Extruct AI | Company Research API for AI Studio Work — Full 2026 Guide

Semantic Search

Turn a written ICP into a sourced candidate list without manual filtering.

Lookalike Search

Find companies similar to a target company. Lookalike search is listed alongside semantic search in every plan, from Free through Pro.

Sourcing companies from plain-English criteria

Extruct AI's Semantic Search finds companies from plain-English prompts, drawing on a curated 10M-company index or the live web. The site's own example asks for commercial HVAC contractors in Florida that primarily serve hospitals and school districts, have 50+ employees, completed a $5M+ project in the last 12 months, have BIM/Revit capability, and are hiring engineers — a run that sourced 2,438 candidates and returned 112 high-fit matches in 5m 11s. Every answer comes back with its source.

Finding lookalikes of a target company

Lookalike Search finds companies similar to a target company, using 1 credit per search on the Free, Starter, and Pro plans. It sits alongside Semantic Search as one of the two core search modes, and on Starter and Pro each supports up to 2,000 results per search.

Multi-criteria screening with Deep Search

Deep Search checks multiple criteria and returns fewer, higher-fit matches, costing 2 credits per match. It is available on the Pro plan with 1,000 matches and 100 results per deep search, and is positioned for teams that need deeper workflows than plain search.

Building research tables and contact lists

On Pro, AI research tables cover 2,000 cells at 1 credit each, email lookups cover 500 lookups at 4 credits each, and phone lookups cover 100 lookups at 20 credits each. Results can be exported from public Data Rooms, shared as tables and searches, and pushed into a CRM — True Capital's Owen Eddershaw describes typing what they want, having it build the list, research everything, and drop it in Affinity CRM.
