Affinity offers on-device machine learning tools in Affinity Photo (version 2.6, released February 2025) that automatically detect and select objects or the primary subject within an image, helping designers make complex selections faster.

The Object Selection Tool uses a segmentation machine learning model to identify and highlight individual objects in a photo when the user hovers over them. The Select Subject feature uses a saliency machine learning model to automatically identify the most prominent subject in the scene. Both models are optional, must be downloaded by the user, run entirely on-device (no data leaves the user's device), and are pre-trained — they do not use user data for further training. The features require Apple Silicon Macs running macOS Ventura or later, or Windows x64/ARM64 hardware running Windows 10 or 11.
