Snowball

Snowball is a web app and browser extension for creators who publish on X, formerly Twitter. It provides a distraction-free editor for posts and threads, an AI assistant that drafts content from a saved profile, and a library of templates. Posts can be placed in a queue and scheduled, including long posts for accounts with X Premium. Automation features repost earlier tweets and add a promotional reply, called an auto-plug, to posts that perform well. An engagement view filters the feed toward trending posts and lets users reply with AI help, and a dashboard tracks posting streaks and follower growth.

Snowball is aimed at founders, creators and small brands trying to grow an audience on X. Automated reposting and AI replies must follow X's automation and authenticity rules, and heavy automation can put an account at risk. Follower growth is not promised by any tool. Nothing was tested for this listing.

The pricing page lists Starter at $19, Creator at $39 and Pro at $69 per month, or $197, $397 and $697 billed yearly. New users get a 3-day free trial that requires a credit card, refunds are offered within 7 days, and unlimited AI features are subject to a fair use policy.
