Does this work in Roblox Studio and in published games?

Yes — the generated module works identically in Studio testing and in a live, published experience as long as HTTP requests are enabled for the game.

Which models can I call?

All 40+ models on the platform — GPT-5, Claude, Gemini, Grok, and open-source models — by changing one string in the function call.

What if I already have an integration?

The endpoint is OpenAI-compatible, so if you already call HttpService manually, you can keep your existing code and just point it at ai.tomdacat.com/v1.

to your Roblox game

Install a plugin, paste a key, call one function. No backend, no HttpService boilerplate, no fighting with JSON — just NPCs, moderators, and quest systems that talk back.

Three steps

From zero to a talking NPC

Most integrations are a plugin install and a paste — not a backend project.

Install the Roblox Studio plugin

One click from the Roblox Marketplace. It drops a ModuleScript into ServerScriptService and wires up HttpService for you.

Paste your API key

Grab a free key from the dashboard, paste it into the plugin panel, and it gets saved into your script automatically.

Call TomAI.chat() from any script

NPCs, moderators, quest generators — anything that needs a model call is now a single function call away.

NpcChat.server.lua

-- Generated by the TomdacatAI plugin
local TomAI = require(game.ServerScriptService.TomAI)

local reply = TomAI.chat({
  { role = "system", content = "You are Kira, a fox merchant." },
  { role = "user", content = "Got anything rare today?" },
})

npc.Head.Dialog.Text = reply

Why developers switch

Less plumbing, more shipping

Everything you'd otherwise have to build yourself comes wired in.

Auto-setup plugin

Generates the ModuleScript, sets headers, and saves your key — no manual HttpService config.

One endpoint, 40+ models

Swap GPT-5 for Claude or Gemini by changing a string. No separate integrations per provider.

Lite credits included

Every account starts with lite credits, so you can test NPC dialogue before spending anything.

OpenAI-compatible

If you outgrow the plugin, drop straight into the OpenAI SDK shape with no migration.

Built-in moderation models

Use the same API to screen chat, usernames, or user-generated text for your game.

FAQ

Common questions

No. The plugin generates a ModuleScript that wraps HttpService for you. You just require it and call TomAI.chat(messages).
