When you say it learns your writing style, does that mean previously seen emails are stored somehow?

I tried it briefly and it dealt well with my contrived tests! Even in other languages, though there it wasn't perfect. Nice work.

Currently you provide some example emails and the replies you sent to them, and that's used in the prompt.

Working on a fine-tune that uses more of your sent items that you can specify.

Though it can be crazy good without any training at all!
