What’s up AI transcribes, translates, and summarizes voice and text messages directly within messaging apps like WhatsApp: press and hold a voice message, and the app returns a transcript, translation, or summary depending on what’s needed, supporting English, German, Spanish, Italian, Dutch, Portuguese, Russian, Chinese, Japanese, Korean, and more.
Summarizing a long voice message, not just transcribing it word for word, is the feature that actually saves time – a two-minute rambling voice note transcribed in full is still a two-minute read, while a summary gets the gist in a few seconds, and having the choice between transcript, translation, and summary depending on the situation gives real flexibility a single fixed output format wouldn’t. Working directly inside the messaging app itself, via a press-and-hold action, also avoids the friction of copying message content into a separate translation or transcription tool.
What’s up AI is iPhone-only, free with in-app purchases for a Pro membership tier, at 8.3MB. It’s developed by Christoph Doeffinger and rated for ages 4 and up.
