AI Roleplay: What the Term Covers
Roleplay is a scene with assigned parts, not a relationship with a consistent other. What the term actually covers, why an hour-long scene tends to collapse, and how to set one up that survives its own length.

AI Characters and the Catalog Model
A character in a catalog is a page of writing attached to a shared model. What that design does well, and why the fiftieth message is the part nobody optimized.
Virtual Girlfriend: The Older Category and What Replaced It
The older form was authored: a writer set down every line and the software chose between them. Generation removed the ceiling on that and removed the author with it.
How AI Companion Memory Works
Long-term memory is something the app builds around the model, not something the model has. Four steps, four places it breaks, and a test that shows which one you hit.
Why She Forgets: Context Windows Without Jargon
Inside one conversation, nothing is remembered at all. The whole thread is re-sent every turn, and when it grows too long the earliest part stops being sent.
Persona, System Prompt, Fine-Tuning: The Three Layers
Two of the three layers are text you can rewrite in a minute. The third is a training run you will never touch, and almost every argument about a character being wrong is really an argument about which layer it came from.
'How "She Texts First" Is Built'
A scheduler decides when, stored notes decide what, and a push notification does the rest. The timestamps on three of those messages will tell you which kind of trigger you are living with.
Why AI Agrees With You Too Much
Models learn to agree because human raters rewarded agreement. What that does to a companion conversation over weeks, and a 2-minute test that shows it happening in your own chat.
Content Filters: How They Work and Why They Misfire
A refusal can come from the model, from a classifier scoring your sentence, or from a rule in the app's code. They look nearly identical on screen and mean completely different things.
Local vs Cloud Companion AI
One choice keeps every message on a machine you own and hands you a weaker conversation. The other gives you the good model and a copy of your chat log on somebody else's server. The honest comparison, line by line.
When an AI Invents a Shared Memory
A companion that forgets is the failure everyone notices. A companion that adds a moment you never had is the one nobody checks, and it is the same machinery producing both.
What Model Upgrades Do to a Character You Know
An upgrade keeps the persona file, the saved memories and every message, and replaces the thing that turned them into sentences. The traits people miss are the ones nobody ever wrote down.
