Overview
Welcome to the comparison between CustomGPT and Langchain!
Here are some unique insights on CustomGPT:
CustomGPT.ai is our own RAG-as-a-Service platform—a way to turn your internal data into a smart assistant without wrestling with infrastructure. Whether you drop in files or point it at a website, it handles the heavy lifting and gives you a clean API (plus a friendly UI) so both developers and business folks can get moving fast.
We built CustomGPT.ai to take the pain out of AI roll-outs: everything works out of the box, yet you can dig deeper whenever you need tighter integrations or special tweaks.

LangChain is a developer library, not a SaaS. It lets you wire up LLMs, retrievers, and tools however you like. That freedom thrills coders but means you’re responsible for every piece of the puzzle.
