AssemblyAI— Speech-to-Text API with superhuman accuracy
Founded by Zöe Sugg (Zoella) and sisters Elsie Larson + Emma Chapman (A Color Story, A Beautiful Mess), Filmm is a new effects and filter app, allowing users to add authentic film textures, light effects, and VHS distortions to any video clip.
Randy allows you to start making selfies and applying filters, but with the only difference - all the filters are generated randomly, so each is unique... literally. It is very fun when you never know what you’ll get, but the result might be really cool!
