I'm Dyslexic and so also lack confidence in my writing. LLMs are transformative for people like us, if they had been around when I was at school it would have been an incredible experience.

I can also completely understand the motivation to use it on HN, when I make mistakes in my comments, stupid ones like using the wrong word, and then get called out it hurts.

Chin up, you built a useful tool!

If you just used it as translation service then I see no need to even bring it up, but if you wrote three lines of actual information and had a computer expand that to three paragraphs of text then it should be common courtesy to disclose that people are wasting their time reading the added boilerplate

Would you mind sharing the prompts? My writing skills are horrible and I'm thinking about using LLMs to improve myself.

You could add “write this in the style of an ‘Show HN’ submission” to the prompt.
