DeepCode is a minimal, developer-first AI chat app built for one purpose: helping you write better code, faster. How it works 1. Enter your OpenAI-compatible API key and base URL. 2. Pick your model — GPT-4o, GPT-4o Mini, or any custom model. 3. Start a chat. Ask anything: explain a function, debug an error, refactor a block, or brainstorm an architecture. Built for developers 1. Code-first formatting — AI responses render with syntax-highlighted code blocks you can copy in one tap. 2. Session management — Keep multiple conversations organized. Jump between projects without losing context. 3. Bring your own API — Connect to OpenAI, Azure, Anthropic, Gemini, or any custom endpoint. You control the provider, the model, and the cost. 4. No subscriptions, no tracking — We don't collect your code, your conversations, or your API keys. Everything stays on your device. 5. Dark mode by default — Easy on the eyes during late-night debugging sessions. Perfect for 1. Quick code explanations on the go 2. Debugging when you're away from your IDE 3. Learning new languages and frameworks 4. Brainstorming architecture and design patterns 5. Reviewing pull requests from your phone Supported providers OpenAI Azure OpenAI Google Gemini Anthropic Claude Any OpenAI-compatible API endpoint DeepCode is designed to stay out of your way. No onboarding tutorials, no feature bloat, no upsells. Just a clean chat interface that gets you answers you can actually use.

OnDevice is a local-first AI studio for iPhone. Run compatible language, vision, speech, and image models on your device. Browse models and choose what to download. Model size, memory use, and speed depend on your hardware. CHAT AND CREATE Ask questions, write, work with code, save snippets, and export conversations. Use camera or photo input with a compatible vision model, or use built-in OCR without downloading a vision model. Voice conversations use local Apple speech by default, with optional downloadable neural voices. Compatible image models support local image generation, which can be restricted with a parental PIN. YOU CHOOSE THE CONNECTIONS Local inference uses installed models. Network features are optional: model discovery and downloads, web search, paired Mac tools, a local API, and iCloud sync. Web providers may receive the queries or content you choose to send and may require their own API account. No app account is required for local use; there is no analytics SDK. REQUIREMENTS Requires iOS 18 or later. Downloadable models need storage and sufficient available memory. The app may pause or refuse heavy workloads when the device is too hot or memory is low. Model compatibility and performance vary by device.
