hCalls Chrome extension logo
Available on Chrome Web Store

Chrome · Edge · Brave

Run hCalls from your interview tab. Keep the guidance on your phone.

The hCalls extension captures live meeting audio from Google Meet, Zoom, and Microsoft Teams, pairs with your phone by QR code, and streams concise response outlines and coaching - so you stay organized without keeping a dashboard on the shared screen.

hCallsLIVE

AI interview copilot for your browser

Dual-track audio

Captures meeting-tab audio and your microphone separately for clearer transcripts.

Concise coaching on your phone

QR-pair once, then get response outlines and talking points - not a wall of text - off your shared desktop.

Session-based capture

Audio does not begin automatically. Capture starts only when you explicitly start a session.

Open the extension, select a session, scan the QR code, then start capture. Audio never begins automatically - stop anytime from the extension or phone.

Your Brain Knows the Answer.
Your Mouth Betrays You.

The best AI interview assistant doesn't just prep you - it provides structured guidance in real time. Especially useful if you get nervous, interview in a second language, or are changing careers.

Your Mind Goes Blank at the Worst Moment

Speech speeds up. Fillers take over. You forget the project that would have been perfect. Under pressure, your brain closes exactly when you need it open.

ChatGPT Doesn't Know You

Generic AI gives you textbook answers that don't mention your projects, stack, or impact. Interviewers can smell generic. You need answers from your own resume.

You Know the Story. You Can't Structure It Live.

Behavioral answers need a spine. Without real-time structure guidance, you ramble, lose the point, or forget the result. STAR answers get callbacks. Rambling doesn't.

You Forget Your Own Wins Under Pressure

You scaled that system to 10M requests. You cut deploy time by 40%. But when they ask 'tell me about a performance optimization' - your mind goes to Google, not your actual achievement.

AI Screeners Score You on Rubrics You Can't See

HireVue, Karat, and Byteboard score you on criteria you never see - speech clarity, problem decomposition, technical depth. A great answer in the wrong structure fails anyway.

Set Up in 3 Minutes.
Run in 4 Different Ways.

Upload your resume, paste the JD, then pick your mode - Web, Phone, Browser Extension, or Desktop. Same AI engine underneath, whichever way you run it.

Interviews in 2026 Come in Two Flavors.
We Handle Both.

AI screening bots don't ask follow-ups. Human interviewers don't follow scripts. Your tool needs to handle both realities.

AI Screener Round

The Bot Has Already Decided Your Score Before You Finish Speaking

AI-assisted screening and automated interview formats are becoming increasingly common in early-stage hiring across modern tech and enterprise teams. Large-scale field studies demonstrate AI evaluating communication, problem decomposition, and structure against automated rubrics before human rounds. A great answer in the wrong structure fails.

How hCalls Helps
  • Captures AI bot audio questions in real-time
  • Generates rubric-aware bullet points in 2 seconds
  • Formats responses for scoring algorithm patterns
  • Works with pre-recorded and live bot question formats
Human Interview Round

Your Interviewer Is Watching Your Eyes. Not Your Screen.

The classic format - a human on camera, sometimes with screen share, sometimes with live coding. You need to sound natural, structured, and confident. Nervousness is visible. Silence costs you.

How hCalls Helps
  • Listens silently alongside your call - no mic interference
  • Matches questions to your resume automatically
  • Streams STAR-structured talking points to your screen or phone
  • Engineered to keep coaching off your shared screen

One AI Engine. Four Ways to Run It. Built for Every Interview Setup.

From "I Froze Up"
to "I Got the Offer"

Real results from candidates who used hCalls to walk into their interview with the right answer, every time.

Vikram S.
Vikram S.Staff Software Engineer at a Ride-Sharing Giant
System Design Panel

I failed four consecutive Staff loops because I'd freeze during the high-scale system design panels. The volume of concurrent questions always got to me. I used hCalls for my next round-the Copilot captured the prompts and cleanly mapped out a Redis sharding architecture on my screen. I stayed structured, kept my cool, and landed the offer.

