I have a better suggestion, which will save time, energy, money, and human work.
Don't.
Write it yourself. If you can't, don't post.
Just using your browser's built-in proofreader is enough in 99.9% of the cases.
Using ChatGPT to rewrite your ideas will make them feel formulaic (LLMs have a style and people exposed to them will spot it instantly, like a code smell) and usually needlessly verbose.
Or as ChatGPT would put it:
Precise grammar and spelling are undeniably important, but minor imperfections in English rarely obstruct communication. As the most widely used language in the world, English is highly flexible, and most people navigate small errors without issue. For the majority of cases, a browser’s built-in proofreader is entirely sufficient.
On one hand, tools like ChatGPT can be valuable for refining text and ensuring clarity. On the other hand, frequent reliance on such tools can result in writing that feels formulaic, especially to those familiar with AI-generated styles. Balancing the benefits of polished phrasing with the authenticity of your own voice is often the most effective approach.
Really - your comment on its own is good enough without the LLM. (And if you find an error, you can always edit!)
If we really wanted ChatGPT’s input on a topic (or a rewording of your comment), we can always ask ChatGPT ourselves.
You’d assume people would use tools to deliver a better and well composed message; whereas most people try to use LLMs to decompress their text into an inefficient representation. Why this is I have no idea, but I’d rather have the raw unfiltered thought from a fellow human rather than someone trying to sound fancy and important.
Not to say I still find the 20% claim a little suspect.
