Use Cases

Every situation covered

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

📺Live TV — news, sport, events

HRT and Nova TV run live news that pre-generated captions lag behind. Point Captio AI at your TV and read the Croatian as it is spoken, not several seconds behind the anchor.

🎬Streaming content

HRTi and other platforms vary in subtitle quality and availability. Captio AI works as a consistent fallback for any Croatian show or film that ships with wrong, delayed, or missing captions.

📱YouTube and social media

YouTube auto-captions for Croatian are often inaccurate and most social video has none. Point Captio AI at your phone and read accurate Croatian captions for any clip.

🌍Foreign-language content

A foreign film, a foreign documentary, a non-Croatian channel. Live Translator captions and translates in real time so anything becomes watchable in Croatian as it plays.

🎭Cinema

Not every cinema showing is captioned. Hold Captio AI near the audio and read real-time Croatian captions of the dialogue discreetly from your seat.

🎧Podcasts and audio content

Most Croatian podcasts have no transcript. Hold Captio AI near the audio or upload a recording, and read the whole episode in writing.

Why Captio AI

Built for the content that subtitles fail

Captions any content in real time

Point the phone toward any speaker — TV, laptop, tablet, cinema screen. Captio AI captions whatever is playing, regardless of whether that platform provides subtitles.

Faster than built-in subtitles for live content

Pre-generated subtitles lag behind live TV by several seconds. Captio AI captions in real time — so you read what is being said as it is being said.

Works on any screen or device

No integration required. Point the phone toward the audio source — the same approach works for a large TV, a laptop screen, a cinema, or a phone held at arm's length.

Any language, translated in real time

For foreign-language content, switch to Live Translator. It translates as content plays — so a French film, a German documentary, or a Japanese series all become watchable.

No subtitle file needed

Captio AI captions from the audio directly. No subtitle file, no platform support, no creator requirement. If audio plays, Captio AI can caption it.

More accurate than auto-generated captions

The industry average for AI-generated subtitles is a 10–15% word error rate — roughly 1 in 10 words wrong (3Play Media). Captio AI is built for accuracy in real-world audio conditions.

Croatian

Why Croatian is hard to understand

Pitch accent

  • Rising and falling tones the screen cannot show
  • Standard Croatian has a pitch-accent system with rising and falling tones and distinctive vowel length on stressed syllables. These separate words but ride entirely on pitch and duration, with no lip cue. On a drama or a news read a deaf viewer sees identical mouths for words the accent keeps apart.

Ijekavian reflexes

  • The 'ije' and 'je' sequences that reshape words
  • Standard Croatian is Ijekavian, where the old jat vowel surfaces as ije or je — reshaping common words into longer diphthongal sequences. On screen a deaf viewer finds familiar terms carry unfamiliar vowel shapes.

Three dialect groups

  • Shtokavian, Kajkavian, and Chakavian differ sharply
  • Croatian spans three dialect groups — Shtokavian, Kajkavian, and Chakavian — that differ so much they can challenge mutual understanding. A show with a Zagreb speaker and a Dalmatian character presents a deaf viewer with different phonologies to track.

Affricates and clusters

  • č and ć, dž and đ, plus dense clusters
  • Croatian contrasts the affricate pairs č/ć and dž/đ, which look nearly identical on the lips, and permits demanding consonant clusters. On screen these fine distinctions and compressed clusters leave a deaf viewer with little visual footing.

Croatian–English code-switching

  • English dropped into Croatian content
  • Croatian TV, film, and online content drop English terms into Croatian sentences. A deaf viewer meets English phonology on the key word, then returns to Croatian, with no visual warning and no lip to read after a cut.

The Challenge

In Croatia, only the public broadcaster captions the news

In the 2011 census Croatia recorded over 13,000 people with impaired hearing, and the country's association of the deaf and hard of hearing has around 9,000 members, against a European backdrop in which about one in five people has some hearing loss. The public broadcaster HRT offers subtitles for deaf viewers on part of its output — marked with a T on the schedule and available via Teletext page 888 — and carries Croatian Sign Language on some programmes.

But coverage is narrow. According to the Croatian Deaf Association, only HRT subtitles the news; other broadcasters largely do not. Deaf-specific subtitling is concentrated on informative programmes, live content can lag, and commercial, streaming, and social content vary widely. The pitch accents and close affricates that make Croatian hard to lip-read leave a deaf viewer stranded wherever a caption is missing.

Captio AI does not depend on the broadcaster or the platform. Point the phone at any screen — a live Nova TV bulletin, a Croatian drama, a YouTube clip — and read Croatian captions in real time from the audio, whether or not that content was ever captioned.

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.
