Why Tarsier
Built for the next generation of private, decentralized communication.
Privacy First
Your user ID and private key are generated on-device and stored only there — never on a server.
Decentralized
No single company, server, or person runs the network. Anyone can join and run their own service.
Open Source
Powered by DIM, an open protocol and architecture designed for the next-generation Internet.
Cross-Platform
Message anyone from iOS, Android, Windows, macOS, or right in your web browser.
About
Tarsier is a brand new app focused on secure chat for protecting your privacy. It generates your user ID locally and saves the private key on your device only — not anywhere else.
Imagine a world where you can message anyone without being forced to install the same app. Imagine a world where you can host your own communication and still be part of a huge network. This is brought to you by Tarsier Secure Chat, powered by DIM.
DIM is an open-source project that provides the protocol and system architecture for the next-generation Internet. The DIM network can serve as a social network where users send messages or digital assets freely, and it can also serve the Internet of Things, allowing software to communicate autonomously.
While other platforms are owned and operated by a single corporation with full control, the DIM network is decentralized — there is no one server, company, or person running it. Anyone can join and run their own services on the DIM network.
Service Providers compete by offering better services and a better ecosystem, sharing the same potential user base. Users can choose the provider that fits their needs at any time.
Hope this application brings you more convenience. Enjoy it!
