Very nice work! I've written a small API (https://m8.fyi/chord) to generate beautiful diagrams easily and quickly from Python. It's definitely not making a living from the income, but it is enough for a coffee every now and then.
Nice, cool idea. Is that a one-time fee or monthly? If one-time then I'd suggest emphasizing that fact and saying something like "lifetime access" (from my experience most people assume monthly for something like this). Also fyi, your PayPal button does nothing when I click it. Best of luck with everything!
Thank you for the great suggestion - I've already updated the page to add "Lifetime Access"!
Fixing the Paypal button issue will be more tricky! I just tried it in Firefox and it's fine, but I'm seeing temperamental issues in Safari. Will look into it further - thanks for the heads up.
