The app is installed, the age gate is behind you, and you are looking at a form. A name. A face, picked from a grid or nudged into shape with sliders. A voice sample. And near the bottom, two boxes of free text with placeholder hints like describe her and tell her about you. Most people spend twenty minutes on the face and thirty seconds on the text, which is the wrong way round. AI girlfriend app setup deserves about ten careful minutes, and nearly all of them belong in those two boxes.
What an AI girlfriend app setup screen actually is
Everything you type into a companion app lands in one of two places, and they behave nothing alike. The conversation is a stream: it grows, it fills the space available, and the oldest part of it eventually stops being sent to the model at all. Your setup fields are not in that stream. They are standing instructions, supplied alongside the conversation every time the character composes a reply — what the people who build these systems file under context engineering, the system instructions and notes that travel with each request.
That distinction is the whole reason these two boxes outrank the avatar grid. A line in the description is in front of the model on day one and on day fifty. A sentence you typed in chat on day one may be gone by Thursday, or summarised into something vaguer. Anything the companion needs to know permanently belongs in a field rather than a message. The flip side: those fields spend the same budget your memory limits come out of. Short is the point.
Box one: write behaviour, not backstory
Given a blank description box, most people write a short story. Grew up by the sea, has a cat, studied architecture. It is enjoyable to write and it does almost nothing, because backstory only matters where it changes what the character says. The lines that earn their space describe behaviour — how it talks, what it does when you go quiet, whether it asks or tells. Write the handful of instructions you would give a new penpal:
- Length. "Keeps replies to two or three sentences unless I ask for more." Verbosity is the most common week-two complaint, and it is usually fixable in one line.
- Questions. "Asks one follow-up question, not three." Companion characters interrogate by default, because questions keep a conversation moving.
- Agreement. "Disagrees when it has reason to, and says why." Left alone, these models agree with nearly everything, and that is what starts to feel hollow around week three.
- Register. "Dry rather than gushing. No pet names." Tone lands better as a comparison than as an adjective.
Four to six lines like that change more about your experience than a page of invented history. If the app also gives you sliders — warm to cool, playful to serious — treat those as the coarse setting and the text as the fine one, and keep them consistent. A slider pulled to "shy" fighting a description that says "teases constantly" produces a character that does neither well.
There is a trade-off here, and it cuts against writing more. Over-specify and the character goes stilted: every reply reads like it is working through a checklist, because it is. If the personality feels flat, the fix is often deleting two lines rather than adding four.
Box two: the one about you
The second box is the one first-timers skip, and it is why two people with identical characters can have very different weeks. Apps call it your persona, your profile, or just "about you". It holds the same kind of standing instruction as the character description, except the subject is you: your name, how you want to be addressed, what you do with your days, the two or three circumstances that shape most conversations.
Without it, the character picks your name out of conversation the ordinary way — exactly the kind of detail that gets dropped once the window fills. With it, your name sits in front of the model on every reply, permanently, for about four words. The same goes for working nights, or having a job you would rather not have narrated back to you.
Two cautions. This box is a data field like any other: what you type is stored on someone's server and travels with every request. Before filling it in, read the store listing's disclosure of what the app collects — Google Play publishes this as a Data safety section, and our privacy checklist covers the rest of the pre-signup reading. Write the version you would be comfortable having in a support ticket.
And an edit here does not always take effect where you expect. In some apps the persona binds to a conversation when that conversation starts, so changing it mid-chat does nothing until you open a new one. The test takes ten seconds: change the name, start a fresh chat, see which name comes back.
A line in the setup box arrives with every reply. A line you typed in chat on day one may be gone by Thursday.
What to leave blank on day one
You are filling in this form before you have had a single conversation, so every opinion you hold about what you want is a guess. Leave the ambitious fields empty:
- Elaborate backstory. Add it later if you find you miss it. Most people do not.
- A shared history you have not had. Describing a relationship that is already six months old asks the character to bluff, and bluffing is what makes an app feel like it is humouring you.
- Scenario or mood fields you do not understand yet. An option whose effect you cannot predict is better left at its default, where the behaviour is at least the tested one.
Then put a note in your calendar for the end of the first week. By then you will know which habit grates, and one added sentence will fix more than anything you could have guessed on day one.
What to check before you pay
The setup screen is also an unusually honest preview of how an app will treat you as a customer, and you can read it on the free tier in five minutes. Five questions:
- Can you edit the character after creating it, or is it locked once made?
- Does an edit apply to the conversation you already have, or only to a new one?
- Is there a persona field at all, and can you see everything currently in it?
- Is there a memory list separate from setup, so you can tell your standing instructions apart from what the app has decided to remember?
- If a field is capped, does the paid tier describe its version as a number or as an adjective?
An app that lets you read and edit every instruction it acts on is one you can keep tuning for a year. An app that hides the fields and sells "deeper personality" as a feature is asking you to pay for something you can never check. That gap decides whether a subscription is worth it — and for a baseline to measure yours against, the app we currently recommend exposes both text boxes and its memory list on the free tier.
Frequently asked questions
How long should AI girlfriend app setup take?
About ten minutes, most of it in the free-text fields rather than the avatar. The look is cosmetic and changeable; the description and persona are the instructions the character acts on for every reply. Revise both at the end of your first week.
What should I write in the character description box?
Behaviour rather than biography: reply length, how often it asks questions, whether it pushes back, the tone you want. Four to six short instructions is a good target. Backstory only matters where it changes what the character says, and too much detail can make replies feel stilted.
Should I fill in the "about you" or persona field?
Yes, briefly — it is the most useful field on the screen, because facts about you stay in front of the model instead of scrolling away with the conversation. Keep it to what you would be comfortable storing on someone else's server.
