I built CITCAT AI, a colorful personal AI chatbot that lets users manage multiple API configurations and switch between different AI models from one interface. Lately, I’ve been wondering where to host my free API, and that gave me an idea: why not try building a chatbot like ChatGPT? In the demo video, I use PROMPT FORGE (which I also built myself) to generate more detailed prompts.The app includes user authentication, chat history, pinned conversations, message persistence, file and image attachments, API slot management, model selection, Indonesian and English language support, and a responsive chat interface. I built it as a lightweight static web app using HTML, CSS, and JavaScript, The app is deployed on Vercel. What I learned: Designing row-level security policies for user-owned data Managing multiple API configurations Building a responsive chat interface without a frontend framework Deploying a static web app to production Try CITCAT AI and let me know what you think. I created the images and animations using Nano Banana Pro, and you can add them to the prompt later. It might also be a long process, since I have to repeatedly find errors in the AI model and so on. https://citcat-ai.vercel.app/
