Free Open-Source Artificial Intelligence

I am absolutely new to AI/ML and need some guidance/direction.

Every "New to AI, try this" guide I find ends up going down a path that isn't right for the project I'm working on - or convoluted with so many terms I need to look up, I get rather frustrated. Maybe I'm too old to learn/use AI? Anyway . . .

This is my project, and any guidance, pointers, help would be super appreciated. I'm working on a job aggregator. I have a simple web crawler that goes to a url, fetches the HTML, cleans a lot of the text and structure, and outputs the content of the job posting.

I then go in manually, look at that simplified HTML and extract the actual job description (vs Company description, benefits, other stuff on a job posting) to be used in another database. I use the exact wording, straight copy and paste, no summarization or interpretation.

I have about 400 data points in a database that look like this: job_site: "COMPANY_NAME", raw_html: "Job TitleThis is what we doWe are looking for someone who" job_description: "We are looking for someone who" That I've manually extracted. I feel like I can use that as training data to do some form of text . . . extraction ?? . . . from an html document. But I don't have any clue on where to start
