AssemblyAI— Speech-to-Text API with superhuman accuracy
We offer a platform where users can give away their unused items for someone else. As a return for givers, they can select a preferred small gift(snack, pen, letter, etc) to be received from the receivers. The givers can also select to not receive anything.
Easing the buy and sell process is what we're about. There may be other platforms, but none as simplified and straightforward as ours. We want the buy and sell experience to be great for our users and want to hear back from them - to incrementally improve.
