# GroupBlaster

> GroupBlaster is a Chrome extension that finds your Facebook Groups and publishes one post to many of them — with spintax wording variations, a review step before anything goes out, and optional scheduling.

Key facts:
- Free plan: 5 campaigns and 10 posts a month — you fill in each group yourself and press Publish; paid plans add automatic publishing, scheduling, and randomized pacing.
- Sign in with Google to create a campaign or start a run — scanning your groups needs no account.
- Nothing is published without your approval, and consecutive posts are always at least 15 seconds apart.
- Spintax alternatives are written by you — GroupBlaster does no AI rewriting. A ChatGPT button can open your draft so you write the variations yourself.
