Neocortex Unity SDK

Bring the characters you build on the Neocortex web platform into your Unity game: characters that talk, listen, act on the world around them, and hold a conversation with each other.

Full documentation: docs.neocortex.link

What it does

• Talk and listen. Text or voice in, text or voice out. One microphone component that works on desktop, mobile and WebGL, permissions and device selection included.
• Replies with delivery. Every reply arrives as ordered chat lines, each with its own emotion, so you can pace them, animate per line and voice them separately.
• Actions. Characters trigger the action keywords you author, each carrying the entity it applies to, so one reply can act on several things in order.
• Perception. Tag objects in your scene and characters sense them, reason about where things are, and act on the one you meant.
• Group scenes. Several characters in one shared conversation with an AI director deciding who speaks, plus a roster that can change while the game runs.
• A complete chat UI. Panel, avatars, inputs and indicators, scaffolded into your scene in one click.
• Usage aware. Read your plan, credits and per player limits, and gate features before spending anything.
