A private space for fantasy and roleplay.

Nymbrail is a private AI companion for adults who want to explore fantasy and roleplay at their own pace — with selectable fictional characters, an on-screen presence, a respectful tone, clear consent boundaries, and controls you set.

The experience

Your imagination, with more dials to turn.

Nymbrail makes the companion feel less like a fixed character and more like a presence you can keep refining.

Choose the personality

Set the personality and interests that should guide the companion’s tone and curiosity.

Set the scenario

Describe the setting, premise, or roleplay context you want the text conversation to follow.

Write the boundaries

Your consent boundaries are active instructions the companion is expected to honor in every response.

Set privacy preferences

Describe the privacy preferences the companion should keep in context inside your private workspace.

The edges matter

Consent is part of the experience.

You decide what the companion should honor. Saved boundaries are included in its context and guide each response; if a request conflicts with a boundary, it should acknowledge that and redirect within the boundary.

18+ assurance is required before chat opens
Saved consent boundaries guide the text companion each time you return
Your setup and one conversation are stored in a private workspace tied to your account

Privacy here means a private workspace tied to your account. It is a clear product behavior, not a promise of absolute secrecy.
