I was getting stuck in some manager <> direct report situations and wanted to figure out a way to practice tough conversations, so I started putting together https://practicecallai.com/.

You can choose from common difficult scenarios or create a custom one and get connected with a conversational AI voice agent to practice. Started out with just manager use cases but now testing out sales calls, interviews, pitches, etc.

Mostly built on Replit (would recommend - is amazing & keeps getting better) and relying on a mix of ElevenLabs / OpenAI / Anthropic for the voice & LLM tech.
