How to save text to Cardano blockchain:

Create and top up https://adaly.io wallet, and in the Settings change interface from Simple to Advanced.

Then:
Copy your text -> compress https://www.multiutil.com/text-to-brotli-compress/ -> convert base64 to base64url https://www.base64url.com/ -> then go to https://adaly.io/#send -> set checkbox "Add a note to the payment" -> type "#hmwyda wishlist" and paste your base64url string.
And send.

Features (or bugs):
adaly.io removes all non-latin characters and even "/" and "+" characters - that's why base64url is needed.
Minimum amount is 1 ada (approx 3 usd).

And base64url also removes "=" characters in the end, and in order to decompress https://www.multiutil.com/brotli-to-text-decompress/ you need to add "=" one by one until error disappears.

It looks complicated, but it is still easier than using command line cardano-cli.
