Everyone is talking about how AI saves time. Hardly anyone has any figures on this. The AI Time Voucher changes that: You enter two numbers and get a voucher printed out showing your personal time savings. Free, no registration required, in ten seconds.
In almost every workshop, I hear the same phrase: “AI saves us an incredible amount of time.” When I ask exactly how much, everyone goes quiet.
That’s understandable. No one wants to have to track their time on top of their regular work. But this leads to a real problem: Without data, you can neither justify a budget nor identify where AI actually isn’t helpful at all. And there are tasks where AI isn’t helpful. They just fade away in the good mood.
On top of that, there’s a common mistake that almost everyone makes: we forget about the follow-up work. The text comes through in the chat in two minutes, and then we spend twenty minutes tweaking it. But the number two sticks in my mind.
That’s exactly what the AI Time Voucher is for.
The AI Receipt is a small web tool that looks like a cash register receipt. You enter a task, and instead of an amount in francs, you see the time saved in minutes. It runs in the browser, on your phone just as well as on your laptop.
How long would it have taken you without AI? How long did it actually take you? That’s all it takes.
With just one click, the receipt calculates how much time you’ve saved. Each task you log appears as an item on your receipt.
The tool adds it all up: tracked tasks, time without AI, time with AI, and, at the very bottom, the time saved. And if you’re diligent, you’ll unlock little coupons along the way.
WHAT THE BON CAN DO:
Not every task is completed faster with AI. Some people even slow down because rework takes up all their time. Only when you see both side by side can you decide where to use AI and where it’s better to do without it.
“AI saves us time” is a feeling. “We saved 62 hours in four weeks, 41 of which were spent writing texts” is one argument. This applies just as much to management as it does to the team.
Anyone who writes this down should pause for a moment and ask themselves: Is AI the right choice here? This short break has a greater impact on usage than any training session.
Time saved goes to waste if no one acknowledges it. Once it’s on a receipt, you can discuss as a team what to do with it. Finish work earlier, more time for customers, less overtime. That’s a decision, not a matter of chance.
The receipt is the sales slip. The AI time account is the account statement.
The Excel template builds on that same idea and takes it a step further: It also tracks the amount of follow-up work required, the quality of the result, the type of task, and the AI tool used. And she figures out which activities and tools will actually be most effective for you.
I use them myself in workshops and in projects with clients. That’s why it’s designed so that it’s still being used after the second week and doesn’t fall by the wayside after just the third day.
One page, two rules, one example. That’s all the introduction you need.
400 prepared lines. For each task, you fill out six fields, almost all of which are drop-down menus. You only need to enter the date and the assignment name. Fill in the fields highlighted in yellow; the white ones are calculated automatically.
Calculates automatically:
All dropdown values in one place. Twelve task types and sixteen AI tools have been prepared, including ChatGPT, Claude, Gemini, Microsoft Copilot, Perplexity, SwissGPT, Kontexus, Mistral, DeepL, NotebookLM, and GitHub Copilot. If something is missing, just add it on a new line.
THE HEART OF IT ALL: THE RATING
The template focuses not only on minutes, but also on quality. Based on both of these, one of four ratings is automatically generated:
These four categories are the real reason why the template exists. Otherwise, simply counting the minutes can quickly lead to the conclusion that AI is always good.
You use AI every day and finally want to know if it’s worth it. Start with the voucher and complete each task for one week. After that, you’ll know more about your day-to-day work than you would after reading any time-management book.
You should explain why the company pays for AI licenses. With this template, after four weeks you’ll have real numbers instead of anecdotes—including the unpleasant ones: Even mistakes become apparent, and that’s exactly what makes the numbers credible.
You need something that people will fill out on their own. The coupon works because it’s fun and takes ten seconds. The template works because it consists almost entirely of drop-down menus.
Use the voucher as a starting point and the worksheet as homework between appointments. If you’d like to use this for your own commercial training sessions, just send me a quick message, and we’ll sort out the licensing in five minutes.
