Viber allows users to send texts, photos, videos, and files. You can also record and send quick voice and instant video messages, making communication more expressive and convenient.Voice and Video Calls
Users can make high-quality voice and video calls, and easily switch between the two during a call. This feature is particularly useful for both personal and professional communications, ensuring clear and reliable connections.Group Chats and Calls
Viber supports group chats and calls, allowing users to communicate with multiple people at once. This includes features like liking and replying to messages in group chats, as well as starting group video or voice calls instantly.Communities
Viber’s Communities feature allows users to join or create large groups with unlimited members. These communities offer more admin control and new conversation features, making them ideal for brands, interest groups, and other large-scale interactions.Stickers and GIFs
Viber provides a vast collection of stickers and GIFs to help users express themselves more creatively. Users can also create their own custom stickers and GIFs to add a personal touch to their conversations.Cross-Platform Compatibility
Viber is available on multiple platforms, including mobile, tablet, and desktop devices. Chats are fully synced across all devices, allowing users to transfer calls and continue conversations seamlessly regardless of the device they are using.Security and Privacy
Viber ensures high levels of security and privacy through end-to-end encryption, meaning only the sender and recipient can access the content of messages and calls. Users can also block unwanted contacts and set specific privacy settings for each individual contact.Viber Out
This feature allows users to make low-cost international calls to any phone number, even if the recipient does not have Viber installed. This is particularly useful for international communications.AI Integration
Viber is ripe for AI integration, particularly through its chatbot API. AI agents can be used to enhance customer support by providing instant, contextual assistance.

AI can also be used for content moderation and personal productivity within the app.Automated Workflows with AI

In summary, Viber combines traditional messaging features with advanced capabilities like AI-driven customer support, cross-platform compatibility, and strong security measures, making it a versatile and reliable communication tool.
Viber - Performance and Accuracy
Performance
Viber has made significant strides in enhancing its performance, particularly in areas such as user acquisition and fraud prevention. For instance, Viber’s collaboration with Adjust’s Fraud Prevention Suite (FPS) has been highly effective. By implementing FPS, Viber was able to protect its marketing campaigns from common fraud schemes, such as simulated or emulated installs and click spamming. This resulted in Viber saving 10% of its marketing budget, which could then be reinvested in acquiring genuine users. In terms of user engagement, Viber statistics indicate strong performance. Users spend an average of 35 minutes on the app per day, sending over 30 messages daily, and launching the app 12 times a day. Additionally, nearly 90% of Viber messages are opened within 3 minutes of receipt, and there are over 70 million interactions on the platform every hour.Accuracy and AI-Driven Features
Viber has introduced AI-driven features to improve user experience and accuracy. The recent launch of the AI summarizer feature is a notable example. This feature helps users manage unread messages in group chats by summarizing key points into digestible bullet points. This tool ensures that summaries are private and do not contain identifiers beyond usernames, and Viber does not store or save these conversations on its servers.Limitations and Areas for Improvement
Despite these advancements, there are some limitations and areas for improvement. One significant concern is the security and encryption of user data. Viber uses a proprietary encryption method, which has raised questions about its strength and openness to independent security assessments. Critics argue that Viber’s centralized encryption scheme, where the company’s servers hold the encryption keys, could be a vulnerability. This setup gives Viber access to users’ private chats, potentially exposing them to security breaches or data requests from authorities. Another area of concern is data privacy. Viber collects user data such as contacts, location data, and device IDs, which, while common among messaging apps, can pose security and privacy risks if not handled carefully.Conclusion
In summary, Viber’s performance is strong, especially in terms of user engagement and fraud prevention. The AI summarizer feature is a valuable addition that enhances user experience. However, there are critical areas that need attention, such as the strength and transparency of its encryption methods and the handling of user data to ensure better security and privacy. Addressing these limitations will be crucial for Viber to maintain and improve its standing in the Communication Tools AI-driven product category.

Viber - Comparison with Competitors
User Base and Global Reach
Viber has a significant user base, with 250 million monthly active users globally, although it lags behind WhatsApp, which boasts over 2.44 billion monthly active users.

Messaging Types and Business Features
Viber offers a variety of messaging types, including promotional, transactional, and conversational messages, which are highly adaptable for different marketing strategies. It also features ‘Broadcast Lists’ and ‘Communities’ for mass messaging and large public groups.
- WhatsApp, on the other hand, uses ‘session messages’ and ‘message templates’ for business accounts, which are more regulated but effective for maintaining customer engagement. WhatsApp also allows proactive selling directly from the app, unlike Viber.
Security and Privacy
Both Viber and WhatsApp use end-to-end encryption, but Viber goes further with features like PIN-protected “Hidden Chats” and “Secret Chats” that self-destruct. This adds an extra layer of security and privacy for Viber users.
Voice and Video Calls
Viber allows voice and video calls within the platform and extends this with ‘Viber Out’, enabling calls to mobile and landlines globally. This is a significant advantage for users needing broader communication options.
Alternatives and Competitors
- WeChat is another competitor that offers similar features to Viber but has a larger user base. It is particularly popular in Asia and allows calls to non-WeChat users at a low cost.
- LINE provides all the features of Viber and also allows low-cost calls to non-LINE users, making it a viable alternative.
- 1-VoIP is a unique competitor that integrates home phone service with smartphone functionality, offering advantages like using the same number for all calls and low-cost international calls.
Cost Efficiency
Viber is generally more cost-efficient compared to WhatsApp, especially for businesses operating in specific regions where Viber has a strong presence.
AI Integration
While Viber itself does not heavily integrate AI tools, other communication platforms and tools can enhance its functionality:
- Otter.ai and Fireflies.ai can be used alongside Viber for real-time transcription services, which can be beneficial for meetings and interviews.
- ChatGPT can aid in generating content, answering customer queries, and automating repetitive communication tasks, which can complement Viber’s messaging capabilities.
In summary, Viber offers unique advantages, particularly in regional and locally targeted marketing strategies, strong security features, and cost efficiency. However, businesses looking for a broader global reach and more integrated business messaging features might find WhatsApp or other alternatives like WeChat or LINE more suitable.
