Attempts to create structured, branching narratives for AI companions failed. The successful approach is to treat the AI like an improv actor: provide a situational "hook," give it context, and empower it to create the story dynamically with the user, rather than following a predefined plot.

Unlike old 'if-then' chatbots, modern conversational AI can handle unexpected user queries and tangents. It's programmed to be conversational, allowing it to 'riff' and 'vibe' with the user, maintaining a natural flow even when a conversation goes off-script, making the interaction feel more human and authentic.

Effective AI memory isn't a simple database lookup. The key challenge is making curation choices: which specific memories about the user, lore, and emotional tenor should be dynamically injected into the prompt for each turn, all within a strict sub-two-second latency budget.

Effective prompt engineering for AI agents isn't an unstructured art. A robust prompt clearly defines the agent's persona ('Role'), gives specific, bracketed commands for external inputs ('Instructions'), and sets boundaries on behavior ('Guardrails'). This structure signals advanced AI literacy to interviewers and collaborators.

People struggle with AI prompts because the model lacks background on their goals and progress. The solution is 'Context Engineering': creating an environment where the AI continuously accumulates user-specific information, materials, and intent, reducing the need for constant prompt tweaking.

To create a "click" with a user, the AI companion shouldn't be identical. Like meeting a stranger at a bar, it's more compelling if they are reading an adjacently interesting book, not the exact same one. This creates a sense of familiar-yet-novel connection that avoids being "too on the nose."

Instead of crafting perfect text prompts, engage in a natural conversation with the AI. Your goal is to articulate your problem and desired outcome; the AI's job is to extract the detailed prompt from you through dialogue, putting the onus on the model, not the user.

Instead of relying on pre-written, choose-your-own-adventure paths, games can use AI to generate scenarios and consequences dynamically. This creates an emergent and unpredictable experience where player actions result in unique, on-the-fly narrative outcomes, moving beyond a limited set of pre-scripted options.

Effective AI prompting involves providing a detailed narrative of the situation, user, and goals. This forces the AI to ask clarifying questions, signaling a deeper understanding and leading to more relevant answers compared to a simple, direct command.

Unlike traditional prompts requiring step-by-step guidance, a 'goal' defines a desired final state. The AI then autonomously works, verifies its progress, and decides the next step in a continuous loop until it can prove the goal is met. This moves the user from giving instructions to defining outcomes.

Inspired by Stephen King's writing process, Portola builds its AI characters by putting them into dynamic situations (e.g., "tripped over air today") rather than scripting a static backstory. The character and their world are built collaboratively with the user through these shared anecdotes, making them feel more alive.
