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 Lefts

Lefts is a very simple domain specific language for building complex machine learning workflows from simple ones. Starting with your favourite machine learning models, you can use Lefts operations to:. Without making subsequent model fitting, evaluation or experimentation any more complex than it was with the original model. This implementation is built on top of the excellent Polars DataFrame library. E nsemble: Takes a set of models and makes them evaluate as one. F eed: Allows the output of one model to be used as a feature or target by another.
