Briar - User Interface and Experience
User Interface Overview
The user interface of Briar is crafted with a focus on simplicity, security, and ease of use, particularly for individuals who need a secure and private way to communicate.Initial Setup
When you first open Briar, you are prompted to create a username and password. This is a straightforward process that does not require any personal information, ensuring your anonymity from the outset.Adding Contacts
To add a contact, you share a link with the person you want to connect with, and they do the same. Once both links are added, you can start communicating. This process is peer-to-peer, meaning there is no central server involved.Messaging
The messaging interface is intuitive. You can send private messages by tapping a contact’s name in the contact list. All messages are end-to-end encrypted, ensuring that only the sender and recipient can read them. If your contact is offline, the message will be delivered the next time you are both online.Additional Features
Briar also supports groups and forums, which function similarly to other messaging apps but with enhanced security features. Forums are public rooms where anyone can join and communicate, similar to IRC chats. Additionally, Briar has a blog feature that combines elements of Twitter and blogging, allowing users to post updates that are visible to their contacts.Connectivity Options
One of the standout features of Briar is its ability to function without an internet connection. It can sync messages via Bluetooth, Wi-Fi, or even memory cards, making it highly useful in crisis situations or areas with limited internet access. When the internet is available, Briar uses the Tor network to protect users from surveillance.Customization and Security
The app allows you to customize your experience through settings such as changing the color scheme (light, dark, automatic, or system default). There is also a screen lock feature that protects your privacy by requiring a PIN, pattern, or password to unlock the app, using the same security measures as your device.User Feedback and Onboarding
While Briar is generally easy to use, there have been some user feedback issues regarding the onboarding process. Users have suggested improvements such as clearer documentation, GIFs to explain processes, and contextual help throughout the app. The developers are working on enhancing the user experience by addressing these feedback points.Overall Experience
The overall user experience of Briar is centered around security and privacy. The app is free and open-source, ensuring transparency and trustworthiness. It is particularly beneficial for activists, journalists, and anyone who needs secure communication without relying on centralized servers. Despite some minor issues with onboarding, Briar provides a secure and reliable way to communicate, even in challenging environments. Briar - Key Features and Functionality
Briar: A Secure Messaging App
Briar, as described on the Briar Project website and other sources, is a secure messaging app that prioritizes privacy and decentralization. Here are its main features and how they work:
Decentralized and Peer-to-Peer Messaging
Briar operates without centralized servers, using a peer-to-peer model. This means that messages are directly exchanged between devices, either via Bluetooth, Wi-Fi, or the Tor network. This approach ensures that messages are not stored on any servers, enhancing privacy and security.
End-to-End Encryption
All communications on Briar are end-to-end encrypted by default. This ensures that only the sender and the intended recipient can read the messages, providing a high level of confidentiality and security.
Offline Capability
Briar allows users to communicate even without an internet connection. Messages can be sent via Bluetooth or Wi-Fi to nearby contacts, making it useful in situations where internet access is limited or unavailable.
No Personal Information Required
To use Briar, users do not need to provide any personal information. They can simply choose a username and password, and their account is only accessible on the device they set it up on. If the password is forgotten, the messages and account become inaccessible, adding an extra layer of security.
Message Delivery Mechanism
Messages are stored on the device and periodically retried if the recipient is offline. This ensures that messages are delivered as soon as the recipient comes online, although it may not provide the instant messaging experience users are accustomed to with other apps.
Groups and Forums
Briar supports private groups and forums. Groups function similarly to those in other messaging apps, while forums are public rooms where anyone can share information and communicate with others. This feature allows for community-based discussions and information sharing.
Blogs
Briar also includes a blogging feature, which is a mix of Twitter-like posts and traditional blogging. Posts made through this feature are public to the user’s contacts, allowing for broader sharing of information.
AI Integration
There is no indication that Briar integrates AI in its functionality. The focus of Briar is on providing secure, decentralized, and private communication, without the use of AI technologies.
Conclusion
In summary, Briar is a privacy-focused messaging app that leverages decentralized and peer-to-peer technologies to ensure secure and private communication, without relying on AI. Its features are designed to protect user privacy and maintain communication even in challenging environments.
Briar - Performance and Accuracy
Performance and Accuracy of Briar

Element is more suited for organizations needing flexible and federated communication solutions.
Rocket.Chat
Rocket.Chat is a communications platform that offers real-time conversations but does not have the same level of decentralized, peer-to-peer functionality as Briar. It is more geared towards team communication and does not offer offline capabilities.
BBM Enterprise
BBM Enterprise provides enterprise-grade messaging with end-to-end encryption but relies on centralized servers, unlike Briar’s decentralized approach. It is more focused on business and professional use cases rather than the specific needs of activists, journalists, and civil society groups.
Data Privacy Management Tools
While Briar is primarily a secure messaging app, it’s worth comparing it to broader data privacy management tools that may offer complementary features:
Securiti AI
Securiti AI is a comprehensive data privacy and security platform that automates compliance tasks, such as DSARs and consent management. It uses AI-driven insights for real-time data usage visibility and proactive risk assessment. Unlike Briar, Securiti AI is focused on data governance and protection across large datasets and multiple cloud environments, making it more suitable for businesses with complex data management needs.
DataGrail
DataGrail is another data privacy management platform that offers real-time data mapping, automated DSR management, and privacy risk assessments. It integrates with various third-party tools and supports zero-trust access controls.
