Show HN: Open-sourcing a Character AI-style app with TikTok-style video replies

https://github.com/stefanionescu/llm-roleplay-webapp
2•dr__stoney•8mo ago
This was a solo project I built over a couple months. It's an experiment mixing Character.ai with TikTok-style videos. Characters respond with messages and video “memories” pulled via RAG from a video database.

I tested this with a bunch of students and realized the idea wasn’t sticky enough to justify continuing, so I’m pivoting. But I figured others might benefit from the code or learnings.

The repo includes virtualized chat + session history, short-form video integration and video autoplay, internationalization, Supabase setup, Mixpanel analytics and lessons on why the format didn’t quite work (in the README).

Happy to chat if you're building weird stuff in AI/consumer.
