How to Judge a Free AI Girlfriend App
Everything in this category is free until it isn't. The useful question is not whether there is a free tier but where its edge sits.
The journal
Blog
Explanations of the machinery underneath AI companion products — what a context window is and why your chat forgets, how memory is actually built, where free tiers put their ceiling, and what these apps keep. Written for people who use them, not for people building them.

Every piece here explains one mechanism and stops. None of them is a review.

AI Girlfriend Memory, Explained Without the Marketing
Every companion app advertises memory. Almost none of them mean the same thing by it. Here is what the word is actually covering.

What a Context Window Is, and Why Your Chat Forgets
The number in the spec sheet that nobody explains. Here is what it measures, and what happens the moment your conversation outgrows it.

A Practical Privacy Guide for AI Companion Apps
Companion chat is the most personal category of consumer AI there is. Five checks before you type anything you would not want read back.
What is coming
The journal is being filled in order of usefulness rather than all at once.
Service pieces first
Things that go wrong in specific products — an app that will not load, an API key that will not attach, a filter that changed overnight. These are the cheapest questions to answer well and the ones people are actually typing into a search box at the time.
Then the longer explanations
Regulation, research on companionship and loneliness, and the practical craft of writing a character that holds up over a long conversation. Slower to write, and they age better, so they come once the service pieces are in place.
Unpublished pieces are not linked from anywhere on this site until they exist. A link that leads to a missing page is worse than a gap in a list.
How these are written
Three habits that shape every piece here, and that explain the ones we do not publish.
One mechanism at a time
A piece explains a single thing — how memory is stored, where a window runs out, why a free tier stops where it does — and then stops. Round-ups of ten products with a paragraph each are easy to write and teach nobody anything, so we do not write them.
Explanations, not verdicts
Nothing here awards a score, and nothing declares a winner. Once you understand why something behaves the way it does, you can judge whether it suits you far better than a stranger who has never seen the conversations you want to have.
Written to age slowly
We avoid figures that change monthly — prices, tier limits, model names — and describe the shape of a constraint instead. A piece that is still accurate in a year is worth more than one that was precise for six weeks and quietly wrong afterwards.
