Muse

What it does

Muse is the personal AI agent that does things instead of just talking about them: triage your inbox, research a purchase, schedule the appointment, handle the shopping. It's the "errand-running" vision of AI — less chatbot, more chief of staff. Built by Meta, living where your life already happens.

Pricing that matters

The free tier is the story: around 100 million tokens a week free, per Zuckerberg himself — a free tier this generous doesn't exist anywhere else in AI agents. The fine print: signing up requires a payment card (purchasing is a core feature) and being 18+ in the US or Canada, since it's US-locked. Paid tiers are priced like everyone else's, but for most normal humans doing normal chores, free is plenty. Pricing is press-reported — treat exact token math with a grain of salt. As of Oct 2026.

Best for

Anyone who wants an AI that runs errands instead of just chatting. Inbox triage, research briefs, scheduling, shopping — the chores, handled.

The honest take

The free tier undercuts the entire category — rival agents start around $20 a month with no free tier at all. The catches: US/Canada only, no Windows app, and nobody outside Meta can say exactly what a "Muse token" maps to (heavy browser jobs burn faster than chatting). It's either generosity or a land grab, depending on how cynical you're feeling today. Either way, the price is right.
