Real-time filler detection
you said “um”
The instant you slip an um, uh, like, you know, so, basically, actually, or literally, the screen flashes red and the buzzer hits. On-device. Sub-second. Private.

The wedge
Three things nobody else ships.
Yoodli, Speeko, and the topic-spinner sites all stop at one half of the loop. Impromptly closes it. Real-time buzzer, one composite score, and a difficulty ladder that turns practice into a streak.
Impromptly Score 0 to 100
87
One number that combines fillers, pace, pauses, and structure. Stop guessing whether you are getting better.
Filler-Free Challenge
Buzz and ContinueBuzz and PauseStrict Fail
Pick your difficulty. The first time you finish a clean sixty seconds, you will hear it in your speech for the rest of the week.
Speaking on demand is the most economically valuable skill nobody practices.
- 01You bomb the interview because the answer never came out of your mouth before, only your head.
- 02You ramble through the pitch because you have not said the words out loud since you wrote them.
- 03You freeze in front of the room because reading your notes is not the same as running the rep.
How it works
Three steps. Sixty seconds. One score that does not lie.
- 01
Spin
Pull a prompt from 200+ curated topics across interviews, pitches, hot takes, and toasts.
- 02
Speak
Hit record. Talk for as long as the timer says. The buzzer hits the second you slip a filler word.
- 03
Score
Filler count, words per minute, and an Impromptly Score from 0 to 100. Every rep stacks.
What you get
Two features. Both designed to be the first thing you open before the room you walk into.
Spin & Speak
The night-before app for any room you have to walk into. Pick a category. Pick a timer. Spin. The casino reel lands on a topic you did not write, and you get exactly that long to make it sound like you did. After the buzzer, you get a transcript, a filler count, a pace check, and a score that tells you whether the rep was a 60 or an 89. Stop guessing whether you are getting better.
Filler-Free Challenge
Real-time filler detection that runs on your iPhone, not in some server farm in Virginia. The instant you say one of these, the screen flashes red and the buzzer hits.
umlikeyou knowuhsobasicallyactuallyliterally
Three modes: keep going, pause for a breath, or strict-fail and start over. The first time you finish a clean 60 seconds, you will hear it in your speech for the rest of the week.
What you see after every session
The score card is the product.
Every rep ends on the same screen. Transcript on top, filler words highlighted in place, three numbers that matter, and one score that tells you whether to spin again.

Is the parasocial relationship epidemic a Gen Z problem?
So basically what I think is um the parasocial thing is not new, you know, like every generation has had its version of celebrity worship, but the difference now is the algorithm just feeds it back to you constantly.

Coaching notes
- 01
You hesitated for 2.3s after the question. Practice landing your opener.
- 02
Pace climbed past 160 wpm in the last twenty seconds. Plant a beat between sentences.
- 03
Strong close. The last sentence landed on a noun, not a hedge. Keep that.
Pro adds a Claude-grade structural breakdown after each session. Topic framing, signposting, and close strength.

Questions
Things people ask before they hit record.
Audio is uploaded to a server only long enough to transcribe it, then deleted. We never store recordings. Real-time filler detection runs on-device using Apple's speech recognizer. Read the privacy policy at impromptly.ai/privacy.
On-device speech recognition catches the eight most common English filler words with sub-second latency. Whisper handles the post-session transcript at higher accuracy for the score. We do not promise perfection. We promise the count is honest enough to compete against itself.
English at launch. Adding Spanish, Portuguese, and Hindi next based on demand. Vote in-app.
Speak and ELSA teach English. Impromptly is not for learning English. It is for people who already speak English and need to speak under pressure. Different lane, different audience, different scoring.
Not yet. iOS is where the audience is. Web app is in progress for browser-based practice.
Apple handles billing for in-app purchases. Refund requests go through reportaproblem.apple.com within 90 days. We do not gatekeep refunds. If the app did not work for you, get your money back.
Settings inside the app has a "Reset all local data" option that wipes sessions, transcripts, and history immediately. If you signed in with Apple and want full account deletion, email hello@impromptly.ai and we will purge within 7 days.
Yes. Several of our pre-launch testers are non-native speakers prepping for interviews and business meetings in English. The scoring rubric is the same. The drill is the same. The buzzer does not care where you grew up.
