Which document types work best with Builder?

Last updated: March 9, 2026

PDFs and emails tend to yield the best results due to their structured format. Scanned images or handwritten documents may require more manual review, though Drumkit's OCR capabilities are continuously improving to handle a wider range of document types.

Here's a quick breakdown by document type:

  • PDFs & Emails: Best performance — structured format allows Builder to extract load data accurately and efficiently.

  • Scanned Images: Good performance — may require some manual review depending on scan quality.

  • Handwritten Documents: Limited performance — more manual review may be needed, though OCR improvements are ongoing.

  • Excel Documents: Not currently supported — support for Excel-based documents is on the roadmap. Stay tuned for updates.
