Two Different Workflows Call Themselves "Interview AI"
OphyAI's current UK pricing page describes a real-time Interview Copilot that listens during a live interview and provides suggestions in a discreet overlay. Its free plan includes one Copilot session capped at 15 minutes. Paid plans start at £22/month.
No reliable evidence supports a universal employer AI policy. CodeSignal's Certified Assessment rules limit outside help to syntax reference. HackerRank lets employers enable interview integrity signals for activity such as repeated tab switching, copy-paste and window resizing. Those are two platform examples, not universal employer rules.
The other workflow is AI interview practice: mock interviews before the call, recorded feedback and STAR-method scaffolding. Yoodli and ApplyArc fit this category rather than providing hidden live answers.
This page compares four live-copilot alternatives, one practice product and ApplyArc's practice-first option using documented workflows and current official pricing.
Practice with feedback lets you test examples, remove weak details and rehearse follow-up questions in your own words. It does not guarantee an offer, but the work remains useful across interviews.

OphyAI: Live Copilot With UK Pricing
Pricing: Free first Copilot session capped at 15 minutes; Pro £22/month; Premium £45/month.
Documented scope: OphyAI says Interview Copilot provides suggestions and follow-up prompts in a discreet overlay. Its separate Coding Interview product is included on Premium.
Trade-off: The UK page gives clear plan and credit details. Permitted use still depends on the employer's instructions and the assessment environment.

Final Round AI: Three Billing Commitments
Pricing: $90 month to month, $60/month billed quarterly or $25/month billed annually.
Documented scope: Final Round AI lists Interview Copilot for live assistance, AI Mock Interview for practice and post-interview analytics. Its pricing page says Stealth Mode is limited to specific paid tiers.
Trade-off: The monthly plan is non-refundable. Quarterly and annual plans require upfront payment and have a three-day refund window.

The dirty secret: ATS don't reject you, they rank you. One specific bullet beats a perfect keyword score. Fix that first, then pick the right tool.

Pricing: Free; Pro $19.99/month or $11.99/month billed annually.
Documented scope: Cluely describes itself as an AI meeting assistant that listens in real time and provides answers, notes and next steps. Its site calls the product undetectable. That is the vendor's claim, not permission from an employer.
Trade-off: The workflow extends beyond interviews. The annual rate requires a longer billing commitment than the monthly plan.

Sensei AI: Free, Monthly and Annual Plans
Pricing: Free; Pro $89/month or $24/month billed annually.
Documented scope: Sensei markets real-time answers, 30+ languages, coding support and integrations with Zoom, Microsoft Teams and Google Meet.
Trade-off: Sensei's own page makes strong outcome and undetectability claims. Treat those as vendor marketing, and confirm permitted resources with the employer before using live assistance.
LockedIn AI: Live and Practice Workflows
Pricing: $54.99/month or $39.99/month billed every three months.
Documented scope: LockedIn AI documents live interview answers, code solutions and coaching, plus mock interviews and post-session reports.
Trade-off: Its behavioural and technical modes cover several interview formats. The lower monthly rate requires a three-month billing commitment.
Practice Before the Call
Live copilots provide prompts during the interview when permitted. Practice tools are used beforehand, so you can test examples and answer follow-up questions without depending on an overlay.
ApplyArc: Interview Prep Without Live Answers
Role-specific preparation: generate tailored interview questions from the job description, with STAR guidance based on the experience you provide. It does not record, replay or score mock interviews.
See Best AI Interview Prep Tools in 2026 for the comparison criteria.
18 AI tools total: including cover letter writing, resume optimization, salary negotiation and follow-up emails. ApplyArc is £19/month or £45 every three months, with 5 free AI generations each month.
No live overlay is used during the interview. You still need to follow the employer's interview instructions and any workplace AI rules.

Do not infer permission from a vendor's "undetectable" or "stealth" claim. Those words describe product positioning, not the employer's rules.
CodeSignal and HackerRank illustrate why blanket claims fail: one platform restricts outside help on certified assessments, while another lets employers configure integrity features and notes that some flagged activity may be acceptable in context. The recruiter or assessment invitation remains the source of truth for a specific interview.
Legality, platform rules and employer policy are separate questions. This article does not offer legal advice.
FAQs
Is using OphyAI or any interview copilot against company policy?
Rules vary by employer, interview and assessment. Some assessment platforms restrict outside assistance or expose activity signals to reviewers. Read the invitation, ask the recruiter when needed, and do not treat a vendor's visibility claim as permission.
Can interviewers detect OphyAI?
Detection depends on the interview setup. HackerRank documents signals for repeated tab switching, copy-paste, window resizing and multiple monitors when configured. OphyAI describes its overlay as discreet, but no vendor can establish what a particular employer permits.
Which tools advertise a free entry point?
OphyAI advertises a free first Copilot session, Cluely advertises free use, and Yoodli and Sensei list free tiers. The scope and limits differ, so check each current pricing page.
How is ApplyArc different from OphyAI?
OphyAI provides real-time assistance during an interview. ApplyArc provides practice before it, plus job tracking and ATS tools. Compare the workflow you want, and check the employer's policy before using any live copilot.
