If you've ever tried to name a project, you know the routine. You think of a name, type it into a registrar, and get told it's taken. You try a variation. Taken. You add "get" or "try" or "app" to the front. Taken, taken, taken. An hour later you're staring at a list of names you don't actually like, picking the least bad one.
We hit this exact wall while naming one of our own side projects, and decided it was worth fixing properly. The result is dotnotfound.com — a free tool that does the brainstorming and the checking for you.
How it works
You describe your project in plain English — what it does, who it's for, the vibe you're going for. Claude generates a handful of naming directions, each with around 20 candidate names, split into tiers by how likely they are to be available.
From there you pick the directions that feel right, and dotnotfound checks every candidate live against the domain registries (using RDAP, the public domain registration protocol). Results stream in one at a time, so you watch availability get checked in real time instead of waiting on a spinner.
If nothing quite lands, you can tell it what you liked or didn't, and it generates a fresh batch — avoiding everything you've already seen. It's a loop you can run as many times as you need, until something clicks.
Who it's for
Anyone naming something new — a side project, a small business, a product. No account required, and the available domains link straight through to registration. It's free to use.
Why we built it this way
This is the kind of project we like working on at Island AI Lab: a real, specific frustration, solved with a tool that's simple to use and doesn't try to upsell you on the way through. It's also a good example of what "Build" looks like for us — scope a real problem, build something that works, ship it.
Free, no account needed. We'd love to hear what you think.
