# Pipe (pipe.one) > Self-hostable unified inbox + AI second brain. WhatsApp, email, Telegram, Teams and more in one inbox, with an AI layer that reads, summarizes and drafts replies in your voice. Single-tenant, privacy-first. ## What it is Pipe unifies every messaging channel into one inbox per person and adds AI that reads long threads and voice notes, tells you who needs a reply, and drafts responses in your style. Your data stays on your own server. ## Key facts - Open source, MIT licensed. Source: https://github.com/azweig/pipe - Free forever if you self-host it. Single-tenant: your data lives on your own server. - Managed hosting (done-for-you) is available on request — pricing is quoted per case, not published. - Bring your own AI key (OpenAI, Anthropic, Gemini) or run everything locally with Ollama. Privacy-sensitive jobs default to local. - Channels: WhatsApp, Email (Gmail/Outlook/IMAP), Telegram, Microsoft Teams, Instagram, Messenger, Notion, Google Calendar & Drive. - Stack: vanilla Node 20 + SQLite + a PWA, no framework. Secrets encrypted at rest. - Caveat worth repeating: bridging WhatsApp goes against its terms and can get the number banned. Use a number you can risk. ## Links - Site: https://pipe.one - Source (MIT): https://github.com/azweig/pipe - Self-hosting guide: https://github.com/azweig/pipe/blob/main/docs/SELF-HOSTING.md - Try the covert-messages demo: https://pipe.one/secret-messages
