Self-Hosted AI Interview Software for Screening Calls
AI interview software from NeuralChainAI runs first-round screening calls with candidates by phone, asks your screening questions and writes a structured summary to the ATS for the recruiter. Speech-to-text, the language model and text-to-speech all run self-hosted on open-weight models in your own cloud account or on your servers, so call audio and transcripts stay inside the firm's environment.
What a Self-Hosted Screening Call Does
Six parts of a first-round screen, handled by a voice agent your recruiters configure and review.
Places and answers calls
Calls candidates at the booked time or takes inbound calls from a job ad, in a natural voice, and introduces itself as an AI assistant for your firm.
Asks your screening questions
Works through the questions for the role, such as availability, rate, location, work authorisation and must-have skills, and follows up on vague answers.
Writes a summary to the ATS
Answers, a short summary and the full transcript land on the candidate record in Bullhorn, Loxo, Recruit CRM or Greenhouse for the recruiter to review.
Books a recruiter call
At the end of the screen, the agent offers a slot from the recruiter's calendar, so every candidate speaks with a person next.
Self-hosted voice stack
Speech-to-text, an open-weight LLM and text-to-speech run on your GPUs or in your cloud account, and audio is stored under your own retention policy.
Disclosure, consent and review
Each call opens with an AI disclosure and recording consent. The agent records answers, and recruiters make the screening decision.
Why Firms Run AI Screening Calls on a Self-Hosted Voice Stack
Paradox, Manatal's AI Interviewer add-on and the voice AI features in platforms such as Greenhouse run AI interviews on the vendor's cloud and its model providers. Firms choose a self-hosted voice stack when one of these applies:
Screening calls on a voice stack you host.
Speech-to-text, the language model and text-to-speech run on open-weight models in your environment, on the same stack as our custom voice agents. Audio, transcripts and summaries are written to your storage and your ATS, under your access controls.
How We Build Self-Hosted AI Interview Software
Six pieces, from the screening script to the audit log, all running in the firm's own environment.
A screening script per role family
We turn your recruiters' screening questions into scripts per role family, with knock-out questions, follow-up prompts and the ATS field each answer fills.
Telephony and scheduling
Calls run over your telephony provider or SIP trunk. Candidates pick a slot from a link, or the agent calls at the booked time, with retries and voicemail handling.
Self-hosted speech-to-text
An open-weight speech recognition model runs on your GPUs, with your role vocabulary, such as skills, certifications and client names, supplied as context so transcripts read correctly.
Self-hosted LLM and text-to-speech
An open-weight LLM served with vLLM runs the conversation and writes the summary, and a self-hosted text-to-speech model gives the agent its voice. We tune latency for natural turn-taking.
ATS write-back
Answers, the summary, the transcript and a link to the recording are written to the candidate record, and the recruiter gets a review task.
Disclosure, consent and audit logs
Each call opens with an AI disclosure and recording consent. Calls, transcripts and recruiter decisions are logged, so the firm can answer candidate requests and support bias audits where a tool falls under rules such as NYC Local Law 144.

Hosted AI interview tools suit high-volume hiring where clients accept vendor-cloud processing of candidate audio. A self-hosted voice stack fits these cases:
A self-hosted voice stack gives recruiters a first-round summary for every candidate and keeps the audio, transcripts and decisions inside the firm.
Frequently Asked Questions on AI Interview Software
AI interview software runs part of a job interview with an AI system, usually a first-round screen by phone, video or chat, and records the answers for a recruiter. Ours handles phone screening calls on a self-hosted voice stack: it asks the role's screening questions, follows up on unclear answers and writes a structured summary to the ATS. A recruiter reviews every summary and makes the decision.
All three models run in the firm's environment: speech-to-text, the language model and text-to-speech, each an open-weight model on GPUs in your cloud account or on your servers. Call audio, transcripts and summaries are stored there too. Only the phone connection runs through your telephony carrier.
Yes. Each call opens with a disclosure that the caller is an AI assistant for the firm and asks for consent to record. Candidates can ask to speak with a recruiter at any point, and the agent books that call.
It depends on where candidates live and how the output is used. In New York City, a tool that substantially assists hiring decisions needs an independent bias audit within one year before use and 10 business days of candidate notice under Local Law 144. Colorado's SB 26-189 adds notice and explanation duties from January 1, 2027, and Quebec's private-sector privacy act requires telling a person when a decision is based exclusively on automated processing. Call-recording consent rules vary by state and province. Your counsel sets the policy, and the system logs what an audit needs.
Bullhorn, Loxo, Recruit CRM and Greenhouse through their APIs, plus other systems with an open API after scoping. The summary, answers, transcript and recording link land on the candidate record, and the recruiter gets a review task.
GPU capacity for the three voice models, the number of role families and scripts, call volume and the ATS integration. The build is a one-time cost, then hosting and an optional flat retainer. The models run on your compute, so call cost follows your own infrastructure.
