The recruiters use case, in detail.
Recruiters have an interesting tradeoff: in many roles, AI-assisted writing in a cover letter is acceptable or even expected (writing is a tool, not a competency for most jobs). The harder cases are roles where written work is itself the deliverable — content marketing, strategy consulting, technical writing, journalism. For these roles, AI detection in the candidate funnel is genuinely diagnostic. AI Checker recommends a clear policy: communicate to candidates that submitted writing samples will be screened, treat high AI scores as a flag for follow-up rather than auto-rejection, and probe authorship in the interview rather than assuming it. Many strong candidates use AI assistance for editing — that's different from AI authorship, and the sentence-level breakdown is essential for distinguishing the two.
Frequently asked questions
Is AI Checker free for recruiters?
Yes. AI Checker has a free tier built for recruiters with no signup required. Higher-volume usage and team features are available on paid plans.

Will my submitted text stay private?
Yes. Text submitted to AI Checker is processed in memory and is not used to train models. We do not sell or share content. Free tier submissions are not stored beyond the analysis itself.
Does AI Checker have an API for this workflow?
Yes. A REST API is available on all tiers — including the free tier with rate limits. Documentation includes example clients for TypeScript, Python, Go, and Rust.
What about false positives?
False positive rate on real human writing is approximately 1-2% across detection benchmarks. We surface this transparently — every result includes a confidence indicator. Catching AI-generated cover letters and take-home assessments in hiring funnels.
