    paper SvelteKit AI Chatbot – Fully Featured Chat UI

    This site is a complete AI chatbot interface built with SvelteKit, Tailwind, and shadcn-svelte components, based on Vercel’s AI SDK.

    This site provides a ready-made, production-style chat UI that you can use as a user or copy as a template for your own projects. Visitors can start a new chat, enter questions or prompts, and receive streaming responses from the configured model. Upon logging in, the app saves the chat history, allowing you to revisit previous conversations. Developers can study or fork the GitHub repository and then apply the components and logic to their own Svelte projects.

    Experiment with the chat feature yourself on this site. For persistent logging, try logging in. If you’re interested in the code, you can deploy it with Vercel and reuse the template by following the GitHub link.
