LLM Playground

LLM Playground is an AI chat client that runs on the models you choose.

Connect an account or an API key from the providers you already use, and every model they offer shows up in one picker. No subscription on top of a subscription, no single vendor deciding which model you are allowed to talk to. There are also free models built in, so you can start a conversation the moment you sign in.

CHAT THAT KEEPS UP
- Streaming replies, Markdown and syntax-highlighted code blocks
- Automatic smart routing, or pin a specific model per chat
- Web search, file and image attachments, and voice input
- Follow-up suggestions so a conversation keeps moving
- Search across every message you have ever sent

AI CHARACTERS
Browse a library of community characters, filter by category, or build your own with a portrait, a personality and a greeting. Share it with a link or keep it private.

ROOMS
Group chats where several people and several AI characters talk in the same place.

PRIVATE BY DEFAULT
Chats can be end-to-end encrypted with a key that never leaves your device. The app stores the ciphertext, and only your device can read it back. Your prompts go to the provider you connected and nowhere else.

BUILT FOR ANDROID
- Read your chats with no connection at all
- Home-screen widgets for recent chats, a quick question, and unread replies
- Opens instantly from a locally cached shell
- Adapts to phones, tablets and Android XR, in portrait and landscape
- Four permissions in total: internet, network state, vibration, and the microphone for voice input

No ads. No tracking. No upsell.
