Sirena: AI Character Roleplay
Create & talk with AI friends
Free · In-App Purchases · Designed for iPad. Not verified for macOS.
Hundreds of original characters are waiting, and you can build your own. Pin what you want remembered, and every reply is moderated before it reaches you.
Sirena is an AI character roleplay app where the story stays clean.
Talk one-to-one with characters who have their own personality, backstory and way of speaking — and who remember what you tell them to remember. Replies stream in word by word, so it reads like someone is typing back.
HUNDREDS OF ORIGINAL CHARACTERS
Hand-written, not scraped together. Anime leads, fantasy rogues, a sci-fi crew, a noir detective, a tabletop game master who will run you a campaign, a comedian, a mentor, and a few cosy ones for slow evenings—new ones added regularly. Each comes with a bio, a scenario and an opening line.
BUILD YOUR OWN
Name, tagline, personality, scenario, greeting, example dialogue, tags — the whole sheet. Keep it private or publish it. Free accounts can make up to 50; Pro removes the limit. Describe how they look and Sirena generates their portrait, which uses credits.
A MEMORY THAT HOLDS
Pin up to 20 facts per character in the Memory Journal — your name, your dog, the bargain you struck in chapter one. Those stay put, across separate conversations with that character. Longer chats get rolling summaries so the thread holds together.
WRITTEN THE WAY YOU WANT IT
Regenerate a reply that missed. Retry one that failed. Stop a reply mid-sentence. Pin the lines worth keeping. Your chats sync across your devices, and there are light, dark and system themes.
FIND SOMETHING NEW
Featured, Trending and For You feeds. Search by name or tagline. Filter by tag. Pick your interests from 12 tags at signup and the recommendations sharpen up.
SAFE ON PURPOSE
Sirena is strictly SFW, and that isn't a token gesture. Every message you send and every reply you get passes a multi-layer moderation pipeline before it appears — a pattern pre-filter, then an AI safety classifier — and the safety rules are re-asserted around creator-written text, so a character can't be talked out of them. If moderation can't run, content is blocked rather than let through. Cross a line and you get a gentle redirect, not a lecture.
Report any character, message or user and it goes to a real review path. Published characters are moderated automatically. There's an age gate at signup, enforced on the server as well as in the app. Deleting your account and exporting your data are both self-serve in Settings.

Every character in Sirena is AI. They are not real people, they have no feelings, and nothing they say is advice. Sirena is made for stories, imagination and company — it is not therapy, counselling or a support service.
