I've subscribed to Tango in the past and currently have a sub to Dubble, which works very well for basic documentation needs. I tried Stepsy and the process is very straightforward. Works perfectly in Chrome. I ran into an issue with the extension in a Chromium-based browser (Arc) and Sasha responded right away. I'd love to see more annotation tools going forward (probably on the roadmap) but right now, it's an awesome, quick way to create the steps in any process. As it grows, I'm hoping it replaces one of my subscriptions.
