Are you eager to build ChatGPT Apps? I heard OpenAI released an Apps SDK without the SDK... :sweat_smile: We were really excited to use it, so we built an SDK for Apps SDK. Check it out and give us a github star if you like it

    I went swimming in the ocean of OpenAI's Apps SDK… and came back with a handbook! Over the past few weeks, I’ve been diving deep into the ChatGPT App SDK: exploring its APIs, tools, and hidden gems. Along the way, I built, broke, fixed, and reimagined a bunch of little experiments. P.S: Indeed OAIs official docs is the source of truth, this is just a rough notebook Maybe, I can create a CLI tool to scaffold app?

    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…

    Hey everyone, We have been building SecureAI Tools -- an open-source application layer for ChatGPT and ChatPDF-like AI tools. It works with locally running LLMs as well as with OpenAI-compatible APIs. For local LLMs, it supports Ollama which supports all the gguf/ggml models. Currently, it has two features: Chat-with-LLM, and Chat-with-PDFs. It is optimized for self-hosting use cases and comes with basic user management features. Here are some quick demos: * Chat with documents using OpenAI's GPT3.5 model: https://www.youtube.com/watch?v=Br2D3G9O47s * Chat with documents…

    Hi HN! Two weeks ago at their Dev Days, OpenAI unveiled ChatGPT apps, interactive widgets that render inside ChatGPT using the Apps SDK and MCP. Building them using their template repository was surprisingly painful: every time you make a change on your React widget, you need to rerun the entire build pipeline to get fresh JS and CSS assets. The dev feedback loop was pretty terrible. That’s why I built a TypeScript starter that gets you up and running in under a minute. Clone, npm install, npm run dev, paste your ngrok URL into ChatGPT, and you're iterating on widgets with Hot Module Reload…

    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.
