I've been thinking about this and while it's true that I have been trying to find a viable subscription model for my business over the last couple of years, that's not really important for you.

But it does benefit you in a very real way.

I work alone. I'm very good at spinning up features in a few hours. With a subscription model I can release these changes continuously, so you get new features and improvements on a weekly or monthly basis.

If I had to come up with a release schedule I'd have to make a lot of decisions about cordoning off different features, coming up with names, marketing materials, deciding what goes where. This is a huge mental and technical overhead. I'd be juggling git branches across multiple pieces of software, the website, and beyond. I'd be incentivised to put more and more things behind the next paywall and I'd be getting less and less real work done.

I don't have the marketing clout of Apple or Microsoft. They can take a different approach. I've tried a few and now I'm trying this!

One more thing, I do plan on adding some more cloud-based features as time goes on. I'm already managing a Chat GPT integration, and in future I'm picturing an online content library and search to let teams quickly access decks and slides for demos. But that's future stuff, so not relevant to your question just now.

Short answer: it lets me, as a solo developer, give you more cool stuff.
