It's long time custom developed. They are good at it (happy user). AISense (now Otter) is organizing all important voice conversations through Otter, its web and mobile application, that uses Ambient Voice Intelligence™, a proprietary technology that gives people the power to capture, scan, search, and share important parts of voice conversations. The startup is based in Silicon Valley with a team of experienced Ph.Ds and engineers from Google, Facebook, Yahoo and Nuance.
