I found there to be no flow and kind of confusing as someone already using Nostr. It may be good for a newbie. I used the signer to complete the action of logging in and moving instagram posts to Nostr. I found it odd the my phone was playing music. When I tried to import from Substack, it started doing it but I wasn’t signed in, yet my phone was still playing music. Also, maybe give a direct link or how to find the Substack rss feed. Substack is bloated and it’s tedious to find that info in my Substack account. I googled it to save time. But then I needed to log into your tool all over again as it had done the import to a new npub instead of mine… so I gave up on Substack since I’d have to start over anyway.
