Mirrors vs NodePad

Mirrors rebuilds the systems your AI agents call and replays real sessions against every prompt, tool, or model change before it reaches production.

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.

About Mirrors

Mirrors rebuilds the systems your AI agents call and replays real sessions against every prompt, tool, or model change before it reaches production. Schema, seed data, and tool behavior mined into a runnable copy of the systems your agent calls, including the internal tools nobody will give you a test instance of. Every change is tested against past sessions before it merges. The Replay screen diffs each recorded production call against its counterpart in the environment, so you can see where the two agree and where they drift before you trust it with a merge gate.

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.