Sarah K.
Sarah K.Backend Developer at a Fintech Scaleup
Technical Coding Loop

I went through three failed loops where I couldn't explain my code complexity under pressure. I started doubting my skills. I set up hCalls the night before my Stripe interview. When the interviewer threw a recursive graph problem, the Copilot instantly laid out the space-time tradeoffs. I explained it perfectly and got the offer.

Marcus L.
Marcus L.Full-Stack Developer at a Web3 Tech Startup
AI Screener Interview

AI screener bots were my absolute nemesis-I failed five in a row because my natural speaking style didn't hit the scoring algorithm. I tried hCalls for a Web3 startup's screen. The Copilot structured the answers to the rubric format live. Passed the screen and got the recruiter call the next morning.

Elena V.
Elena V.Engineering Manager at a HealthTech Unicorn
Behavioral & Leadership Loop

I failed three EM loops in a row because I struggled to structure behavioral scenarios under pressure. My stories felt disorganized. hCalls changed everything-the Copilot recognized the prompts and mapped my career achievements to the STAR framework live on screen. It was the first time I felt 100% in control.

Everything You Want to Ask
Before You Buy

Setup, privacy, speed, and platform questions - answered directly.

Can interviewers tell if you are using AI?

They can if you pause unnaturally, look away from the camera, or read generic scripts. hCalls is built to keep coaching off the shared display: phone companion streams talking points to a second device, and the Windows overlay uses OS display affinity so supported screen-sharing tools do not capture it. That is not a guarantee against every recorder, proctor, or platform. Always check your share preview and follow the interview rules.

Can you use AI for interview questions?

Yes for preparation: structure stories, rehearse STAR answers, and map your resume to the job. Live assistance is only appropriate when the employer and platform allow it. If the rules prohibit external tools, use hCalls for practice instead.

Which AI is best for interview questions?

It depends on the job. A general chatbot is strong for brainstorming before the call. A live interview assistant is built for the moment a question is asked: capture audio, use your resume and job description, and stream talking points without you stopping to prompt. hCalls is designed for that live workflow across Zoom, Google Meet, and Microsoft Teams.

What happens if I share my screen during an interview?

Pick a mode that keeps guidance off the shared surface. Phone companion sends answers to your phone. The Chrome extension captures Meet, Zoom, or Teams tab audio while coaching stays on the paired phone. The Windows app uses display affinity so the overlay is excluded from supported screen shares. Always verify the share preview. No setup is guaranteed against every recording or proctoring tool.

Is my interview data, resume, and audio private and secure?

Audio is streamed during an active session for transcription and guidance. It is not retained as a permanent meeting recording. Session details and account settings follow the hCalls Privacy Policy. You are responsible for interview rules, platform policies, and any participant-consent requirements. Review https://hcalls.com/privacy for full details.

How fast does hCalls respond during a live call?

hCalls captures and structures guidance in real time. Latency from speech detection to the first talking point is under 2 seconds, so suggestions arrive as you would naturally pause to think.

Does it generate generic AI answers or references to my actual experience?

Guidance is mapped to your uploaded resume and the job description you provide. Talking points should reflect your real projects, skills, and metrics. Do not read the model word-for-word, and do not claim experience you do not have.

What kinds of interview platforms and formats does it support?

hCalls supports Zoom, Google Meet, and Microsoft Teams through web, Chrome extension, phone companion, and desktop workflows. Some AI screening assessments can be practiced or supported when the format and rules allow it. Compatibility depends on the exact setup. Follow the assessment instructions.

What answer styles are available during the interview?

You can switch between STAR (Situation, Task, Action, Result), Quick Answer (2-3 talking points), and Bullet Point cues. Guidance is a concise outline, not a wall of text.

Can I use hCalls in any interview?

No. Interview rules differ by employer and platform. If AI or external assistance is prohibited, use hCalls beforehand for preparation and mock practice. You are responsible for complying with those rules.

Does hCalls guarantee I'll get the job?

No. AI guidance can be incomplete or wrong. You remain responsible for reviewing suggestions, communicating honestly, and following interviewer rules. hCalls does not guarantee interview performance, job offers, or transcription accuracy.
