Focus on the business requirements, not the SMS backend. Outside Agent provides the phone number, conversation memory, database state, action layer, and human handoff system your AI agent needs to work with real customers.

Balloon store quote workflow

An AI agent gathers the customer's event details, creates visual options, and prepares a draft quote for the shop owner to approve.

Floral proposal workflow

An AI agent turns visual taste, event details, and budget pressure into a proposal-ready packet for a florist to review.

Custom cake quote workflow

An AI agent turns a cake photo or description into concept options, estimate ranges, capacity checks, and a review packet for the baker.

Youth program enrollment workflow

An AI agent follows up with parent leads, routes them by campaign, handles common objections, and gives staff a clean enrollment summary.

SMS coaching product workflow

An AI agent turns public-domain Stoic texts into a short SMS coaching experience with memory, accountability, and safety boundaries.

Wedding RSVP workflow

An AI agent texts non-responding guests, collects RSVP details, enforces invitation rules, and escalates edge cases to the planner.

Guest concierge workflow

An AI concierge answers approved event logistics and packages special requests so planners only step in where judgment is needed.

Consultation intake workflow

An AI agent collects aesthetic goals and scheduling context while routing all medical decisions to licensed staff.

Real estate follow-up workflow

An AI agent follows up with open-house visitors, answers approved property questions, qualifies buyer intent, and alerts the agent.

Legal intake workflow

An AI intake assistant collects matter context, detects urgency, gathers conflict-check fields, and avoids giving legal advice.

SMS-first assistant workflow

An AI agent makes everyday help available through normal SMS for people who do not use smartphones, apps, or web chat.

Talk to Maya

Maya is a real agent on the real runtime, running in demo mode — her outward actions are safely simulated. Rate-limited; conversations reset on reload.

No SDKs, no keys, no dashboard wrangling. Connect the coding agent you already use and build from there.

Paste it into your coding agent

Your editor picks up the Outside Agent builder tools over MCP. Sign in once when the browser opens.
