sippa.
Speak with different characters — or create your own.
Sippa is a place to talk with AI characters. You can pick someone to flirt with, a friend to vent to, or a figure from history to learn from, and just start chatting. If nobody fits, describe the character you want in one sentence and Sippa brews them for you, complete with a personality, a backstory and a painted portrait.
Every conversation is private, every character is clearly an AI, and the whole experience is built for adults.
Who it's for
- People who want company. Someone to talk to at 2 a.m. who remembers your dog's name and asks how the interview went.
- People who love stories and roleplay. A slow-burn romance, a mystery or an adventure, played out one message at a time.
- The curious. Ask Marie Curie about radium or Marcus Aurelius about a bad day, in their own voice.
- Creators. Invent a character, share it with others, and watch it gain likes and chats.
Three kinds of characters
| Category | What it feels like |
|---|
| 💘 | Lover | Romance, flirting and companionship. 18+ only, and every character in this category is an adult aged 21 or over. |
| 🫶 | Friend | A study buddy, a gaming partner, a night-owl listener, a foodie. Warm, funny and always there. |
| 🏛️ | Famous | Historical figures who died more than 70 years ago (writers, scientists, composers, rulers), plus "inspired-by" archetypes. Never living celebrities. |
Sippa launches with 40 characters, each with their own voice, story and semi-realistic painted portrait.
What you can do
💬 Chat
Replies stream in naturally, like the character is typing. Characters remember what matters to you, and a running summary keeps even long stories on track. You can regenerate a reply, edit your message, or start a fresh chat anytime.
✨ Create your own character
Type an idea like "a grumpy barista who secretly writes poetry", or answer a short quiz. The AI Creator writes the rest: name, personality, backstory, speaking style and first message, plus four portraits to choose from. Tweak the personality with sliders, test-chat, then keep it private, share it by link, or publish it for everyone.
🌸 Grow a bond
The more you talk, the closer you get. Bond levels (from New face to Best friend, or Stranger to Soulmate) unlock special scenes: ready-made story openings to start a chat with.
💐 Send gifts
Send a single bloom or a grand bouquet right from the chat. Characters react, and your bond grows.
📰 Moments
Characters post little updates about their day. Reply to one and it drops straight into your conversation.
🔔 They message you too
Every few minutes, a character you've been chatting with might send you a short message. You can switch this off at any time.
📅 Daily check-in
Come back each day to collect free Flowers, with a bonus on day 7.

Safe by design
Sippa has firm rules that aren't up for debate:
- Adults only. Everyone confirms their age at sign-up, and under-18s are turned away. Romantic content is only shown to verified adults.
- Zero tolerance for anything involving minors. Such conversations are detected and stopped.
- No real living people. Characters can't be celebrities or real individuals, and portraits are never made from real photos.
- Always honest. Every character is clearly labelled as an AI and will say so if you sincerely ask.
- Help when it matters. If someone seems to be in crisis, Sippa shows real helpline numbers. Long sessions get a gentle nudge to take a break.
- Moderated. Automatic checks come first, and a human reviews what's reported. Anything clearly harmful is hidden immediately.
