From reactive to proactive support

Most AI assistants wait for you to ask. They’re reactive: you message, they respond. But the real power of an always-on assistant is doing things before you ask.

Reminders, planning, follow-ups, and cross-app actions—all from a single assistant that runs continuously in the cloud.

Powerful agent runtimes

Ara runs on ZeroClaw, a fast AI agent framework built in Rust. ZeroClaw manages conversations, tools, memory, and channel bridging. It’s not a thin wrapper around an API—it’s a full agent runtime that decides when to act.

For lighter workloads, NanoClaw offers a smaller footprint. Both runtimes support 30+ AI providers and 14 messaging channels, so your assistant can operate across WhatsApp, Signal, Telegram, iMessage, and more.

Proactive in practice

With the right configuration, your assistant can remind you to call someone, follow up on an email, or plan your week—all without you having to prompt it each time.

The key is giving the assistant a clear mission, sensible autonomy limits, and access to the tools it needs. Then it can run reminders, planning, follow-ups, and cross-app actions from a single, always-on session.
