In August 2026 we took one agency client's real folder, the same folder the team was uploading to AI chats, and counted. The folder held about 9,500 tokens of readable text, but one chat cost about 50,000 tokens to load it, most of that spent processing PDF pages the AI cannot read as text: a scanned agreement, a designed branding guide whose columns scramble on extraction, a metrics spreadsheet that turned out to be empty. Rebuilt and expanded into the Stak, that same client knowledge grew six times deeper, and a typical task reads about 7,000 tokens of it. Fewer tokens in, better context, every chat, every seat.

This is the Stak 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.

The slow ramp
A new hire takes months to learn each client. The knowledge lives in heads and old decks.
The re-brief tax, measured.
We counted it on a real client build: the folder the team was actually uploading to their AI, against the Stak we rebuilt and expanded from it.
~86% fewer tokens
spent per chat. Same client, same task.

What's the story here?
We build each client a Stak.
Every seat reads from it.

On Your Stak
One source of truth.
Everything else sits on it.
Each client’s Stak holds the facts. The work your team does with them sits on top and reads from it.
The Stak
One source of truth
Each client’s facts, in one place your whole team’s AI reads from. Three things sit on top of it.
Kits

Together
One system
Kits, workflows and systems all plug into the same Stak, so every tool and every seat works from the same facts.

The Process
How We Refine Your Stak
A Stak is only as good as the knowledge inside it. Four steps take it from a name and a website to a voice interview that fills in what only you know. No blank-page homework.
You hand off
01
Add the Client
A name and a website start it. Brand guides, decks and service docs you already have make the Stak sharper. Nothing starts from scratch.
We research
02
Storystak Deep Dive
Our research builds the first draft of the Stak in about ten minutes, and you review it before it goes live. Anything unverified is logged as a gap, never guessed.
We ask
03
Question Guide
The gaps become a short question list, at most about fifteen: only what research can't answer, ordered by impact.
You (or your client) talk
04
Storystak Bot
Answer by talking. Dot, the voice interviewer, works through the question guide; answers come back as Stak updates you approve.
The Storystak Bot
The Last Step Is a Conversation
Not a form. Dot interviews you by voice, and the Stak gets sharper every time you talk to her.
Your Stak Asks.
You Just Talk.
Open your private link, enter your PIN, and talk for a few minutes. Dot works through your question guide, and every answer lands in your review queue as a pending Stak update.
- Don't have the answer? Your client does. Send them the same link; their answers land in the same review queue, and you still approve every change.
- Asked once, never again. A filed answer retires its question for good. Every session picks up where you left off.
- You approve every change. Dot never writes to a Stak. A person signs off on every update.
How It Works
Three moves. Then it just runs.
Once, at kickoff
01
We set up your Suite
Your agency's own Stak (voice, standards, how your team works) and the Surface, mirrored to how your team already works. Training included.
Per client
02
Add a client, get a Stak
Our research builds it, you approve it, and the client fills the gaps. One clean reference kit, every stat tied to a source.
Day one
03
Your team plugs in
Each person points their own AI at it. No new software, no prompts to memorize. The Surface shows who is using what, what is missing, and every change waiting for approval.
Why I Built This
AI without human expertise is just a calculator.
I spent 16 years building marketing systems before AI existed. When it arrived, my first thought was that my career had a shelf-life. Then I remembered Photoshop, when everyone said it was the end of real design. The people who adapted didn't lose their careers. They unlocked a new level of them.
I jumped in head first and found the same thing. AI without human expertise is just a calculator. But apply 16 years of knowing how great work actually gets made. And the ceiling disappears.
That's what we encode into your systems.
My job isn't to sell you another AI license. Your team already has one. It's to make sure everyone on it, and every tool they use, works from the same approved picture of each client. This is tech, but it really is about people.

Custom tools and reporting builds are scoped separately, in writing, and never folded into the monthly price.
FAQ
The short version, answered.
Questions
Answer
What is Storystak?
Storystak builds each of a marketing agency's clients a governed Client Stak: one source of truth for brand, voice, audience, offers, and sourced stats that every team member's AI tools read from. Your agency gets a Storystak Suite: the Stak your AI reads, and the Surface, where your team sees what is being used, what is missing, and every change waiting for a person to approve it.
What is a Client Stak?
A Client Stak 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.
What is the Storystak Bot?
A voice interviewer named Dot, who fills the gaps research can't. You open a private link, enter a PIN, and talk through a short question guide; every answer comes back as a pending Stak update a person approves. Dot never writes to a Stak directly, and an answered question is never asked again. Try the live demo.
Which AI tools does it work with?
The AI your team already uses, over MCP, an open standard. Claude is the one we test end to end; ChatGPT connects too, on a Plus or Pro plan in a browser. There is no new software to install and no prompts to memorize; each person points their own assistant at the Stak.
Do I need a team ChatGPT or Claude account?
No, but it can help. Your team can point individual ChatGPT or Claude accounts at the Stak just as easily as a team plan. Access is your call, person by person: full-time employees, freelancers, or a contractor brought in for one project. When the project ends, so does the access.
Does everyone have to switch to Claude?
No. The Stak connects to ChatGPT too. What you should know: in ChatGPT it needs a Plus or Pro plan, it runs in a browser, and setup goes through Developer mode in the security settings instead of one click. Once it’s connected, ChatGPT reads the Stak and can file corrections, asking you to confirm each one. Claude is the team-shaped platform and the better prompt writer, which makes every other tool better: Claude plus the Stak writes the prompt, and you take it to ChatGPT, Nano Banana, Higgsfield or Gemini for the image or the video. That is why we recommend Claude, and the reason is capability, not preference. Keep every tool you like.
How is this different from a prompt library?
A prompt library still relies on each person re-explaining the client every time. The Stak is a governed source the AI reads directly, with every stat tied to a source and every change approved by a person, so output stays consistent across people, tools, and time.
Why not just upload my own context files?
It works, just not well. Files get re-uploaded chat by chat, nothing ties a number to a source, and old decks linger long after the facts change. Each person also grabs different files, so every seat gets a different picture of the same client. The Stak replaces that pile with one governed source every tool reads the same way.
Can I do this myself?
In part, yes. A solo marketer with clean files and discipline can get real value uploading their own context. The gap shows up with a team: everyone keeps their own version, the versions drift, and nobody notices the stat that went stale. Storystak adds governance at team scale: one source every seat reads, every number tied to a source, and every change approved by a person. That keeps the tenth seat's drafts as consistent as the first's.
How long does setup take?
Your agency’s Suite is set up once at kickoff, with training included. Adding a client takes a few minutes: our research builds the first draft of their Stak in about ten, you review it, and at most about fifteen questions only the client can answer go to you, to Dot, or to a short call. Expect your first client to be live within about a week.
What does it cost?
$100 a month for each active Client Stak, billed on the 1st. A client added mid-month is prorated for the rest of that month. Seats are unlimited, there is no setup fee, and it is month to month. Your agency’s own Stak, the Surface, Dot and training are included. The free trial includes one Client Stak. See pricing.
