Translategram is a translation bot that supports over 130 different languages. It also supports inline mode, which means you can translate your messages in any chat. Additionally, it can be added to groups and channels, allowing you to use it in your own groups and channels, helping you write in any language anywhere. Furthermore, you can specify the source and target languages during translation, or simply enter the target language and let the bot automatically detect the source language. These are some of the features that make Translategram the most comprehensive translation bot.
