AI RPG maker for playable top-down RPGs
Capybara turns an RPG idea into a structured plan first, then a build chat turns that plan into a playable game slice with maps, characters, quests, combat, HUD, and iteration hooks.

Make an RPG loop you can actually play
The real question is not whether AI can describe an RPG. It is whether you can get a playable role-playing loop with a map, a player goal, NPCs or enemies, interactable objects, and feedback that makes the scene feel like a game.
The planning agent asks high-leverage questions when the answer changes the asset slate or core loop. After the plan is approved, the chat agent coordinates assets and code so the first build follows the plan instead of drifting into a feature list.
RPG NPCs can be more than dialogue boxes
Capybara plans NPCs with jobs, patrols, post-work loops, dialogue states, quest flags, and optional AI memory. For an RPG, that means villagers can remember promises, suspects can react to evidence, and quest givers can change behavior after the player acts.
The builder brief keeps AI conversations grounded in game state — inventory, relationship values, discovered clues, objectives, and world events — so NPCs support the loop instead of becoming generic chatbots.
What Capybara can make first
Keep the first version small enough to finish and complete enough to play.
Plan first, then build with the chat agent
Start with a plain-language idea. Capybara may ask a few focused questions when a decision changes the first map, NPCs, mechanics, or player goal.
Once the plan is ready, approve the first playable slice. The build chat uses that plan as the source of truth, then you keep improving the game by asking for clearer feedback, stronger NPCs, better objectives, new areas, or more polish.
Start with a prompt, then refine
Use one of these as a first message, or rewrite it in your own words.
