What RefineTrain AI does

We rewrite and optimise your internal documentation for AI, giving it deep enterprise context. This unlocks substantially better LLM results across all AI workflows. PROBLEM: -------------- • AI teams struggle with LLM accuracy building AI workflows and agents because of messy, conflicting, fragmented internal knowledge. • Internal knowledge conflicts, uses undefined jargon and rely on unstated company assumptions & context. • LLMs are like Day 0 fresh hires - they can’t understand this documentation properly without someone explaining context to them. • Furthermore, vector search suffers from poorer retrieval accuracy when company context and terms are not present in a knowledge article WHAT WE DO ------------------- • Clean & De-Conflict: Our AI agents read every doc, resolve contradictions, and builds content relationships. • Context Distillation: Our AI agents read & compare related docs, distills context and rewrites an LLM-optimised version of your internal documentation. Optional human-approval ensures 100% confidence in the output. THE OUTCOME ---------------------- • Agents and chatbots that actually understand your enterprise context. • Retrieval that delivers precise, policy-aligned answers on the first try. • A living knowledge base that stays synchronized with every new doc revision.

AI agents rewriting & optimising your internal documentation for LLMs

What is your company going to make? Please describe your product and what it does or will do.

We build AI agents that read, clean, and rewrite internal company documentation so large language models can understand it correctly. Our system resolves conflicts and distills hidden context in enterprise docs, producing versions optimized for AI workflows. This improves LLM accuracy for engineering, product, and design teams using custom AI-driven tools.

Where do you live now, and where would the company be based after YC?

Our team lives in San Francisco and remotely. After YC, we'll remain based in San Francisco with remote flexibility.

Explain your decision regarding location.

San Francisco is a hub for AI and enterprise tech talent, letting us recruit and build relationships with early customers nearby. Remote work lets us keep flexible and tap talent worldwide.
