Zylch isn't a chatbot. It's a complete AI system built from the ground up for business communication.
While others wrap generic LLMs with thin prompts, we've built proprietary technology that combines the intelligence of modern AI with the reliability your business requires.
LLMs can talk. Zylch can work.
Zylch uses a neurosymbolic architecture—combining neural networks (LLMs) for understanding with symbolic systems (rules, logic) for reliable execution.
Natural language comprehension, intent extraction, context awareness. The AI understands what you want.
Deterministic execution, conditional logic, state tracking. The system does what it promised.
Persistent knowledge about your contacts, preferences, and history. No re-explaining.
Real integrations with email, calendar, phone. Not just suggestions—actual results.
Large Language Models are remarkable at understanding and generating text. But for business work, they have fundamental limitations:
LLMs forget everything between sessions. They can't remember "I told you this yesterday."
They can't track "wait for response, then do X." Every request starts fresh.
Same prompt, different results. You can't build business processes on probabilistic outputs.
They generate text, not results. "Send an email" produces words about emails, not sent emails.
Zylch solves each of these: Our memory system persists knowledge. Our symbolic layer tracks state. Our rule engine guarantees execution. Our integrations take real action.
At the heart of Zylch is our Avatar system—pre-computed intelligence about every person you interact with.
Unlike systems that re-analyze contacts on every query (slow, expensive), Avatars are continuously updated in the background. When you ask "What's happening with Marco?", the answer is instant.
One person = multiple emails, phones, names. Avatars understand identity across all channels.
Preferred channel, tone, response patterns, pending items, relationship strength—all pre-computed.
New email arrives? Avatar updates automatically. Always fresh, never stale.
Avatars know who needs attention, who's waiting for response, who's going silent.
Many "AI products" are thin layers over ChatGPT or Claude. Zylch is different.
Hahn Banach founded. Initial research into semantic memory systems for business applications.
First production deployment of vector-based contact memory. Pre-dates ChatGPT release.
Multi-agent architecture developed. Neurosymbolic execution framework.
Avatar system architecture. Background computation pipeline. Legacy system integration.
Zylch platform launch. Phone integration via MrCall. Production deployment.
Years of R&D, not weeks. Our technology stack is proprietary, purpose-built for communication intelligence.
We take privacy seriously because we handle your most sensitive data: your communication.
Your data is never mixed with other users. Row-level security enforced at the database layer.
Your emails, contacts, and conversations are never used to train AI models. Ever.
All data encrypted at rest and in transit. Sensitive tokens encrypted with additional application-level encryption.
Critical actions (sending emails, making calls) require your explicit approval.
