Chat Us

Pure instant messaging — simple, fast, secure, and synced across all your devices.

FAST:Chat Us is the fastest messaging app on the market, connecting people via a unique, distributed network of data centers around the globe.

SYNCED: You can access your messages from all your devices at once. Start typing on your phone and finish the message from your tablet or laptop. Never lose your data again.

UNLIMITED: You can send media and files, without any limits on their type and size. Your entire chat history will require no disk space on your device, and will be securely stored in the Chat Us cloud for as long as you need it.

SECURE: Chat Us made it our mission to provide the best security combined with ease of use. Everything on Chat Us, including chats, groups, media, etc. is encrypted using a combination of 256-bit symmetric AES encryption, 2048-bit RSA encryption, and Diffie–Hellman secure key exchange.

POWERFUL: You can create group chats for up to 5,000 members, share large videos, documents of any type (.DOC, .MP3, .ZIP, etc.), and even set up bots for specific tasks. It's the perfect tool for hosting online communities and coordinating teamwork.

RELIABLE: Built to deliver your messages in the minimum bytes possible, Chat Us is the most reliable messaging system ever made. It works even on the weakest mobile connections.

FUN: Chat Us has powerful photo and video editing tools and an open sticker/GIF platform to cater to all your expressive needs.

SIMPLE: While providing an unprecedented array of features, we are taking great care to keep the interface clean. With its minimalist design, Chat Us is lean and easy to use.

100% FREE : Chat Us is free and will always be free or introduce subscription fees.

PRIVATE: Chat Us take your privacy seriously and will never give third parties access to your data.

For those interested in maximum privacy, Chat Us offers Secret Chats. Secret Chat messages can be programmed to self-destruct automatically from both participating devices. This way you can send all types of disappearing content — messages, photos, videos, and even files. Secret Chats use end-to-end encryption to ensure that a message can only be read by its intended recipient.

Chat Us keep expanding the boundaries of what you can do with a messaging app. Don’t wait years for older messengers to catch up with Chat Us — join the revolution today.
