🎯 Objectives:

• Bridge Language Barriers: Enable seamless communication between users who speak different languages.
• Enhance User Experience: Provide real-time, automatic translation of messages to improve user satisfaction.
• Expand User Base: Attract and retain non-native speakers by offering language inclusivity.
• Increase Engagement: Encourage more interactions and conversations by removing language constraints.

🔧 Feature:

• The real-time language translation feature will automatically translate incoming and outgoing messages in WhatsApp chats based on the user's preferred language settings. The feature will be optional, allowing users to enable or disable it as needed.
• It will also translate status’ by adding a translate button on the top of the status like we do in Instagram Stories.

⭐️ Proposed Solution:

• Automatic Detection & Translation: Use machine learning(e.g: Meta’s latest llama 3.1) models to detect the language of the incoming message and translate it to the user's preferred language in real-time.
• Manual Translation Option: Allow users to manually translate messages by tapping on them, providing a translation only when requested.
• Language Preferences: Enable users to set their preferred language for translation, including an option to use the phone's system language by default.
• Translation Indicator: Display a small icon or label indicating that the message has been translated and offer a "View Original" option.
• Multi-language Support: Support for a wide range of languages, with regular updates to improve accuracy and add new languages.
