I tried it out quite a few months ago, so I am only speaking to the initial version, but you created a timeline of JS events (tooltips, other tutorial/intro elements) with synced voiceovers (if you wanted) and it would show up on the user's end with a video player-esque UI so they could navigate the experience. The front-end was clean & simple, and I really liked it in theory (I disagree with the notion that any app that needs a walkthrough is broken by design), but the version I tried's backend wasn't created for people who couldn't sink some time into the JS and would have benefitted greatly from a more user-friendly approach.
