PyxiGrow

PyxiGrow is a creative drawing app where your strokes become growing organic patterns. Build intricate textures, branching networks and colourful compositions, combining your own ideas with the surprising behaviour of nature-inspired simulations. Developed by scientists, PyxiGrow uses advanced mathematical models to grow its patterns. Growth is calculated on your device without AI image generation. You choose where it begins, shape its behaviour and decide how it becomes part of your artwork. No scientific background is needed. Choose a model family and start with a built-in DNA preset. With Tune DNA, you can adjust model parameters to change how a pattern develops. Experiment with the available controls, create your own variations of its digital genome and save your favourite DNA presets for future projects. Sketch shapes with Brush, add colour with Fill and refine them with Erase. Then use Let it Grow to turn painted areas into starting points for organic growth. Explore different colours and patterns, and combine hand-drawn marks with evolving structures. Create and save projects, organise your artwork into layers and return to it whenever inspiration strikes. Keep elements separate, combine different patterns and develop an idea one layer at a time. Export your artwork as a PNG with a canvas background or transparency, ready for sharing, printing or use in other creative projects. Your creations are yours to use: publish them, share them or use them commercially. PyxiGrow does not claim ownership of your artwork. The free version includes Lichen, Mold, Physarum and Neurons, up to two drawing layers plus a background, selected Tune DNA controls and one saved custom DNA preset per model family. Your first three successful exports are watermark-free. Later free exports include a watermark. Premium adds all eight model families, all Tune DNA controls, up to nine drawing layers plus a background, unlimited saved custom DNA presets, watermark-free exports and the option to finish growth instantly when switching models or tools. Colour customisation and Let it Grow settings are available in both versions. by scientists - for everyone. Follow your curiosity and see what grows.
