Comparison
The Room IQ vs practicing with ChatGPT voice
You can practice a difficult conversation with ChatGPT's voice mode, and for casual practice it works. The difference is what each tool is built for. ChatGPT voice is a general assistant that you turn into a sparring partner with your own prompt. The Room IQ is built only for rehearsal: personas prepared for the scenario, three pressure levels, and a scored report at the end.

The short version
| ChatGPT voice | The Room IQ | |
|---|---|---|
| Built for | Anything you ask | Rehearsing high-stakes conversations |
| Setup | You write the role-play prompt | Say what is coming, pick a scenario, or paste your context |
| The other side | Plays the role you describe, and tends to stay helpful | A persona with a position, prepared for the case |
| Pressure | Depends on your prompt, and can soften as the chat goes on | Cordial, Skeptical, or Hostile, held for the whole session |
| Presentations | You can ask it to listen | Uninterrupted opening, then a panel questions what you said |
| Feedback | A general impression, if you ask | Five competencies scored 1 to 5, with evidence from what you said |
| Progress over time | Lives in your chat history | Scores and history across sessions |
| Pricing | Free tier or a monthly subscription | One-time minute packs, no subscription |
Where ChatGPT voice is the better choice
It would be dishonest to pretend a general assistant is never enough. Use ChatGPT voice when:
- You already pay for it and want a quick, informal run-through
- You are still working out what to say, and want to brainstorm arguments and wording
- The situation is unusual and you are happy to write a detailed prompt to set it up
- You want to practice speaking in another language in general
Where a dedicated rehearsal room is different
General assistants are tuned to be helpful and agreeable. That is what you want from an assistant, and it is the opposite of what you want from someone playing your skeptical CFO. Without careful prompting, the role-play tends to give ground, summarize your argument for you, or step out of character to encourage you.
In The Room IQ the counterpart has one job: to be the other side of your conversation. It holds its position at the pressure level you chose, asks follow-up questions about what you actually said, and does not coach you in the middle of the conversation. Coaching has its own place: the Mentor mode before the rehearsal, and the report after it.
The report is the second difference. Asking a chatbot "how did I do?" gets you an opinion. The Room IQ scores five competencies from 1 to 5 against a rubric, points to the moments that earned each score, and tells you what to work on in the next attempt. The scores build into a history, so you can see whether you are getting better.
A fair way to decide
Try the same conversation in both. Give ChatGPT voice a careful prompt and rehearse your salary conversation or your board question. Then run it in the Open Room: about a minute to say what is coming, then a five-minute conversation and a report. Keep whichever one made you change what you were going to say.
Questions people ask
Can I practice a difficult conversation with ChatGPT?
Yes. With voice mode and a good role-play prompt, ChatGPT can play the other person. You are responsible for the setup, for keeping it in character, and for asking for feedback at the end.
Is The Room IQ built on a general AI model?
It uses real-time voice AI models under the hood, like any product in this category. What it adds is everything around the model: written cases and personas, pressure levels, the presentation and panel format, the scoring rubric, and the report.
Which one is cheaper?
It depends on how you use them. ChatGPT has a free tier and monthly plans that cover many other uses. The Room IQ has no subscription: you buy minute packs once and they never expire, which suits people who rehearse before specific conversations rather than every day.
Can I use both?
Yes, and they work well together: a general assistant to draft and think, and a rehearsal room to find out how the words hold up when someone pushes back.
