HAHA no one has asked me this.
I have this built out and hooked up to S3 I disabled it as I thought users wouldnt want it.
In the early days. I would use the webcam, record me talking. Then caption it on the spot, add some letterbox text and publish to my Instagram story.
I might have to reveal it and bring it back. This is of course if people want it and it solves a pain point worth paying for.
