Lingki: AI Roleplay Sandbox

Lingki is a sandbox for AI role-play. Create characters, import character cards, and chat or write stories with them — powered by the AI model you choose.

BRING YOUR OWN AI
Connect OpenAI, Google Gemini, DeepSeek, OpenRouter, Mistral, xAI Grok, Groq, Ollama or any OpenAI-compatible endpoint with your own API key. Your messages go straight from your phone to the provider you pick. Lingki has no servers and no accounts.

CHARACTERS YOUR WAY
• Import character cards (PNG or JSON, V1/V2/V3)
• Create a character from a short idea with the AI character designer
• Give each character a persona, greeting, avatar and chat background

TWO WAYS TO PLAY
• Chat mode — text your characters like a messenger, with stickers, voice messages and images
• Story mode — write an interactive story together, and branch a reply into alternate versions

MORE THAN ONE-ON-ONE
• Group chats with several characters at once
• Characters can message you first, with notifications
• Voice calls with speech recognition and text-to-speech
• A drawing and guessing mini-game

MEMORY AND WORLDS
• Characters remember important details across long chats
• World books keep your setting, places and lore consistent
• Search your history and jump to any message

MAKE IT YOURS
• Four built-in themes plus your own custom themes
• Custom chat bubbles and backgrounds
• English, 简体中文, 日本語, 한국어 and Español

PRIVATE BY DESIGN
Everything — characters, chats, memories and your API key — is stored on your device. Back up and restore whenever you like.

Good to know
• An API key from an AI provider is required, and that provider's pricing and terms apply.
• Replies are generated by third-party AI models and may be inaccurate. You can report any AI message from inside the app.
• Lingki is intended for users aged 18 and over.
