Анонимный чат Ктотут is a free chatting app developed by Room lab for Android users. This app allows users to chat with new people one-on-one without the need for registration or SMS. The app boasts of its privacy feature, as it does not require the user's phone number, email, or any other personal data.

The chat is divided into two rooms: Green for communication and Krasanya for flirting (18+). Users can exchange photos, send gifs, draw sketches, and do all of these without any cost or registration. Анонимный чат Ктотут features automatic moderation to ensure order in the chat, and a complaint system where users can report violators of the rules. The app also uses a unique neural network that filters out inappropriate photos in the Green room.

The app has several features that make chatting more convenient, such as choosing the user's preferred gender, sending photos and gifs, drawing in the chat, using codes to reconnect with a previous conversation partner, and a dark theme. Анонимный чат Ктотут promises that it does not store or share any user information with third parties.
