🎮 What you see in the video

Talk to anyone, even in old games

In a Pokémon FireRed fan mod, the trainer answers whatever you type, accepts or refuses your bet, and the battle really starts.

A sentence becomes a room

In a Binding of Isaac mod, describe a room and you fight in it. A wish becomes a real item, with real stats.

A village that remembers

Do something terrible. Everyone saw it, word spreads, and a ten-year-old won't let it go.

A suspect who cracks

Show him the evidence: his trust drops, his story changes, and he confesses.

Type it, it's built

"a lighthouse made of cheese" → it appears on the island.

⚙️ How it works, in 3 steps

1. Your game asks for something, with an example of the answer.

Kinloom.create("an item found in a cave",

{"name": "Glowcap", "value": [1, 50], "story": "Found under a cold stone."})

The example says: I want a name, a value between 1 and 50, and a short story.

2. Kinloom asks the AI, then checks the reply.

Wrong shape? Number out of range? An action your game doesn't have? Refused. Your game only ever receives answers that fit.

3. If there's no AI, the example is the answer.

No key, no internet, a slow model: your game gets your example (or your own lines) instantly. It never freezes, never crashes.

chat: a real conversation with a character, streamed, in about 1 second
say: a line when something happens (a kill, a goal, a sunset), instantly
decide: a choice or numbers, every frame, instantly
act: the AI uses your game's own functions (give an item, open a door, start a fight), and only valid calls get through
create: content of any shape (items, quests, levels, names, dialogue trees)
event: who saw what, so rumors spread and characters hold grudges
Voice: characters can speak and listen, with the system voice when there's no key

NPCs you can really talk to: shopkeepers you haggle with, companions who remember your choices
Quests and items made on the fly, in the exact format your game needs
A game master that builds the next room, wave or level from how you play
Rivals and enemies that pick a strategy every frame: attack, block, flee
Detective and interrogation games where suspects lie, remember and crack
Living towns where people gossip, have opinions and remember what you did
Commentators and announcers that react to the actual match
Mods for games that already exist: add AI characters to a game you didn't make

Engines: Unity, Godot, JavaScript, C++, Rust, Java, Lua, Python
AI models: Claude, OpenAI, DeepSeek, Gemini, OpenRouter, Ollama, LM Studio… or none at all
No dependencies: one file to drop into your project
Ready to ship: a relay keeps your API key off players' machines, with rate limits and spending caps

pip install kinloom

cd your-game

kinloom init

kinloom init finds your engine, adds Kinloom, and teaches your coding agent (Claude Code, Cursor, Copilot, Gemini CLI…) how to use it.

Then just ask in plain words:

▎ "Add a blacksmith I can talk to, who gives items to people she likes."

It picks the right calls and wires everything.

Coding agents wrote working code 88% of the time with Kinloom, vs 8% without
Replies start in about 1 second, for about $0.0005 each
45 attacks on a character's secret (prompt injection, fake authority…): the secret was kept

I'd love to hear what you'd build with it!
