# LLM Playground

> LLM Playground (llmplayground.net) is a free AI workspace: every major AI model, user-created AI characters, image generation, web search, deep research and group rooms — in one fast app. Sign up with just a username (no email, no credit card) and start immediately: every account includes a built-in model with unlimited messages, free. Bring your own API keys to add GPT, Claude and any OpenAI-compatible provider at your provider's own prices — LLM Playground is a client, not a reseller, and never marks up your usage.

## Why people pick LLM Playground
- Actually free: every account includes a built-in model with unlimited messages — no trial, no paywall, no email address, no credit card.
- Every model, one place: sign in with Airforce, Pollinations or g4f — plus NavyAI, VoidAI, routing.run or any OpenAI-compatible API key — and switch models whenever you like.
- You stay in control: bring-your-own-key means your provider bills you at its own prices; credentials are encrypted; nothing is resold.
- A full character platform: create, publish and chat with AI characters (Character Card v2 import/export), with personas, worldbooks, scenes, collections and group roleplay rooms.
- Far more than chat: image generation, web search, deep research, document analysis AND creation (the AI writes PDFs, Word documents, spreadsheets and images for you, sandboxed, with download links), long-term memory, a model comparison arena, cost comparison and token counting, automations and scheduled prompts, and fully custom themes.

## Who it's for
- Anyone who wants free AI chat without buying yet another subscription.
- Roleplayers who want real model choice — a serious Character.AI / JanitorAI alternative.
- Developers and tinkerers comparing models across providers in one interface.
- Anyone with existing API credits who wants a polished client for them.
