Can't recommend PDF Vector enough! It boosts your AI workflow accuracy to 100% while dropping your costs! Especially if you're a T4 Org in the $150/m spend range!

Gotta give a shoutout to PDF Vector team for helping me set up PDF Vector for a project. They even delivered on a feature request before I purchased. Incredible customer service. 👏

Been implementing RAG and changing a lot of things under the hood for @rabbitholesai, came across PDF Vector and it was a huge time saver. I got a document parsing solution for the rag pipeline within minutes! one less thing to worry about
