The operating system for client marketing

Turn marketing work into approved action.

Greylight brings content, outreach, SEO signals, and proposed ads into one shared client context. Today, AI prepares content and outreach, surfaces SEO context, and keeps proposed ads paused for review; people control what gets published, sent, or spent.

The loop

Six steps. One of them is yours.

Greylight runs the whole cycle end-to-end. The human gate sits in the middle by design — a deliberate constraint, not a limitation.

Your approval

Every draft waits here. Publish now, or approve with a schedule.

The approval step is the product's strongest claim: nothing bypasses it.
Capabilities

What Greylight does, said plainly.

One agent per brand, each with its own voice, its own rules, and its own history of what you've rejected before.

Six abstract brand marks arranged in a grid, one for each brand under the operator's care.

Per-brand agent
A separate voice for every brand.

Each brand gets its own chat agent, grounded in that brand's real data — not a generic AI writing generically for everyone.

Foundation scan
Onboarding without a brand brief.

Point Greylight at a website and socials. It extracts voice, tone, visual identity, and positioning automatically.

Queue & calendar
Every draft, in one line.

A single review queue and a shared calendar across brands. Nothing hidden in five different tabs.

Real publishing
It actually posts.

Instagram, Facebook, Threads, X, LinkedIn, email, and articles — direct publish, not copy-paste to another tool.

Ads, paused
Meta campaigns land paused. Always.

Greylight can build entire campaigns, ad sets, and ads on Meta — but every one of them is created paused. Unpausing is a manual step outside the tool.

Market eye
React, don't stare at a blank page.

Outreach research and competitive signals show up as things to respond to, not homework to start.

Feedback loop

Every rejection makes the next draft better.

When you edit a draft or send it back, that becomes a durable rule for that specific brand. The agent stops repeating the mistake — instead of forgetting it by tomorrow.

A single terracotta ink stamp on warm paper — the mark of an operator's approval.

Built for operators

Not enterprise software. A cockpit for one operator running several brands.

Greylight was built by a solo operator to run content across their own projects and paying client brands, without losing the thread of any of them. If that's your setup, you're the target user.

Calm interface, precise controls, no confetti.
Access is invite-only

If you run marketing for more than one brand, we should talk.
