Project mention: Show HN: Documind – Open-source AI tool to turn documents into structured data | news.ycombinator.com | 2024-11-18
From the source, Documind appears to:
1) Install tools like Ghostscript, GraphicsMagick, and LibreOffice with a JS script. 2) Convert document pages to Base64 PNGs and send them to OpenAI for data extraction. 3) Use Supabase for unclear reasons.
Some issues with this approach:
* OpenAI may retain and use your data for training, raising privacy concerns [1].
* Dependencies should be managed with Docker or package managers like Nix or Pixi, which are more robust. Example: a tool like Parsr [2] provides a Dockerized pdf-to-json solution, complete with OCR support and an HTTP api.
* GPT-4 vision seems like a costly, error-prone, and unreliable solution, not really suited for extracting data from sensitive docs like invoices, without review.
* Traditional methods (PDF parsers with OCR support) are cheaper, more reliable, and avoid retention risks for this particular use case. Although these tools do require some plumbing... probably LLMs can really help with that!
While there are plenty of tools for structured data extraction, I think there’s still room for a streamlined, all-in-one solution. This gap likely explains the abundance of closed-source commercial options tackling this very challenge.

>web dev/gradle/java knowledge to build something like this
Web dev (and not just in java) is dominated by "component integration" concerns, containing lots of structure but little content. Computation is delegated to libraries, and the problems more about complexity of integration (at build time) scaled distributed systems (at runtime). In contrast, writing a simulation is computationally intensive, so most of the code is content. It's homogenous where web dev is heterogenous. The problems are entirely constrained by single process performance within a time budget determined by fps.
All that means is that you can focus on one runtime. I suggest the browser, since it solves the distribution problem. Ganja[1] is perhaps the ultimate "content, not structure" simulation project. It's very strange, and lies unmaintained because it's impenetrable. Yet it works. A bit more structured is D3 who's authors have written cutting edge visulation/layout algorithms for you, for example in support of force directed graphs[2]. A more friendly way to get started would be with some variant of Processing[3], which started as a Java thing and then got ported around, including to Python and JavaScript. A word of warning: something like cloth simulation is to a game engine what a single cell is to a mouse. Game engines are huge, in other words, and again you won't be writing simulations, lots of (internal) integrations.
