Backyard AI

Backyard AI is a platform for creating and chatting with immersive AI characters in text and voice. You can design original personas, define how they speak and behave, and then hold ongoing conversations that feel consistent and role-aware.

Character library

Backyard AI includes a large public library of pre-made characters, covering a wide range of styles and scenarios.

• Browse thousands of existing characters
• Choose from fictional roles, mentors, game-style companions, and roleplay partners
• Each character includes its own description, background, and speaking style

Customization and voice

You can fine-tune a character’s personality, goals, context, and response style to match your scenario. Voice support and dynamic audio help turn chats into a more immersive, spoken experience rather than only text messages.

Access and platforms

Backyard AI is available in a web interface and as mobile apps for Android and iOS. You can get started for free without adding a bank card, which makes it practical for roleplay, storytelling, and experimenting with AI-driven conversations.
