This is fantastic, congrats. Have you ever thought of building a SaaS around this? Getting users to pay $5 a month for each specific service. It could be even more intuitive....
Yes, have thought deeply about this. There is a $19/month option for those who can't afford the lifetime price as it now. And that would include all the tools too when I add more paid tools.
The "SaaS" I would do is make paid versions of the google sheets add-ons and more work on Asa, the AI inside of Google Sheets I made. Right now it's free to use with your own API KEY but I'm working on a paid version.
