Ketelsen.ai is my ongoing experiment in AI prompt engineering and human-AI collaboration. The goal has always been the same: go beyond the obvious prompt ideas — past the "write me a blog post about X" suggestions that flood every AI tips list — and get to the prompts that are actually creative, actually useful, and actually new.

This experiment has been years in the making, and it keeps evolving. What started as a one-person prompt lab has grown into something more structured, more reliable, and more ambitious.

The Person Behind the Experiment

While this website isn't solely about me, my background plays a significant role in how this experiment works. Here's a brief overview:

• 8+ years as a Design Director at an industry-leading Identity Design firm

• 10+ years as an entrepreneur in the fast-paced tech industry

• 5+ years as a Senior Cybersecurity Incident Responder at a Fortune 100 company

When Generative AI became mainstream in 2023, most people were fascinated by its potential. I found myself thinking, "Where was this 10 years ago?" and "Imagine how much faster and better I could have automated tasks back then." For over a year, I meticulously noted every possible task that could be automated — tasks that once consumed hours as an entrepreneur. Now, with AI, these same tasks can be completed in seconds.

Ketelsen.ai is the culmination of that thinking — a place where I apply everything I've learned about design, technology, cybersecurity, and entrepreneurship to the craft of AI prompting.

Ketelsen.ai 1.0 — Where It Started

The original Ketelsen.ai was a one-person operation. I would research a prompting topic, write the prompts myself, test them across Claude, ChatGPT, and Gemini, and publish the results. It worked. The prompts were good. But the process was entirely manual — every decision about topic selection, prompt structure, quality, and format lived in my head.

That meant the quality of each week's prompts depended on how much time I had, how fresh my thinking was, and whether I remembered what worked three weeks ago. There was no system. Just effort.

What the original version did well was prove that the concept works: you can consistently find creative, practical AI prompts that solve real problems — prompts that go far deeper than what most people think to try. Over time, this grew into a collection of over 1,000 in-depth AI prompts covering real-world problems, each generated and tested across multiple AI platforms.

Ketelsen.ai 2.0 — A New Experiment

Behind the scenes, I've been building something called CRAFT — Configurable Reusable AI Framework Technology. It's a structured system for communicating with AI that borrows ideas from object-oriented programming and applies them to AI conversations.

CRAFT started as a way to make AI interactions more reliable and repeatable. Over months of development across multiple projects, it grew into a full framework with recipes (reusable instruction sets), cookbooks (organized collections of recipes), a persona system, session handoffs for continuity across conversations, a lessons-learned system that captures what works and what doesn't, and version-controlled project files backed by git.

When CRAFT reached a level of maturity where it could reliably manage a real weekly content workflow, the question became obvious: what happens when you point this system at Ketelsen.ai?

Welcome to Ketelsen.ai 2.0.

Ketelsen.ai 2.0 builds on the original goal — finding creative, useful prompts that go beyond the obvious — but now uses CRAFT as the engine. The aim is to improve the usability, accuracy, reliability, and effectiveness of every prompt we publish. For now, you may not notice a difference in the weekly posts. But underneath, CRAFT is learning and improving the process every single week.

What's New in 2.0

Solve real problems with the best available tools. Each week, Ketelsen.ai provides prompts across a range of difficulty levels — from beginner-friendly to advanced — all designed to work across Claude, ChatGPT, and Gemini. Every prompt targets a specific, common problem that people actually hit when working with AI.

Continuous improvement built into the process. The framework doesn't just generate prompts. It tracks what works through a formal lessons-learned system, validates structural quality through automated checks, and evolves its own processes based on accumulated experience. The system captures distinct lessons that directly improve future output — and those lessons compound over time.

Measurable improvement over time. This isn't a static blog. The goal is for the quality difference between Week 1 and Week 52 to be obvious to anyone reading. CRAFT makes that possible because every improvement is captured, codified, and applied going forward — nothing gets lost between sessions.

How 1.0 Became 2.0

The core difference is this: the original Ketelsen.ai used prompts created entirely by me to produce the weekly content, while Ketelsen.ai 2.0 uses a custom-built CRAFT system that allows me to team up with AI through direct human-AI collaboration.

In practice, that means:

A custom recipe system built specifically for this project. Each recipe handles a different stage of the weekly workflow — from establishing context across AI platforms, to generating prompt variations at multiple difficulty levels, to creating visual assets with distinct creative angles, to running quality review gates before anything gets published.

A full year of topics grounded in real research. The content calendar was built by analyzing deep research covering everything from common AI frustrations and prompt literacy gaps to underutilized features and emerging capabilities. Every weekly topic is mapped to specific research findings, not guesswork.

A standardized blog post template that ensures format consistency across every week. Before this, each post's structure was slightly different depending on when it was written. Now there's a single source of truth.

Automated quality checks. Every weekly output goes through structural validation that catches formatting issues, missing sections, and inconsistencies before they reach readers.

Cross-platform prompt design. Every prompt is designed to work across Claude, ChatGPT, and Gemini without platform-specific syntax. You pick the tool you prefer and the prompt works.

A system that actually learns. When we discover that a particular approach produces better results, that becomes a permanent improvement. The system accumulates intelligence over time instead of resetting every week.

Session continuity. AI conversations normally start from zero every time. CRAFT's handoff system preserves context, decisions, and project state across sessions — so Week 10 builds on everything learned in Weeks 1 through 9.

What This Means for You

If you're a Ketelsen.ai reader, the most important thing is this: the prompts are going to keep getting better. Not because I'm working harder, but because the system that produces them is designed to improve itself.

Each week's prompts feature a practical, creative approach — with clear instructions, real examples, and techniques that work across all major AI platforms. Whether you're a beginner trying your first AI prompt or an experienced user looking for techniques you haven't seen before, there's something here for you.

The difference now is that the machinery behind them is more rigorous, more consistent, and more capable of surfacing genuinely new ideas.

And if you're curious about CRAFT itself — how a structured framework for AI communication can transform a creative workflow — stay tuned. That's a story worth telling too.

The Experiment Continues

Ketelsen.ai has always been about pushing the boundaries of what's possible with AI prompting. Version 1.0 proved the concept. Version 2.0 is building the system to take it further than any one person could alone.

This is still an experiment. But now it's an experiment with a framework, a process, and a memory that gets sharper every week.

Ketelsen.ai 2.0 launched in March 2026. The CRAFT Framework is developed by Ketelsen Digital Solutions LLC.
