@Anarc0byte I didn't know about SearXNG, thanks.

@edo84st I just built a B2B Executive Assistant on my homelab using OpenClaw + SearXNG. It lives on my personal WhatsApp, bypasses SaaS fees, reads my Google Calendar and books real meetings. OpenClaw solves the gap between "chatting with AI" and actually executing tasks.
