Two things happen on every channel: Knock watches for the signals that matter, and — once you approve — it acts from your own account. Here's the full breakdown, platform by platform, with the caps that keep every one of them safe.
What Knock can watch and do on each channel. Every action runs from your own account, waits for your approval, and stays under human-paced daily caps.

Facebook connections stay to reactions, comments and Messenger — Knock never fires cold friend requests. Text is one-to-one from your own iPhone. Everything else runs in your own logged-in browser session — a lightweight extension on your laptop or computer.
Capabilities differ by platform, but the guarantees never do — every action runs from your real account, at a human pace, and only after you say go.
