ChatGPT is useful for generating answers to generic questions, but it often responds with inaccurate answers when asked questions about your custom data, document, website, or knowledge base.

One way to try to solve this problem is to copy and paste your data into the chat interface for ChatGPT to use as ‘context’ to answer the question. But you’ll hit a new roadblock: there’s a limit on how much text you can input.

This roadblock is overwhelming and frustrating because the vast majority of valuable data contains much more text than this limit, plus the process of copy-pasting is tedious.

Even if you figure out how to use OpenAI’s api there’s still a lot more to figure out: how to use ChatGPT on various large file formats and data sets? How to split the text to retain meaning and overcome OpenAI’s limits? How to manage costs without breaking the bank? How to optimize prompts to retrieve accurate responses and avoid hallucinations? How to launch a production-ready chat application for users? How to store and manage embeddings? And more.

At this point, It’s easy to give up on building your dream AI chatbot that could save you and your business a significant amount of time and money, and set it apart from competition, but there’s a solution…

Build a MVP for Your AI Chatbot In 2 Weeks

Recently, a new open source tool & framework called LangChain emerged on the AI scene as a solution to this ‘limit’ problem (and many other roadblocks covered in this program).

Whether your data is stored in PDF & CSV files, SQL, a website, APIs or other file formats, LangChain makes the process of building AI applications like a chatbot much easier and quicker to build.

Using a simple tech stack including LangChain, OpenAI, Javascript & Typescript, Next.js, and Vercel, you’ll learn how to create chatbots for documents of any length.

Even if you’re a beginner, by the end of the program you’ll be equipped with a solid foundational knowledge of the current AI capabilities for your work and business, alongside the basic skills and tools to create a simple, well-functioning chatbot application for your custom data.

Enrolled students work for a variety of corporations ranging from leading investment and consulting firms to major educational institutions, including...

You’ll also learn the step-by-step process I used to build…

"I started simple by feeding it a 2022 financial report for one of my clients and asking a few questions about revenue growth and expenses. Certainly made it easy to get answers out of a 120+ page doc."
