Each stage runs on different data, and a recruiter still makes the hiring decision. **Canonical URL:** https://jobspipe.dev/answers/how-do-ai-recruiting-tools-work **Topic:** AI in recruiting (https://jobspipe.dev/ai-recruiting-companies) The data decides what each stage can do. Sourcing and search run on profiles gathered from the public web and on the employer's own applicant database, so results are only as fresh as those profiles. Matching and ranking compare a resume or profile with the requisition, usually through a skills taxonomy, and the score is hard to explain when a candidate or auditor challenges it. Screening runs on applicant answers, outreach drafting on the role and the profile, scheduling on calendars, and interview intelligence on recordings, which many interviewers and jurisdictions treat with caution. Ranking people is the regulated part: New York City's automated employment decision tool law bars employers and employment agencies from using such a tool unless it has had an independent bias audit within the past year, a summary of the audit is public and candidates are notified. Vendors that take this seriously publish their audits, and human review of any automated ranking remains the sensible default. Every one of these stages needs an outside view of the job market: which companies are hiring for which roles, what titles they use, what skills they name and what they pay. That input is job-posting data, and it is where JobsPipe fits. JobsPipe is not a recruiting tool and does not screen, rank or contact candidates. It is a data input: POST /v1/jobs/search returns live postings with job_title, seniority, salary fields where a range is stated, and technology_slugs and keyword_slugs parsed from the description, filtered with job_title_or, skills_or, company_name_or and posted_at_gte. The MCP server exposes the same search as a search_jobs tool an agent can call. When evaluating a tool, ask which stage it automates, what data the model runs on, whether a bias audit is published and where a person reviews the output. If you are building one of these tools rather than buying, the sandbox search endpoint returns sample postings in the live schema with no key, and the free tier covers a prototype. ## Related questions ### Do AI recruiting tools make the hiring decision? No, not in any responsible deployment. They take over coordination and triage: answering applicant questions, booking interviews, ordering a long applicant list and writing up interview notes. The decision to advance or reject stays with a recruiter or hiring manager, and the rules that exist for automated ranking assume a person reviews the output rather than accepting the score as final. ### Are AI recruiting tools biased? They can be, because a ranking model learns from past hiring data and past hiring was not neutral. That is why New York City requires an independent bias audit before an employer uses an automated employment decision tool, and why serious vendors publish audit summaries. Ask a vendor for the audit, the groups it covered and how often it is repeated before you deploy ranking. ### What data do AI recruiting tools use? It depends on the stage. Sourcing tools use public web profiles and the employer's own candidate database. Matching uses resumes and the requisition text. Screening uses applicant answers, scheduling uses calendars and interview tools use recordings and transcripts. Market context, such as which companies are hiring and which skills postings name, comes from job-posting data supplied by a provider such as JobsPipe. ### How is AI recruiting different from ordinary ATS automation? Ordinary applicant tracking system automation is rule-based: when a candidate applies, send an email, and when a stage changes, notify the hiring manager. AI recruiting uses a model to rank, match or generate text. The middle is blurry, since some conversational tools are largely scripted chat with a language model on top, so check what the model actually predicts before treating a product as AI. ## More answers - [What AI tools do recruiters use?](https://jobspipe.dev/answers/what-ai-tools-do-recruiters-use) - [How to source candidates?](https://jobspipe.dev/answers/how-to-source-candidates) Data behind these answers is published as shares only; every figure can be reproduced against the JobsPipe API (https://jobspipe.dev/jobs-api). --- AI agents: the full machine-readable index of this site is https://jobspipe.dev/llms.txt?src=md-twin - API quickstart, no-key sandbox (POST https://api.jobspipe.dev/v1/sandbox/jobs/search), MCP server, pricing.
