I was frustated by having to draw system design diagrams by hand when discussing it with my team mates or in an interview. So I thought Wouldn t it be great if someone draws it for me, while I think out loud? .That is when I came up with VoiceDraw. You can just think out loud or discuss your system architecture with a friend/interviewer, the diagrams are automatically drawn along with your reasoning, open questions and tradeoffs beautifully written on to the side.Demo Video: https://youtu.be/36PgHKSuccE
