Comment automation

Comment automation lets you define rules that act on incoming comments without a human in the loop. Each rule watches a specific post (or account), matches comments against keywords, and responds — with a public reply, a DM, or both.

How a rule works​

A rule has:

  • Scope — the post or account it applies to.
  • Trigger — keyword(s) to match against the comment text.
  • Action — what happens on a match:
    • Reply — post a public comment reply.
    • DM — send a direct message to the commenter.
    • Both — reply publicly, then DM.

When a comment arrives (via webhook for real-time platforms, or polling otherwise), post.buzz evaluates the matching rules and fires the configured action. Every fired rule is logged in an automation log so you can audit what was sent and when.

Supported platforms​

The full listen → match → reply/DM loop works on:

Instagram, Facebook, Threads, X, YouTube, TikTok, LinkedIn.

DM delivery is more restricted — see the capability matrix for which platforms support sendDm.

Common patterns​

  • "Comment 'LINK' to get the link" — match the keyword, DM the resource. The classic lead-gen pattern.
  • FAQ deflection — auto-reply to "price"/"pricing"/"how much" with a pointer to your pricing page.
  • Engagement bumps — auto-like every comment to boost visibility.

Limits and safety​

  • Rules run inside the platform's rate and spam limits. Aggressive automation can get an action blocked — pace your replies.
  • Each fired automation is recorded; review the log periodically to catch unintended matches (e.g. a keyword matching part of a longer word).
  • Automation never edits or deletes the commenter's original message.
