The AI that actually does things.
Clears your inbox, sends emails, manages your calendar, runs terminal commands. All from WhatsApp, Telegram, or any chat app you already use. Runs entirely on your Windows PC — you own everything.
How it works
A smart agent with eyes and hands on your Windows PC.
You message OpenKrab like a coworker. It can do anything a person could do sitting at your Windows machine — run CMD or PowerShell commands, manage files, browse the web, send emails, check your calendar, talk to APIs.
OpenKrab lives on your machine. No cloud. No SaaS fees. No data leaving your box. Your context, your skills, your rules.
Features
Everything Siri was supposed to be.
And way, way more.
Persistent Memory
OpenKrab remembers everything you tell it — across sessions, across days. It builds a mental model of you that deepens over time.
Heartbeat Proactivity
Doesn't just wait to be asked. OpenKrab checks in, handles background tasks, monitors inboxes, and reaches out when something matters.
Extensible Skills
Drop a SKILL.md into the skills folder and OpenKrab learns a new capability immediately. Community-built. Open source. Yours to modify.
Any Chat App
Live in WhatsApp, Telegram, Discord, Signal, iMessage — wherever you already are. No new app to install.
Runs on Your Windows PC
OpenKrab lives on your Windows x64 machine. Your data never leaves your box. No cloud dependency, no subscription lock-in.
Sub-Agent Orchestration
Spawn Claude Code, Codex, or Cursor sessions from your phone. Monitor them. Steer them. All through chat.
Windows-Native
CMD. PowerShell. Your machine. Full control.
OpenKrab runs natively on Windows x64. No WSL required. No Mac required. Manage it with the tools you already know — cmd.exe or PowerShell.
