If you're looking for a Glasses Gone alternative, Retouch4me is worth a look. This AI-powered tool comes with a suite of 15 plugins to handle different retouching jobs, like smoothing skin, removing dust specks and correcting color. It can process images locally or in batches, too, so it's a good option for photographers who want to get results as fast as possible.
Another good option is PicWish, an all-purpose AI-powered photo editing service with a range of tools for background removal, face swapping and photo enhancement. It doesn't have a glasses removal option, but its broader range of tools can help you get the look you want out of a portrait photo with less effort.
If you're looking for something more specialized for sprucing up old photos, ImageColorizer has machine learning algorithms to restore and improve photos. It's got tools like AI Retouch and AI Enhance that can upscale faces, remove scratches and otherwise improve portrait photos, so it's a good option for those who want to improve their photos.
Last, Cleanup.pictures is another general-purpose AI-powered image editing service that can remove objects, people, text and other blemishes from photos. It's got more sophisticated inpainting abilities than Glasses Gone, and several pricing levels including a free version, so it's good for both casual and serious users.
