Writing.

I've tried for years to build writing tools with AI. I think for the most part, it doesn't work well and they have become worse (more unnatural) since GPT-3, with the exception of GPT-4.5 and Gemini 1.5 Flash.

There are bits you can delegate to AI: Writing punchy intro paragraphs. Brainstorming titles. Starting off dialogue in a certain style, but it can't sustain it for very long. Or dialogue as another person - you often don't want two characters with similar language.

Writing is thinking. You can rubber duck it for ideas. And it does bounce back some good ones. But you can't expect it to do the heavy work.

Lately, I've been reversing the dynamic - getting AI to generate the bullet points while I write the document. The last straw was when I got it to summarize a doc, and then got it to do work based off the doc it wrote. It would get half the work wrong.
