Find Instagram accounts similar to any profile - competitors and lookalike creators ranked by match score, with bios, follower counts and contact details.
An connector that finds Instagram accounts similar to a given profile by inferring the seed account's niche, audience and type from its bio and recent captions, collecting candidate accounts from Instagram suggestions and niche searches, and scoring each candidate for similarity. For each match it returns a numeric similarity score (0–100), a classified relationship to the seed account (direct competitor, similar creator, adjacent, or audience overlap), a concise plain-English reason explaining the match, shared thematic traits, and account metadata including profile text, category, location, audience size metrics, verification/business/private status, public contact details when listed, discovery provenance, and size metrics. The connector follows the strongest matches to discover additional lookalikes, ranks results by match strength, and supports filtering by similarity thresholds and audience-size ranges to target specific tiers of creators or brands.
