# X (Twitter) monitoring: keyword alerts for your brand mentions

Twitter keyword alerts without watching the feed: every post and reply on X that names your product, your competitors or your space, scored by AI within the hour and delivered where you work.

Every hourPosts and repliesThe official API

## Exactly what you get, no marketing numbers

Developers complain, compare and recommend on X first. A reply thread about your pricing is a churn signal hours before a support ticket, and a Twitter monitoring tool that only watches your handle misses the posts that never tag you.

What we watch

### Posts and replies

Public posts that contain your keyword, replies included, with the author, their follower count and the post a reply answers.

How often

### Every hour

Each keyword is searched once an hour. Cadence is a latency knob here, not a coverage one: a longer gap finds the same posts, later.

Where it comes from

### The official API

X API v2 recent search where it is enabled, a licensed data provider otherwise. Nothing outside the adapter knows which answered.

## X mentions, as Mentio delivers them

Every match is scored 0 to 100 for relevance against your company context, tagged with sentiment and intent, and summarised in a line. The same shape reaches Slack, a webhook, the API and your agent.

An illustrative mention for a fictional brand, acme.

We're moving off acme. The new pricing tiers pushed us over the edge, so we're evaluating alternatives this week.

## From post to signal in three steps

01

### Track keywords

Your brand, your competitors, your space. One POST per term, or a click in the dashboard.

02

### The pipeline watches everything

Every source is ingested once, matched against your terms, and classified by AI: relevance 0 to 100, sentiment, and intent, tuned by your company context.

03

### Act on what matters

Triage in the dashboard, deliver to Slack or webhooks, query the REST API, or let your AI agent work the feed over MCP.

## X monitoring questions

### What is a free tool for monitoring Twitter mentions?

Mentio starts every account with $5.80 of credit and no card: one keyword for a month plus 100 mentions, on X and nine other platforms. After that it is $5 per keyword per month and $0.008 per matched mention, with no subscription to cancel.

### What replaced TweetDeck for keyword alerts?

TweetDeck became X Pro, a paid column view you still have to watch. Mentio watches for you: each keyword is searched every hour through the official X API, and only the posts that matter reach Slack, Telegram, email, a webhook or your AI agent.

### Can I get Twitter keyword alerts in Slack?

Yes. Connect Slack once and each alert rule posts matching mentions as they arrive, with the author, their follower count, the AI relevance score and a mute button for the author. Lower-volume keywords can go out as a daily digest instead.

### Does Mentio use the official X API?

Yes. X API v2 recent search where it is enabled, a licensed data provider otherwise, and nothing outside the adapter knows which answered. Replies arrive with the post they answer, so the thread reads in context.

### Is there an X (Twitter) MCP server for brand mentions?

Mentio is one. Its MCP server gives Claude, Cursor, Codex and any other MCP client tools to search, filter and triage X mentions next to the other nine platforms, so an agent can pull this week's negative posts about your product and draft the replies.

### How often is X checked?

Every hour, per keyword. The cadence only sets latency: a longer gap finds the same posts, later. Every matched post is scored for relevance, sentiment and intent before anything is delivered.
