About Brieform

Brieform is an AI-native form builder with an MCP server. Create forms, publish them, and read responses straight from Claude, ChatGPT, Cursor, and any MCP client. Built conversation-first. Free. Your AI builds it, publishes it, and reads the responses back, without ever leaving the chat. Responses come in, and you paste them back into your AI one by one to make sense of them. This is the whole workflow: one sentence in, a published form out.

About INT21

We are building self-improving AI systems for the software beneath modern AI. Our first product generates and optimizes low-level GPU software, then proves its work with tests and benchmarks. Today, we are launching INT21: the first company to achieve self-improving AI agent swarms, applied to AI infrastructure. That software has an outsized effect on speed and cost. The first four implementations produced by PTX Kernel Factory are open source today. The product is also entering beta, with early access available at int21.ai.
