Sleek BYOK vs OpenChat Connect

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.

OpenChat Connect is a free native iOS app with two ways to chat. Download a model and talk to it on your iPhone. Or bring your own API key and use OpenAI, Claude, Gemini, OpenRouter, or any custom endpoint. No OpenChat account. No lock-in. On this device Version 1.2.0 adds curated MLX downloads from Meta, Qwen, and Phi. Pick Fast, Balanced, or Strongest, then choose the On This Device provider. That chat runs on the iPhone. You do not need an API key for it. Your key, any model Paste a key and use OpenAI, Claude, Gemini, OpenRouter, or a custom OpenAI-compatible endpoint, including Ollama, LM Studio, or vLLM. The same key setup also covers Mistral, DeepSeek, cloud Qwen, Moonshot, Z.ai, and 01.AI. Pick the model that fits the task. Switch later. The app does not lock you to one provider. One app either way Chats, rules, memory, and skills are stored on the device. You can set global rules and per-chat rules, edit memory, and run a skill with / in the composer. Web search is optional and uses your own search key (Tavily, Exa, Brave, Serper, or SerpAPI). The app can render streaming Markdown and code, send a photo to a vision-capable model, and finish a cloud reply in the background with a local notification. Private by design OpenChat has no backend, no account, and no analytics. On-device model chats are not sent to a cloud model provider. When you choose a cloud model, that message goes from your iPhone straight to the provider you picked. OpenChat does not sit in the middle. API keys and search keys stay in the iOS Keychain. The app is free. Cloud usage is billed by the provider on your key, not by OpenChat. On-device chats do not use a provider key.
