How Tuck picks the right folder

How Tuck decides where to put your file

When you upload a file, Tuck follows a three-step process:

1. Extract content

Tuck reads the text from your file. For PDFs and Word documents it reads the text directly. For images and scanned documents it uses OCR. For spreadsheets it reads the cell values.

2. Classify with AI

The extracted text is sent to an AI model with a prompt that asks: which of Tuck's 15 document categories does this belong to?

The 15 categories are fixed and cover the most common document types people accumulate — things like invoices, contracts, medical records, and bank statements.

The AI only receives the text content of your file for classification. The text is processed under zero-data-retention terms and is never stored or used for training.

3. File into Google Drive

Once the category is chosen, Tuck creates the matching folder in your Google Drive (if it does not already exist) and moves the file there.

The folder structure looks like this:

My Drive /
  Tuck /
    Finance & Banking /
      invoice-march.pdf
    Medical & Health /
      blood-test-results.pdf

What if it gets it wrong?

AI is not perfect. If a file lands in the wrong category, see What if a file ends up in the wrong folder? for how to correct it.
