The problem it solves

Proposals and reports land in your inbox in every format imaginable, PDFs, images, and slides, and someone has to open each one and retype the details into a spreadsheet. That manual data entry is slow and easy to get wrong.

Who it fits

Operations teams and coordinators who receive documents by email from multiple sources.

How it works

  1. Every 30 minutes, the system checks Gmail for new emails from specified senders
  2. Each email is classified by type based on its content
  3. Attachments are processed based on their file format
  4. AI reads the document and extracts key details like dates, names, and amounts
  5. The extracted data is logged into Google Sheets and the email is labeled as processed

What you get

A structured Google Sheets record of every document's key details.

What you need

A Gmail account, an OpenAI API key, and a Google Sheets account.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
