# Storystak > AI remembers what you uploaded. A Stak knows what matters. Storystak puts what matters about each of a marketing agency's clients into one governed record, a Stak, that every AI the team uses (Claude, ChatGPT, Gemini, Grok) reads over MCP, with a source on every fact and a person approving every change. --- ## About this page This is Storystak's official overview, published by Storystak at https://storystak.com/overview.txt and kept in step with the homepage. It is plain text so it reads in full anywhere, including in an AI assistant. It covers what Storystak is, how it works, pricing, client data, and who it is for. Last updated 2026-11-10. Questions this page doesn't answer, such as timelines or anything specific to one agency's clients, are what the free 30-minute call is for. The tour, Dot and the call are listed at the end. --- ## What Storystak is AI remembers what you uploaded. A Stak knows what matters. Instead of every person re-explaining a client to their AI on every task, each client gets one governed record of what matters about them, the Stak, with a source on every fact and a person approving every change. The agency gets one too, for its own voice and standards. An agency gets a Storystak Suite: the Staks, which every AI the team uses reads over MCP; the kits, workflows and systems that read the same Staks; and the Surface, the web app where the team sees what is being read, what is missing, and every change waiting for approval. Switch AI tools and the Stak comes with you. --- ## The problem it fixes Every agency has the same AI now. Generic is the part of the work a client can now get without you, so the fee is at risk when the draft could have come from anyone. Inside the agency, five people hold five versions of the client, a fix in one chat never reaches the next, and the brand guide gets pasted in for the fourth time this week. A prompt library doesn't fix it, because it still relies on each person re-explaining the client. A brand guidelines PDF doesn't fix it, because AI doesn't read it and it goes out of date silently. The Stak fixes it at the source: one governed record the AI reads directly, kept current by the work. --- ## What a Client Stak is A Client Stak is one client's record of what matters: brand, voice, audience, offers, the numbers with their sources, the decisions, and the things you would never do for this client. Whatever AI your team already uses points at it, so drafts come back on-brand and factually sourced. Each client's Stak is walled off from every other client's in code, and each person sees only the clients they are on. Governance is the point. The AI reads and can propose a change, but never makes one: anyone who notices something wrong or out of date files an update request, a person reviews the change, and every approved change is logged and individually reversible. Searches that come back empty are logged as gaps, so the agency can see what its team needed and couldn't find. Numbers get a clock: a canonical stat nobody has confirmed in 120 days is flagged on the Surface. Everything else waits for someone to notice, so someone still owns accuracy for each client; the Stak makes that a quick review instead of a documentation project. --- ## How it works The homepage tells it as a story in two chapters. **Your agency today.** The client says a lot on Thursday's call. Then it gets passed along to account team members. Everyone briefs their own AI from what they got. The work comes back fast, but it's generic AI output. So it all rolls uphill to your best people to check and correct it, every week. **Your agency with Storystak.** 1. **Each client gets a Stak: one record, set up for you.** We draft it from your files and calls, in a working session with your team, and your team approves what goes in. Every fact keeps its source. 2. **The lead adds Thursday's call.** Each change comes back as a suggestion, with where it came from. 3. **The lead says yes.** In a click, from their AI or the Surface. Nothing in a Stak changes until a person approves it. 4. **Every AI reads the new version.** Nobody pastes anything. 5. **The loop.** Every call, every plan, every report keeps it current, and someone new starts from all of it. 6. **All of it.** Then every client, plus how your agency works. Nothing crosses between clients. --- ## How a Stak gets built 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. 1. **Add the client.** A name and a website start it. Brand guides, decks and service docs you already have make the Stak sharper. 2. **Storystak research.** 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. 3. **Question guide.** The gaps become a short question list, at most about fifteen: only what research can't answer, ordered by impact. 4. **Dot** (you, or your client, talk). Answer by talking. Dot, the voice interviewer, works through the question guide; answers come back as Stak updates you approve. --- ## Dot, the voice interviewer The last step is a conversation, not a form. You open a private link, enter your PIN, and talk for a few minutes while Dot works through your question guide. 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. Live voice demo: https://storystak.bot/demo --- ## Which AI tools it works with The AI your team already uses, over MCP, an open standard. Claude, ChatGPT, Gemini and Grok all connect to the Stak. There is no new software to install and no prompts to memorize; each person points their own assistant at the Stak, and if the team switches tools the Stak comes with them. **Does everyone have to switch to Claude?** No. ChatGPT, Gemini and Grok connect too. 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 connected, each one reads the Stak; ChatGPT can also file corrections, asking you to confirm each one. We recommend Claude on capability, not preference. Keep every tool you like. --- ## Pricing You pay only for active clients. Two ways to pay: - **By the year: $75 a month for each active Client Stak.** Five Client Staks are prepaid at signing ($4,500), setup is included, and the price is locked for 24 months. Founding agencies get these terms while founding seats last. - **Month to month: $100 a month for each active Client Stak**, billed on the 1st, plus a $1,500 one-time setup. Stop any month. - **Both include** unlimited seats (staff, freelancers and contractors cost nothing extra), the agency's own Stak, the Suite and the Surface at no charge, every kit, your workflows set up with us, and setup done for you in a working session. Reports and Landing Pages are systems, priced per client they run on. - **Active means:** retainer clients are active all year. Project clients are active while the project runs. A project client costs the same as a retainer client. No minimum. Switch a client off and it is paid through that month, then nothing; switch it back on any time. - **Prorated when you add.** A client added mid-month bills for the rest of that month. - Leaving: a clean export of every Stak at no fee. --- ## Is client data safe? What a client tells you stays with that client. Each Stak holds only what a person approved, is walled off from every other client's in code, and is served to the team's AI tools over an encrypted connection. The AI can read and suggest, but never change anything: every proposed change is a reviewed, human-approved update with a permanent record. It's the agency's content, in version control, with a clean export at no fee if you leave. --- ## Who it's for Independent marketing, creative and advertising agencies whose teams use AI to produce client work, typically with 15 or more active clients. Roles served include owners, ops leads, account leads, strategists, creative directors, copywriters, designers, producers, paid-media managers, and new hires ramping onto accounts. --- ## Who's behind it Storystak LLC is a Tennessee company, founded in 2026 by Zach Worley and Dan Muirhead, who both came up in agency work. Zach Worley, Co-founder, Product & Services, spent more than 16 years in marketing and creative services building the systems behind the work, and built the first Stak for marketing teams he worked with. Dan Muirhead, Co-founder, Growth & Partnerships, spent 15-plus years agency side, mostly leading media strategy at Omnicom Media Group and Wpromote, and co-founded AIVO, an AI-first consultancy on AI search, before joining Zach.
