Introducing Langy vs NodePad

Langy is an automated AI engineer inside LangWatch: it reads your traces, writes Scenario tests and evaluations, opens PRs, and proves every fix in your CI.

About Introducing Langy

Langy is an automated AI engineer inside LangWatch: it reads your traces, writes Scenario tests and evaluations, opens PRs, and proves every fix in your CI. It is a full coding agent: it reads your production traces, writes Scenario tests and evaluations against what it finds, connects to your GitHub, opens a pull request on your actual codebase, and proves the change by running the simulations it wrote in your CI. You talk to it where your evaluation results already live, and what comes back is a diff with green checks attached.

About NodePad

Agent on canvas. NodePad lays your AI conversations out on a canvas, so you try more ideas, keep the answers that hold up, and never lose the thread that mattered. You can then use the arrow keys to move the node around. You can then press delete to remove it or escape to cancel. Every message on a NodePad canvas is a node you can build on, and the model only ever sees the context you chose.
