The DIY AI girlfriend kit, explained one part at a time

Four parts, no forced order, every one of them refittable after she is assembled. This page is the instruction sheet: what each part actually changes, and which order tends to survive.

Fictional AI characters, written as adults. Nobody here is a real person.

02The detail

The four parts, and what each one really controls

Every part in the kit answers a different question, and only one of them is about how she sounds.

A DIY AI girlfriend is assembled from four rows on one sheet. Voice decides register and vocabulary — dry, warm, blunt, playful. Manner decides pace and initiative: how long her replies run, whether she starts conversations, how forward she is before you have asked. Those two are what people notice in the first five minutes.

The other two decide whether the build lasts. Memory is the part that carries names, plans and running jokes between visits, and it is the difference between a character and a chat window. Limits is where you write down what she never brings up and where she stops, which sounds like paperwork and is in fact the part that stops a build going somewhere you did not want it to go on a Tuesday night.

Order matters more than the kit lets on. Fitting limits first feels pedantic and is the single change that most reliably produces a build people keep — everything after it is decoration on a foundation, rather than a correction applied late.

What works well

  • Four named decisions instead of one empty description box
  • Any part can be pulled and refitted without disturbing the rest
  • The preview answers differently after every part
  • Nothing is locked behind an earlier step
  • A minimal two-part build already holds a conversation
  • The sheet shows what is pending instead of blocking you

Worth knowing first

  • Four parts cannot express everything a long written brief could
  • The order you fit them in genuinely affects the result
  • Memory and the deeper limits sheet are paid parts
  • Fictional AI characters only, and strictly 18+

03On this page

Three sheets, same four parts, different order

Nothing separates these builds except which row was filled first and how hard each one was pushed.

Fictional AI character whose voice part was fitted first, standing indoors

Voice first, limits last — the fastest build to make and the one most often redone.

Fictional AI character built for slow conversation, sitting on a sofa

Manner fitted for long, slow replies, which changes her more than the voice part did.

Fictional AI character refitted twice before the build was kept

Limits written before anything else. Two months later this sheet is still unchanged.

04In practice

Refitting a part without starting over

Pulling a part is not a reset. Swap the voice row and her manner, memory and limits stay exactly where they were — the next message arrives in the new register with the same history behind it. That is the practical reason the kit is four separate rows instead of one description field: a description has to be rewritten wholesale, a row does not.

In practice most people refit twice in the first week and then stop. The usual pair is slowing the manner part down and tightening one line in limits, after which the sheet tends to sit untouched and the thread just continues.

05Quick answers

The kit — quick answers

01

What are the four parts of a DIY AI girlfriend here?

Voice, manner, memory and limits. Voice sets register and vocabulary, manner sets pace and initiative, memory decides what carries between visits, and limits records where she stops. Each is a row on one sheet and each can be refitted later.
02

Is there a right order to fit them in?

There is no enforced order, but limits first produces builds people keep. Voice first is more fun for ten minutes and is the order most often redone, because a limit added after a conversation has drifted feels like a correction rather than a design.
03

Can I build more than one?

Yes. Sheets are separate, so a slow, boundaried build and a fast, teasing one can exist side by side without either overwriting the other. Parts can also be lifted from one sheet onto another.
04

How long does the first build take?

About ninety seconds if you know what you want, and rather longer if you keep previewing. Two parts are enough to open a thread, so nobody has to sit through all four rows before the first reply.
05

Does refitting a part wipe the conversation?

No. The thread and its history stay. A refit applies from the next message onward, which is why swapping the voice mid-conversation is a normal thing to do here rather than a destructive one.

07Start the build

Open a blank sheet and fit the first row

Confirm you are 18, pick a part, and read the preview before you fit the second. The whole kit is four rows and the first reply does not wait for the last one.
