I have been messing around with creating a homoglyph keyboard for Android, but I’m wondering if it’s even worthwhile. Is there any benefit to masking your messages with homoglyphs? Primarily I think it could defend against an LLMs ability to easily scrape messages. In my experiments ChatGPT and DeepSeek both get confused by homoglyph messages unless you instruct it to determine the likely alphabet characters and numbers for each individual character.

This might fool some scrapping, but at the expense of making it not very legible for humans too. Also while ti might work right now, if it ever became a popular approach the AI scrapping could easily adapt. I expect they already try to correct for spelling mistakes anyway.
It reminds me of leet-speak. The custom keyboard is not a bad idea though.
