This looks really interesting. If I build an app with this do I have to use your REST web api, or can I download the results of my expert system creation somehow and integrate it into my app, making it entirely off line?
I'm one of the co-founders in this project. Thanks for taking a look at Rainbird.
Currently to integrate you'll either need to use our REST api or a Javascript agent - essentially a little themeable widget you can embed in your site. This means that we host your knowledge base and you need do to be on-line to access what you've built.
We do have plans to provide a version of our engine that could be used off line or self hosted. Although we don't expect this to be available in the near future.
We’re big fans of open source and have already released one of the components on GitHub (https://github.com/rainbirdai). We have plans to release more things over the coming weeks and months.
