Pick a character and talk. Behind every reply she reads a running summary of what you have lived together, the recent conversation, your lorebook and anything you pinned, so the story you come back to is the one you left.
RAG + 1M CONTEXT + LOREBOOKS + FACE-LOCK
Meet characters from the live SultrAI catalogue, open their profiles and start a real private conversation before you pay.
Start with a house or community character. The first messages are free, so you can feel the chemistry before you commit.
A character with a good memory is not one that can recite message forty word for word. It is one that still knows your name, the promise she made last Tuesday, the rival you invented in the first scene and the way you like to be spoken to, without you repeating any of it.
Most chat apps only see the last stretch of the conversation. When the scene grows longer than that window, the oldest parts fall away and the character starts improvising over the gap. On SultrAI several layers of memory sit behind each reply, so the early chapters stay part of the story.
Every few messages the conversation is folded into a compact summary of the facts that last: who you are to each other, what happened, what was promised. That summary rides along with every reply, and it belongs to you and that one character.
The latest messages are sent as they were written, so tone, pacing and the last thing either of you said are never paraphrased away.
Write or import a lorebook of places, people and rules. When a scene mentions one of its entries, that entry is added to what the character reads, however long ago you wrote it.
With a free account, pin a message (a vow, a secret, a turning point) and it stays in front of the character for the rest of that story.

One conversation. A world that keeps unfolding.A slow romance and a one-night fantasy should not bleed into each other. On SultrAI you can keep more than one story going with the same character, and each one keeps its own history and its own record of what has happened in it.
Start a new story when you want a clean slate; go back to an old one and she picks it up where it stopped, with that story's events and nobody else's.
Personality, backstory, scenario and opening line: the character creator keeps every field, and the whole definition is sent with each reply.
Import a character card in PNG, JSON or CHARX format and its definition and lore come with it.
Link a lorebook to the character or to one conversation, and it is there for every scene that needs it.
Early in the chat, give her a name to remember, a place you met and something she promised.
Let the scene move on for a few dozen messages, long enough that the details are well behind you.
Close the tab, return later and ask about one of the three. That is the test that separates memory from a long scroll.
A returning reader, a day after the scene where the detail first came up:
There is no memory tier. Chat without an account or a card, with a free daily message allowance as a guest, and the conversation is saved and remembered from the first exchange. A free account has its own daily message allowance and adds pins. Credits only pay for photos.
Characters that keep the important parts of a long story instead of forgetting everything older than the last few messages. On SultrAI that comes from a running memory summary, saved chat history, lorebooks and pinned messages working together.
Yes. Your messages are saved and folded into a per-character memory summary, so a character still knows what happened between you when you come back days later.
Yes. Memory works from your first message, including as a guest with a free daily message allowance. A free account has its own daily allowance and adds pinned messages.
Yes. Write or import a lorebook and attach it to the character or to a conversation. Entries are brought into the scene when they come up, so a large world does not have to fit in every message.
Yes. Each story keeps its own history and its own record of what has happened in it, so a slow-burn romance and a one-off scenario never mix.
Yes. PNG, JSON and CHARX character cards import with their definition and lore, and the full definition is used on every reply.
Pick a character and talk. Behind every reply she reads a running summary of what you have lived together, the recent conversation, your lorebook and anything you pinned, so the story you come back to is the one you left.
