👋 Hey Product Hunt! I’m Anth, a tabletop RPG GM who built GMprentice to solve a problem I kept running into: there’s nowhere to practise GMing without an audience. GMprentice lets you rehearse encounters, rulings, pacing, and roleplay with an AI adventuring party that reacts like real players, so you can experiment, fail safely, and build confidence before game night. I’d love your feedback, especially from GMs, players, and anyone curious about AI in creative tools. Thanks for checking it out! 🎲✨
