Recommended workflow

  1. Use OCR to turn pixels into characters.
  2. Use structured extraction to turn characters into fields, tables, and business data.
  3. Use a reading assistant to find and synthesize information with evidence.

Good practices that reduce errors

  • Measure quality on your own document types.
  • Route uncertain fields to human review.
  • Do not use unverified output for high-risk decisions.

How to evaluate the result

Do not stop at confirming that a file downloaded. Compare page count, reading order, names, numbers, tables, fonts, and whether the result opens on the recipient's device. Legal, financial, or personal data requires human review before release.

Why use one connected platform?

When conversion, organization, security, and AI live in one ecosystem, users can continue to the next step without sending documents through unrelated services. Built by RBTtech, ChuyenFile focuses on browser-based document workflows with tool-specific guidance and support for Vietnamese, English, and Chinese content.

Bottom line

Begin with a non-sensitive sample, validate the result, and then standardize the workflow for the team. This is more reliable than assuming one setting works for every document type.
