As a non-technical founder, I decided to take matters into my own hands and started to build the MVP myself. I had mapped out some rough sketches for how I thought the simplest version of the product could work.
I then decided to get to work in Bubble - through completing their tutorials and watching loads of YouTube videos, I've been able to build an MVP in Bubble.
Whilst it is a web-app that works on Desktop rather than a Chrome Extension, I believe that what I've built sufficiently replicates how mindreps will work.
