IMPORTANT: Requires your own API keys from OpenAI, Anthropic, OpenRouter, Google AI Studio, Z.ai, or Vercel AI Gateway, or your own OpenAI-compatible endpoint. I built Cumbersome because consumer AI apps kept dumbing things down. Cumbersome is the manual transmission of AI apps: more complex, but with far greater control. WHY I BUILT THIS Consumer AI providers like ChatGPT and Claude route requests to cheaper models to keep their costs down. They charge monthly subscriptions whether you use them once or a thousand times. They hide the technical controls that let you tune how models respond. And they lock you into one provider. I wanted an AI client that connects directly to AI provider APIs. I wanted to pick exactly which model I use and know I'm getting it. I wanted to compare different models on the same prompt. I wanted to pay per use instead of subscriptions. So I built it. This is the app I use every day to interact with AI, so I pay attention and try to get it right. SUPPORTED PROVIDERS Bring your API keys, or add your own OpenAI-compatible endpoint, for any of the following: — ChatGPT / OpenAI — Claude / Anthropic — Gemini / Google AI Studio — OpenRouter multi-provider — Vercel AI Gateway multi-provider — Z.ai — OpenAI-compatible custom endpoints, including Ollama, Azure, LM Studio, Groq, Together, and self-hosted backends WHAT YOU GET — A free app. — A versatile API client. One app, every major provider and model. — Total control. Pick your model, tune the parameters, switch providers mid-conversation. — Compare models head to head.
