What Replica Studios does well
Replica was one of the first AI voice companies built for games, with licensed AI voice actors, Unity, Unreal and iClone plugins, and the first SAG-AFTRA agreement for AI voices in games.
Why teams switch
Why game teams choose Neocortex over Replica Studios
Voices back fast
Clone from ten seconds of audio you have the rights to, or design a voice.
NPCs that talk back
Players speak; characters answer in their own voice.
Visual editor
Give every voice a personality, knowledge and actions.
WebGL voice
Microphone input in Unity WebGL builds, which Unity lacks by default.
Less lock-in
Prototype locally with open models; self-host the platform for studios.
Commercial use
Included on the Pro plan and above.
How it works
Characters you design, not prompts you babysit
- Personality, emotion, knowledge and world are nodes you connect, not prompts you rewrite.
- Intents and actions turn what a player says into something your game does.
- Test every character in the browser for free before it reaches your engine.
