Open-source Chief of Staff in a box. Opinionated, proactive, runs on your own infra.

CoSinaBox is a self-hosted AI Chief of Staff agent that runs your day. It ships with default morning briefing, pre-meeting prep, evening wrap, weekly review, and follow-up tracking. You configure who it's for, not what it does.

Key Features

• 5 built-in jobs: morning briefing, pre-meeting prep, evening wrap, weekly review, follow-up nudges
• Telegram-first: primary interface via Telegram bot
• Google integration: Calendar, Gmail, Drive (optional)
• SQLite memory: persistent context without external databases
• Zero telemetry: runs entirely on your infra with your API keys
• Extensible: add custom jobs via a thin user repo

Prerequisites

• Python 3.11+
• Anthropic API key (Claude powers the agent)
• Telegram bot token (via @BotFather)
• Optional: Google OAuth credentials (for Calendar/Gmail/Drive)
• Optional: Fireflies API key (for meeting transcripts)

Architecture

CoSinaBox follows an engine + thin user repo pattern (similar to Hugo + content, or Next.js + app code):

• Engine (cosinabox package): the agent loop, scheduling, tools, and built-in jobs
• User repo (scaffolded by cosinabox init): your personality, stakeholders, integrations config, and optional custom jobs

For detailed architecture, see docs/specs/2026-04-11-cosinabox-design.md.

Privacy

• Zero telemetry by default -- no data leaves your machine except to APIs you explicitly configure
• AGPL-3.0 license to protect against SaaS extraction without contribution
• README documents every external service the engine touches
