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

The app offers interactive permissions via inline keyboards, session resume with full history, model switching between Haiku, Sonnet, and Opus, MCP server integration, and live cost tracking. It supports voice input and output with local Whisper transcription, real-time streaming responses, file sharing, and screenshot capabilities. Users can send voice notes, photos, and documents directly through Telegram.

yottoCode works by routing messages through Telegram's cloud to the Agent SDK, where Claude writes code and users approve actions through interactive permissions. The system uses long-polling APIs and callbacks to bridge Telegram with the Claude AI agent, providing streaming real-time responses without exposing ports. Each bot instance handles one project directory, with a multi-bot launcher available for managing multiple projects simultaneously.

The product enables coding tasks like fixing bugs, compiling code, pushing to repositories, and managing development workflows. It also supports broader assistant functions through MCP integration, including managing messages, emails, documents, calendars, Slack communications, Notion databases, and file organization. Users can work with their actual development environment, files, and tools rather than sandboxed containers.

yottoCode targets developers and technical users who want mobile access to their coding environment, particularly those using Claude Code subscriptions. It's designed for macOS users with Apple Silicon devices running macOS 14.0+ who need to manage coding projects from multiple devices through Telegram's cross-platform availability.
