NinjaPoster

NinjaPoster is a Chrome extension and web app that posts to many Facebook groups for you. It also posts to groups where you're only a regular member, so you don't need admin rights. You pick groups or saved group lists, write a post or have AI write it, attach media, set delays and schedule it. The extension then posts to one group at a time from your logged-in browser session. It doesn't need your Facebook password.

To keep posts from being identical across groups, it rewrites each one with spintax and AI. It also adds delays between posts and can pause on its own. Other features include sharing new RSS feed items to groups, adding a link as the first comment after a delay, recurring campaigns, a media library, scheduling from your phone, and live logs showing which posts worked and which failed.

It's aimed at marketers, agencies, e-commerce sellers, real estate agents, coaches, local businesses and bloggers. It costs $37 a month with all features included. You can get a refund on the first payment within 7 days. The site says it isn't affiliated with Meta, and it warns that heavy use can still run into Facebook's limits.
