Inspiration
Emails, calendar events, reminders, and messages constantly demand attention, forcing people to monitor systems instead of living their lives. Most tools assume humans should decide what matters and when — which creates noise, stress, and cognitive overload.
We were inspired by a simple idea: attention itself should be managed. Instead of reacting to everything, a personal agent should quietly observe life, stay silent by default, and step in only when something truly deserves attention.
What it does
WhatsApp Personal Assistant is a personal agent that manages actions on a user’s behalf. It connects to everyday tools like calendar and email. When it does, it prepares concrete actions — such as creating events, drafting messages, or setting reminders — and asks for user approval before doing anything irreversible. The primary interface is WhatsApp, able to use in call mode or messaging, so users don’t need to learn a new app or manage dashboards.
