Here's the email, in their voice, with their numbers. I also found a stale claim in the old promo doc and flagged it for review.

This is the Vault working. Simulated conversation, real system.

The AI isn't the problem.
The re-brief is.

Your team already uses AI. But without the client's facts, every task starts from zero, in every seat, on every tool.

The re-brief

Every deliverable starts with re-explaining the client to the AI. Again. Every person, every tool, every time.

01
02

The generic draft

Without the client's facts, the AI guesses. The draft comes back sounding like nobody in particular.

The babysitting

A senior person rewrites the output line by line. That's your margin leaking into the rewrite step.

03
04

The slow ramp

A new hire takes months to learn each client. The knowledge lives in heads and old decks.

Multiply that by every client and every seat.
That's the re-brief tax.

We build each client a Vault.
Every seat reads from it.

Hand us the messy client folder. We refine it into one clean, governed reference kit. Most AI consultants teach. We build, install, and stay until your team owns it.

FAQ

The short version, answered.

What is Storystak?

Storystak builds each of a marketing agency's clients a governed Client Vault: one source of truth for brand, voice, audience, offers, and sourced stats that every team member's AI tools read from. It ships white-label under your agency's own name.

What is a Client Vault?

A Client Vault is a single governed reference kit for one client: brand guide, voice rules, audience notes, approved offers, and statistics with every number tied to a source. Whatever AI your team already uses points at it, so drafts come back on-brand and factually sourced.

Which AI tools does it work with?

It works with the AI your team already uses, including ChatGPT, Claude, Copilot, and similar assistants. There is no new software to install and no prompts to memorize; each person simply points their own assistant at the Vault.

How is this different from a prompt library or a brand guidelines doc?

A prompt library still relies on each person re-explaining the client every time. The Vault is a governed source the AI reads directly, with every stat tied to a source and stale claims flagged, so output stays consistent across people, tools, and time.

Client Vault vs. the usual alternatives
Capability Prompt library Brand guidelines doc Storystak Client Vault
AI reads it directly No — copy/paste each time No — a PDF for humans Yes — every seat points its AI at it
Stats tied to a source No Rarely Yes — every number sourced
Stale claims flagged No No — goes out of date silently Yes — flagged, not published
Consistent across the whole team No — depends who's prompting Depends who reads it Yes — one source for every seat
Works with existing AI tools Per person, per tool Not built for AI ChatGPT, Claude, Copilot — no new software
White-label resale to clients No No Yes — ships under your agency's name
Can we resell Vaults to our own clients?

Yes. Every Vault ships under your agency's name, powered by Storystak. Agencies bill it to clients as their own AI-onboarding line item, a deliverable competing agencies don't offer.

How long does setup take?

Your agency is set up once at kickoff: voice, standards, and folder structure, with training included. From there each client Vault is built per client from your existing folder, and your team plugs in on day one.
