Spar with a partner who pushes back.

+SP is a sparring partner for interviews, exams and high-stakes conversations. It asks, listens, cuts in when you stall and presses on what you missed. Then it grades both what you said and how you said it.

Free during early access. Nothing to download: open it in your phone’s browser and talk.

Coach cuts in after 5 s of silence

How a round works

Think out loud. Get stopped. Get better.

Every round follows the rhythm of a real interview or meeting, then turns into coaching.

  1. You get a real situation

    A station, a case, a ward call or a client meeting, picked from your plan for today.

  2. You answer out loud

    Talk or type. No buttons to hold: it listens and sends when you stop.

  3. Stall, and it cuts in

    Five seconds of silence and your partner nudges you, the way a real panel would.

  4. It presses on the gap

    One sharp follow-up on the most important thing you missed.

  5. You get a two-part verdict

    Content against a rubric, plus delivery: answer first, signposting, filler, a clear next step.

  6. Ask anything, then go again

    No question is too basic. Then the next situation, with weak skills coming back on schedule.

Fields

Expert where it says it is.

The first screen asks for your field. Fields with ready-made coaches are marked, and the list is honest: if your field isn’t on it, +SP isn’t expert in it yet.

Medicine & health

Ready-made

Medical school, residency and MMI interviews: ethics, confidentiality, candour, prioritising on call. Clinical communication: SBAR handover, history taking, ABCDE, breaking bad news, consent, an angry relative.

Consulting, finance & PE

Ready-made

Case interviews, case maths, market sizing, unit economics, DCF and LBO, deal triage and red flags, with case files to work from.

Interviews in any field

Ready-made

Competency questions with STAR: deadlines, conflict, failure, leadership, “tell me about yourself”, “why us”.

Investor pitches

Ready-made

The 60-second pitch, the numbers behind it, and the hard questions investors actually ask.

Why +SP

Practice that feels like the real room.

Realistic partners

It talks back

An interview panel, an attending, a patient, a hiring manager, an MBB partner, a CFO, a VC, a journalist. Each one probes the way that person would, under time pressure.

Delivery, not only content

Graded on how you said it

Did you lead with the answer? Signpost? Fill silence with “um”? End with a next step? Do the maths out loud? Every check explains itself, and you get a tighter version of your own answer.

Learning by working

Situations, not flashcards

Each situation trains several skills at once and says which. A daily plan counts down to your date, and every skill keeps coming back until it sticks.

Your English

Plain or realistic talk

Clear textbook English, or fast native speech with real jargon (“query sepsis”, “what’s the so-what”), explained after the round. US, UK, Canadian, Australian and Indian accents.

Private by design

Identifying details never leave your phone.

Before anything you say is shown, graded, stored or sent, +SP masks names and places on your device (Austin becomes S****t, whether it was a person or a city) and removes contact details, ID numbers and exact dates. Diagnoses, doses and figures stay, so the coaching still works.

  • No ads, no trackers, no selling data. No cookie banner, because there is nothing to track.
  • No account needed. With one, your progress follows you across devices; your answers stay on your device unless you choose to back them up.
  • Download or delete everything from the app, at any time.

On medical, legal, financial and engineering topics, coaching carries a short note: for training, not advice. Real decisions belong with qualified professionals.

What you said

“I’m worried about Mr John Smith, 72, from Austin, day 2 after hip surgery. Heart rate 118, BP 92/60. His daughter is on 555-123-4567.”

What leaves your phone

“I’m worried about Mr H**j T***m, 72, from S****t, day 2 after hip surgery. Heart rate 118, BP 92/60. His daughter is on [phone].”

Questions

Before you spar.

Is this medical, legal or financial advice?

No. +SP trains how you reason and communicate. Patients and cases are fictional, and decisions about real patients, clients or money belong with qualified professionals and official guidance.

Do I need to install anything?

No. It runs in your phone’s browser. On Android, Chrome can also install it as an app (menu → Install app), and voice works there too. On iPhone, use it in Safari: Apple doesn’t give Home Screen web apps speech recognition yet, so voice works in Safari only.

Which fields is it good at?

Ready-made coaches cover medicine and health interviews and clinical communication, consulting, finance and PE, investor pitches, and competency interviews in any field. For the other listed fields, +SP builds a coach from your goal and syllabus. A field that isn’t listed is one we aren’t expert in yet.

What happens to what I say?

Names and places are masked, and contact details, ID numbers and exact dates are removed, on your device first. What remains goes to our AI provider, Anthropic, to produce feedback; it isn’t used to train their models. Your browser turns your voice into text; we never receive audio.

What does it cost?

Early access is free for invited testers. Paid plans will come later, with prices shown before you choose anything.

Which AI is behind it?

Anthropic’s Claude models, held to a quality floor: only the most capable models grade your answers. Built-in practice material has been reviewed for accuracy.
