What's up AI is an app that transcribes and translates voice messages from messenger apps like WhatsApp, Signal, Threema, and Telegram into the user's native language. It uses artificial intelligence and translation technologies to convert spoken messages into text, making it easier for users to understand the information quickly and effortlessly. The app offers a unique summary feature for messages over 500 characters, creating a concise short form of the message. The basic version allows users to translate/summarise one message per day, while the pro version offers unlimited translation/summary of messages.
