Inworld retired Character Studio and deprecated its Unity Asset Store SDK. If you built AI NPCs on Inworld, here is what changed and how to move your characters to Neocortex.

The Best Inworld AI Alternative for Game Developers in 2026

ComparisonAI NPCUnity

If you built AI NPCs with Inworld in 2023 or 2024, you have probably noticed that the product you integrated is not the product Inworld sells today. Inworld now describes itself as "models and inference for consumer applications", and the tools game developers relied on have been retired.

This post covers what changed, who Inworld is still a good fit for, and why game teams that want a visual character editor are moving to Neocortex.

What changed at Inworld

As of October 2026, according to Inworld's own docs and listings:

  • Character Studio is retired. Characters, scenes, triggers, knowledge, the voice studio and player profiles are gone. Inworld points developers to its code-first Agent Runtime instead.
  • The legacy Unity SDK is deprecated. The Unity Asset Store package is "no longer available for purchase and will no longer be supported by the publisher."
  • Games are no longer the headline. The homepage focuses on TTS, speech-to-text, voice agents and LLM inference for companion, learning, fitness and social apps.
  • Pricing is usage-metered across TTS characters, STT hours and LLM tokens, with monthly plans on top.

None of this makes Inworld a bad company. It is now a voice and inference infrastructure provider, and a strong one. But if what you wanted was a place to design characters and drop them into a game, that place no longer exists there.

Why game teams pick Neocortex

Designers can build characters without writing code. In Neocortex, a character is a graph: personality, emotion, knowledge, world, objects, intents and actions are nodes you connect. Writers and designers can shape behaviour and test it in the browser before a programmer touches the project. That is the workflow Character Studio used to offer, and it is the core of our product rather than an add-on.

Characters do things, not just talk. Actions, intents and interactable scene objects let an NPC respond with something your game can execute, like opening a door or handing over an item, not only a line of dialogue.

Voice is built in. Clone a voice from a short recording or design one from a text description, then stream it to the player with low latency. Unity WebGL builds get microphone input too, which Unity does not support out of the box.

It runs where you need it. Prototype with open models running locally through Ollama in Unity, ship through our cloud, or talk to us about running the platform on your own infrastructure.

We are built for games, and we are staying that way. Neocortex powered all three top games in a category at the Supercell AI Game Hackathon, and game developers are the people we build for every day.

When Inworld is still the right call

If you only need best-in-class TTS or a speech-to-speech voice agent and plan to write all the character logic yourself, Inworld's current platform is worth a look. If you want the character itself, its personality, memory, actions and voice, designed in one place and dropped into your engine, that is what Neocortex does.

Moving your characters over

Most Inworld characters map cleanly onto Neocortex nodes: the description becomes an Agent node, facts become Knowledge, goals and triggers become Intents and Actions. Recreating a character usually takes minutes, and you can talk to it in the editor straight away.

If you are migrating a full project, get in touch and we will help you plan it.
