I'm building a tool to detect when competitors start showing up in AI answers

A good way to do this is to treat it like a share-of-answer monitoring problem, similar to brand tracking in search.

Core approach

1) Define a query set

Build a list of prompts people might ask that are relevant to your category.

Examples:

• “Best CRM for small teams”
• “What’s a good alternative to Salesforce?”
• “Which project management tool is best for agencies?”
• “Compare [your brand] vs [competitor]”
• “Top tools for [use case]”

Include:

• High-intent commercial queries
• Comparison queries
• Category-definition queries
• Problem/solution queries

2) Query multiple AI systems

Run the same prompts through:

• ChatGPT
• Claude
• Gemini
• Perplexity
• Copilot
• Any custom AI search/product you care about

For each response, capture:

• Whether your brand appears
• Whether competitors appear
• Position/order in the answer
• Sentiment/context
• Citations or links if present
• Whether the answer is a list, recommendation, or comparison

3) Extract entities from responses

Use an entity detection layer to identify:

• Brand names
• Product names
• Competitor names
• Category terms

You can do this with:

• Dictionary matching for known brands
• NER models
• LLM-based extraction for tougher cases

4) Score visibility

Track metrics like:

• Mention rate: % of answers where a competitor appears
• Your brand share: how often you appear vs competitors
• Rank/position share: first mention, top 3, etc.
• Context score: recommended, neutral, negative, comparison, excluded
• Answer type: listicle, direct recommendation, “it depends,” etc.

A simple example:

• Query: “Best invoicing software for freelancers”
• Answer mentions: FreshBooks, QuickBooks, Xero
• Your brand not mentioned
• Competitor visibility = 3/3
• Your share = 0%

5) Track trends over time

Store each run in a time series so you can detect:

• New competitor appearances
• Rising frequency of mention
• Changes after a model update
• Differences by model/provider
• Changes by geography/language if relevant

What to build technically

Pipeline

1. Prompt generator
2. Model runner
3. Response normalizer
4. Entity extractor
5. Scoring engine
6. Dashboard/alerts

Data model

For each result, store:

• prompt
• model/provider
• timestamp
• raw response
• extracted entities
• your brand mentioned? yes/no
• competitors mentioned
• ranking/order
• citations
• sentiment/context
• score

Alerting

Trigger alerts when:

• A new competitor appears in a key prompt
• Competitor mention rate increases above a threshold
• Your brand drops out of top recommendations
• A specific model starts favoring a competitor

---

Important caveats

1) AI answers are non-deterministic

The same prompt can produce different results. You’ll want:

• Multiple runs per prompt
• Averaged scores
• Confidence intervals

2) Prompt wording matters a lot

A small wording change can alter results. Keep:

• standardized prompts
• variants for same intent
• documentation of prompt versioning

3) Citations don’t always equal influence

Some systems cite sources, others don’t. A brand may appear without citation, or vice versa.

4) Competitor mention isn’t always bad

Sometimes appearing alongside competitors is positive if:

• you’re included in “top tools”
• the context is favorable
• the query is comparison-based

So track context, not just presence.

A practical MVP

If you want a fast first version:

• Choose 20–50 prompts
• Query 3–4 AI systems daily or weekly
• Save raw outputs
• Run brand/competitor name matching
• Display:
  • mention rate
  • top mentioned brands
  • trends by model
  • alerts for new mentions

---

Useful metrics

• AI Visibility Rate
• Competitor Share of Answer
• Your Brand Inclusion Rate
• Top-3 Mention Rate
• Category Coverage Rate
• Sentiment-weighted visibility

If you want, I can help you design:

1. a data schema,
2. a scoring formula, or
3. a Python pipeline for this tool.
