Cumbersome: AI API Client

OpenAI & Anthropic API Client

Kostenlos

IMPORTANT: Requires your own API keys from OpenAI, Anthropic, or Google AI Studio. This is intentional. I'm Peter, an indie developer in Portland, Oregon. I built Cumbersome mostly for myself because I was frustrated with how consumer AI apps actually work. Cumbersome is the manual transmission of AI apps: more complex, but with far greater control. WHY I BUILT THIS It's claimed that ChatGPT, Claude, and Gemini route requests to cheaper models behind the scenes to manage costs. 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 iOS and macOS app that connects directly to OpenAI, Anthropic, and Google AI Studio APIs. I wanted to pick exactly which model I use and know I'm getting it. I wanted to compare Claude Opus 4.5, Gemini 3, and GPT-5 on the same prompt. I wanted to pay per use instead of subscriptions. So I built it. WHAT YOU GET — Face/Off Mode generates 3 responses at once and an AI judge picks the best one. Overkill for casual questions, but it makes a real difference when quality matters. — Full control over model parameters. Temperature, tokens, system prompts, reasoning effort. The same technical controls developers get in official API playgrounds, but on your phone. — Switch between ChatGPT models, Claude, and Gemini mid-conversation. Try a prompt on both and compare the responses. — Edit any message in your conversation history. Consumer apps lock your context once you send it. Cumbersome lets you remove tangents, fix mistakes, and reshape the conversation. — Native apps for iPhone, iPad, and Mac with iCloud sync. Your conversations stay on your devices and sync through your personal iCloud. I never see your data because it never touches my servers (I don't have any actually). WHO THIS IS FOR If you pay for ChatGPT Plus or Claude Pro and hit usage limits, this gives you unlimited access at lower cost. If you want to try different models without juggling multiple subscriptions, this puts them all in one app. If you care about exactly which model is responding to you, this guarantees you get what you pick. If you want AI to just work without thinking about API keys or model selection, consumer apps are probably a better fit. No hard feelings. THE DEAL The app is free. You pay OpenAI, Anthropic, and Google directly for API access. I'm out of the money flow entirely. One person. No VC money. No growth hacking. Just a tool I wanted to exist.

feat: auto-shrink images to 4mb to account for strict Anthropic image size limits. feat: long-click on any user message to restart convo from that point, allowing for renewing conversation history by restarting the chat at any prior user message in a convo. feat: long-press chat Send button provides context menu to send to new chat vs the existing one. fix: a bug prevented icloud sync of chats with images/pdfs/files across devices. this fixes. IMPORTANT: delete old convos that have images/files for sync to work again.
