AI competitor discovery: the brands AI really names
Proofsource's AI competitor discovery finds the brands AI engines such as ChatGPT, Perplexity and Gemini actually recommend in your category, not just the ones you already know. It proposes a starter set from your site and from real answers, checks each candidate's website, merges name variants, finds nearby competitors for local brands, and lets you confirm the list before tracking starts.

| Otter.ai | Named in 41 of 120 answers | Verified |
| Fireflies.ai | Named in 29 of 120 answers | Verified |
| Fathom | Same category on its site | Verified |

AI competitor discovery, explained
AI competitor discovery is finding out which brands AI answer engines recommend when buyers ask about your category. The list is often different from your sales team's list: engines may favor an older incumbent, a free tool, a marketplace or a brand you have never heard of.
Proofsource builds the list from evidence. It starts from your domain and market, adds the brands that real answers name, reads each candidate's website to confirm it is in your category, merges spelling and naming variants, and for brands with physical locations searches nearby. You confirm the final list, and you can ask Proofsource to re-derive it later from what engines say now.
How it works
Find the competitors AI engines actually recommend in your category, verified and deduplicated, including local ones.
Read your brand
Proofsource reads your site and market to understand the category.
Gather candidates
Candidates come from three sources: your market, your site and the brands AI answers name.
Verify each one
Each candidate's website is read and checked against your category; names are matched and deduplicated.
Add local competitors
For brands with locations, nearby competitors are found per place.
Confirm the list
You keep, remove or add competitors; tracking uses your confirmed list.

Every capability, live today
12 shipped capabilities behind AI competitor discovery, each in the product now.
Starter competitor set
Proposes a starter set of competitors for a new brand from its domain alone, drawing candidates from three sources so the list is not built on one guess.
Competitor selection
Picks the strongest candidates for your confirmed list, including the domains a buyer in your market would actually use.
Category check
Keeps out brands that are not in your category.
Website check
Reads what a proposed competitor's website is about before its words are shown as evidence. Each competitor is verified this way before it counts in your metrics, and a real competitor is never marked unverified just because a check ran out of time.
Name matching
Recognizes a competitor brand from its name and domain, and matches the different ways answers write its name, pulling out the company and product names an answer actually mentions.
Deduplication
Merges duplicate and variant brands into one competitor.
Competitors without websites
Checks competitors for brands that start from a store, app or map listing rather than a website.
Local search places
Chooses the places a local brand's map searches run for.
Nearby rings
Groups nearby competitors into rings by distance from a location.
Competitors per location
Runs competitor discovery for one location and tags the competitors near each of your locations.
Find competitors again
Re-derives your competitors and category from what AI engines say now.
Your confirmed list
Your list is stored as you confirmed it. When it is missing or wrong, Proofsource finds the competitors again before any work is spent.

Questions about AI competitor discovery
How does Proofsource find my competitors?
It reads your site and market, gathers candidates from three sources including the brands that real AI answers name, checks each candidate's website and category, merges duplicates, and shows you the list to confirm.
Can I add or remove competitors?
Yes. The list is yours to confirm, edit or extend at any time.
Why does AI name competitors I have never heard of?
Engines draw on review sites, lists and forums. A small brand cited often in those sources can appear in answers more than a larger one. Discovery surfaces these so you can track them.
Does it work for local businesses?
Yes. For brands with locations, Proofsource searches nearby competitors per location and groups them by distance.
What if my brand does not have a website?
Discovery also works for brands that start from a store, app or map listing.
Can I refresh the competitor list later?
Yes. Find competitors again re-derives the list and category from what engines say now.
How is this different from Rankscale or Writesonic?
Both suggest competitors automatically. Proofsource adds a website and category check on each candidate and shows the evidence behind every suggestion before you confirm it.
