02SmartModeler - Visual Workflow Builder
Build and run QGIS Processing workflows on a visual canvas: start from 21 ready workflows, open your own models in one click, run a workflow on every layer at once and save it as .model3 or Python.
02SmartModeler is a visual canvas for building Processing workflows without writing code. The start page offers 21 ready workflows (everyday tasks such as dissolve, points in polygons, nearest-feature distance, zonal raster statistics and repair-and-reproject, small building blocks, and ten urban-analytics showcases), together with the models in your QGIS profile and your recent files.
Connect tools, use QGIS expressions anywhere, and run the result on one layer or repeat it over every layer you tick, with the outputs collected in one group. Workflows save as native .model3 files for the QGIS Model Designer or as Python scripts.
An optional AI assistant proposes workflows from a plain-language request. It needs your own API key from a supported provider, reads the project without changing it, and nothing it proposes runs until you press Apply or Run. Everything else works without a key.
