Hey everyone,

I’m Shay from Studio Erza. This is a free tool I'm actively developing that gives game jam participants a simple environment to structure and scope their project.

GDD Wizard is a browser-based tool built for jam teams to plan, organize, and finish stronger.

Key features:

• Jam-Focused Template - quickly outline your concept, core loop, roles & scope so you can spend more time building than planning.
• Export to PDF & JSON - share your design doc with your team, or attach it to your submission if you like.
• Multilingual - Translations for Spanish, French, Portuguese, German, and Czech.
• Open Source - Hosted on a GitHub Pages website. Repo can be found on GDD Wizard itch page.
• Quick Setup - no install required, no sign-ups. Just open, fill in the prompts, and start building.

Try it out here: https://studio-erza.itch.io/gdd-wizard

Any kindof feedback (Bug Reports, Feature Requests, Ratings & Reviews, etc) is greatly appreciated. Best of luck with your projects!
