Use Cases

Every situation covered

Designed for the real moments that matter — not just quiet controlled environments.

👨‍👩‍👧Calls with family and friends

A call with parents in Tel Aviv or grandparents in Jerusalem — who speak fast Israeli Hebrew and assume you followed every word. Captio AI captions in real time so you follow the whole conversation without asking them to repeat.

💼Work calls and conference calls

A work call with colleagues in a Tel Aviv tech company where Hebrew and English mix freely mid-sentence. Put the call on speaker, point Captio AI toward the audio, and follow every product discussion and decision without missing a term.

🏥Medical and healthcare calls

A callback from Clalit, Maccabi, or Meuhedet health fund — formal Hebrew spoken quickly with medical vocabulary and appointment details. Captio AI captions every instruction in real time so nothing high-stakes is missed.

🏦Banks, utilities, and customer service

A call from Bank Leumi, Bank Hapoalim, or a government ministry — automated Hebrew menus and fast-speaking agents. Captio AI captions whatever comes through the speaker so you have the information in writing.

🌍International calls

A call from family in the United States, France, or Argentina — often mixing Hebrew with the local language naturally. Live Translator handles both languages in the same call so diaspora distance is never an additional barrier.

📹Video calls — FaceTime, WhatsApp, Zoom

A WhatsApp or FaceTime video call — the dominant channels for Israeli families across the country and diaspora. Captio AI listens through the speaker and captions in real time alongside the video feed.

Why Captio AI

Built for the calls you have been avoiding

Captions as they speak

Words appear on screen word by word while the other person is still talking. You read what they say at the same pace everyone else hears it — no delay, no reconstruction.

Works on any call app

Captio AI does not need to integrate with any platform. Put the call on speaker, point the microphone toward the audio, and read the captions. It works the same way for any app on any device.

No more asking for repeats

Every word is on screen as it is said. If you missed something, glance at the caption rather than interrupting the call — the full sentence is there.

Handles call audio accurately

Compressed phone audio is less clean than in-person speech. Captio AI is built for real-world audio conditions, including the reduced quality of standard phone and VoIP calls.

Any language

For calls with family abroad, international colleagues, or foreign-language customer service. Live Translator captions and translates in real time with no manual setup.

Record and review after

Record any call and upload it to Audio Transcription. Get a full written record of everything said — useful for medical instructions, work decisions, and anything worth having in writing.

Hebrew

Why Hebrew is hard to understand

Pharyngeal consonants

  • ח and ע are produced deep in the throat — invisible anywhere
  • Modern Hebrew has pharyngeal consonants (ח /ħ/ and historically ע /ʕ/) produced so deep in the throat that they leave no trace on the lips and create only subtle acoustic friction. These consonants appear in some of the most common Hebrew words and roots. For a hard of hearing caller, their presence is acoustically faint on compressed phone audio and has no visual backup whatsoever.

Uvular R

  • The Hebrew R is produced at the back of the mouth
  • Modern Israeli Hebrew typically uses a uvular fricative or approximant /ʁ/ — the same type of R used in French and Dutch — produced at the back of the throat with no visible lip movement. Hebrew has many minimal pairs where /r/ is the distinguishing consonant. In lip reading scenarios or when audio is degraded, the uvular R becomes acoustically faint and completely invisible.

Mizrahi-Ashkenazi phonology split

  • Older speakers distinguish sounds that younger Israelis merge
  • Israeli Hebrew blends Ashkenazi and Mizrahi phonological traditions in ways that vary by generation and community. Older Mizrahi speakers maintain distinctions between ח /ħ/ and כ /x/, and between ע /ʕ/ and א /ʔ/ — distinctions that younger Tel Aviv Hebrew speakers have largely merged. A phone call with an elderly caller sounds phonologically different from a call with a young urban Israeli — not just in accent but in the underlying consonant inventory.

Vowel-free rapid speech

  • Fast casual Hebrew drops vowels that are not written anyway
  • Hebrew is written as an abjad — an alphabet of consonants with vowels added as optional diacritics in formal texts only. In everyday speech, function words like 'של' (of), 'את' (direct object marker), and 'זה' (this) reduce almost to silence in rapid conversation. For a hard of hearing caller, the acoustic skeleton of fast Israeli phone conversation — already consonant-heavy and vowel-light — becomes a rapid blur of consonants with minimal acoustic landmarks.

Code-switching with English

  • Israeli callers insert English tech and business terms freely
  • In Israeli professional contexts, English technology, startup, and business vocabulary is embedded into Hebrew conversation as naturally as native words. A work call may shift between Hebrew syntax and English terms multiple times per sentence. For a hard of hearing person already working to follow Hebrew phonology, the unpredictable English insertion requires constant recalibration between two different phonological systems.

The Challenge

Israel's deaf community navigates daily life with limited interpretation access

According to the Israel Deaf Association and Central Bureau of Statistics, approximately 10,000 people in Israel are profoundly deaf, with an additional 150,000 to 200,000 living with significant hard of hearing conditions. Israel has a notably high rate of genetic hearing loss — GJB2 gene variants are responsible for approximately 30 percent of hereditary hearing loss in Jewish families, and more than 20 specific genes causing deafness have been identified within the Israeli Jewish hearing-impaired population. This genetic dimension means hearing loss is a prominent disability condition across all demographic groups in Israeli society, cutting across ethnic, religious, and socioeconomic lines.

Israeli Sign Language (ISL) was legally recognised in 2021, making Israel a relatively late adopter of sign language recognition despite its active deaf community. Before recognition, deaf Israelis navigated medical appointments, government services, banking, and employment without any legal entitlement to sign language interpretation support. Even after recognition, the gap between legal right and practical provision — particularly in medical settings like health fund callbacks, hospital discharge instructions, and specialist referrals — remains significant. Healthcare calls in Hebrew are high-stakes and typically have no alternative communication channel for deaf and hard of hearing patients.

Captio AI captions every Hebrew phone call in real time — so whether it is a health fund callback in Jerusalem, a work call in Tel Aviv, or a WhatsApp video call with family in New York, the words appear on screen as they are spoken.

Privacy

What you hear stays with you.

Gone the moment it ends

Captio AI processes your audio in real time and discards it immediately. Nothing is recorded. Nothing is kept.

Not a product

Your conversations are not something Captio AI sells, shares, or monetizes — to anyone, for any reason.

Not used to train anything

What you say in a doctor's appointment or a job interview never ends up in a training dataset. Not ours. Not anyone else's.

People love Captio AI

"Clalit callbacks are in fast formal Hebrew and I catch maybe half of it. With Captio AI I read the entire callback — which specialist, which date, what I need to bring. No more calling back to ask what I missed the first time."

"Tech calls in Israel are Hebrew and English mixed every other sentence — 'product roadmap', 'sprint review', then back to Hebrew. Captio AI follows both without dropping a word. I contribute to product calls properly for the first time."

"My parents speak Mizrahi Hebrew with sounds I do not always recognise — the ח and ע distinctions they still use. Captio AI captures it all. I understand calls from Jerusalem that used to be genuinely hard to follow from Tel Aviv."

"I call Israel and the family mixes Hebrew and American English constantly. I grew up English-first and my Hebrew comprehension is not perfect. Captio AI captions both languages and I follow the whole call without asking anyone to switch to English for me."
