Conversational AI you can look in the eye.
Sizzle® builds the conversational AI that replaced chatbots: on-camera, multilingual, in-the-moment, and accountable to your P&L. 311+ engineered brains, 200+ cast faces, 250+ Synth Humans® live and speaking across forty industries in seventy-plus languages. Real-time response. Privacy by architecture. Personality by design.
What “conversational AI” means now.
For a decade, “conversational AI” meant a chat window in the bottom-right of a website that processed a request and shipped a canned answer. Useful for password resets. Useless for the conversations that actually move the business.
Today the term means something different. An on-camera presence that holds a conversation. A persona that knows your business and stays inside its lane. A platform that captures the moment a viewer becomes a customer. Sizzle® ships all three as one system — one architecture, three products, one continuous trust contract from camera to commerce.
The result is conversational AI that runs in retail aisles, hotel lobbies, hospital intake desks, golf courses, civic kiosks, and on every screen between the customer and the brand. It doesn’t replace humans. It holds the conversations no human team can hold — 24/7, in 70+ languages, with the same warmth in every one.
What changed, briefly. Three eras, one conclusion.
The shorthand version. The full comparison — with side-by-side capability tables — lives on the chatbot-comparison page.
The chatbot.
Text in a corner of a webpage. Decision-tree logic. Same answer for every customer. Closed when business hours ended even though the website never did.
- Single channel (text)
- Scripted, brittle responses
- No memory across conversations
- Zero personality, zero brand
- No attribution to outcomes
Generic LLM chat.
A bigger model behind the same text box. Better answers, sometimes. But also: hallucinations, no governance, no brand voice, and no idea whether the conversation made money.
- Still text-only by default
- Eloquent, occasionally inaccurate
- Generic voice, generic persona
- No partner approval on outputs
- Still no attribution layer
Synth Humans®.
On-camera. Cast. Governed. Multilingual. Attributed. A persona that represents your brand, knows your business, stays inside its lane, and produces a P&L line for every conversation that converts.
- On-camera presence, in-language
- Partner-approved knowledge & behavior
- Engineered personality, brand-locked
- Conversation logs auditable end-to-end
- Every conversion attributed to the conversation
One platform. Three jobs.
Conversational AI at Sizzle® isn’t a single product. It’s three engineered layers that ship together. The persona on screen. The compute behind the moment. The commerce layer that makes it accountable.
Synth Humans®.
The on-camera AI persona. Cloud-native, conversationally fluent in 70+ languages, brand-locked, behavior-governed, deployed in days. 311+ engineered brains. 200+ cast faces. 250+ already live and speaking.
- Engineered identity, knowledge, voice, presence
- Partner-approved behavior contract before launch
- Refusal-by-design on out-of-scope topics
- Conversational across 70+ languages live
EdgeBox®.
The on-device intelligence layer. Sensing, inference, and decisioning that runs inside the venue — the moments where cloud round-trips aren’t fast enough, allowed, or prudent. Sub-50ms response. Privacy by architecture.
- On-device inference, sub-50ms response time
- Local-first data handling, partner-configurable
- Continues operating if connectivity drops
- Per-venue privacy policy enforced at the box
Experience Pass®.
The commerce-and-loyalty layer. Every conversation that crosses into action gets captured, attributed, and tracked. Sizzle® earns only when the partner earns — turning the conversation from a marketing line into a P&L line.
- QR-on-screen to Pass-on-phone, no app required
- Per-conversation attribution to redemption
- Partner-visible dashboard on every deployment
- Performance-aligned commercial model
The thesis, verified at scale.
The Sizzle® conversational AI architecture is live at the United Nations COP 16 Climate Accord, on the PGA Tour, across retail brands and hospitality venues. The numbers are not models. They are deployment results.

Conversational AI is a trust contract.
A chatbot in a corner can’t hurt your brand by improvising. An on-camera, in-language Synth Human® in front of your customers can. That asymmetry is why Sizzle® built six trust pillars into the architecture — identity, knowledge, audit, privacy, behavior, partner approval — and a four-phase deployment review every persona runs through before going public.
Every commitment is in writing. Every behavior contract is reviewed and approved by the partner before launch. Every conversation log is auditable. What Sizzle® doesn’t yet certify, it doesn’t claim.
