yottoCode is a native macOS application that connects Claude Code with Telegram, allowing users to control AI coding agents directly through the Telegram messaging platform. Built on Anthropic's official Agent SDK, it provides full desktop capabilities accessible from any device running Telegram.

Key features include interactive permissions via inline keyboards, session resume with full history, model switching between Haiku/Sonnet/Opus, MCP server integration, live cost tracking, voice input/output with local Whisper transcription, real-time streaming responses, file sharing capabilities, and screenshot functionality. The app supports both voice notes transcribed by Whisper and text-to-speech responses that run locally on your Mac.

The application works by routing messages through Telegram's cloud to the Agent SDK, where Claude writes code and users approve every action. It uses long-polling routes and callbacks to bridge Telegram with the AI agent, providing streaming real-time responses with interactive permissions. The system operates with outbound-only connections and no exposed ports for security.

Benefits include full desktop access to files and tools, the ability to install, test, deploy, and debug code remotely, persistent project state management, and access from any device running Telegram including phones, tablets, laptops, and desktop computers. It enables natural Telegram-native conversations with smart context features where Claude reacts with emoji acknowledgments.

yottoCode targets developers and technical users who want mobile access to their development environment, particularly those using Claude Code subscriptions. It integrates with MCP servers for extended functionality including WhatsApp messaging, GSuite email/document management, Slack communications, Notion databases, Linear project tracking, and filesystem operations. The app requires macOS 14.0+ on Apple Silicon hardware.
