I built an open source website that lets you upload large files such as academic PDFs or books and ask ChatGPT questions based on your custom knowledge base. So far, I've tried it with long ebooks like Plato's Republic, old letters, and random academic PDFs, and it works shockingly well.

    OP Vault ChatGPT: Give ChatGPT long-term memory using the OP Stack (OpenAI + Pinecone Vector Database). Upload your own custom knowledge base files (PDF, txt, epub, etc) using a simple React frontend.

    I deployed the code here if you want to play around with it: https://vault.pash.city. Feel free to upload any non-sensitive or non-personal documents and experiment with the site. That being said, I strongly recommend you run the code locally and use it at your own pace with no size/length limitations (though be careful with your OpenAI API usage!)

    Hey thanks for creating this, will try later if i have time. Meanwhile, do you try some of other second brain app such as this, and how was the comparison? The one i mentioned was trending on github so i think its decent (been playing with it since last week or so, also). But i already starred your repo so i can come back later.

  • I built an open source website that lets you upload large files, such as in-depth novels/ebooks or academic papers, and ask GPT4 questions based on your specific knowledge base. So far, I've tested it with long books like the Odyssey and random research PDFs, and I'm shocked at how incisive it is.
