24 alternatives to ChatAPI – PWA to Use ChatGPT by API

I've built this PWA to use ChatGPT by API. My main motivation was to use the API since it is much cheaper than the premium plan and I only pay for usage. The main inspiration was ChatGPT-web by Niek [1], but I was lacking time to dig into the code base to make changes. Hence I went for a lightweight approach with Alpine.js and Open Props. There is no build step, the dependencies are fetched via CDN. In general it was much fun to work with Alpine.js - being a parent means having very little time. So it was great to not have to invest 20h into learning a new framework. My main ask was…

ChatAPI is a progressive web app that lets developers use OpenAI's ChatGPT API directly through a browser interface. Built with Alpine.js and Open Props, it requires no build step and loads dependencies via CDN. It's… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    Hi HN, I built this out of frustration of the evergrowing list of AI models and features to try and to fit my workflow. The visual approach clicks for me so i went with it, it provides more freedom and control of the outcome, because predictable results and increased productivity is what I’m after when using conversational AI. The app is packed with features, my most used are prompt library, voice input and text search, narration is useful too. The app is local-first and works right in the browser, no sign up needed and it's absolutely free to try. BYOAK – bring your own API Keys. Let me…

    https://github.com/KTruong008/aichatbestie Been working on this since last week and glad to share it here and now! There's already been a few other takes on this idea, but I figured none would fit me as well as if I had just built it myself. All messages are sent and stored locally in the browser for privacy and speed. Accounts are optional and upgrading is a one-time deal. Any questions, comments, feedback, please, I'd like to hear it all!

    What I thought would take me weeks in development, took me months, but it's finally out. When ChatGPT API came out in March, my first idea of what to build with it was a spotlight-like app for my mac. The product was ready in a matter of days, but making it useful and sellable to people via some kind of distribution platform was another challenge. Coming from web development, learning how to ship a native app was a trip, but here it is, ready to share with the world. Try it out with the free trial, and I'd appreciate any kind of feedback.

    Hi HN, I’m the founder of Pangea. We’ve built a developer platform where you can easily add security to your code through a simple set of APIs - features like authentication, secrets management, audit logging, redaction of PII, restricting embargoed countries, known threat actor intelligence, etc. With the ChatGPT and LLM explosion, we thought of ways to reduce the risk of both the inputs and outputs from these services. Our NextJS sample app adds a security layer on top of ChatGPT with various security services that you can implement quickly. It’s basically a front end to the OpenAI API…
