Simple AI

Overview

simple-ai is an open-source registry of agent examples by Alwurts, inspired by shadcn/ui. Its stated goal is "curated agent examples you can build upon": developers copy the code into their app and change the source. It is organized in three levels: components are pieces, blocks are a whole screen and templates are a whole app.

The first block is a chat page that shows the thread, the prompt, tool calls and model thinking, with the agent's work folded away so the answer stays readable. The Starter template is a full app with sign-in, an organization setup step and an agent chat. The MIT-licensed source is on GitHub at Alwurts/simple-ai.

Features

• Chat page block: Thread, prompt, tools and reasoning in one screen, added with a single CLI command
• Chat input: A prompt input built on Tiptap with @mentions
• Tool display: Shows what the agent called, with input and output JSON
• Worked summary: Collapses the agent's steps ("Worked for 4s") behind the final answer
• Reasoning component: Renders model thinking alongside the response
• Starter template: An app where people sign in, name their organization and talk to an agent
• AI SDK based: Components use the Vercel AI SDK and Streamdown for streaming output

Tech stack
