Cumbersome vs Sleek BYOK

Use Apple Private Cloud Compute, your API keys, or an 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 apps hide the controls I want and lock me into one provider. I wanted direct API access, the freedom to pick and compare models, and to pay providers for what I use. This is the app I use every day, so I pay attention and try to get it right. SUPPORTED PROVIDERS - Apple Private Cloud Compute - 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 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. Stream multiple chats in parallel and let an AI judge pick the best. - Bring your own tools. Local browser use, reasoning, web search, image generation. - Rich, editable conversations. Markdown, LaTeX, code blocks, attachments, edit and export anything. - Private by design. iCloud sync across devices. Nothing saved to our servers. - Native and accessible on iPhone, iPad, and Mac.

Sleek is a native iOS client for OpenRouter — bring your own key and get every major AI model in one clean, fast, beautifully minimal app. No Sleek account. No middleman servers. Your OpenRouter key stays on your device, and every request goes straight from your iPhone to the model. You pay OpenRouter's raw per-token rates for AI usage — no markup from us, ever. One app. Every modality. • Chat with hundreds of models — Claude, GPT, Gemini, Llama, and more — and switch between them in a tap. • Generate images with the latest image models, right in the conversation. • Generate video from a prompt and save it straight to Photos. • Talk hands-free with live push-to-talk voice — speak, get a spoken reply back. • Dictate into any chat with universal on-device audio capture. • Make music and download the track. Built to feel high-end. A dark, distraction-free interface with smooth streaming, clean markdown, and thoughtful micro-interactions throughout. It looks and feels like a flagship app — because it is one. Make it yours. • Presets — save reusable system prompts and parameters for different jobs. • Per-modality prompts — steer image style, voice delivery, music genre, and more independently. • Memories & folders — keep context organized and let the app pull in what's relevant. • Model explorer — browse full stats, pricing, and context windows for every model, and set defaults per task. • Fine control — temperature, max tokens, provider routing, and more when you want it; sensible defaults when you don't. Private by design. Sleek has no backend of its own. There's no analytics pipeline, no Sleek account, and no server that ever sees your conversations or your key. Everything lives on your device. What you need to get started: Sleek runs on your own OpenRouter API key (free to create at openrouter.ai). Two ways in: • Connect OpenRouter — sign in once and Sleek provisions a key automatically. No copy-pasting. • Paste a key — already have an OpenRouter API key? Add it in Settings, no account needed. Minimal on the outside. Every model on the inside. That's Sleek.
