NEW Live voice practice, out loud — not another chatbot

Rehearse the
conversation before it counts.

Talk out loud with an AI that plays the interviewer, the skeptical buyer, or the stranger at the party — then get delivery feedback that's actually measured from your voice and video, not guessed from a transcript.

Why people practice here

Real reps, not another chat window.

Most "AI practice" is typing back and forth with a bot. Yellowmind is a spoken rehearsal room — you talk, it talks back in character, and every session ends with feedback you can trust.

Talk to it out loud — and it talks back.

Pick a scenario and start speaking. A voice-driven AI persona responds in real time, stays in character, and pushes back like a real interviewer, buyer or colleague would. You can even interrupt it mid-sentence — just like a real conversation.

  • Sub-second, natural back-and-forth over your mic
  • Personas that get tougher as you turn up the difficulty
  • Barge-in supported — cut in, recover, keep going

Feedback you can actually trust.

Every session ends with a scorecard — but here's the difference: we tell you exactly which numbers are measured from your real audio and video, and which are an AI's opinion. No black box, no vibes dressed up as data.

  • 📏 Fillers, pace, pauses, pitch & energy — measured, not estimated
  • 👁 Eye contact, posture & expression — read from your camera
  • 🤖 Clarity & relevance — clearly labeled as AI judgment

Practice literally anything.

Choose a ready-made scenario or describe your own in a sentence — "a final-round PM interview with a skeptical hiring manager" — and we build the scene, the character and their pushback for you. Interviewing? Drop in the job description and your resume, and the questions come tailored to the role.

  • Upload a job description + resume for role-specific mock interviews
  • Set the character, their demeanor and how hard they push
  • Choose live conversation or recorded Q&A

The difference

Measured, not guessed.

Most AI coaches read a transcript and hand you a confident-sounding score. But a transcript can't hear your monotone, your rushed pace, or your nervous "ums" — and it definitely can't see whether you looked up. We measure your delivery from the actual signal, and we're honest about the rest.

📏 Measured

Facts from your audio & video

Computed from the real recording — timings, waveform, pitch and on-device vision. Not an opinion.
  • Filler words — every "um", "like", "you know", counted
  • Words per minute & pace consistency
  • Pauses & hesitations, longest silence
  • Pitch, energy & monotone detection
  • Eye contact & gaze aversion
  • Posture, smile & expressiveness
🤖 AI estimate

Judgment, clearly labeled

Genuinely useful, but it's an AI's read — so we badge it as one instead of dressing it up as data.
  • Clarity of your answer
  • Relevance to the question
  • Perceived confidence
  • Competency & structure scores
  • Strengths & "work on next time"
  • Coaching tips for your next rep
Real practice, not a shortcut

Get genuinely good —
not good at hiding an AI.

The other "AI interview" tools feed you answers through an earpiece and promise you're undetectable. That help vanishes the second you close the laptop — and it can get you caught. Yellowmind has no stealth mode, by design. You do the talking; we just make sure you're ready for the real room.

Rehearse it here. Nail it there.

How it works

From nervous to ready in three steps.

1

Pick your scene

Choose a ready-made scenario or describe your own. Interviewing? Add the job description and resume so it's tailored to the exact role you're chasing.

2

Have the conversation

Speak out loud with the AI persona in real time — or record your answers to set questions. It pushes back, follows up, and keeps the pressure realistic.

3

Get honest feedback

See what you actually did — measured delivery metrics, an AI read on content, what worked and what to fix — then run it again and watch the trend climb.

FAQ

Good questions.

Is this just another AI chatbot?

+

No. Yellowmind is built for talking out loud. You speak, an AI persona replies in a real voice in real time, and it stays in character — interviewer, buyer, defensive colleague, or anyone you invent. The point is to rehearse the actual spoken conversation, nerves and all, not to trade typed messages with a bot.

What does "measured, not guessed" actually mean?

+

Things like your filler words, speaking pace, pauses, pitch and energy are computed directly from your audio, and your eye contact, posture and expressions are read from your camera. Those are facts, and we badge them 📏 measured. Softer judgments — how clear or relevant your answer was — come from an AI, so we badge them 🤖 AI estimate. You always know which is which.

Is my video and audio private?

+

Yes — privacy is built in. The camera analysis (eye contact, posture, expression) runs entirely in your browser, so your video never leaves your device; only the numeric summary is saved. Recordings are automatically deleted after 7 days, while your scores and transcript stay so you can track progress.

Can I practice for a specific job interview?

+

Absolutely — that's a core use case. Paste or upload the job description and your resume, and Yellowmind grounds the questions and the interviewer's persona in that exact role. Pick an interviewer style too, from friendly to a rapid-fire stress interview or a senior-exec panel.

What can I practice besides interviews?

+

Sales pitches and objection handling, difficult conversations and feedback, presentations and Q&A, networking and small talk, or any scene you describe yourself. If it's a high-stakes spoken moment, you can rehearse it here first.

Do I need any special setup?

+

Just a browser, a mic, and a camera if you want the visual feedback. There's nothing to install. A quick one-time camera calibration keeps the eye-contact and posture readings accurate for your setup.
