The platform

Two layers that turn context into action.

Sylvie is built as two layers that build on each other: a living memory of every brand, and an agent runtime that executes on top of it. The home tells you what Sylvie does; this is how it's actually built.

How the memory works

Not a pile of documents. A structured, living model.

Sylvie turns the scattered signals from your stack into structured memory: facts, approvals, rules and relationships, isolated per brand and traceable to their source.

  • Captured at the source. Read directly from the tools where decisions happen, no manual entry.
  • Precedence-aware. Newer decisions override older ones, so the brain never contradicts itself.
  • Always cited. Every fact traces back to the message, file or campaign it came from.

How agents run

Agents that execute, on the memory beneath them.

Because the agents sit on the brain, they never start from a blank page, and they finish the job inside Sylvie, never handing your team off to another tool.

  • Read the brain first. An agent pulls the brand's approved tone, locked rules and history before it acts.
  • Stay within approved rules. Rules live in the memory, so an agent can't propose a direction the client already rejected.
  • Log everything, with citations. Every action is recorded and sourced, so you can trust it and answer "why".

Isolation and control, built into the architecture.

Multi-brand memory is only safe if separation is structural, not a setting.

Isolated per brand

Each brand runs in its own brain. Nothing from one account is reachable from another.

Permission-inheriting

People and agents only ever see what the connected tools already allow them to.

Full audit trail

Every capture, answer and agent action is logged and sourced.

Your data, your control

Review, export or delete anything, anytime. Nothing trains a foundation model.

Everywhere your team works, all inside Sylvie.

The same memory powers every surface, so the context is consistent whether a person or an agent is asking, and nobody has to leave the tool.

Platform questions.

Everything happens inside Sylvie. Layer 02 ships the agents that do the operational work, briefs, updates, approvals and recall, end to end, and every surface reads from the same brain. Your integrations feed context in; your team never has to leave the platform to act on it.

RAG retrieves text fragments; it doesn't understand structure or precedence. The Brand Brain models approvals, rules, tone and relationships, and knows that a newer decision overrides an older one. It's a structured system of record, not just embedded text.

Isolation is architectural, not a permission toggle. Each brand runs in its own brain, so nothing from one account is reachable from another, and Sylvie inherits the access permissions of every tool it connects to.

Yes. Layer 01 reads from your tools continuously and updates as briefs, feedback and approvals change, deduping and re-linking as it goes. The context your agents draw on is always the latest, never a stale snapshot.
