Ask HN: Would you be interested in a cross platform tool for password hints?

Hey HN, I've been working on a cross platform tool for saving password hints and wanted to get some feedback before launch (I guess I'm somewhat procrastinating putting the finishing touches on it and wanted to get some feedback). Idea Password hints, everywhere. Why? I created this project because I have a file on my computer that does the same thing, and wanted it everywhere. I don't (yet?) use a password manager, and don't use an everywhere-synced notes solution so I end up with disparate files on different machines with hints in them. Also some good ol' nostalgia for the hint box in some older OSes and password systems these days. Pricing I'm torn between $1 and $2 a month if you choose to have us host your hints (the clients & server will be open source so you can host your own for personal use). Where I am now At present, I've built the web app, chrome/ff extension, and electron close to finish (thanks to web tech), and am considering adding mobile apps. The app really is as simple as it sounds but I've built it top to bottom and worked on it on/off for a while. I also plan to support a chrome/ff extension that actually puts the hint box next to the password field. It creeps me out when extensions want to access all the content of pages (for modification purposes) of sites I visit, so this would be a separate extension of some sort. I wanted to make a landing page and collect emails to judge interest or something like that, but it seemed to "growth-hack"y (in the negative sense of the term), and something that people get annoyed by these days. Feedback I'd love - Would you pay for this? - Do you have this problem/some list of hints on your system? - Any ideas for increasing value - Anything else you've got to say
