A room model you can review
Sunlight is spatial.
Sunnook makes it visible.
It models theoretical direct sunlight from the geometry you confirm—so the result is useful for planning a plant, a desk, a reading chair, or an afternoon at home.
Review what matters
Confirm dimensions, window openings, north, date, and location. Sunnook keeps the model inspectable instead of hiding the inputs.
Move through light
Scrub through a day or season to see where clear-sky direct sunlight can reach before rearranging your space.
The same room, a different season
See the year in the shape of light.

- Scrub from morning to evening
- Explore dates throughout the year
- Save favorite spots as Sun Pins
A year of light
