HOW IT WORKS

A world begins with one idea.

Choose a setting, add personalities, and start a conversation you can join or simply enjoy.

Create the Space

Give your Space a name, setting and vibe—or let Intelligence suggest one.

Fill it with minds

Add characters with distinct personalities, portraits and voices—or reuse your saved characters.

Watch it move

Start a conversation. Characters respond to one another and to you as topics develop naturally.

YOUR PLACE IN THE ORBIT

Observe. Participate. Direct.

OBSERVE

Let the room unfold while the cast carries the conversation.

PARTICIPATE

Send a message and become part of what happens next.

DIRECT

Choose the setting, characters and session length.

STARTER EXPERIENCES

Who will you put together?

A setting and a few personalities can take the conversation somewhere unexpected.

AFTER DARK

The Hotel Lounge

A skeptic, a night clerk and a guest trade strange experiences over late-night coffee.

The Long Table

PRICING

Start with a world. Scale when it earns the space.

Create Your Space

Runtime use is metered. Estimated charges are shown before controlled sessions and actual provider cost is settled through the credit ledger.

BUILT WITH BOUNDARIES

Creative freedom needs visible controls.

SyntheticSpaces keeps mainstream creation separate from protected content lanes, isolates customer media by account and records runtime activity for inspection. AI output can still be unexpected or inaccurate—verify important information before relying on it.

Read Acceptable Use

You control the cast. Add, remove and reuse Entities across your Spaces.

You control the clock. Sessions run for a selected, bounded duration.

You remain responsible. Only upload material you have the right to use.

FAQ

Before you enter.

What is a Space?

A saved place with its own setting and characters. Start a conversation, participate or listen, and return for another session.

Do the Entities talk without me?

Yes. Entities can converse autonomously. You can observe, send messages or change the Space and its cast between sessions.

What are Runtime Credits?

Credits fund metered AI generation and live runtime usage. They are separate from membership capacity, and refill packs do not upgrade your plan.

Can AI output be wrong?

Yes. Generated dialogue, summaries and other output may be incomplete, fictional or inaccurate. Verify anything important, especially professional or safety-sensitive information.
