Short answer: X (Twitter) can't notify you when someone tweets a keyword. Saved searches and X Pro columns only show results while you're looking. Building on the X API means paying for metered access and writing your own filtering. For actual alerts you need a monitoring tool: KWatch.io is the cheapest at $19/month for 2 X keywords, and Updately checks X hourly, scores each tweet for relevance and sentiment, and sends it to Slack, Discord or email, alongside LinkedIn and Reddit, from $49/month ($39/month billed annually).

Does X have keyword alerts?
No. X notifies you about your own @mentions, replies, and accounts you've turned notifications on for. There's no setting that says "tell me whenever anyone tweets this phrase."
That gap matters most for the tweets you'd actually want to catch:
- Untagged brand mentions. People write your name without the @, so you never get a notification.
- Competitor complaints. "Thinking of cancelling [competitor]" is never addressed to you.
- Buying questions. "Anyone know a good tool for…?" is worth most in the first hour, while the replies are still coming in.
Free and native options
Saved searches
On X you can run a search, sort by Latest and save it, so the same query is one click away next time. It's useful as a bookmark. It isn't an alert: nothing is pushed to you, and you only see new tweets when you remember to open it.
X Pro (formerly TweetDeck)
X Pro lets you pin a column per search, and each column updates live. It's the closest thing to native monitoring.
- Cost: it comes with an X Premium subscription.
- Limits: no notifications, no filtering beyond your search operators, no export. It works only while someone has the screen open.
Manual search routine
A daily routine of five saved searches, each sorted by Latest, takes about ten minutes. It's a reasonable start for one person with a handful of terms. It stops working when you need coverage overnight, across a team, or for more than a few keywords.
Why the X API isn't a shortcut
Developers' first instinct is to write a script against the X API that runs a search every few minutes and posts results to Slack. Three problems:
- Access is paid and metered. You pay for API access and you're rate-limited, so polling many keywords often gets expensive quickly.
- The search is only the start. You still need deduplication, exclusion of bots and giveaways, relevance filtering and delivery.
- It needs maintenance. Pricing, limits and endpoints for the X API have changed repeatedly, and every change is now your problem.
For one engineer monitoring one brand name, it can be a fun weekend project. For a team that wants reliable alerts, a tool that already pays for and maintains the data access is cheaper.
Zapier, IFTTT and other automations
No-code automation tools look like an easy answer: "new tweet matching search → send Slack message." In practice:
- They depend on X's paid API too. Since X began charging for API access, some automation services have limited or dropped their X triggers. Check what your plan currently supports before you build on it.
- They poll on a schedule set by your plan, so alerts can lag.
- They match keywords, nothing more. There's no relevance or sentiment scoring, so every giveaway and bot reply that contains your keyword lands in Slack.
- They count tasks. On busy keywords, each matching tweet uses a task, and the bill grows with the noise.
Automations are good at the last step: moving an alert from a monitoring tool into your CRM or a spreadsheet. They're weak at being the monitoring tool.

- PR and reputation reporting: Brand24.
With Updately you can also query tweets from Claude. Add https://api.updately.ai/mcp as a custom connector and ask something like "What did people say about [competitor] on X this week?" The MCP docs cover setup.
X advanced search operators for alerts
Whatever tool you use, the query decides whether alerts are useful. These operators work in X search (and at x.com/search-advanced), and most monitoring tools accept the same logic.
| Operator | Example | What it does |
|---|---|---|
"exact phrase" | "social listening tool" | Matches the phrase, not the words scattered through a tweet |
OR | (hubspot OR salesforce) alternative | Matches either term |
-word | "updately" -giveaway -hiring | Excludes tweets containing a word |
from: | -from:updately | Excludes (or limits to) one account |
to: | to:competitor | Replies sent to an account, often support complaints |
@ | @competitor cancel | Tweets mentioning an account |
lang: | lang:en | Limits to one language |
min_faves: | min_faves:10 | Only tweets with at least 10 likes |
filter:links | -filter:links | Excludes tweets with links, which cuts a lot of promotion |
filter:replies | -filter:replies | Original tweets only |
since: / until: | since:2026-10-01 | Date range, for testing a query against recent history |
Queries worth saving:
- Untagged brand mentions:
"yourbrand" -from:yourhandle -filter:links lang:en - Competitor complaints:
"[competitor]" (down OR broken OR cancel OR "switching from") - Competitor support traffic:
to:[competitor] (refund OR cancel OR "doesn't work") - Buying questions:
("looking for" OR "any recommendations" OR "anyone use") "[your category]" -filter:links - Alternative hunting:
"[competitor] alternative" OR "alternative to [competitor]"
Test each query in X search, sorted by Latest, before turning it into an alert. If the first page is mostly noise, an alert will be too.
How to set up a Twitter keyword alert
- Write three to five queries from the list above: brand, competitors and buying intent.
- Test them in X search with
since:set to last week and adjust exclusions until most results are relevant. - Add them to your tool as keywords or listeners. In Updately, add LinkedIn and Reddit to the same listener if your buyers are there too.
- Route by urgency. Buying questions and brand complaints go to real-time Slack or Discord. Competitor mentions go to a daily email digest. See real-time social listening alerts for a routing table.
- Reply fast and plainly. A useful answer in the first hour beats a pitch the next day. Say who you are.
- Prune after a week. Remove queries that produced nothing you acted on.
FAQ
Can I get an alert when someone tweets a specific word?
Not from X itself. You need a monitoring tool such as Updately, KWatch.io, Syften, Octolens or Brand24, which runs the search continuously and alerts you by email, Slack or Discord.
Is there a free Twitter keyword alert tool?
Not a fully automated one, because X's API is paid. The closest free-ish options are saved searches and X Pro columns (with X Premium), which you have to check yourself, or the free trials of paid tools.
Does TweetDeck still exist?
It's now X Pro, and it needs an X Premium subscription. Search columns update live, but it doesn't send notifications.
How fast are Twitter keyword alerts?
It depends on the tool and plan. Updately and Octolens Pro check X hourly; Octolens Scale and Brand24 Pro are real time; Brand24's entry plan updates every 12 hours.
Can I get X and LinkedIn alerts in one tool?
Yes. Updately, KWatch.io and Octolens cover both. For LinkedIn specifically, see LinkedIn keyword alerts. For Reddit in Slack, see Reddit alerts in Slack.
