StructiFi

StructiFi costs nothing to use, though the beta caps uploads at 3 MB per file. It is an AI OCR and data extraction tool that turns unstructured documents into structured data you can analyze.

You can feed StructiFi images, PDFs and Word documents, and it also reads handwriting, which many free OCR tools skip.

You give it a file and a list of fields, and it pulls those values out into a structured format.

Accuracy depends on two things: the quality of the file you upload and how well the field list is written.

A blurry scan or a vague field name will give you weaker results, so it pays to test with a few typical documents first.

The 3 MB limit is the main catch.

Large multi-page PDFs or high-resolution photos may need compressing or splitting before upload.

The site also needs JavaScript enabled to run.

For small, occasional extraction jobs, a free tool like StructiFi is a low-risk place to start.
