🤔 Why PDF Eater?

Most people find AI assistants like ChatGPT or Claude incredibly useful for everyday tasks. But when it comes to specialized domains — medical reports, legal documents, academic papers, technical manuals — things start to fall apart:

• 🤥 AI hallucinates. It confidently gives you wrong answers when it doesn't know something.
• 🎯 AI goes off-topic. It answers questions you didn't ask, based on its general training data rather than your specific document.
• 🔍 AI lacks precision. It can't reliably point you to the exact passage, clause, or data point you're looking for.

On top of that, keeping up with a ChatGPT or Claude subscription gets expensive. And if you're calling APIs directly, the costs add up even faster.

The truth is, most people don't need a general-purpose AI assistant for document work. They just need something that can read their PDF and answer questions about it accurately — using a cheap, fast model.

That's exactly what PDF Eater does. 🍽️
