The interview coach
that listens to
how you sound
Twenty minutes of real conversation about the actual job you're going for, then a report on how you came across: your pace, your energy, where the steadiness went. It remembers, so session two starts where session one finished.
Your free session is a full 20-minute coaching call, not a taster.
From a real PrepCall session
The story was good.
It just didn’t sound like it.
A candidate told a story about delegation. PrepCall looked at that one answer twice: once at what was said, and once at how it sounded.
The detail is there. The story has structure, the specifics are present, and the reasoning holds up.
Any tool that reads a transcript can tell you this.
Your delivery carries less forward momentum than the content deserves, and outcome sentences in particular tend to trail rather than land.
Only a tool that listened can tell you this.
Both halves are from the same PrepCall report. In the real interview they arrive together, and the delivery is what carries the content. Good material can still land softly.

your words. We

Every session is analysed across dozens of vocal qualities: pace, energy, steadiness, variation, how much you fill the silence. It's an analysis of how you sound, not a reading of how you feel.
Your voice can go flat on a day you feel completely fine, and that still matters, because the person across the table only gets the sound. The way you tell a story is what an interviewer remembers. It's also the part you can't practise alone in front of a mirror, because you can't hear yourself while you're doing it.
Try a free 20-minute sessionDozens of vocal signals
Pace, energy, steadiness, variation, hesitation, the shape of your pauses. Measured across the whole twenty minutes and per question, so you can see which answer took it out of you.
Hears what you stop noticing
After the fiftieth time you tell a story, you can't hear yourself any more. We can: where the pace runs away, where the energy drops, where the steadiness goes.
No camera. Just your voice.
Nothing to perform for, no lighting, no worrying about where to look. You focus on what you're saying. We handle the rest.
How it works,
honestly
Three steps. No simulation, no guessing your interviewer's questions, no pretending we can do either.
Upload & analyse
Drop in a job spec, tell us the company, and upload your CV. We extract the key requirements and build a preparation plan around you, the role, and the company.
Talk it through
Twenty minutes of real conversation with a coach that has read the job description and your CV. It pushes back on vague answers and asks the follow-up, and it isn't pretending to be your interviewer; it's on your side.
Hear yourself back
A written report: what you said, how you sounded saying it, which answer landed and which one drifted, and the two things to fix before the real thing, rather than a score out of ten.
Built for any role with a job description: healthcare, engineering, education, product, law, marketing, the public sector, and yours.
Only you ever
hear this.
PrepCall analyses your voice. You should know exactly what that means, so here it is in plain terms.
What we analyse
How you sound: pace, energy, steadiness, variation and similar vocal qualities, measured while you speak. That's a measurement of delivery. It isn't a measurement of what you feel, and it isn't a psychological assessment.
What we don't keep
The recording. Your voice is analysed as you speak and the audio is never stored, not by us and not by the service that does the analysis. We keep the written transcript and the measurements of how you sounded so we can write your report and show you your progress. Deleting your account wipes the lot, permanently, and you can do that yourself from the account menu at any time.
Who never sees it
Employers. Recruiters. Hiring platforms. Anybody making a decision about you. PrepCall is sold to one person, the one practising, and we won't sell it to organisations to assess candidates or staff. That isn't our current policy. It's the product.
A lot of people applying for jobs right now have been assessed by an AI without being told it was happening. We built the opposite of that.
Why
PrepCall?
The questions candidates ask most, answered.
The questions don’t matter.
Your answers do.
We won’t pretend to predict the exact questions you’ll face. No tool can. The interviewer in the room has their own list, their own follow-ups, their own tangents.
What we can do is something more useful: get you fluent in your own story before you walk in.
Articulation reps
Saying something out loud is different from thinking it. The first time you tell a story, it’s clumsy. By the fifth, it’s tight. Practice moves answers from your head into your mouth.
Sharpened stories
Most candidates know which projects to talk about. Few know how to land them in 90 seconds with a clear arc. Our coach pushes on structure, specifics, and impact, so the stories actually work.
Composure under pressure
The hardest part of interviewing isn’t the question, it’s answering it while a real person watches. We rebuild that pressure so the real room feels familiar, not foreign.
The candidates who perform best in real interviews aren’t the ones who guessed the questions right. They’re the ones who already knew what they wanted to say.
ChatGPT hears your words. PrepCall hears your voice.
We analyse pace, energy, steadiness and hesitation. A chat tool has no idea how you sounded, because it never heard you.
Built for coaching, not conversation.
PrepCall’s AI coaches are trained in established interview frameworks (STAR, CAR, SOAR) and know how to push you on weak answers, not just respond to them.
Session two picks up where session one left off.
We re-test your weakest area, then advance to new ground. ChatGPT forgets the moment you close the tab.
It won’t tell you that was great.
A general assistant is built to be agreeable. A coach isn’t. If an answer was vague, you’ll be told it was vague, and then asked again.
You walk away with a coaching report, not a chat log.
Structured feedback mapped to the job description, using frameworks real coaches use, ready to review the night before your interview.
Can't I just use
ChatGPT?
You can. But here's what it can't do.
Invest in yourself
Interview skills are career skills. The confidence you build here stays with you long after you land the role.
Build muscle memory
The more you practise, the more natural your answers become. Great interviews aren't improvised, they're rehearsed.
Find your voice
Learn to talk about your experience with clarity and confidence. Know your story and tell it well.
Practice with real feedback
Every session gives you specific, actionable feedback. Not just a score, but exactly what to improve and how.
Fine-tune your delivery
It's not just what you say, it's how you say it. Refine your messaging until it feels authentic and compelling.
