The first project, Emoji Generator, is a good starting point if you want to make your own custom emojis fast and easily. The tool produces emojis in a variety of styles, from cartoonish to photorealistic, so it's good for personalizing your digital communications, like social media posts and chat apps. A single lifetime access price of $29 gets you as many custom emojis as you want.
Another good option is Mirror. The site lets you make custom cartoon emojis and stickers from a selfie. It uses sophisticated face recognition technology and offers a lot of options for clothing, hairstyles and accessories. Mirror supports more than 20 major languages and comes with an emoji keyboard, so it's good for messaging apps, too.
If you want a multilingual and culturally nuanced emoji experience, EMOJIALL is worth a look. It's got support for 47 languages and tools like a sentiment analysis tool, an emoji dictionary and an emoji leaderboard. It also has an emoji maker tool for creating your own custom emojis, so it's a good resource for exploring and creating your own emoji.
