Documind is an open-source tool that turns documents into structured data using AI.

What it does:

- Extracts specific data from PDFs based on your custom schema - Returns clean, structured JSON that's ready to use - Works with just a PDF link + your schema definition

Just run npm install documind to get started.

Multimodal LLM are not the way to do this for a business workflow yet.

In my experience your much better of starting with a Azure Doc Intelligence or AWS Textract to first get the structure of the document (PDF). These tools are incredibly robust and do a great job with most of the common cases you can throw at it. From there you can use an LLM to interrogate and structure the data to your hearts delight.

Do they work for Bills of Lading yet? When I tested a sample of these bills a few years back (2022 I think), the results were not good at all. But I honestly wouldn't be surprised if they'd massively improved lately.

Have not used in on your docs but I can say that it definitely works well with forms and forms with tables like a Bill of Lading. It costs extra but you need to turn on table extract (at least in AWS). You then can get a markdown representation of that page include table, you can of course pull out the table itself but unless its standardized you will need the middleman LLM figuring out the exact data/structure you are looking for.

Huh, interesting. I'll have to try again next time I need to parse stuff like this.