Before you start, think about how long it would have taken you without AI. Write down this number first. Those who estimate after the fact almost always underestimate the cost, because the immediate result clouds their judgment. A rough estimate beforehand is worth more than a precise one afterward.
Correcting, checking, rewriting, verifying sources, and starting all over again: All of this is part of working with AI these days. Without this figure, any use of AI looks like a profit. This number is where things get interesting.
Yes. No account, no email address, no trial period that expires at some point. The KI-Zeit-Bon is and will remain free.
No. Just go to bon.hundertmark.ch and get started.
Right in your browser, on your device. I don’t see your posts, and I don’t evaluate them. Just click the “Delete All Receipts” button, and they’ll be gone.
Yes. If you open it on a different device or in a different browser, you’ll start from scratch. If you want to track data across multiple devices, the Excel template is a better option.
Yes, the tool is designed for cell phones, tablets, and desktops. On a cell phone, you’re most likely to log a task right after you finish it, and that’s exactly when the numbers are the most accurate.
A little reward on the side. The more time you collect, the more you unlock. It’s nothing you have to redeem, but it makes the process a lot less tedious.
Because the original document answers other questions. The receipt shows you how much time you saved. This guide shows you where to shop, what to buy, and at what price for the quality you want. If you just want to measure for yourself, the receipt is more than enough. If you need numbers that someone else should see, use the template.
Microsoft Excel, version 2016 and later, on Windows and Mac. It can be opened in Google Sheets and Apple Numbers, but drop-down menus and formatting may become misaligned. For full functionality, I recommend Excel.
Immediately after payment, via email with a download link. If you haven’t received anything in ten minutes, please check your spam folder, and if it’s not there, send me an email at sophie@hundertmark.ch.
Via Stripe, credit card, TWINT, and other common payment methods. If you’d like an invoice for multiple licenses, please send me a quick message.
This purchase is for a single-user license for your own professional and personal use. If you’d like to use them throughout your team or company, please get in touch, and we’ll work out a fair solution. I need a separate agreement to use this in my own paid training courses.
Yes. On the “Lists” sheet, enter your own values. For the activities and tools, you must also add the new row to the “Evaluation” sheet so that it is included in the calculations. That’s also noted in the file.
The German version is currently available. If you need a different language version, let me know—I’m compiling the requests.
Digital products cannot be exchanged after they have been downloaded. If something isn’t working or the file isn’t what you expected, please contact me anyway. We’ll find a solution.
Two to four weeks is a good timeframe. The data becomes meaningful once there are about twenty entries in total; for comparing individual activities or tools, it becomes meaningful once there are about five entries per line.
Yes. It’s not about precision down to the minute, but about orders of magnitude and patterns. Whether a task would have taken 90 or 100 minutes makes little difference to the result. Whether AI saves twenty minutes or costs fifteen minutes makes all the difference.
These are a special case, because in this situation you’re not saving time—you’re doing something extra. Either don’t record it at all, or honestly enter “zero” for “Time without AI.” Then the task goes into the evaluation, and at the end you’ll see how much extra work you’re doing.
Then, in four weeks, you’ll have learned something that takes others years to learn. It’s perfectly normal for some missions to end in failure. The only thing that matters is what you do differently afterward.
No, and that’s not the goal either. These are self-reported data with estimated comparative values; they are not a controlled study. This is sufficient for internal decisions and business cases, as long as you specify it exactly that way.
Yes. My “End of the Workday with AI” program works exactly according to this logic: The team spends half a day building their own AI automations and directly converts the time saved into an earlier end to the workday. This program is available on-site, as a series of courses, and as a team-building day at the company. Write to me, and I’ll send you the details.
Talk to me. Customized versions, custom branding, or team reporting are available.
You’re very welcome. Email me at sophie@hundertmark.ch—I read every message myself.
