Archie

Inspiration

A lot of kids have great game ideas, but coding and the overall complexity of building in Roblox can get in the way. We wanted to create something that makes game creation feel more approachable, natural, and fun for younger creators who may not know where to start.

What it does

Archie is a voice-first AI game-building assistant for Roblox. A user presses the Start Building button, connects Archie to Roblox Studio, and then talks through their game idea out loud. Archie helps turn that conversation into a clearer game concept and a more guided building experience.

How we built it

We built Archie with a React and Next.js frontend and a Node/Express backend. The frontend focused on creating a friendly, immersive experience with chat, voice interaction, and an animated avatar, while the backend handled the AI workflow and game-planning logic. We both helped across the stack, but I focused more on frontend and my teammate focused more on backend.

Challenges we ran into

One of the biggest challenges was getting the avatar system working the way we wanted, especially after Ready Player Me was discontinued. We also spent a lot of time figuring out the right AI workflow so Claude could help design Roblox games in a way that actually felt useful and natural for the user.

Accomplishments that we're proud of

We’re most proud of the overall game-building experience and how user-friendly it feels. We wanted Archie to feel welcoming instead of intimidating, and we’re happy that the final demo makes creating a game idea feel more accessible and interactive.

What we learned

We learned a lot about designing AI workflows for creative tools and how much structure is needed to make AI genuinely helpful. We also learned a lot about voice integration, especially syncing avatar speech with lip movements in a way that feels engaging and alive.

What's next for Archie

Next, we want to give users more ways to shape the kind of game they want to build. That could include templates, style presets, and more guided options so users can quickly choose a specific type of game and have Archie adapt its help around that direction.
