Looks like an interesting service for sure in the form of a browser extension. I guess my first question would be, are you validating it to raise capital eventually? Do you need capital now to ultimately create it? From the sounds of it the best way to validate it if you have the option is to create it and have people use it.

If you don't have that luxury, is there a way you can validate it manually? Sounds like a stupid question but sometimes you might be able to validate an idea through manual means first then develop the technology around the process to replicate the result automatically. Hope that helps!
