About

GrowX is a Chrome extension for creators and others managing an audience on X (Twitter). It combines audience discovery and paced auto-follow tools with a 1–99 follow-back score, filters, and cleanup for accounts that do not follow back or appear inactive. Users can compose and schedule posts and threads, organize drafts and queue slots, and review engagement analytics, effective topics, and posting times. The extension tracks new followers and unfollowers, surfaces recent posts from selected accounts for replies, and offers daily goals and account workspaces. Its on-device writer suggests ideas, hooks, rewrites, and threads. GrowX works through the user's signed-in X session in Chrome and does not require an X password or API key. A free plan includes core discovery, queue, analytics, backup, and cleanup tools. A 30-day Premium trial is available, with account signup required and no payment card required to start.

About

Post Once is a social media cross-posting and content-backup service for creators, small teams, and agencies managing multiple accounts. Users publish from a connected source account in its social platform's own app; Post Once automatically reposts new videos and photos, with captions, to destinations including Instagram, YouTube, Facebook Pages, Threads, X, and LinkedIn. Stories can be reposted between Instagram and Facebook Pages. Videos up to two hours and 4K are supported, with long videos routed to YouTube, Facebook, and LinkedIn. Posts, videos, and Stories can be backed up to Google Drive, Dropbox, Backblaze B2, or Amazon S3; captions are saved with posts and videos. The dashboard holds likely repeat posts for review to help prevent duplicates. The free plan includes 10 reposts and 10 backups; paid plans start at $9/month. Higher tiers support more source accounts and unlimited backups.
