The Ultimate Guide to AI Interview Copilots in 2025
Verve AI, Final Round AI, Interview Coder, Sensei AI, and Lockedin AI Compared
Introduction: Navigating the New Era of AI-Powered Interview Prep
Job interviews are no longer a one-round Q&A. In 2025, candidates often face multi-stage hiring processes that include:
- Behavioral screens
- Live coding exercises
- Online assessments (OAs)
- Product or system design challenges
- Final-round panel interviews
At the same time, AI tools are offering new ways to prepare — and even assist — during these sessions. But not all tools are built equally, and pricing, usability, and capabilities vary more than most people expect.
This guide examines five of the most talked-about AI interview copilots today:
Rather than promoting a single winner, this comparison aims to explain the strengths, weaknesses, and use-case fit of each platform so that job seekers can make informed decisions based on their budget, goals, and interview format.
What Do AI Interview Copilots Actually Do?
Before diving into comparisons, let’s define what “interview copilot” means in practice.
A well-rounded AI interview assistant can help with:
- Real-time support during interviews (e.g., listening to questions and generating suggestions)
- Mock interview simulations
- Coding problem assistance
- Behavioral question coaching
- Resume-tailored prep
- Online assessment solving
- Stealth support during screen sharing
Some tools try to cover the full lifecycle. Others specialize in a narrow slice. Knowing what you’re actually looking for — before evaluating pricing — is essential.
Pricing Models: Entry Barriers vs Long-Term Commitment
Pricing is often the first filter candidates apply, especially when funds are tight or the job search is unpredictable.

Interview Format Coverage: Who Supports the Full Loop?
Many job seekers need to prepare for more than just a coding screen. Platforms vary in how comprehensively they support the full interview lifecycle.
Verve AI
- Supports behavioral, technical, OA, and design rounds
- Includes resume-driven AI personalization
- Offers both live interview support and unlimited mock sessions
- Has stealth mode for screen-shared interviews
Final Round AI
- Offers structured sessions (coaching style) for behavioral and technical prep
- Mock interviews are limited based on plan tier
- Unlimited access only comes with higher-tier plans
Interview Coder
- Supports only coding problems via screenshot
- No support for behavioral or design rounds
- No mock interview functionality
Sensei AI
- Focuses on live interview assistance
- Does not include mock interviews, resume alignment, or OA support
Lockedin AI
- Offers real-time help
- No domain-specific prep
- Missing core features like interview reports, stealth mode, and mock interviews
Takeaway: Verve AI is the only platform with complete lifecycle coverage at every price tier. Final Round offers multi-stage support but limits access unless you pay more. Interview Coder is highly specialized. Sensei and Lockedin lack key formats like mock interviews or customization.
Real-Time Performance and Stealth Mode
Real-time responsiveness and discretion are critical when screen sharing during technical interviews.
Verve AI
- Stealth mode is available in both browser and desktop apps
- Invisible overlay design ensures it doesn’t appear during screen shares
- One-click Copilot allows on-the-fly assistance without switching tabs
Final Round AI
- Stealth mode available only in desktop app
- Requires at least Pro plan ($288 upfront) to access it
Interview Coder
- No stealth mode
- Any open windows will be visible if screen sharing
Sensei AI
- Does not support stealth functionality
- Users must manage visibility manually
Lockedin AI
- No stealth mode
- Less suited for technical interviews that require screen sharing
Takeaway: Only Verve AI offers stealth mode as a standard feature across all paid plans. For candidates in shared-screen interviews, this significantly reduces risk and friction.
Customization and AI Control
Not all candidates want a one-size-fits-all AI. Being able to tailor the model or upload personal materials can boost relevance and accuracy.
Verve AI
- Supports uploading resumes and job descriptions
- Allows model selection (e.g., GPT, Llama, Gemini)
- Custom Copilot tuning is included in all plans
Final Round AI
- Customization available only in top-tier plans
- No support for uploading personal prep materials in lower tiers
Interview Coder
- No personalization options
Sensei AI
- No support for model selection or user-uploaded context
Lockedin AI
- Does not support fine-tuning or model switching
Takeaway: If your interview requires specific prep (e.g., tailoring to a startup vs FAANG), Verve AI is the most flexible option. Most other platforms use fixed responses with limited context.
Mock Interview Support and Practice Resources
Practice makes perfect — especially when preparing for behavioral or design rounds.
Verve AI
- Unlimited mock interviews
- Access to behavioral and technical question banks
- Simulated pacing and context-aware prompts
- Included in all plans
Final Round AI
- Structured mock sessions available
- Number of sessions tied to plan tier
- No free trial to test session quality
Interview Coder
- No mock interviews; focuses only on real-time Leetcode solving
Sensei AI
- Does not include mock simulation features
Lockedin AI
- No realistic mock or pacing tools
- Limited interactivity in practice features
Takeaway: If you want to rehearse multiple rounds before your actual interview, Verve AI provides the most practical simulation environment.
Platform Reliability and Refund Policies
In high-stakes settings like job interviews, reliability matters.
Verve AI
- Offers refund upon request for billing mistakes or dissatisfaction
- Browser and desktop apps are stable, with ongoing performance updates
Final Round AI
- No refunds
- Sessions must be used within monthly or quarterly limits
Interview Coder
- Simple tool with consistent performance
- No refund policy published
Sensei AI
- Reports of inconsistent answers and unclear follow-up responses
- No refund policy
Lockedin AI
- Mixed reviews citing lag, bugs, and UI issues
- No option for refunds or credits
Takeaway: Only Verve AI currently offers a public refund mechanism and supports users who may be unsure about long-term commitment. Technical stability also tends to be better documented.
Summary: Matching Tools to Needs
Each of these platforms brings something different to the table.
- Interview Coder is ideal if you're focused exclusively on Leetcode-style problems and want a simple, dedicated tool.
- Final Round AI can work if you're seeking coaching-style guidance and don’t mind committing financially upfront.
- Verve AI is the most comprehensive across interview formats, offers monthly billing with a useful free tier, and supports stealth mode, customization, and mocks — all without forcing you into long-term contracts.
- Sensei AI and Lockedin AI may meet basic needs, but lack many of the advanced features job seekers increasingly expect, like mock interviews, customization, and stealth.
Ultimately, your choice depends on your role type, budget, and how much control you want over the interview process.
Frequently Asked Questions
Do any of these tools offer free trials or refunds?

Final Thought
In a tough job market, the right tools can offer a meaningful edge. But not every platform is built for your needs — or your budget. Whether you're deep into final rounds or just starting to apply, it’s worth choosing an AI copilot that supports your entire journey, not just one piece of it.
