Claude, out of the box

Claude
YouA client is two weeks late on my €6,200 invoice. Write my next message.
Claude

Hi [Client Name], I hope you’re doing well! I’m following up on invoice [number], which is now two weeks overdue. Could you please let me know the status of the payment? I’d really appreciate it. Thanks so much!

Claude with your Gerty agent

Claude
YouA client is two weeks late on my €6,200 invoice. Write my next message.
Your Gerty agent

[Name], invoice [number] (€6,200) was due on [date]. Pay it by [date, three working days out], or tell me by then when it will be paid. If something is blocking it, tell me what and who owns it. I’ll fix my side the same day.

It names a date, offers a way out, and skips the apology. Because that’s how you write.

What you finish with

A certificate you can share.

A certificate of completion to share with your colleagues and on LinkedIn, with a PDF and an Add to LinkedIn button. Yours carries your name and date.

How it works

It starts with a conversation. Yours.

One afternoon, at your own pace. Claude asks, you answer.

  1. Pick what goes in.
  2. Get interviewed.
  3. Get your agent.
  4. Test it on real work.

With the session: we do steps 3 and 4 together, and I show you how to connect the tools Claude supports, like Gmail, Calendar and Drive.*

* Where your Claude plan and your company’s IT policy allow.

in your Claude account
Step 1
Pick what goes in. Emails, posts, notes: whatever shows how you think. You choose what to share.
Here are a few things I wrote that I’m proud of.
Step 2
Get interviewed. When a client pushes back on price, what do you do first? What would you never say?
I never apologize for the fee. I ask what they’re comparing it to.
Step 3
Get your agent. Claude turns your answers into your voice and your decision rules, inside your own account.
Step 4
Test it on real work. Where it misses, you say so and it gets fixed.

Connect the tools you already use.*

A fair question

Claude already has memory. Why Gerty?

Memory and custom instructions are empty boxes. Gerty fills them with how you decide.

G
Gerty
answers
I could write custom instructions myself. What does Gerty add?
An interview. Twelve questions, one at a time, that pull out how you decide. Hard to write from a blank page.
Then your own writing sets the voice. You correct it before anything is saved.
Then five tests on real tasks. Memory still works the way it always did.

What changes

You stop pasting context into every chat. First drafts come out close to what you would send.

Your one-time investment

One afternoon, and one payment. No subscription.

What stays the same

You decide and you send. Claude stays Claude, under Anthropic’s terms and your settings.

Is it for you?

Made for people whose thinking is the work.

You should get it if:

  • You use AI most weeks and still re-explain yourself.
  • Your writing or judgment is the work: emails, proposals, advice, decisions.
  • You want it done in one afternoon.

All you need

  • An AI account: Claude, ChatGPT, Copilot or another.
  • One afternoon.
  • Some of your own emails or notes. A few is enough.

What you walk away with

  • An AI agent that writes like you and thinks like you.
  • A method you keep, on any AI platform.
  • A certificate of completion

Does it sound familiar?

Your AI is capable. It just doesn’t know you yet.

You have probably felt all three lately.

It sounds generic

Polite, smooth and nothing like you. So you rewrite every draft.

It knows about you. It doesn’t think like you.

It can read your notes. It can’t tell what you would decide, or why.

Setup is overwhelming, and it’s never over

Prompt libraries, custom instructions, a whole weekend. Then nobody maintains it.

Who is behind it

I’m Tomás, founder of Gerty.

For 15 years I’ve helped thousands of people make technology work for them, at Netflix, Google, Booking.com and Miro, where I led our AI Transformation. Now I do it one person at a time, with AI.

Questions

Things people ask first

Before you buy

What is the kit, exactly?

The kit arrives by email right after checkout. You add it to a new Claude chat, type Go, and Claude interviews you from there. Nothing to install.

Do I need to be technical?

No. No code, nothing to install. You talk to Claude and answer its questions, like with a good new colleague.

Which Claude plan do I need?

Claude Pro is recommended. The build is a long conversation, and the result lives in a Claude Project. If your plan cannot create a Project, the kit has a fallback: you keep the two blocks it writes as notes and use them in a new chat. Plans and limits change, so check yours first.

Are there other costs?

One payment, no subscription. Your AI plan is separate and paid to its provider.

Will you see my writing?

No. Everything stays in your own account. In the session, you decide what to show me.

How is this different from Claude’s memory or custom instructions?

Memory and custom instructions are places to put things. Gerty finds out what to put there: a twelve-question interview on how you decide, your own writing for the voice, and five tests before you rely on it. Memory keeps working the way it always did.

What if I get stuck?

Reply to your delivery email and we help. With the session, we sort it out on the call.

How it works

How long does it take?

One afternoon, in one or two sittings. With the session, add 45 minutes with me.

What happens in the 45-minute session?

We build and test your agent together on your real work, and I show you how to connect your tools where your plan and IT allow. A short intake comes first so we start where you are. I take 6 sessions a week, so a slot can be a week or two out.

Do I need a lot of my own writing?

No. A few emails or posts you’re happy with help it sound like you. The interview does most of the work.

Does it connect to my email, calendar or files?

Claude can connect to tools like Gmail, Google Calendar and Drive, where your plan and your company’s IT allow. In the session I show you how. Your agent never sends anything on its own.

Does it run on its own?

No. Every task starts with you, and you send what goes out.

Will it think exactly like me?

No. It works from what you tell it and will miss sometimes. You test it before you rely on it, and you correct it in plain words.

Is this a prompt pack?

No. A prompt pack gives you text to paste. Gerty interviews you, builds your agent with you and tests it.

Which AI platforms does it work on?

Claude, OpenAI, and most AI platforms. At checkout you choose the one you use. Claude is ready now. For ChatGPT, Copilot and others, your order is confirmed today and the kit arrives by email on 10 November.

What happens when Claude changes?

Your agent is plain text you own, so it keeps working. The kit includes an update routine for when your work changes.

Yours to keep

Do I own what I build?

Yes, and it moves with you to other AI platforms. The kit itself is for your own use: please don’t resell or share it.

Can my company pay?

Yes. See learning budget for a company invoice and a ready message to your manager.

Can I give it as a gift?

Yes. You get a voucher right away, to print or forward, on the gift page.

Build your agent this afternoon.

Either way, you end the afternoon with an AI agent that writes like you and thinks like you.
