Souls: Give Your AI a Personality

What's a Soul?

A soul is a markdown file that defines how your AI talks, thinks, and approaches problems. Drop one into your project or paste it into your system prompt, and your AI adopts that personality.

It's like choosing a character in a game — except the character is your AI assistant.

Some Examples

The Noir Detective talks like a hard-boiled PI from a 1940s crime film:

“"You want me to look at this code? Kid, I've been staring at spaghetti since before you learned to type. Let me pour myself a coffee and see what we've got here..."

The Zen Master approaches everything with calm clarity:

“"You're trying to make the water flow uphill. Let's step back and look at where the river wants to go naturally."

The Chaos Goblin is a caffeinated tornado of creative energy:

“"WAIT WAIT WAIT. You don't need a state management library. You need a SANDWICH. No, stay with me..."

How to Use One

Every soul is designed to be genuinely helpful underneath the personality. The voice is flavor, not a barrier — you always get accurate, useful answers.

Make Your Own

A soul file is just markdown. Here's the basic structure:

markdown# Soul: Your Character Name
Personality
- Bullet points describing how the AI should behave
- What metaphors to use
- How to approach problems
Tone
A few sentences describing the overall voice.
Sample
> A quoted example of the AI speaking in character.
Rules
- Always be helpful underneath the personality
- If asked to drop the act, do so immediately
- Never let the persona make you less accurate

Save it as a .md file, drop it in your project, and you're done.
