About this app

Whether it's an interview or a speech, the moment you speak changes everything.

Ipteuin is a speaking coaching app that allows you to practice AI interviews along with speeches, presentations, and public speaking. Take 1:1 mock interviews with an AI interviewer and practice as if it were the real thing, covering everything from pressure interviews, English interviews, and executive interviews to interviews based on your resume. If you rehearse presentation scripts and congratulatory speeches in your own voice, the AI ​​coach will provide specific coaching.

■ Topic Speeches · Practice Presentations in Your Own Voice

Try speaking in your own voice without a script using 80 topic cards covering presentation openings, explanations, persuasion, reports and briefings, self-introductions, congratulatory speeches and toasts, and impromptu speeches. You can also directly input the topic of the presentation or speech you are preparing.

The AI ​​speech coach evaluates your core message, examples and evidence, structure and flow, and a conclusion that resonates with the audience. It provides guidance on the opening-body-closing structure, suggests a stronger opening sentence, and presents a refined speech script. It also analyzes delivery metrics such as speaking speed, pauses, and unnecessary details.

Whether it's an interview or a speech, the app provides a guide to your delivery. ■ Script Practice · Presentation Rehearsal

Paste in your script for a presentation, speech, or self-introduction and speak as if it were a real situation. You can read from the script or cover it and recite from memory.

When finished, we will identify parts you omitted or changed, and provide feedback on areas to refine using a speaking flow graph that displays your speaking speed and pauses.

■ Premium 1:1 Speech Coaching

An AI coach provides voice guidance on today's topic and mission. After you speak once, the coach listens to your speech and assigns the necessary elements—such as an opening, key message, examples, or conclusion—as the next mission, refining the same speech five times.

Once the coaching session is complete, you receive feedback for each round, the refined script, and a coaching report showing how the beginning and end have changed. You can listen to your first and last recordings side-by-side and practice answering questions from the audience.

Practice your English self-introduction and presentation with English speech coaching.

■ AI Speech Practice · Presentation Practice · Speech Practice

Prepare for presentations, practice speeches, practice reading aloud, and practice speaking all in one. Check the speed, pauses, and clear delivery—essential elements for presentations and speeches—through the Speech Coaching Report.

Select 300 excellent texts (180 for reading and 120 for pronunciation) categorized by topic and difficulty level, and read them from a single sentence to the entire text.

Your recorded voice is analyzed across six categories: original text delivery, speaking speed, pauses, consistency of speed, fluency, and volume.

It identifies phrases that sounded different, places where you hesitated in the middle of sentences, and sentences that sped up. You can immediately re-practice using a pause notation that indicates pauses with '/' and '//'.

When you read the same text again, we compare your score with your previous one to identify areas for improvement.

■ Pronunciation Practice · Breathing Practice · 7-Step Guide

We have prepared pronunciation practice to identify sounds easily confused with final consonants, breathing practice to measure exhalation length, and a 7-step speech practice guide to systematically build your skills from the end of a sentence to the delivery of the main point. ■ Premium 1:1 Interview · AI Mock Interview

An AI interviewer reads out questions aloud and follows up with the next question after listening to your answer. One of six interviewers with different demeanors and voices is randomly assigned to you.

· Interview Types: General · Personality · Job · Executive · Presentation Interview

· Pressure Interview: Sharply probes for flaws and evidence in your answers.

· Mixed English · English Interview: The interview proceeds in Korean but is suddenly asked in English, or conducted entirely in English from start to finish.

· Resume-Based Interview: Upload your resume (PDF or photo). The interviewer asks questions based on the experiences listed in the resume and asks follow-up questions to compare your answers with the resume. Your name and contact information are not saved.

· Personal Statement Editing: Write questions one by one or import an existing personal statement (PDF, photo, or paste). The system checks the intent, structure, specificity, and connection to the job. It provides a revised version tailored to the word count and sentences to be corrected, as well as predicted interview questions based on the statement. The results can be exported as a PDF. · Job Posting-Specific Interview: Paste a job posting, and it will ask questions to verify key duties and qualifications.

· Company-Specific Questions: Find the company's most recent publicly available information and insert questions linked to the job role.

· Camera Coaching Like an AI Interview (Optional): Monitor your gaze, posture, and facial expressions solely on your mobile phone, and receive coaching in the report. The video is not recorded or saved.

After answering five questions—including follow-up questions stemming from your previous response—you will receive a comprehensive interview evaluation that includes feedback on your answers, AI-recommended responses, and consistency between your answers.

■ Interview Practice by Question

Select and practice the questions you need for job interviews, ranging from self-introductions and job-specific interviews to personality interviews, English interviews, and free practice.

When you listen to the interviewer's questions and respond, it analyzes your delivery—such as speaking speed and pauses—along with points for improvement and AI-recommended answers.

It tells you the key line the interviewer will remember, how your response sounds to them, and even anticipates potential follow-up questions. In Premium, you can also view response directions for each follow-up question and condensed 30-second answers. If you answer the same question again, we acknowledge improvements compared to your previous response and tell you it is good if there is nothing to criticize.

AI personalized questions generate questions for your next practice session based on your past practice.

■ Recording and Growth

All practice is recorded, and you can listen to your recordings again for 7 days.

Check your interview score trends and changes across the six speech categories at a glance in Practice Insights.

You can manage your interview, presentation, and speech schedules with the Planner.
