The second brain your marketing team needs.

Sylvie is a second brain for marketing teams. It connects your tools, builds a living brain for every brand you run, and deploys AI agents that execute the operational work. One brain per brand, in-house or agency.

Those are excellent general-purpose agents, but they start every session from a blank page. Sylvie is the layer they are missing: it stays connected to your marketing stack, keeps a living brain per brand that updates on its own, enforces each account's approved rules, and keeps every brand isolated from the next. A general agent can draft once you paste in the context; Sylvie already holds it, keeps it current, and runs on your behalf between sessions. You can even point your own agents at Sylvie as their shared memory.

Slack, Google Drive, Meta Ads, Google Ads, Notion, Gmail, Figma, HubSpot, and more. You connect once, and Sylvie reads from all of them. New integrations ship regularly.

Sylvie watches the tools where the work happens and updates each brand's brain as briefs, feedback, and approvals change. The context your team and agents pull is always the latest, not a stale export.

Sylvie stores structured memories and summaries, not copies of everything. You choose what each brain captures, and you can review and delete anything at any time. Your data is never used to train foundation models and is never shared with third parties.

Every brand lives in its own isolated brain, so nothing from one account bleeds into another. Data is encrypted in transit and at rest, and Sylvie respects the access permissions of the tools it connects to.

Any marketing team running more than one brand or campaign, in-house or agency, where operational coordination eats into the creative work and context leaves when a teammate does.
