I'm building a PDF generation service (DocSpring), so it's probably time to look into using AI to detect fields on uploaded PDFs so that it's easy to create PDF templates. That's been in my backlog for years. It was probably easy to build this many years ago, but maybe it's even easier now with the latest AI libraries and services.<p>I should really start to get familiar with AI and learn how to use things like PyTorch. I'm a bit nervous though, because it feels very different to all the programming that I've been doing for over a decade. I'm using to building CRUD web apps and mobile apps, writing SQL queries, setting up servers on AWS, etc. I'm not very good at math and I don't really understand how neural networks work or which kind of algorithm I should choose, so it feels like learning a whole set of new skills from scratch. But I can probably figure out how to use some off-the-shelf libraries and frameworks and string something together. Maybe this will be my next weekend project.
