Bring Your Own AI vs Kapsula App

Bring Your Own AI is a private, bring-your-own-key chat client for the world's most capable AI models. Connect OpenAI, Anthropic, DeepSeek, Groq, OpenRouter, Ollama, or any OpenAI-compatible endpoint — plus Apple's on-device Foundation Model — and chat with all of them from a single, beautifully native iOS interface. WHY BRING YOUR OWN AI • BYOK (Bring Your Own Key). Your API keys live in the iOS Keychain, encrypted with Secure Enclave-backed AES-256. They never touch our servers. There are no servers. • Every model, one app. Switch between GPT-4o, Claude 3.5 Sonnet, DeepSeek-V3, Llama 3, Qwen, your local Ollama instance, and Apple Intelligence without juggling browser tabs. • Thinking, visible. Reasoning models (DeepSeek-R1, o1, etc.) expose their chain-of-thought — collapse or expand on demand. • Streaming. Watch responses render token by token, with full Markdown, LaTeX, and syntax-highlighted code blocks. • Auto-title. Conversations name themselves from the first exchange — never wade through "New Chat #47" again. WHAT YOU CAN DO • Multi-provider endpoint manager — test connectivity, edit base URLs, rotate keys, all in one place. • Per-conversation model selection — use DeepSeek for code, Claude for writing, GPT-4o for vision, all in the same session. • Code blocks with syntax highlighting (Swift, Python, JS, Go, Rust, 100+ languages). • Markdown rendering for headings, lists, tables, links, and inline math. • Image attachments to vision-capable models (GPT-4o, Claude 3.5 Sonnet, etc.). • Export any conversation as Markdown or JSON. • Siri shortcuts: "Hey Siri, new Bring Your Own AI conversation." • Local-first. Every conversation lives only on your device. AirDrop to back up. PRIVACY Bring Your Own AI does not collect any data. We have no analytics SDK, no telemetry, no remote logging. All conversations are stored locally in an encrypted SQLite database. All API calls go directly from your device to your chosen provider — we never see your prompts or responses. The app is open-source. REQUIREMENTS • iOS 26.0 or later • iPhone only • Apple Intelligence features require iPhone 15 Pro or later (A17 Pro / A18+) • A valid API key from at least one supported provider Bring Your Own AI is built by people who believe AI should be a tool, not a walled garden.

Run your own HTML tools on iPhone and iPad. Kapsula runs a self-contained HTML file inside the app. Start with code from an AI chat or a file you made yourself, then use it as a personal timer, checklist or other small tool. No separate app build or developer account is needed for your project. HOW IT WORKS 1. Get one HTML file with its CSS and JavaScript included. 2. Import the file or paste its code into Kapsula. 3. Open your project and use it on your phone. NATIVE FEATURES FOR YOUR CODE Compatible projects can use the kapsula JavaScript bridge for scheduled local notifications, persistent project storage, sound and haptics. These features require code that calls the bridge; importing a browser timer does not automatically add background notifications. A FOCUS TIMER TO TRY The guide at kapsula.app/chatgpt-html-to-phone-app/ includes a reference HTML file and a prompt for adapting it with an AI assistant. Test a 30-second notification, reopen the timer and change the work and break intervals. LOCAL BY DESIGN No Kapsula account or cloud service is required. Self-contained file and pasted-code projects work offline. The app does not collect analytics or track you. WHAT TO EXPECT Kapsula runs your tools inside Kapsula; it does not export standalone apps or run a backend. Projects with external services, packages or frameworks need a separate compatibility check. Notification delivery and sound depend on system permissions and device settings. Your HTML JavaScript is not a background service. KAPSULA PRO The app and its built-in demo are free. Your own projects need Kapsula Pro: a monthly subscription with a 7-day free trial for new subscribers, or a one-time lifetime purchase. Prices are shown in the app before you buy. The subscription renews automatically until you cancel; cancel any time in your app store settings. If Pro ends, nothing is deleted: your projects and their data stay on the device, locked until Pro is active again. Guide and examples: kapsula.app Bridge reference: kapsula.app/docs/ Privacy Policy: https://kapsula.app/privacy Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Import standalone TypeScript (.ts) files or paste TypeScript code, with on-device conversion and editable source. Your projects now come first on the home screen, with a clear Add project action and a separate demo. Fresh launches open the project list. Improved purchases, Pro restoration and file selection. TypeScript support is for one self-contained script without imports, exports, npm packages, JSX/React, namespaces or decorators. Conversion removes TypeScript syntax; it is not full type checking. HTML and plain JavaScript remain supported. Existing project storage and native APIs are unchanged.
