The stack
Five real systems, named.
Text · Anthropic Claude
Claude writes every reply
Rex reads your service menu, hours, and FAQs, then answers or books, in 11 languages. The same model runs SMS, webchat, email, and every DM. No decision tree, no canned replies.
Voice · OpenAI + Grok
Two real-time voice engines, picked per business
OpenAI's gpt-realtime, with ten previewable voices, or xAI's Grok, with five more, chosen per organization. Medical and dental accounts run on OpenAI only: Grok has no HIPAA agreement for call audio.
8 channels
SMS, voice, webchat, email, Instagram, Facebook, TikTok, WhatsApp
Voice answers for every business, no exceptions. Instagram is on by default for med spas, salons, and retail chains. Facebook and TikTok stay off until you connect them.
Booking
Rex books straight into your calendar
RexRuby's own calendar, or a live sync to Boulevard (a full GraphQL integration), Acuity, Jane, Zenoti, Google Calendar, or Cal.com. Vagaro and Mindbody are pending partner approval.
Retention · Ruby
Nine triggers, checked once a day
Lapsed visits (45-day window), no-shows, birthdays, reviews, and referrals run on a daily clock. Reactivated clients come back at 5.4%, against an 0.8% industry baseline. Full breakdown on /ruby.
Agent Studio
Build the voice, then call it.
One screen where you talk or type to Rex, live, in the browser. Change the greeting, the persona, the voice, or what he knows, then call again immediately. It runs the exact configuration a real caller gets.
Security & compliance
Honest about what's done and what's in progress.
10DLC registered, carrier Telnyx
Every number, medical and dental included, is registered with Telnyx before it goes live. No shared shortcodes, no spam-filtered messages.
TCPA opt-in tracked
Consent is logged on every message. Reply STOP and it stops instantly, on every channel.
HIPAA: signed BAA, PHI guard
Medical and dental accounts run under a signed BAA. Outbound messages that look like protected health information are blocked before they send. Full detail on /medical/shield.
Encrypted in transit and at rest
Message and call content is processed by named vendors only: Telnyx for carriage, Anthropic for text, OpenAI and xAI for voice. Nothing beyond that.
SOC 2: audit in progress
The audit is underway. We claim no certification until the report exists.
