The AI Behavior Index is the research arm of OneChat AI. This page focuses on the specific use case of AI for job application materials — resumes, cover letters, and related job search writing. It draws on multiple complementary surveys: candidate-side data from Greenhouse, iHire, and ResumeBuilder; hiring-side data from TopResume, ResumeBuilder, and iHire; and detection accuracy testing from ResumeBuilder's blind test of hiring managers.
Two important caveats. First, all candidate-side adoption numbers are self-reported and tend to undercount actual use (people don't always remember or admit to using AI). Second, the "outcomes" data (78% interview rate, 59% offer rate) is self-reported by candidates who used AI and may suffer from selection bias — candidates who had positive outcomes are more likely to attribute success to AI; candidates whose AI-assisted applications failed may discount AI as a factor. The gap between hiring manager confidence in detection (33.5% claim sub-20-second detection) and actual measured accuracy (18% correct in blind tests) is one of the most striking findings in this data. Data is refreshed when major surveys publish. If you have a study to suggest or notice an error, contact us at research@aibehaviorindex.org.
