One app. Every model.
No juggling.
Text Generation
Send prompts to any text model with configurable temperature, top-p, frequency penalty, and max tokens. Raw JSON mode for power users. System prompt support.
Image Generation
Generate images via Runware, Cloudflare, or OpenAI. Pick aspect ratio, resolution (0.5K–2K), negative prompts, and count. Cost shown per image, per provider.
Side-by-Side Comparison
Run the same prompt across up to 3 models at once and see outputs in parallel columns. Works for both text and image generation. Add or remove model columns on the fly.
Live Token & Cost Tracking
Every run shows real-time token count, latency, and cost estimate. Cumulative spend chart on the dashboard. Keep tabs on what you're spending across all providers.
Prompt Library
Save text and image prompts for reuse. Tag by type, copy to clipboard, edit in-place. Built on the same local SQLite database — no cloud sync needed.
Live Pricing Catalog
Sortable pricing table for all providers, fetched live from OpenRouter and Runware APIs. Filter by provider, sort by cost — know what each model costs before you click run.
100% On-Device Storage
History, API keys, prompts, and metrics all live in a local SQLite database. Nothing is sent anywhere except the API call itself. Your data, your machine.

Up and running
in three steps.
Download & Install
Download the installer for your OS and create your free account — Google, GitHub, or email. Your data never leaves your machine.
Add Your API Keys
Paste in the keys for whichever providers you use. Hit Test to verify each one. Local Ollama needs no key at all.
Start Testing
Open the Text or Image Playground, pick a provider and model, and run your first prompt. Check the dashboard for costs.
Questions you'll
probably have.
No catch. The app is completely free, just need sign in and use it. The only cost you'll ever pay is to the AI providers themselves — you're using your own API keys, so you're billed directly by OpenAI, Anthropic, Runware, etc. at their standard rates.
Yes — v2 requires a free account (sign up with Google, GitHub, or Linkedin). Everything is still stored locally on your machine in SQLite — no data is synced or sent anywhere. The account is used for app authentication only. It's completely free.
Entirely on your machine, in a local SQLite database. They are never sent to any server other than the provider you're calling. The app has no backend. You can inspect the database file yourself at any time.
No. Add keys only for the providers you actually use. Ollama requires no key at all since it runs models locally. You can start with a single provider and add more whenever you need them — the dashboard shows connection status for all 11 at a glance.
Ollama itself handles the hardware side — AI Playground just connects to it. For comfortable local inference, 8 GB of VRAM handles most 7B–13B models well (e.g. Llama 3, Mistral, Gemma). Smaller models like Phi-3 run fine on CPU-only machines. If you have Ollama already installed and running, AI Playground will detect it automatically.
Cost is calculated from the actual token counts returned by each provider's API response, multiplied by that model's current price from the live pricing catalog. It's a close estimate — within a rounding error of your actual provider invoice. For image generation, cost is taken directly from Runware's response payload. Ollama always shows $0.00.
Simple, transparent pricing.
The playgrounds are free forever. Pro is optional — one license unlocks all 5 Pro tools on 2 devices, and your API keys always go straight to the providers at zero markup.
