Selidar — role-playing games powered by AI
We create living worlds where AI plays the characters, the narrator and the world around you — and the world remembers you: your choices, relationships and shared story.
What is Selidar
Selidar is an online platform for text-based role-playing games with AI. You choose a world, step into it as yourself and simply write what you do and say. Characters reply, the narrator describes what happens, and each scene is illustrated with the very place you are in.
Unlike an ordinary AI roleplay chat, every world runs on its own game engine. It keeps track of time, place, items, relationships and the consequences of your choices, so the story does not fall apart after a couple of evenings.
- Living characterswith personality and memory
- Whole worldswith their own history
- Your own journeythat keeps growing
Why we built Selidar
Neural networks have learned to hold a conversation, but a conversation is not yet a story. In an ordinary AI chat the character forgets your agreement an hour later, there is no world around you, and any decision can be undone with one phrase. We wanted something else: a world you can come back to a week later — and find it still alive.
That is why Selidar is built as a game. The neural network handles living speech, personality and imagination, while the game engine handles everything that must be reliable: time of day, place, money and resources, trust, promises and consequences. The AI cannot “forget” an important event or hand out what was not earned in play.
We make worlds for adults who love stories: some look for adventure and travel, some for warm relationships, some for language practice or a debate with a philosopher. We want every evening in Selidar to feel like a new chapter of a book you write together with the world.

Learn moreVirtual travel
Varun is a holiday by a warm sea on a planet with two suns: a guide, markets, sunsets and adventures that never follow a script. Your companion remembers past trips and what they learned about you, so you can come back again.
Learn morePhilosophical talks with AI
In the Hall of Minds, Socrates, Plato and Marcus Aurelius answer in their own manner, draw on authentic texts and argue for real. A good way to understand an idea, prepare for an exam or just think out loud.
Learn moreEnglish through roleplay
Language practice with an AI tutor in living scenes: order coffee, pass an interview, chat with a new friend. The tutor corrects gently and remembers what you are working on.
Learn moreCreate your own role-playing game
In the world constructor you can describe locations, heroes and plot on your own or with an AI co-author — no coding. A finished world can be shared with other players.

Under the hood: how living worlds work
The technology that keeps an AI role-playing game from falling apart after a couple of evenings.
A game engine, not a bare chat
Every turn goes through the world engine: it checks where you are, how much time has passed, what you carry and what is possible at all. The neural network describes the outcome but cannot override the rules.
Long character memory
Important events go into the world’s chronicle: meetings, promises, gifts, quarrels and reconciliations. The character relies on it even if the conversation was a month ago.
Illustrations you recognise
Scenes are drawn from the world’s description and the heroes’ looks, and each picture is checked against a reference so the character’s face and a familiar street look the same as yesterday.
Voice
Characters can voice their lines and you can answer by voice. Voice-overs are saved, so listening again is free.
Three ways to play with AI
Choose who “thinks” for the characters and draws the scenes. Switch any time — your worlds and progress stay.
Credit packs easiest
All generation happens on our side: powerful cloud models, images and voice. Nothing to set up.
Your own API key for enthusiasts
Connect OpenRouter, OpenAI, Anthropic, DeepSeek or any compatible server and pay the provider directly. The key is stored encrypted.
Locally on your computer free
Text, images and voice are generated on your Mac or Windows PC via the Selidar app. No AI fees.
