The Sharpener and the Crutch

After months of building AI tools, the hardest lesson is the simplest one.

Most tools are not sharpeners. They are crutches.

A sharpener makes the blade better. You use it, you put it down, and the knife cuts deeper than before. The tool improved the thing and then got out of the way.

A crutch holds you up. You use it, and the muscle underneath gets a little weaker every day. Take it away and you do not walk better. You fall.

Every AI-powered tool on the market right now is sitting on that line. And the uncomfortable truth is that most of them have already crossed it.

I build AI systems for a living. SparkPad, Canvas, Halo, Satori — tools designed to collapse time, remove drag, and make professionals more capable. That is the mission. That is also the trap. Because the exact same architecture that makes someone more capable can, with a subtle shift in defaults, make someone less capable. The code is nearly identical. The outcome diverges by a single design decision: does this tool preserve the human's contact with the hard part, or does it quietly absorb it?

That is where every tool forks.

The sharpener version of a tool clears the admin so the human can spend more time on the part that matters — the judgment, the second-order thinking, the conversation, the hard call. It returns attention to the places where reality still has a vote.

The crutch version clears the admin and then keeps going. It starts handling the thinking, too. It summarizes the meeting so you never have to sit in the tension. It drafts the follow-up so you never have to process what actually happened. It recommends the strategy so you never have to feel the discomfort of not knowing yet.

And the person feels productive the whole time. That is what makes it so dangerous.

The crutch does not hurt. It soothes. It removes the friction, the confusion, the moment of not-knowing that used to force a human being to actually stay in the chair and think. It replaces struggle with fluency, and fluency feels like progress even when it is replacing the exact muscle you needed to build.

After enough time on the crutch, you do not notice the atrophy. You just notice that the tool feels essential. That without it, the work feels harder than it used to. That you are moving fast but trusting your own judgment less.

That is not leverage. That is dependency wearing a very well-designed outfit.

The sharpener is harder to build because it requires a founder to deliberately leave friction in the system. To resist the temptation to make the tool do everything, even when it can. To accept that the product will feel less magical on the demo but more valuable after a year of use. To optimize for the question nobody puts on a landing page: six months from now, is this person more capable or less?

That question is the whole game. It is the prosthetic test. It is the fork between tools that extend the human and tools that slowly edit the human out while keeping their name on the document.

Most of the market is building crutches right now. Not because they are careless. Because crutches are easier to sell. They produce immediate results. They look like leverage on a dashboard. They fit on a slide.

Sharpeners are harder to sell because their value is invisible in the first month and overwhelming in the twelfth. They require trusting the user enough to let them struggle at the right moments. They require building with the patience to let the human grow into the tool instead of just using it.

But sharpeners are what last.

The tool that makes you sharper is a tool that eventually becomes optional. Not because it failed, but because it did its job. It extended your mind until the extension became part of how you think. You can put it down and still cut.

The crutch that makes you dependent is a tool that eventually becomes a leash. You cannot put it down without losing something. And by the time you notice, the muscle is already gone.

The question for every founder, every leader, every person choosing a tool is the same.

Is this making me sharper, or is it making me need it more?

That distinction is the whole future.
