Comparison, updated August 2026
Big Talk vs ChatGPT
ChatGPT is excellent at writing an interview answer, generating follow-ups, and roleplaying a hiring manager in text. It cannot hear your pace, fillers, or pauses. Big Talk is the speaking gym you use after the draft exists. The useful recommendation is both, in that order, not one instead of the other.
Big Talk publishes this comparison. We focus on differences a buyer can verify.
| Dimension | Big Talkthis site | ChatGPT |
|---|---|---|
| What it actually scores | Your spoken take: pace, fillers, pauses, clarity, hedges, relevance to the prompt. | The text you typed or pasted. It does not hear the delivery unless you upload audio. |
| Privacy | On-device. No account. Nothing uploaded to Big Talk. | Chats go to OpenAI. Do not paste confidential compensation stories or unreleased decks into a chat you would not email to a vendor. |
| Interview prep | Say the STAR answer out loud. See whether you stayed on the question. | Draft the STAR answer, ask for holes, generate likely follow-ups. |
| Presentations and pitches | Rehearse the actual minutes, with a WPM chart and pause quality. | Rewrite the outline, tighten slides copy, suggest a closer. |
| Fillers | Live filler counter on the voice you are producing. | Can remind you to avoid fillers in text. Cannot count the ones you say. |
| Price | Free 14-day window on iPhone, then 3 analyses / 30 days or Lifetime. | Free ChatGPT tier plus paid plans. Separate from any speaking app. |
The deciding line
Choose Big Talk
You need to hear the answer, not just read it. You want filler, pace, and pause data from your voice. The rehearsal should stay on the iPhone. You already have the content and the problem is delivery.
Choose ChatGPT
You are still figuring out what to say. You want a list of likely interview questions for a role. You want a rewritten paragraph, not a spoken score. You are not on iPhone.
A workflow that actually holds up
1. Ask ChatGPT for the questions, the holes in your story, and a tighter outline.
2. Put the words you want to say into Big Talk as a script or just start talking.
3. Record about a minute. Read the score, the filler highlights, and the one next step.
4. Repeat the same prompt until Then-vs-Now sounds like someone you would hire.
ChatGPT should not be the place you “practice speaking.” It is the place you practice thinking. The room hears the second skill.
Why ChatGPT cannot replace a speaking gym
Spoken pace is not visible in a chat transcript. Neither is a three-second stall, a cluster of likes, or a smile you can hear. Those are the things that change whether an answer lands.
If you upload audio to a chatbot so it can “grade your speech,” you have turned a writing tool into a cloud speech coach, with the privacy profile that implies. Big Talk exists so that step can happen on the phone instead.
