Science Rockstars aims to transcend simple recommendation engines and A/B testing techniques to create personal profiles of pitches that persuade individually. Their Persuasion API allows applications to compile profiles of each customer and what sways them.

The documentation notes that it can be implemented either on the server or client side (the latter includes a Javasctipt library to facilitate the process).
