Sim: Build AI Agents on a Visual Canvas

The story

What the video said

Sim is an open source app that turns your idea for an AI agent into a working workflow you can run and watch. You build it on a canvas, then use it as a chat, an API, a schedule, or a webhook.

You want an AI agent that reads your files and answers questions, but wiring the model, the data, and the tools together by hand takes days. You need a place to see the whole flow and fix it fast.

Sim is an open source workspace for building, deploying, and monitoring AI agents and workflows. It gives you a visual canvas, a chat surface, and hundreds of blocks for tools like Slack, Notion, and databases.

In the files demo, you type a prompt asking for a summary, pick a file, and Sim builds a sales pipeline document with a table of deal totals and a source citation. You can see the agent work step by step.

The reason to care is simple. Sim is free and open source, so you can run it on your own machine and keep your data close. Would you use this workflow for your own agents?
