  1. Foundations of Character Design and Conversational AI

    4 weeks
    Goals
    • Understand core character design principles from narrative design, psychology, and UX writing
    • Learn how large language models work at a conceptual level - tokenization, context windows, instruction following
    • Write your first system prompts and observe how personality emerges from prompt engineering
    Resources
    • Book: 'The Art of Character' by David Corbett
    • OpenAI Prompt Engineering Guide (platform.openai.com/docs)
    • Course: 'Generative AI for Everyone' by Andrew Ng on Coursera
    • Anthropic's guide to system prompts and constitutional AI
    Milestone

    You can design a basic AI character persona and write a system prompt that produces consistent personality across 20 diverse test conversations

  2. Prompt Architecture and Personality Engineering

    6 weeks
    Goals
    • Master advanced prompt engineering techniques - few-shot exemplars, chain-of-thought for character reasoning, role-based system prompts
    • Learn to use LangChain to build multi-step character response pipelines with memory and tool use
    • Study psychological personality frameworks and translate them into structured character schemas
    Resources
    • LangChain documentation and tutorials (docs.langchain.com)
    • Book: 'Wired for Story' by Lisa Cron
    • HuggingFace NLP course for understanding model fine-tuning basics
    • Research papers on persona-grounded dialogue generation
    Milestone

    You can build a LangChain-based character agent with conversation memory, personality constraints, and graceful fallback behaviors

  3. Testing, Iteration, and Multi-Modal Character Systems

    6 weeks
    Goals
    • Design adversarial testing frameworks to stress-test character coherence and identify failure modes
    • Integrate AI voice synthesis (ElevenLabs) and visual avatars (Ready Player Me, Live2D) with text-based characters
    • Learn to analyze conversation logs at scale and implement data-driven character improvements
    Resources
    • ElevenLabs API documentation and voice cloning tutorials
    • Inworld AI character engine documentation
    • Google's PAIR Guidebook for human-AI interaction design
    • Weights & Biases documentation for experiment tracking
    Milestone

    You can deliver a multi-modal AI character - with text, voice, and visual identity - that maintains personality coherence across 100+ test conversations including adversarial scenarios

  4. Production Deployment, Portfolio, and Industry Specialization

    4 weeks
    Goals
    • Build 2-3 portfolio projects showcasing AI characters for different verticals (gaming, customer service, education)
    • Learn production deployment workflows using AWS Bedrock, containerized pipelines, and monitoring dashboards
    • Develop a specialization focus - game NPCs, healthcare companions, branded agents, or virtual influencers
    Resources
    • AWS Bedrock documentation for LLM deployment
    • GitHub Actions for CI/CD of prompt-based character systems
    • Industry case studies from Character.AI, Replika, Inworld AI, and Soul Machines
    • Conference talks from GDC, CHI, and NeurIPS on conversational agents
    Milestone

    You have a polished portfolio with 3 production-quality character projects, a clear specialization narrative, and the ability to interview confidently for AI character design roles

Practice Projects

Apply your skills with hands-on projects. Ordered by difficulty.

AI Companion Character - Personality Prototype

Beginner

Design and implement a conversational AI companion character using OpenAI's API with a detailed system prompt. Create a character bible, write 20 sample dialogues, and build a simple chat interface that maintains personality across a 30-turn conversation.

Brand Mascot Chatbot with Guardrails

Intermediate

Build an AI character that serves as a brand mascot for a fictional company using LangChain. Implement conversation memory, a RAG-based knowledge base for product FAQs, and content guardrails that keep the character on-brand and safe.

~40h

Multi-Agent Game NPC System

Advanced

Design and implement a system of three interconnected AI NPCs for a role-playing game scenario using LangGraph. Each NPC has a distinct personality, relationship dynamics with the others, and reacts to player choices. Integrate with a simple game engine and include adversarial testing.

Character Consistency Evaluator Tool

Advanced

Build an automated testing framework that evaluates AI character consistency across hundreds of conversations. Use an LLM-as-judge approach to score characters on personality traits, tone, factual accuracy, and boundary adherence, with results tracked in a dashboard.

~35h

Voice-Enabled AI Character with Emotional Adaptation

Advanced

Create a voice-based AI character that detects user sentiment and adapts its tone and response style accordingly. Integrate Whisper for STT, a LangChain character agent with dynamic prompt injection, ElevenLabs for TTS, and test across diverse emotional scenarios.
