Say it into the machine.
CAPENATOR is the party game that checks the story. Ask the question, tap REC, let them answer. The machine writes down every word, fact-checks it live, measures the stress in the voice, and prints a reading on a paper ticket: CAP, SUS or NO CAP. If it's cap, the siren goes off and one of six voices calls it out.
THE FACT-CHECK IS REAL
What was said is checked with a live web search and two separate AI judges that score the claim from the same evidence. If they land 25 points apart it's a split decision and they're averaged. Facts get looked up. Personal claims ("I didn't eat your fries") can't be, so the judges rate how believable the answer is: plausibility, contradictions, dodging the question, over-assuring. Every ticket shows the search, the sources, and both judges' scores.
THE VOICE IS MEASURED, NOT GUESSED
On your iPhone, CAPENATOR measures the voice itself: pitch against the speaker's own register, vocal tension, cycle-by-cycle jitter and shimmer, the 8–12 Hz micro-tremor the ear can't hear, and speaking rate, compared against 1,206 real answers from 18 speakers. The stress score moves the odds using the published effect size for liars sounding tense (DePaulo et al., 2003). Voice alone never calls CAP.
THE TICKET
Chance it's true, step by step. The claim. The roast. The math. The fact-check with sources. The voice-stress gauge and the tremor spectrum. The words, with the phrases the judges pointed at underlined. Play the answer back. Sound the alarm again.
WHO CALLS IT
Six voices, five lines each: HOOD, UK, LATIN, COUNTRY, ISLAND, NEW YORK. Cycle them all or pick your favorite. The alarm plays loud even with the ring switch off, with haptics.
TWO PEOPLE ON THE RECORDING?
Upload a phone call or voice memo and the machine asks who's in the hot seat. Only that voice is scored.
THE BACK PANEL
Every weight, threshold and formula is printed on the back panel. Nothing is hidden.
PRIVACY
The microphone is on only while you hold REC. Voice stress is measured on the device. To check the words, the clip is sent to our server, transcribed and fact-checked, then discarded. No account, no ads, no tracking, nothing stored.
ONE PRICE
Buy it once. No subscription, no in-app purchases, nothing renews.
CAPENATOR is a party game for entertainment purposes. Only record people who know they're being recorded. No machine can prove a lie: the fact-check catches false facts, and the voice reading is a lean, not proof. It is not evidence and should never be used to make decisions about anyone.
