Visualisation of prototypes before testing on users with easy access across multiple devices. - No need for coding;- Ability to test different scenarios at once.- Very cost efficient (lowest in market)- Great tool! Nothing significant i dislike about it so far though would love if they make additional features live easily like using API's from external service provider or integration into 3rd party system. This can be solved by developing customised plugins but will require some programming skills which may not exist within team / budget constraints etc.. Would recommend this as great starting point for prototyping conversations/flows. Conversations between customers and B2C clients where to gain insights are mostly where we use voice flow the most right now. The best part of voice flow was that we could create prototypes in minutes instead months or years like other tools out there! It's not perfect but it does what its supposed too which should be enough for most small businesses/startups needs at this point (also I think they are making improvements). We used VF when prototyping an app with our customers so their feedback would help us iterate faster than if using traditional methods such as wireframes / mock ups etc..
