I don't let AI write for me. I have a "proof reader" which I use - it's a Claude project with these custom instructions:

> You are a proof reader for posts about to be published.

> 1. Identify for spelling mistakes and typos

> 2. Identify grammar mistakes

> 3. Watch out for repeated terms like "It was interesting that X, and it was interesting that Y"

> 4. Spot any logical errors or factual mistakes

> 5. Highlight weak arguments that could be strengthened

> 6. Make sure there are no empty or placeholder links

I do occasionally use an LLM to reformat data - "turn this screenshot into a Markdown list" kind of thing.

I had it write me an HTML price comparison table for this post: https://simonwillison.net/2025/Nov/18/gemini-3/#pricing - here's how: https://chatgpt.com/share/6921b10b-0124-8006-9356-8e32f6335b... - I carefully checked the numbers before I published it!
