What is UpSynth? UpSynth is a browser-based AI image editor focused on controlled upscaling, restoration, and selective modification. Instead of guessing what a user wants, it lets them decide exactly how much the AI is allowed to change an image, from subtle clean-up through to more imaginative enhancement. Old photos, movie posters, illustrations, and digital artwork can be repaired, sharpened, and reworked in a single interface that combines three AI tools: Upscale, Restore, and Modify. Key Features: AI Upscale: Intelligently enlarges images while preserving overall appearance. UpSynth analyzes the source, reconstructs missing details, and reduces artifacts or noise so results stay close to the original character instead of looking overly synthetic. Selective Restore: Targets problem areas such as distorted faces, damaged regions, or overcooked AI details. Users brush over a region and UpSynth rebuilds it using the original as a reference, keeping creative freedom to a minimum where accuracy matters. Prompt-Based Modify: Lets users mark an area and describe, in plain language, what should change. This supports object replacement, cleanup, and stylistic tweaks without regenerating the entire frame, and returns multiple variants to choose from. Magic Creativity Control: A “magic” slider determines how conservative or imaginative the AI can be.
