Show HN: Voca – Most AI tutors wander. I built one that follows a curriculum

Voca, a new AI-powered teaching platform, offers voice-first courses that build a curriculum for any skill, teach through live AI instructors with visual boards, and include mock interviews and CV building, with a pay-per-course model and no subscription. The platform, launched on Hacker News, provides a free 10-minute trial and charges once per course, with pricing based on session length and number of sessions.

Voice-first AI teaching

Start being taught.An AI teacher that builds your course — and prepares you for the interview.

Voca builds a full curriculum for any skill — marketing, business, code, whatever you need — then a live AI instructor teaches it out loud, phase by phase, with a visual board that draws along as it talks. Ask a question mid-sentence; it answers, then picks the lesson right back up. And when you are ready to put it to work, sit a live mock interview and get a written report on how you did.

Free 10-minute trial, no card needed. After that, pay once per course — no subscription, ever.

// Chapter 3 · Unit 2 of 5
// Phase: detail

Name the skill

Marketing, a programming language, public speaking — type it in. Before you pay, the full chapter list is already mapped out.

Get taught, out loud

Your instructor walks through each chapter live, phase by phase. Interrupt with a question whenever — it answers in its own words, then resumes exactly where it stopped.

Watch it build the board

Code, diagrams, and tables appear on screen the moment they matter — not as a wall of text dumped after the fact.

How a session feels

It teaches like a tutor who's actually paying attention. #

No wall of text, no whole-course info-dump. One phase at a time, checked for understanding, and genuinely interruptible — not a script that politely waits for you to finish talking.

  • intro Sets up what this phase covers and why it matters — before diving into the substance.

  • teach Walks through the real content, at the pace and style you asked for going in.

  • you jump in "Wait, back up a second" — answered on the spot, not queued for later.

  • check Actually checks you understood, instead of just asking 'does that make sense?' and moving on.

  • wrap Closes the phase cleanly and only then moves on — it never gets ahead of you.

Mock interviews

Sit a real interview, out loud. #

The second thing Voca does. Name the role and an AI interviewer runs a live round — one question at a time, under real pressure — then scores every answer in a written report.

  • Set upRole, seniority, format.
  • Sit it liveOne question at a time, out loud.
  • Get scoredA written report on every answer.

Start a mock interview

Pay once per interview — priced by the rounds and minutes you pick. No course required.

CV builder

And the CV that gets you in the room. #

The third thing Voca does. Write your CV once in six short steps, then download it in any of five designs — every one of them single-column, standard-headed, real text, so the software screening applicants reads every field instead of dropping half of them.

  • PickFive designs, previewed filled in.
  • WriteSix short steps, saved as you go.
  • DownloadA real-text PDF, not an image.

ATS-friendly by construction — not a claim bolted on afterwards.

Build your CV

One template free. The other four are a single one-time purchase — no subscription.

Pricing

One price per course. No subscription. #

No monthly fee, no tokens to ration, no surprise charges. You decide how many sessions you want and how long each runs, see the exact total before you pay, and that's charged once at checkout — a visible countdown inside the session just shows you the time you already bought. (Retaking a finished session later is a separate, much cheaper add-on — see below.)

You set the size

Slide sessions and minutes to whatever the topic actually needs. Want a crash course? Make it five short sessions. Want depth? Stretch it out.

The price, before you commit

Watch the number update live as you adjust the sliders. What you see is what you're charged — nothing changes at checkout.

Redo a session without redoing the course

Forgot what was covered in chapter 4? Re-run just that session live, for a small fraction of the course price — not the whole thing again.

Try it free first

New here? Your first session is a free 10-minute live lesson — no card, no commitment. See how it teaches before you pay for anything.

See exact pricing

Retaking a single session later is a separate, optional, much cheaper purchase.

Deutsch

Full German instruction, not a translated script — pronunciation, examples, and tone built for a German-speaking learner from the start.

English

The same depth, the same phase-by-phase teaching, fully in English.

العربية

Live instruction in natural Gulf Arabic — not a stiff, formal translation.

FAQ

The questions you'd actually ask. #

No open chat box, no "ask me anything." You name a course, we build the entire curriculum before the first session starts, and the instructor teaches it out loud in order. You can interrupt with a question — it always comes back to the lesson plan afterward, it doesn't wander.

Marketing, business skills, programming languages, anything a working professional needs to get sharper at. It's not a language-learning app and it's not school curriculum — it's built for real, applicable skills you'd otherwise pay a tutor for.

You get the full chapter list instantly, and chapter one is ready the moment you click start. Later chapters get their deep content prepared just before you reach them — so nothing is wasted building material for a chapter you never open.

Yes. Every finished session stays available for free in text-only review — the summary, every visual that was shown, and follow-up questions in text. No voice cost at all. A full live re-do, with the voice instructor again, is a separate cheap add-on.

Just speak up. The instructor stops, answers your actual question using its own knowledge, tells you it's picking back up, and continues from the exact same point — asking a question never makes it skip ahead.

Stop bookmarking tutorials. #

Get taught instead.

Name what you want to learn, answer three quick questions, and your instructor is ready in minutes — not after you finish a 40-tab research binge.

Your first 10 minutes are free — see how it teaches before you spend anything.
