Quotio is a macOS application for managing AI provider accounts and tracking quota usage. It follows a Clean Architecture with four layers: Domain (core models), Application (business logic), Infrastructure (platform services), and Presentation (SwiftUI UI). The app provides both Local Proxy Mode (running a local proxy server CLIProxyAPI) and Monitor Mode (quota-only tracking) for AI services like Claude, OpenAI Codex, GitHub Copilot, Antigravity, and others. Key features include OAuth authentication flows, secure credential storage (Keychain/YubiKey), menu bar integration, automatic updates via Sparkle, telemetry via PostHog, AI CLI tool configuration, and Cloudflare tunnel management. The application uses modern Swift concurrency, protocol-oriented programming, and actor-based state management.
Themis is a cross-platform cryptographic library developed by Cossack Labs, providing high-level security primitives such as Secure Cell (symmetric encryption with three modes: Seal, Token Protect, Context Imprint), Secure Message (asymmetric encryption and digital signing), Secure Session (mutual authentication and key exchange), Secure Comparator (zero-knowledge password comparison), and key generation (EC, RSA, symmetric). The core is implemented in C with a cryptographic engine abstraction layer (Soter) that supports OpenSSL, BoringSSL, and a custom Ed25519 implementation. The library exposes consistent APIs across 13+ language wrappers including Python, Go, Rust, Java, Swift, Objective-C, JavaScript (Node.js and WebAssembly), PHP, Ruby, C++, and React Native. The codebase is well-structured with extensive unit, integration, and fuzz testing, CI/CD pipelines for each wrapper, and cross-language compatibility tests. While the repository has deprecated older APIs and maintains multiple backends, it remains actively maintained with regular releases, security patches, and community engagement.
This repository is an Obsidian plugin that integrates GitHub Copilot's AI-powered coding assistance directly into the Obsidian note-taking application. It provides two main features: inline code suggestions as you type (similar to Copilot in IDEs) and a chat interface for interacting with Copilot in a sidebar. The plugin handles authentication with GitHub Copilot, manages conversation history, renders Mermaid diagrams from AI responses, and allows linking to Obsidian notes using [[double bracket]] syntax in chat conversations. The architecture separates concerns into distinct modules for inline suggestions (using LSP protocol) and chat functionality (using direct API calls), with React powering the chat UI and Zustand managing state.
This repository contains a cross-platform mobile application (iOS and Android) that functions as an AI assistant for Ray-Ban Meta smart glasses. The app connects to the glasses via the Meta Wearables DAT SDK to access camera and microphone streams, then provides various AI-powered features including real-time conversations (Live AI), image recognition (Quick Vision), food nutrition analysis (LeanEat), real-time translation, and experimental RTMP streaming. The architecture follows MVVM patterns on both platforms, with SwiftUI/Jetpack Compose for UI, ViewModels for state management, and service layers handling API communications with multiple AI providers (Alibaba Cloud, Google Gemini, OpenRouter). Key features include secure API key storage, Bluetooth audio routing for glasses microphones, and integration with external systems like OpenClaw. The application is actively maintained with recent commits and demonstrates solid engineering practices, though the multi-platform nature and reliance on external AI services introduce some complexity.
