Why rehearse

The moments that shape careers are the ones you can't practice.

Coaches cost $200+ per session. Books don't build muscle memory. AI chat answers questions but doesn't simulate pressure. Hopper does.

Real stakes

Real stakes, rehearsed

Interviews, raise conversations, PIPs, first 1:1s as a new manager — the conversations where one wrong answer costs you the job, the role, or the team.

Memory

Stakeholders with memory

AI characters have persistent personalities, agendas, and memory across the conversation. They push back. They remember what you said five minutes ago.

Feedback

Feedback that compounds

Every session scores you on content, structure, delivery, and role-specific skills — with quoted coaching. Watch your growth across sessions.

The library

Every career-defining moment, ready to rehearse.

Pick an archetype tuned to your role and industry, or generate a custom scenario from your resume and target company.

Interview simulation

Multi-round, branching, tuned to the role and company you're targeting. Paste a JD and interview with an AI hiring manager who adapts to your answers.

VoiceBranching20–45 min

Difficult conversations

The first-time manager giving hard feedback

Practice delivering difficult feedback to a low performer. Your direct report has explanations, emotions, and pushback. You have to stay calm, specific, and clear.

Voice1 stakeholder15–25 min

Salary negotiation

Negotiating the offer you've been waiting for

Counter a lowball. Handle a multi-offer scenario. Push for equity you haven't been offered. The recruiter on the other end has a target and a ceiling.

VoiceMulti-round10–20 min

First 90 days

Your first stakeholder meeting as the new hire

The room has an agenda of its own. You're the new leader expected to add value — without stepping on the toes of people who've been here for years.

VoiceStakeholder persona15–25 min

First-time manager

The 1:1 where a conflict on your team surfaces

A star performer is complaining about a peer. You've been a manager for three weeks. There's no playbook for this moment — until now.

VoiceDirect report15–20 min

Don't see yours? Generate a custom scenario from your resume, target company, and focus area — in under 20 seconds.

How it works

Three clicks to talking.

From “I need to prepare for this” to practicing it out loud — in under two minutes.

Pick your scenario

Browse archetypes by role and industry, or paste a job description to generate a custom simulation. Both land you in the same place: ready to practice.

Talk it through

Voice-first. You talk to an AI stakeholder — interviewer, manager, direct report — who adapts to what you say, pushes back, and remembers what you told them.

See exactly how you did

A dedicated feedback page with per-dimension scores, quoted coaching, full transcript, and the next simulation Hopper thinks you should run.

Feedback

Feedback is a destination, not a notification.

After every session you land on a full feedback page — not a pop-up, not an email. Four dimensions, quoted coaching tied to what you actually said, and a tracker that shows you getting better over time.

FAQ

Questions people ask before their first run.

Is this text chat or real voice?+

Voice from day one. You talk, the AI stakeholder talks back in real time. Text fallback is available if you'd rather type — but we built Hopper because muscle memory requires hearing yourself out loud.

How realistic is the AI interviewer / manager / report?+

Each stakeholder has a persistent persona — personality, agenda, communication style — and memory across the session. They push back. They follow up. They connect what you said five minutes ago to something you said now.

What happens to my resume and transcripts?+

Resumes are encrypted at rest and tied to your account. Transcripts are retained so you can review and watch your progression. Audio is not stored — it's streamed, transcribed, and discarded. Delete your account and everything goes with it.

Can I practice for a specific company?+

Yes. Paste a job description or use on-demand generation with your target company. For marquee companies (Amazon, Meta, Google, Stripe, and 20+ others) we have curated scenario rubrics. For everyone else, Claude generates a scenario grounded in public signals about the role and company.

What if I'm preparing for something that's not on the list?+

Every paid tier includes custom scenario generation. Tell us the moment you need to rehearse — "denying a raise to a tenured employee who's threatening to leave" — and Hopper builds the scenario, the stakeholder, and the rubric in under 20 seconds.

Is there a team or company plan?+

Not at launch. Hopper is self-serve for individuals in v1. Team, outplacement, and HR-department plans are on the roadmap for later this year — if that's you, drop your email and we'll reach out when it's ready.
