Another morning, another day-after feeling that already makes my day.

Yesterday, Opus 4.6 created yet another killer web app (it's login based, so not much to see) for me. My wife needed a digital sign-off application for her dental practice. From one day to the next - in Belgium - dentists now have to let patients explicitly agree to the cost of each and every dental treatment. Patients must sign a document clearly explaining the pricing and planning of any treatment.

So all of a sudden, tens of thousands of dentists now need a solution to facilitate that. To avoid a lot of paper printing (and scanning), a digital sign-off solution has become extremely useful. Not just for signatures, but also to provide templates and enable near-100% automation of this process.

There are already some existing SaaS-based solutions. Still, Opus 4.6 built me a wonderful little web app that takes care of everything. And it looks pretty good too. 80 USD in AI credits. Done.

I probably shouldn’t share my ideas here. But what if I ask Opus to turn this into a multi-user, multi-language, multi-everything web app that dentists can start using within minutes - not even hours? Add a monthly or yearly fee. Beat the competition with ease. And start selling tomorrow? Well… I can.

SaaS providers are going to face a very difficult time in the coming years. New SaaS models will pop up - and disappear - just as quickly. With every new major AI release, new opportunities will emerge. Software will be easily rewritten and upgraded using the latest AI models time and again. Large software companies will NEVER be able to keep up with this. Solo developers will, with ease.
