What each offer really pays

Day 1. You apply.

Your story.

Your resume, in your words, past the filters.

A builder that rewrites with you, an ATS score against the real job, a tailored version for every application, and the cover letter and thank-you to go with it.

Build it by chatting.

Say what changed. The whole resume is rewritten and the PDF updates beside the chat.

Six days out. You rehearse out loud.

Practise.

An interviewer that follows up and pushes back.

Say your answers out loud. The voice interviewer builds the next question from what you just said, scores you on five skills, and plays back what a strong answer would have sounded like. Ten kinds of round, as many times as you like.

Interviewer, follow-upYou said the outbox retries. What happens if the same write lands twice?

How would you make a 10,000-item feed scroll smoothly?

What: Virtualise: render only the rows on screen
Under the hood: Fixed row height, offset maths, recycled DOM nodes
Use it for: Feeds and tables past about 1,000 rows
Gotcha: Memoise rows, or every scroll re-renders them
Verify: Profiler and Performance panel show no long tasks

From the question to the outline.

What PrepAI does between the interviewer finishing a question and you starting your answer.

Hears the callIt listens to the call's sound from Zoom, Teams, Meet or any app. Your microphone stays off unless you hold the mic button.
Writes it downSpeech becomes text on your computer, or through a cloud engine if you choose one. It understands 25 languages.
Knows when the question is finishedIt waits for a real pause, notices when someone asks and keeps talking, and puts a question back together when it arrives in pieces.
Reads the questionIt works out what kind of question this is and what is being tested, before a single word of the outline.
Writes the outlineYour own AI key writes a few words per line, in the shape that fits. If one provider runs out of credit, another key you added takes over.
Coaches the roundIn a coding round it follows the ten steps of a strong answer and shows the one you haven't covered.
Reviews it with youWhen the call ends: scores, the step check, the full transcript and a thank-you email to send.

Interviewers grade the path as much as the code. In a coding round, PrepAI follows the conversation and shows the one step you haven't covered yet.

Your keys and your stories stay on your computer.

Your mic is push-to-talk

PrepAI hears the call. Your microphone listens only while you hold the button, unless you choose to record your side.

Speech becomes text on your computer

On-device speech recognition or Whisper running locally, on Mac and Windows. Cloud engines only if you pick them.

You bring the AI

A key from Claude, OpenAI, Gemini or Groq, kept in the macOS KeychainWindows' own credential store. Requests go straight to that provider.

Sessions are yours

Sessions, stories and resumes are saved on your computer. Questions join the shared bank, without names, only if you leave that on.

Pay for the days you need it.

Every plan is a one-time pass for a day, a week or a month. Nothing renews.

Prices in Indian rupees. Every plan is a one-time pass; nothing renews. AI usage is billed by your provider to your own key.

Questions before you download.

Does it work on Mac and Windows?

Yes. PrepAI runs on macOS 26.5 or later and on Windows. Early access opens on Mac first and Windows follows; the same link gets you both. On either, it listens to calls in any app that plays sound through your computer.

Do I need my own AI key?

Yes. Add a key from Claude, OpenAI, Gemini or Groq in Settings. You pay the provider directly, usually a few cents per question depending on the model.

What happens to my audio?

Audio is turned into text as it arrives and is not saved. The text of each question goes to the AI provider you chose so it can write the outline.

Which languages does it understand?

25 interview languages, including Hindi, Tamil, Telugu, Kannada, Malayalam, Marathi and Bengali.

Does my plan renew?

No. A plan is a pass for one day, one week or one month.

Can I use it in any interview?

Check the rules for your interview first. Some companies welcome notes and tools during the call and some do not. Preparation, mock interviews and practice are fine everywhere.

Be ready when the question lands.

Leave your email and we'll send one link when your build is ready, Mac or Windows. Nothing else.
