Show HN: AI Audience Platform for Practicing Public Speaking

https://spuai.github.io
2•speakupai•2h ago
We are building a platform to solve a problem a lot of people are struggling with: how to practice public speaking when you have no audience.

Traditional methods are limited: practicing with friends is very limited(their qualification can be lower than yours, and you are limited in the amount of times you can practice), Toastmasters requires scheduling and gives you like 5 mins of speech per week(also limited in the amount of times you can practice), and speech apps just correct your spelling. Yet 77% of people fear public speaking, and most of them have no idea how to practice it.

Our platform lets you practice presentations in front of a customizable AI-generated audience without any limitations. You can practice as much as you want as often as you want.

Just start speaking and AI will simulate real audience: ask questions, etc.

We're in early development. Looking for brutally honest feedback from the HN community:

1. Does this approach make sense? 2. What specific features would make it actually useful? 3. Would you use this for preparing to your presentations/interviews?
