Arattai, a messaging app developed by Chennai-based Zoho Corporation, is generating buzz as a potential Indian alternative to WhatsApp. The app's name, which translates to "casual chat" in Tamil, reflects its aim to provide a simple and informal chatting experience. While it offers familiar features like one-on-one and group chats, voice and video calls, media sharing, and stories, Arattai distinguishes itself with a focus on data privacy, local data storage, and unique functionalities.
What is Arattai?
Arattai is a free messaging and calling app designed for both personal and business communication. It provides features such as:
- One-on-one and group chats
- Voice and video calls with end-to-end encryption
- Media sharing
- Stories
- Channels
- Multi-device support across mobile, desktop, and Android TV
The app was soft-launched in January 2021, shortly after WhatsApp announced updates to its privacy policy. In September 2025, Arattai experienced a surge in downloads, briefly topping app store charts and surpassing WhatsApp.
Key Differentiators
Several features set Arattai apart from WhatsApp:
- Meetings: Arattai allows users to conduct video meetings within the app, similar to Google Meet or Zoom, with options to create, join, schedule, and view meetings.
- Pocket: This feature provides personal cloud storage within the app for saving messages, media, and other content.
- Mentions: Arattai has a Slack-like "Mentions" section that lists all messages where a user is mentioned, making it easier to track important conversations.
- No Ads: Arattai does not display advertisements and assures users that their data will not be used for advertising.
- Data Sovereignty: All Arattai data is stored in Indian data centers, aligning with the country's digital sovereignty goals.
- Android TV App: Arattai offers an official, dedicated app for Android TV, providing versatility in terms of device accessibility.
- Low Bandwidth Optimization: Arattai is optimized to run smoothly on low-end smartphones and in areas with slower internet speeds.
Privacy and Security
Arattai prioritizes user privacy by pledging not to share user data with third parties. While voice and video calls are end-to-end encrypted, text messages are not yet fully protected. The company says that they are working on adding end-to-end encryption for messages. Arattai stores its data within India, which aligns with Indian data sovereignty laws and gives users more confidence in how their information is handled.
Challenges and Opportunities
Despite its strengths, Arattai faces challenges in competing with WhatsApp:
- Network Effect: Encouraging users to switch from established platforms like WhatsApp can be difficult.
- Encryption Gap: The lack of end-to-end encryption for text messages may concern privacy-conscious users.
- Scaling and Stability: Supporting a large influx of new users without performance issues is a significant technical hurdle.
However, Arattai also has opportunities to grow its user base:
- "Made in India" Appeal: Arattai's identity as a homegrown app resonates with users seeking local alternatives.
- Government Support: Endorsements from Indian government officials boost the app's visibility and credibility.
- Unique Features: Features like Meetings, Pocket, and Mentions offer added convenience and functionality compared to WhatsApp.
- Focus on Accessibility: Optimization for low-end devices and slow networks makes Arattai a practical choice for users with limited connectivity.
The Verdict
Arattai has emerged as a strong contender in the Indian messaging app market. Its focus on privacy, unique features, and support for local needs position it as a viable alternative to WhatsApp. While challenges remain, Arattai's "Made in India" identity and government support could drive further growth and solidify its place in the digital landscape.
