Most AI assistants forget everything the moment a conversation ends. Zylch is different.
We're building an AI that constructs a deep memory of you, your relationships, and your working style. Not just a database of facts, but a semantic understanding that grows smarter with every interaction.
The result? An assistant that truly knows you. One that remembers Marco prefers formal emails, that Sofia always responds faster on WhatsApp, that your Tuesday mornings are sacred.
Traditional search finds exact matches. Zylch understands meaning.
Not keyword matching. Semantic understanding. "Draft email to Marco about invoice" finds similar patterns even if you've never written those exact words.
Hierarchical Navigable Small World graphs. O(log n) search complexity. Millisecond retrieval even with millions of patterns.
Like a highway system: start with long-distance links, then refine locally. 117x faster than linear search.
Every pattern has a confidence score. Approved actions gain trust. Rejected ones lose weight. The system learns what works for you.
Your memory is yours alone. Complete isolation by design.
Multi-tenant architecture. Your patterns, preferences, and history are completely separated from other users.
Personal memory for your style. Global knowledge for best practices. Your preferences always take priority.
Approve a draft? Confidence increases. Reject it? Confidence drops. Every interaction makes the system smarter.
Patterns unused for 90+ days gradually lose relevance. Your memory stays fresh and current.
Not one AI doing everything. A team of specialists collaborating through shared memory.
Understands urgency, sentiment, and relationships in every message
Writes in your voice, matching tone to each relationship
Manages calendar, follow-ups, and commitments
Enriches unknown contacts with relevant context
Handles calls with context-aware scripts
Orchestrates agents and routes tasks to the right specialist
Shared Memory Protocol: Agents don't talk to each other directly. They communicate through memory. What one agent learns, all agents can use.
Security isn't an afterthought. It's built into every layer of the architecture.
Every decision is logged. You can always ask "why did you do this?" and get a clear answer.
Critical actions always require your approval. Zylch suggests, you decide.
Dedicated agents monitor behavior, detect anomalies, and ensure quality.
Your memory is never used for training or shared with other users. Period.
Advanced intelligence that goes deeper than surface-level analysis.
Not just syntax analysis. We check SPF, DKIM, DMARC records to identify spoofed or suspicious emails.
Identifies AI-generated emails through comprehensive analysis, not just stylistic patterns.
Understands connections between people and companies. Who works where, who knows whom.
Monitors how relationships evolve over time. Catches cooling relationships before they go cold.
Gap Detection: Automatically identifies relationships that need attention. "You haven't heard from David in 3 weeks. Last time, he responded within a day."
Your relationships don't live in just one place. Neither does Zylch.
One view of every interaction. Email threads, calls, messages - all in context.
Formal on email, casual on WhatsApp. Same contact, different rules per channel.
Cross-Channel Intelligence: "Sofia responded on WhatsApp after ignoring 3 emails. She prefers short messages."
Not robotic scripts. Natural conversation with real understanding.
Advanced text-to-speech that sounds human, not mechanical.
Speech-to-text with contextual comprehension. Understands intent, not just words.
Calls adapt to responses. No rigid scripts. Real dialogue.
Knows who's calling before answering. Adapts behavior based on relationship history.
Call Summary: Automatic transcription and key points after every call. Nothing gets lost.
Enterprise-grade performance, even as your data grows.
Known patterns are retrieved locally. Instant responses for familiar requests.
Embeddings and results are cached. No redundant computation.
All this technology exists for one purpose: to make you more effective. Not to replace you. To amplify you.
