An AI that knows who it's talking to.

A personal AI profile is the short list of facts Syntrofos should know about you before the conversation even starts.

Most AI apps begin every chat the same way: "Hi! How can I help you today?" That works for a search box. It doesn't work for a companion. A companion should already know who it's talking to.

That's what the personal AI profile is for. It's the difference between starting a conversation cold and starting one in the middle.

What's in your personal AI profile

The profile is intentionally small. Big AI profiles become a tax — you spend an hour customising, then never touch it again. Syntrofos keeps the basics easy to set and lets the long-term memory layer do the rest.

The basics:

• Your name and how you'd like to be addressed.
• Pronouns, if you want them known.
• A short note about you — a sentence or two. "I'm a software engineer who lives in Brooklyn and is trying to read more." That kind of thing.
• The people in your life — names and relationships. "Sarah, my partner. Mom, lives in Ohio. Daniel, college friend I talk to weekly." Syntrofos uses these to resolve mentions in conversation.
• What you care about — three or four topics that come up a lot. Work, fitness, a hobby, a side project.
• What you don't — topics you'd rather not discuss, or want the AI to handle carefully.

That's it. You can add more, but most people stop here, and the AI fills in the rest from how you actually talk.

Why this changes the conversation

Without a profile, an AI has to learn who you are from every conversation. With one, the AI starts every conversation already knowing:

• How to address you
• Who's "Sarah" when you say "Sarah said something weird today"
• That you mentioned you're trying to read more, so book recommendations land
• That fitness is a recurring topic, so check-ins about it feel natural
• That you don't want to talk about a specific topic, so it doesn't bring it up

It sounds small in bullets. In practice, it's the difference between talking to a chatbot and talking to someone who's been listening.

The profile and the personality

The profile and the personality are different things, and they work together:

• Profile = facts about you
• Personality = how the AI talks

You can have the same profile across multiple personalities — your facts don't change when you switch from Friend to Motivator. But each personality uses the profile differently: a Motivator uses your goals; a Listener uses your mood.

Syntrofos keeps these separate on purpose. Conflating them is how you get a chatbot that confuses who you are with how it should talk to you.

Multiple profiles per device

If you share a device — a family iPad, a partner's iPhone — each person keeps their own profile. Switching profiles switches the AI's memory, personality, and history. Nothing leaks across.

Some people also use multiple profiles for themselves: one for work, one for personal. The work profile can be tuned to the kind of conversation that helps with tasks; the personal profile can be the friend you talk to at night. The two don't have to know about each other.

What the profile doesn't do

A few things we deliberately keep out of the profile:

• No mental-health flags. Syntrofos is not a therapist. The profile is for context, not for diagnosis.
• No location tracking. Syntrofos doesn't need to know where you are to have a good conversation. If a feature ever needs location, it asks first.
• No demographic profiling for ads. The profile is for your AI, not for sale.

The profile exists to make the AI feel personal to you. We protect that by keeping it private.

How to set it up

Setting up the profile takes about two minutes:

1. Open Syntrofos and tap "Set up your profile."
2. Fill in the basics — name, how to be addressed, a sentence about yourself.
3. Add the people who come up most often.
4. Pick the topics you care about and the ones you'd rather avoid.
5. Done.

You can edit the profile at any time. Changes apply on the next conversation.

What you get for two minutes of setup

After the profile is set, the small frictions of talking to an AI mostly disappear:

• The AI calls you what you want to be called.
• The AI knows who you mean when you mention people.
• The AI brings up topics you actually care about.
• The AI avoids the topics you don't.
• The AI uses the tone you've set as your default.

That's the whole point. A personal AI should feel personal. The profile is how Syntrofos starts being yours.
