Best AI tools for Detecting Dishonest Responses during Online Interviews
Explore the best AI tools like Sherlock and others that detect dishonest or AI-generated responses during live video interviews and prevent fraud.
The hiring process has quietly become one of the biggest victims of AI misuse.
Candidates now walk into interviews - or rather, video calls - with ChatGPT windows open, whispering prompts into hidden earbuds, or using deepfake overlays that mimic someone else’s face or voice.

What used to be a conversation about skills is now a cat-and-mouse game of truth vs. technology.
Recruiters know something is off. Candidates sound too fluent. Answers are too polished. There’s a pause before every response - almost as if a model is thinking, not a person.
This is the new hiring reality. And to restore trust, a new generation of AI integrity tools is emerging - built to detect dishonest responses, proxy participants, and AI-generated behavior in real time.
The Complication
Traditional proctoring tools were built for exams, not interviews.
They detect if someone left the tab - not if someone else is speaking on behalf of the candidate.
What makes dishonest responses in interviews particularly hard to detect is:
- Multi-modal deception - Candidates can fake not just answers, but tone, facial expressions, and even voice.
- Subtle AI assistance - People use earphones connected to another person or real-time GPT whispering tools.
- Deepfake overlays - Video masking tools can swap faces, making identity checks unreliable.
- Scripted responses - AI tools generate perfect yet context-misaligned answers that recruiters often mistake for competence.
These aren’t theoretical problems anymore. They’re showing up in day-to-day interviews across industries, especially in high-value remote hiring.
AI Tools Fighting Dishonesty in Interviews
Here are some of the most promising AI tools that detect dishonest responses during video interviews - each approaching the problem differently.
1. Sherlock
Best for: Hiring Managers and Recruiting teams who want an enterprise-grade, Forensic-grade AI proctor inside live interviews.

How it works:
Sherlock joins your Zoom, Teams, or Google Meet as an invisible AI agent. It watches for suspicious behavior - like mismatched lip movements, multiple faces, tab switches, whispering, or unusual speech latency - and flags potential fraud or AI-assisted responses.
It uses multi-modal analysis (video, audio, transcript) and builds behavioral signatures for every candidate.

Why it stands out:
Sherlock doesn’t just detect anomalies; it learns what honesty looks like for each user. It also auto-summarizes interviews and creates a “trust score” alongside the skill score.

Best for: Structured AI interviews and large-scale screening.
How it works:
HireVue uses AI to analyze verbal and non-verbal cues in candidate responses. It looks at tone, sentiment, pauses, and gaze direction to infer authenticity and engagement.
Limitation:
While powerful for structured one-way interviews, it’s less effective for real-time proxy fraud or deepfake detection.

Best for: Chat-based honesty detection.
How it works:
Sapia uses linguistic and psycholinguistic AI to detect unnatural writing patterns and AI-generated text in chat interviews.
It can spot over-optimized or “machine-styled” phrasing patterns that betray ChatGPT-type responses.

4. Reejig
Best for: Ethical AI scoring with fairness focus.
How it works:
Reejig builds ethical, auditable AI systems that help organizations identify skill patterns while ensuring bias-free evaluation. While not a fraud-detection tool per se, its explainable AI framework adds a trust layer to assessment analytics.

5. Deepware / Reality Defender
Best for: Detecting deepfakes and face-swaps.
How it works:
These tools scan live or recorded video streams for manipulation artifacts - pixel-level inconsistencies, temporal warping, and synthetic noise that indicate tampering.
They’re becoming a vital part of background verification and identity assurance stacks.


Best for: Identity verification in the hiring process.
How it works:
While not built for “dishonest response” detection, this tool ensures that the person interviewed is the same person whose credentials were submitted — closing the loop on identity fraud before interviews even begin.

The New Standard of Interview Integrity
The future of interviews isn’t about catching cheaters - it’s about re-establishing trust in conversations between humans.
AI will soon be present on both sides of the table - candidates using it to assist, companies using it to detect and interpret.
The right path isn’t paranoia; it’s precision.
By layering AI tools like Sherlock into your workflow, you can separate human honesty from machine fluency, ensuring that interviews remain what they were meant to be - a truthful exchange of competence, not computation.
TL;DR Summary
| Problem | Old Approach | AI Solution |
|---|---|---|
| Candidates using ChatGPT or proxies | Manual observation | Sherlock – AI agent in interviews |
| Deepfake overlays | Visual verification | Deepware / Reality Defender |
| Scripted AI responses | Text pattern detection | Sapia.ai |
| Identity mismatch | ID check post-submission | AuthBridge / IDfy |
| Unnatural pauses, voice inconsistency | None | HireVue / Sherlock |
In the age of AI, trust will become the ultimate hiring currency.
The companies that adopt AI integrity layers early won’t just prevent fraud — they’ll hire more confidently, scale faster, and protect the one thing that can’t be automated: human authenticity.
