Competitor monitoring tool for the web and AI answers

A competitor monitoring tool collects what is said about your rivals so you notice their launches, complaints and wins early. MentionRadar tracks competitor mentions across news, blogs, forums, Reddit, review sites, YouTube and X, and records when AI engines recommend them instead of you.

Three things worth watching on every competitor

Most competitor monitoring fails because it tracks everything and highlights nothing. These three signals are the ones that change what your team does next.

Launches and announcements

A spike in news and blog mentions is usually a launch, a funding round, a pricing change or a partnership. Seeing it on the day gives sales a talking point and product marketing time to respond before prospects ask.

Complaints and churn signals

Negative mentions of a competitor on Reddit, forums and review sites show where their customers are unhappy: outages, support delays, price increases. Those threads are where buyers look for alternatives, and where your product is relevant.

AI recommendations

When ChatGPT or Perplexity recommends a rival for a question your product answers, you lose deals you never see. Tracking which competitors AI engines name, and in which position, shows where they are winning the shortlist.

A competitor launch, followed alert by alert

Tuesday, 09:30. A trade publication covers a new reporting feature from a competitor. The article has high reach, and the rule "competitor keyword, reach above 100k" posts it to the product marketing channel in Slack.

Tuesday afternoon. A Reddit thread asks whether the new feature is worth switching for. Several replies mention slow support. A negative rule on the same competitor sends it to email, and the team drafts a comparison page instead of a reply.

Thursday. The weekly AI run shows Perplexity now lists the competitor first for a reporting question, citing the launch article. Your brand drops one place. The response is clear: get the comparison page and a review of your own reporting feature in front of the same publications.

Setting up competitors so the data stays clean

  1. Pick the rivals buyers compare you with

    Use the names that come up in lost deals and in AI answers to your own prompts, not the biggest company in the market.

  2. Add exclusion words

    A competitor called Harbor or Atlas needs exclusions such as "port" or "maps" to keep unrelated mentions out of the feed and the share of voice.

  3. Narrow sources if needed

    Language and source filters keep a rival with a large consumer audience from flooding the feed with posts that do not matter to you.

  4. Write rules for the two moments that matter

    High reach coverage of a competitor for launches, negative mentions of a competitor for churn signals. Everything else goes to the daily digest.

  5. Add comparison prompts

    Prompts such as "your brand vs competitor" and "alternatives to competitor" show how AI engines position you against each rival.

From competitor mentions to decisions

Measure the balance

Individual mentions add up to a share of the conversation. The share of voice tool turns your competitor data into one web share, one AI share and a combined number per brand.

Follow the AI shortlist

Where a rival sits in AI answers over time is a ranking problem. The AI rank tracker shows your position next to theirs for every prompt and engine.

Read the threads

The most candid opinions about competitors live in community threads. See how Reddit monitoring catches the discussions where buyers ask for alternatives.

Questions about competitor monitoring

What does a competitor monitoring tool track?

It tracks public mentions of competitor brands and products: news coverage, blog posts, forum and Reddit threads, reviews, videos and posts on X. MentionRadar adds the AI side, recording which competitors ChatGPT, Gemini, Perplexity, Claude and Google AI Overviews name for the questions you track.

How many competitors can I monitor?

Starter includes 3 competitors, Growth 10, Agency 10 per client workspace and Enterprise 25 per workspace. Each competitor gets the same treatment as your own brand: mentions, sentiment, share of voice and presence in AI answers.

Can I get alerts when a competitor is mentioned?

Yes. Every plan sends email alerts and a daily digest. Growth and higher plans add Slack alerts and custom rules by keyword, sentiment, reach and source, so you can route negative mentions of a rival or high reach coverage of their launch to the right channel.

Does competitor monitoring need access to their accounts?

No. MentionRadar reads public sources and public AI answers only. It needs no login to any account, yours or a competitor's, and it never posts or replies on anyone's behalf.

Is it legal to monitor competitors this way?

Monitoring public coverage, public discussions and the answers of public AI engines is standard market research. MentionRadar collects what anyone could read on the open web and stores the link to the original source with every mention.

How is this different from a share of voice report?

Share of voice is one number per brand. Competitor monitoring is the stream behind it: the individual article, thread or AI answer that moved the number, with sentiment and reach, so you can act on a specific event rather than a percentage.

Scan your brand next to a competitor

Add one competitor to the scan. You see your recent web mentions and an AI engine answer that shows whether it names you, your rival or both, before you create an account.
