The request "add-effect" names no product, so the closest matches are products whose indexed actions add an effect to something: Home Assistant can set a custom light effect 16, and Cloudflare Stream-style video tools add audio tracks to video 20. Neither page names an effect-adding action explicitly for general use, so the best fit is Home Assistant for lighting effects; please clarify the target platform.
A question back: What do you want to add an effect to: a light (smart home), a video, an image, or a UI/code element?
