AI Cowork Kit

In the end, you’re your AI’s assistant.

You re-explain everything, you fix its answers, you go over it again. What if it were the other way around? An AI that already knows your clients and your style, and hands you back work that’s ready to review.

Koa is your AI assistant: it finds and personalizes the right kit for you.

  • Free, no card required
  • Set up in a few minutes
  • No code, nothing complicated
What you tell Koa

I want to manage my email, tasks and meetings without re-explaining everything to the AI every single time.

What’s really going on

It’s not you, the problem.

You may have told yourself you didn’t really know how to use it. That others had some extra knack.

The truth is simpler. Think about what makes a person operational on your team: an identity, knowledge, know-how.

Your AI has none of the three. It may pick up a few scraps over time, but scraps in a pile are not an identity, not a profession, not know-how. So it answers the way it would answer anyone, and you do the rest.

As long as it’s missing all three, you’ll always re-explain everything.

How it works

The folder your AI reads before it works.

Not a prompt pack, not a course: a folder of simple files your AI opens before producing. That’s what we call the Dossier-Contexte.

  1. You

    You say what you want to handle better, in your own words.

  2. Your folder

    Koa prepares it: who you are, your rules, your first mission.

  3. Your agent

    Claude Cowork or Codex opens and reads it before working.

  4. Your deliverable

    You launch the mission: the agent already has all the context.

The mechanism

An AI Cowork kit gives it all three.

An identity

Who you are, how you speak, how you write. No more bland answers you can spot a mile off: it writes like you.

Knowledge

Your work, your clients, your deals in progress. No more long-winded explanations: it already knows what you’re talking about.

Know-how

Missions it can run end to end: sorting your inbox, prepping a meeting, drafting your follow-ups. No more copy-paste: you launch, it does the work, you review.

You answer a few questions, once. And it grows richer as you use it: after each meeting it updates the person’s profile, week after week your email templates settle into the way you write. It’s the AI that updates your files when you work with it, nothing happens behind your back.

The more you work with it, the better it knows you.

Inside a kit

See what it prepares for you.

Not a promise — a real file. Here’s a sheet your AI writes the night before a meeting, from what it knows about your work and your prospect. You read it on the way there, you walk in ready.

meeting/2026-06-11-dupont.md

Meeting: Thursday June 11, 10 a.m. — Mr. Dupont, owner of Dupont Joinery (small business, 6 staff).

Goal: walk out with an agreement in principle on rebuilding his website.

My 3 goals (in order)
  • Get an agreement in principle — the quote comes later.
  • Find out who decides: him alone, or someone else?
  • Leave with a date for the next step.
Likely objections (and my answer)
  • “It’s too expensive for a business like mine.” → Talk in clients won, not in cost: one job signed through the site pays for the rebuild.
  • “I don’t have time to deal with it.” → Two 30-minute meetings, everything else is prepared on my side.

A real excerpt from an AI Cowork kit. You get the file, tweak it once, and it serves you at every meeting.

How does it actually work?

01
You download your kit: just a folder, on your computer.
02
You open it in your AI app: the one that can work on your files. If you use ChatGPT, that’s Codex (same house, OpenAI); on the Claude side, it’s Claude Cowork. It installs like any other app.
03
You tell it: “read your brief and tell me what you can do for me.” It replies with its missions, you pick one, and you’re off.

Don’t have the app yet? install Claude Cowork or install Codex, both free to download — they work with your Claude or ChatGPT subscription.

AI Cowork Kit used inside an AI chat interface
The starting point · ChatGPT or Claude

In a chat, your AI reads your context but starts from scratch every time. That’s exactly what the kit gets you past.

AI Cowork Kit open on Mac: Finder, editor and AI assistant
Advanced tool · Claude Cowork

The folder open in Claude Cowork. The AI reads the context, you launch the first mission.

AI Cowork Kit open on Windows: file explorer and AI assistant
Advanced tool · Codex

The same folder in Codex. Same files, different tool, nothing to reconfigure.

Works with ChatGPT and Claude, and with Claude Cowork or Codex, the apps from Anthropic and OpenAI. The files are yours, kept even if you switch tools.

