I have been using Affectiva's emotion recognition API for a while now, and it has been a game-changer. The API is easy to integrate and provides accurate results. The team at Affectiva is always prompt in addressing any concerns or questions I have. It has significantly improved the emotional analysis in my research projects. I am impressed with the level of detail and insights the API provides. Highly recommended!
