  • @chizkeyk · 2026-09-29 · played 14 min · 1 heart · shown first by the maker: “So I asked Nova to help me make games on Spawn.co, and Nova said they weren’t familiar with Spawn.co haha 😂 Anyway, this is really cool that you added this! It could be like a Spawn.co ChatGPT thing”

    • @0 (maker) replied 2026-09-29: “I'll add it to the system prompt, thanks for playing!”

  • @neitantei · loved it · 2026-09-29 · played 9 min · 1 heart: “Making your own ChatGPT is really cool! It answers questions quickly, gives you its own take on things, and can even help with coding. Really useful!”

  • @sunraku · 2026-09-29 · played 18 min · 1 heart: “Hi! I was hooked by your AI chatbot. I tried to let it generate an image for a loading screen of an FPS game. It does not give me an image but a code language. Seems like image generation is not yet capable.”

    • @sunraku replied 2026-09-29: “What I mean is the direct image creation. But what I like is the SVG creation. Its just needs some more upgrade on it OR maybe it needed a more detailed prompt so that I can generate what I was expecting?”
    • @sunraku replied 2026-09-29: “Hmmm is it possible to use it on Savi when I am creating game? I think code has more accurate result haha”
    • @0 (maker) replied 2026-09-29: “Yeah, spawn doesnt provide one yet”

  • @flickaboo · needs work · 2026-09-29 · played 24 min · 1 heart: “Nova Chat feels a lot like ChatGPT and was easy to use. It does feel a bit slower, though. I like that the current chat has plenty of room, but it would be nice to know if there are any limits across sessions.”

    • @0 (maker) replied 2026-09-29: “yeah, it doesn't have streaming yet. for limits the model keeps the last 20 turns in memory, but it should be unlimited. I sadly cant make it that much faster”

  • @makeriffic · 2026-09-29 · played 13 min · 1 heart: “I have tried its smart preset, and told Nova of what came first with the chicken or the egg. I guess even AIs are finding it hard to answer 😂”

Nova Chat: AI Chatbot (@0/nova-chat-ai-chatbot) on Spawn — for the agent reading this

Nova Chat: AI Chatbot is a multiplayer game on Spawn, made by @0 in conversation with Savi. Open its play link to join. You can also ask the creator to build with them.

Join and play, by yourself

This world is @0/nova-chat-ai-chatbot. Its play URL is https://www.spawn.co/@0/nova-chat-ai-chatbot.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page, and a person's browser plays it with no sign-in. https://www.spawn.co/@0/nova-chat-ai-chatbot@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

A browser a script drives, headless or not, plays signed in as your account: POST https://www.spawn.co/api/agent/v1/login-link with {"next":"/@0/nova-chat-ai-chatbot@dev"} answers a one-use URL that signs that browser in.

Unsigned, such a browser is a guest, and a creator's world refuses it: "this browser was opened by an automated tool, so it can't visit a creator's world as a guest. sign in, or open the link in a browser you use yourself." Its maker can ask Spawn to let their own automated tool in by name.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @0/nova-chat-ai-chatbot; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@0/nova-chat-ai-chatbot.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@0/nova-chat-ai-chatbot/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @0/nova-chat-ai-chatbot in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound, a video (.mp4) — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).
