DobbieAI: ChatGPT on Multiple PDFs at Once

I just built a tool to chat with multiple PDFs and websites at once. Here's the link: https://dobbieai.com

Some features include:

1. create a knowledge base, choose a model GPT3.5 / GPT4, 2. add one ore more files to the knowledge base, 3. ask questions where the answer might be spread across files

Here are 2 demo videos:

Demo 1: Chat with 4 books at once.

Founders at Work by Jessica Livingston, The Lean Startup by Eric Ries Zero to One by Peter Thiel Make Something Wonderful - Steve Jobs

Demo 2: Chat with NVIDIA's earnings reports https://www.loom.com/share/92c17743143045099d328181462f714f

Would love to hear what you think and if you find it useful! There might be few bugs that I might have missed, so please feel free to report them. :)
