Going by the standard of "But there are also local tools generated faster than you could adjust existing tools to do what you want", here's a random one of mine that's in regular use by my wife:
https://github.com/TeMPOraL/qr-code-generator
Built with Aider and either Sonnet 3.5 or Gemini 2.5 Pro (I forgot to note that down in this project), and recently modified with Claude Code because I had to test it on something.
Getting the first version of this up was literally both faster and easier than finding a QR code generator that I'm sure is not bloated, not bullshit, not loaded with trackers, that's not using shorteners or its own URL (it's always a stupid idea to use URL shorteners you don't control), not showing ads, mining bitcoin and shit, one that my wife can use in her workflow without being distracted too much. Static page, domain I own, a bit of fiddling with LLMs.
What I can't link to is half a dozen single-use tools or faux tools created on the fly as part of working on something. But this happens to me couple times a month.
To anchor another vertex in this parameter space, I found it easier and faster to ask LLM to build me a "breathing timer" (one that counts down N seconds and resets, repeatedly) with analog indicator by requesting it, because a search query to Google/Kagi would be of comparable length, and then I'd have to click on results!
EDIT: Okay, another example:
https://github.com/TeMPOraL/tampermonkey-scripts/blob/master...
It overlays a trivial UI to set up looping over a segment of any YouTube video, and automatically persists the setting by video ID. It solves the trivial annoyance of channel jingles and other bullshit at start/end of videos that I use repeatedly as background music.
This was mostly done zero-shot by Claude, with maybe two or three requests for corrections/extra features, total development time maybe 15 minutes. I use it every day all the time ever since.
You could say, "but SponsorBlock" or whatever, but per what GP wrote, I just needed a small fraction of functionality of the tools I know exist, and it was trivial to generate that with AI.
