Who we are
A company built on preserving context in a world of fragmented data.
LLM Prep is a document processing platform built for the age of AI. We help developers and businesses turn their messy documents into clean, structured data that Large Language Models can actually understand.
Why We Built This
LLMs are only as good as the data they're fed. Poorly formatted documents, inconsistent structure, and messy conversions lead to hallucinations and unreliable AI responses. We created LLM Prep to solve the "garbage in, garbage out" problem—ensuring your documents are clean, structured, and ready for AI consumption from the start.
Traditional document conversion tools weren't designed with modern AI systems in mind. We built LLM Prep specifically for small business owners and developers building RAG applications, with features like semantic chunking and structure preservation that make a real difference in AI performance.
Our Commitment
Privacy First
Your documents are processed in memory and immediately deleted after conversion. We never store, log, or retain your files. What you upload stays private and is permanently removed from our servers after 24 hours.
Transparent Pricing
Pay only for what you use. No subscriptions, no hidden fees. Credits never expire. Start with 3 free credits per day, then purchase packs as needed.
Quality Output
Every conversion is optimized for LLM consumption, maintaining structure and context while removing formatting noise. Our process ensures your documents work better with AI systems.
