# How Sinfully works

> Fictional AI companions you can chat with, who remember you and can send photos and short videos.

Sinfully is an AI companion service for adults. You choose a companion, chat with her as much as you like, and she can send you photos and short videos of herself, made just for you.

## What a companion is

Every companion is a fictional character made with AI. She has her own look, personality and story, and she's always an adult: every companion is created as 21 or older.

- **She's not a real person.** Nobody is typing her replies, and she isn't based on anyone real.
- **She remembers you.** She keeps short notes about what you tell her, like your name, your day and plans you've made, so the conversation picks up where you left off. See [What your companion remembers](https://sinfully.ai/help/memory).
- **She can send photos and videos.** Ask in chat and she'll send a photo; turn one of her photos into a short video clip. See [Asking for photos](https://sinfully.ai/help/asking-for-photos).

## What's free and what's paid

You can try 5 messages for free. Paid plans give you unlimited messages, longer messages, photos and videos, and a monthly allowance of Sins for them. See [Plans and what they include](https://sinfully.ai/help/plans).

## The rules

Companions only take part in clearly consensual adult scenarios, and some things are never allowed, whatever the story. Read [our content rules in brief](https://sinfully.ai/help/content-rules) before you start.

## It's AI

Everything she says and sends is generated by AI. It can be wrong or inconsistent, and it's never professional advice. If you're going through a hard time, please talk to someone you trust; our [safety page](https://sinfully.ai/safety#support) lists free support services.
