-
-### Create expense from receipt
-
-You can offer users to create expense by uploading a receipt. This feature relies on [OpenAI GPT-4 with Vision](https://platform.openai.com/docs/guides/vision) and a public S3 storage endpoint.
-
-To enable the feature:
-
-- You must enable expense documents feature as well (see section above). That might change in the future, but for now we need to store images to make receipt scanning work.
-- Subscribe to OpenAI API and get access to GPT 4 with Vision (you might need to buy credits in advance).
-- Update your environment variables with appropriate values:

-```.env

-OPENAI_API_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXX

-### Deduce category from title

-You can offer users to automatically deduce the expense category from the title. Since this feature relies on a OpenAI subscription, follow the signup instructions above and configure the following environment variables:
