The AI coding app for thinking
Turn rough ideas into clear specs, then stay connected as agents build against them.
How it works
Answer a few questions
Describe what you want to build in a sentence or two. Instead of jumping to code, Nuanced asks about goals, constraints, and what is out of scope, one decision at a time, with a recommended answer for each.

Your answers become a spec
Every decision lands in a living spec with a goal, a summary, and a definition of done. It is the source of truth the agent builds against, and you can edit it directly or point at a section and ask for a change.

Agents build from the spec
Tasks are derived from the spec and the agent works through them while you watch. Every command, file read, and edit is reported as it happens, and you can ask a follow-up mid-run without losing the thread.

The spec stays the source of truth.
