Mindforge

AI characters with personality

Create characters that have a name, a voice, knowledge, and capabilities. Use them in games, museums, apps, advertising — anywhere you need an AI that feels like someone, not something.

Quickstart

API reference

OpenAI compatible

Use any OpenAI SDK to talk to your characters. Point it at Mindforge and go.

Identity first

Every character is an AI agent with personality, voice, and knowledge. Not just an LLM wrapper — a someone.

RAG built in

Upload documents and your characters use them as context automatically. No vector DB setup needed.

Voice rooms

Multi-agent voice conversations powered by WebRTC. Characters talk to each other and to your users.

Tool calling

Characters call functions in your app. Define capabilities and they use them autonomously.

Works everywhere

Game NPCs, museum guides, brand mascots, app companions, training simulations — one API for all of it.
