Use tool ↗About Apex - X Reply AI
Apex is a Chrome extension that automates replying to posts on X, formerly Twitter. It drafts responses matched to a voice profile trained on the user's own writing, and can reply automatically based on keyword triggers, a list of tracked accounts, or manual review before posting. It supports managing multiple X accounts from one dashboard and includes an analytics view for reply performance. The product connects through X's official API rather than storing account passwords. It is developed by Viral Automation Technologies. A free tier lets users try it without a credit card; paid Pro and Team tiers raise the number of connected accounts, though exact dollar prices were not shown on the pages checked during this research.

Pros & cons of Apex - X Reply AI
Apex handles the mechanical side of staying active on X: matching a trained voice, watching for keywords or specific accounts, and posting or queuing replies at a scale a person doing it manually couldn't match. Whether that's worth using depends on how comfortable you are automating public replies under your own account, since a bad automated reply is as visible as a good one.
Pros
- Trains a voice profile from the user's own writing rather than generic responses
- Supports keyword-based and account-based auto-reply rules
- Manages multiple X accounts from a single dashboard
- Uses X's official API instead of storing account credentials directly
Cons
- Exact subscription prices are not shown on the marketing pages; only account-count limits per tier are listed
- Automated public replies carry real reputational risk if the voice match or trigger rules misfire
- No country is disclosed for Viral Automation Technologies
Best for
- Accounts or brands that want to reply to many mentions or keyword matches on X without doing it manually
- Users managing multiple X accounts who want one dashboard for replies
- Teams that want reply activity backed by analytics
Not for
- Anyone who wants every reply personally reviewed before it's visible on their timeline
- Users uncomfortable granting an extension API-level access to their X account
Watch out: Automated replies post under your own account and are just as visible as manual ones; review the keyword and voice-training setup carefully before turning on full automation.
