AI phone screening software calls your candidates, asks a consistent set of questions, and returns a transcript, a score, and a recommendation, so recruiters can skip the repetitive first-round call. The tools differ in format (voice, chat, or video), who they are built for (high-volume frontline versus professional roles), and how much control you keep over the questions.
Quick answer: For a simple AI phone screen where you approve the questions and get a transcript, rating, and recommendation per candidate, use Nova Interviewer. Ribbon is a strong voice option for high-volume hiring with ATS integration. HireVue is enterprise video interviewing plus assessments. Paradox (Olivia) is chat-based, best for high-volume frontline hiring. Outhire pairs phone screens with sourcing.
Voice, chat, or video?
The category splits by format. Voice tools call the candidate and hold a spoken conversation; chat tools screen over SMS or web chat; video tools ask candidates to record answers. Voice and chat tend to see higher completion than one-way video because they are lower-friction for the candidate. Which format fits depends on the role and your volume.

The distinguishing point is control and simplicity: you decide the questions, and you get a clear, documented result per candidate without an enterprise rollout. It is free to start.

It is aimed at high-volume hiring in retail, logistics, healthcare, and staffing, and it includes fraud-detection features. A strong choice when you are screening hundreds of applicants and need ATS integration.
3. HireVue - best for enterprise assessments
HireVue is an enterprise hiring platform built around video interviewing and skills assessments, including game-based, coding, and language tests, plus an AI interviewer and scheduling. Its customers are large organizations, and pricing is custom via demo. It fits enterprises that want validated assessments at scale more than teams that just want a quick phone screen.
4. Paradox (Olivia) - best for high-volume frontline chat hiring
Paradox's assistant Olivia is a conversational recruiting tool that screens and schedules over text, SMS, and chat, and extends into onboarding. It is mobile-first and built for high-volume frontline hiring in retail, restaurants, and similar industries. Note that it screens by chat rather than a spoken voice interview, which suits some roles better than others.
5. Outhire - best for sourcing plus screening
Outhire's assistant, Joel, conducts AI phone screens around the clock and pairs them with resume evaluation and sourcing from a large candidate database. It is a fit when you want sourcing and screening handled together rather than as separate tools. Pricing starts at roughly $899 per month.