Yours, for good

The folder belongs to you.

Yours

Open files, editable, kept for life.

Portable

The same folder in ChatGPT, Claude or another tool.

No subscription

You pay for a kit once, updates follow.

Example feedbackThe kit just launched. Here’s the kind of feedback we’re aiming for — we’ll replace these with real testimonials as soon as the first testers come in.

Example

"I used to spend half a day prepping my meetings. Now I launch the mission, read it on the train, and walk in with a sharp brief. The thing is, it already knows my clients — I don’t re-explain anything."

Marine L.Independent HR consultant
Example

"I thought I just wasn’t good with AI. Turns out it simply didn’t know me. Since my emails come out in my own voice, I’ve stopped rewriting everything."

Thomas R.Freelance writer
Example

"One hour to set up, and that same evening it was sorting my inbox the way I would have. First time an AI tool saved me time instead of costing me time."

Sofia B.Solo founder
Ownership, updates, guarantee: the details

A paid kit isn’t just the ZIP. Your license keeps the tutorials and the updates switched on. But the files themselves are open and stay yours: no platform captures your data, nothing locks you in.

Ownership

Open files, editable, kept for life. No lock-in, no data captured.

Updates

New missions, fixes and examples as the tools evolve, without rebuying the kit.

Visible contents

Each kit lists its missions, templates and files on its page, before you buy.

14-day guarantee

Folder no use to you within 14 days? You email us, we refund you. No trap form.

The objections we hear most
"Isn’t this just a prompt pack repackaged?"

No. A pack is lines to copy into a chat that stays empty. Here, the AI reads a configured folder before it works. Watch the demo: you see the difference live.

"I can write an AGENTS.md myself."

Then the free Starter won’t teach you anything: compare it to yours. What you buy with a kit is the sequenced role method, the calibrated examples and the updates as the tools evolve.

"Will it actually work for MY line of work?"

Each kit lists its contents on its page (missions, templates, files) before you buy. And you can test the format with the free Productivity Kit.

"I’m not technical enough."

The install tutorial is in the folder, not an add-on. You open a folder in a tool you already know. Three minutes, and you’re producing.

"I don’t have time to do this myself."

That’s what the Guided setup is for: we configure your AI with you, on your real case, from €149. You leave with a system that runs.

Frequently asked questions

Which AI does it work with?

With Claude Cowork or Codex, the apps from Anthropic and OpenAI. If you already use ChatGPT, Codex comes from the same house (OpenAI) and can actually act on your files. You install the app, drop your kit in, and you’re off.

ChatGPT already has a memory, right?

Yes, and it keeps scraps, somewhat at random. Handy, but it’s scattered sticky notes. A kit is the opposite: your identity, your knowledge, your know-how, organized by project, that you can read, correct, complete. And if you switch tools, you take it all with you.

I’ve already built a custom GPT. What’s the difference?

Three things. Your kit follows you from Claude to Codex: you’re no longer locked into a single tool. It’s organized by project and updates as you work, instead of a frozen block of instructions. And its missions go all the way through the work, instead of just answering in the chat.

I’m not technical. Is it for me?

That’s exactly why it exists. The kit was built and fixed with testers who aren’t technical at all.

I’m afraid it will write “like an AI,” bland, not like me.

You give it examples of the way you write, and it uses them. The more you work with it, the closer it sticks to your style. Everything stays in your tool, nothing comes to us.

How long does it take to get started?

Just the time to download your kit and open it in your app: a few minutes. You launch your first mission right after.

Is it really free? Where’s the catch?

The Productivity Kit is free and open source, with no time limit. It runs inside your AI app, with your existing Claude or ChatGPT subscription. The specialist kits are paid — that is how we fund ourselves.

And my client data?

Your data goes into your AI app, on your account and your privacy settings. The kit adds no server between you and your tool. AI Cowork, for its part, sees nothing, stores nothing, sells nothing, and you can erase it all whenever you want.

Tomorrow morning, your AI can already know you.

You can keep re-explaining everything, in every conversation, for months more.

Or take a few minutes today, and never start over again.

And finally breathe.
