What you'll learn
Stop losing charts to the parser
Extract page images alongside text so the visual parts of a PDF stay searchable instead of getting dropped.
Let a vision model read the figures
Have the model describe charts and screenshots so their content becomes retrievable like any other passage.
Answer from the picture, not the caption
Get responses grounded in what a chart actually shows, even when nothing nearby says it in words.
Why this topic matters
A normal PDF parser grabs the text and silently throws away every chart, diagram, and screenshot, which is often where the real information is. In this free 30 minute session you build a pipeline that pulls both the text and the page images out of a PDF, then lets a vision model read the charts so retrieval can use them. You watch a question about a trend line get answered from the picture, not a caption. You leave able to point RAG at real reports and slide decks without losing half the document to the parser.
