Feryn

Feryn is an AI personal assistant that lives inside your messenger — Telegram, WhatsApp, Signal, or Messenger — so you can track daily life through chat instead of a separate app. From within a conversation you can snap a receipt to log an expense, say what you ate to record a meal, log a workout, and track a shared family budget, then receive a morning digest that summarizes it back to you. Because it runs in messaging apps you already use, there is no new interface to learn; you interact by sending messages and photos. A defining feature is its data model: your information is stored in your own Google Drive, and Feryn keeps no persistent copy on its servers, so you retain ownership of your logged data. This suits people who want a lightweight way to track expenses, meals, workouts, and a household budget without installing and switching to a dedicated finance or fitness app, and who care about keeping their personal data under their own control. It is best for individuals and families who want to log spending, food, and fitness through chat while keeping the data in their own Google Drive.
