24 alternatives to Instabooks GPT – Generate textbooks on any subject within ChatGPT

This holiday weekend, I created a GPT for Instabooks, which allows you to instantly generate textbooks on any topic within ChatGPT. Why? ChatGPT is great for learning stuff, but sometimes you just want to go deep and read an entire book about something. For example, there's a great talk by Stephen Wolfram that just goes over my head (https://www.youtube.com/watch?v=fLMZAHyrpyo), so I copy/pasted the transcript into the GPT and it generated a textbook that goes deep into all the topics from that video…

Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Instabooks GPT – Generate textbooks on any subject within ChatGPT launched in 2023; newer entries below may have overtaken it.

    This weekend wanted to try out the streaming ChatGPT API. As test project, created a simple website, which allows you to create whole books by providing just the title (with optional extra instructions). Given the title of the book, table of contents, chapters and sections with text content are generated. All books are listed on the home page, sorted into topic categories. As a bonus, when reading a specific section of a chapter, you can use the chat interface to ask for clarifications, request more content, list relevant topics, etc. The system does quite well with knowledge based books…

    Two of my friends recently welcomed their first child and I "wrote" a kid's book for them using ChatGPT for the story and Midjourney for illustrations. The plot was sourced from a group of friends.

    Hello fellow hackers, we made a site that gets GPT to answer your question using the info on a webpage you specify or document you upload (e.g., a large textbook .pdf file). Background: When ChatGPT came out, I had the idea of having it pull answers from my stereo receiver's annoyingly dense 32 page manual. My weekend project prototype proceeded to surprise with great answers—just like what we've all experienced by now. My co-founder thought we should productize it, and make it easy to use online. So here we are with a very early beta! (Try it on a HN thread...)

    Hi Hacker News! My name is Bea, I built a site called Libraria that uses GPT to do a few things 1. Let you spin up multiple assistants based on your own documents. You can make it public, private, or protected. It has its own subdomain and landing page. 2. Respond in full markdown always, so it can output images, links, code, and more 3. Let you upload articles on the fly within the Chat, so you can ask it questions 4. Make it embeddable in your site with one line of code 5. Let you update it for fun / with your branding 5. Enable syncing for any URLs you let us scrape, so that you can…

    So far I've used it to reference ideas from books I've read before. I've also used it to explore books I have not read before by asking the bot questions. Some people have told me they use it like a reading companion. They pause while reading the book if they have a question, and use Konjer to answer it.
