Claude, Copilot, and making a good desktop app.

This year, even as Anthropic, Google, and others have challenged OpenAI’s model performance crown, ChatGPT’s lead as an end-user product has only solidified. On the Dithering podcast last week (paywalled), Ben Thompson called out an aspect of why this is:

I need someone to write the definitive article on why the ChatGPT Mac app is so good, and why everyone else is in dereliction of duty in doing these.

Gemini 3 is reportedly coming this week. […] And I’m looking forward to it. I expect it to be good. And it’s just going to have to be so astronomically good for me to not use ChatGPT, precisely because the [Mac] app is so useful.

A model is only as useful as its applications. As AI becomes multimodal and gets better at using tools, these interfaces are getting even more important – to the point that models’ apps now matter more than benchmarks. And while every major LLM has a mobile app, only three have a Mac app: Copilot, Claude, and ChatGPT.
