Find competitors with Google Sheets
Get the top 100 competitors, look-alikes, and similar companies for any domain in Google Sheets — ranked with match scores, relationship types, and confidence, powered by SimilarIQ's AI research engine. One key, ~60 seconds to first result.
Quick start
Add a custom =SIMILARIQ() function via Apps Script (Extensions → Apps Script):
const API_KEY = "sk-live-your-api-key";
function SIMILARIQ(domain, limit) {{
const res = UrlFetchApp.fetch("https://similariq.ai/api/v1/search", {{
method: "post",
contentType: "application/json",
headers: {{ "X-API-Key": API_KEY }},
payload: JSON.stringify({{ domain: domain, limit: limit || 25 }}),
}});
const data = JSON.parse(res.getContentText());
return [["Rank", "Company", "Domain", "Score", "Type", "Confidence"]].concat(
data.competitors.map(c => [c.rank, c.company, c.domain, c.matchScore, c.type, c.confidence])
);
}}Then in any cell: =SIMILARIQ("salesforce.com", 25) — the ranked competitor table spills right into the sheet. Tip: results also live in your My Companies workspace, exportable as CSV from the app any time.

}Frequently asked questions
What does SimilarIQ return for a domain?
The top 100 competitors, look-alikes, and similar companies for any company website — each with a 0-100 match score, relationship type (Direct, Indirect, Adjacent, Emerging), a confidence score, and a likely-competitor flag. Results come from SimilarIQ's proprietary AI research engine, cross-validated across multiple intelligence sources.
How much does it cost?
1 credit per search (up to 100 results). Credits come with plans from $6/month ($0.10-$0.24 per search) or pay-as-you-go at $0.50 per search. Free trial searches on signup. Failed searches auto-refund, and reading past results is always free.
How do I get an API key?
Sign up at similariq.ai, then create a key under API Keys in the app. The same sk-live- key works for the REST API, SDKs, CLI, and MCP server.
How long does a search take in Google Sheets?
30-60 seconds — the engine researches the domain live across multiple intelligence sources and cross-validates before ranking. Set your HTTP timeout to at least 120 seconds, or use the bulk endpoints for large lists.
