again; it usually works on the second try.

Frequently asked questions

Can it make up values?

It is told to copy values exactly and use null when a value is not in the document. Check totals and dates against the original.

What happens to my text?

It is sent through our server to an AI provider to produce the answer, then discarded. We do not store it or use it for training.

Which AI does it use?

A provider such as OpenAI, with Anthropic as a backup, chosen by us. Your text is processed to write the answer and is not stored by us.

Is it free?
