## 3. Convert PDF Pages to Markdown Using Vision Model
[Learn more about using the Basic LLM node]({{ $env.WEBHOOK_URL }}

Unlike traditional OCR, vision models ("VLMs") "transcribe" what they see so while we shouldn't expect an exact replication of a document, they may perform better making sense of complex document layouts ie. such as with horizontally stacked tables.
 
In this demonstration, we can transcribe our bank statement scans to markdown text for the purpose of further processing. With markdown, we can retain tables or columnar data found in the document. We'll employ two optimisations however as a workaround for token and timeout limits (1) we'll only transcribe one page at a time and (2) we'll shrink the pages just a little just enough to speed up processing but not enough to reduce our required resolution.
