Sliders are a good way to control continuous AI parameters across many different applications. In photo editing apps like Lensa AI, sliders control parameters such as "Face retouch," "Deep retouch," "Neck retouch," and "Eye bags" adjustments. In text generation, sliders might control verbosity or creativity. In voice AI, they might adjust the speaking rate or accent strength. Unlike on/off toggles or radio buttons, sliders allow for fine adjustments along a range.

When designing sliders for AI control, clearly label what the slider adjusts and what each end of the range means. For example, a face retouch slider might show a minimal value on the left and maximum on the right, with numbers (like 0-1) to indicate intensity. This helps users understand how moving the slider will affect the results. For less intuitive parameters, showing visual examples of how different slider positions change the output helps users make better choices.

Consider whether the slider should have specific steps or be completely smooth. Steps work well when there are meaningful thresholds or when users might want to reproduce exact settings later. Smooth sliders offer more precise control but make exact reproduction harder. Also, consider whether to show numerical values next to sliders, as seen in the Lensa AI example, where "1" indicates the current intensity level. These numbers help with precision but add visual complexity.
