Designed for the real moments that matter — not just quiet controlled environments.
Most Portuguese conversations happen fast, at normal pace, without warning. Captio AI captions every word as it's spoken, so you can follow without asking anyone to repeat themselves.
🤟Communicating with Deaf & HoHHearing people often don't know how to adapt when talking with deaf or hard of hearing Portuguese speakers. Captio AI turns their speech into real-time captions, so the conversation can happen naturally on both sides.
💼MeetingsIn Portuguese meetings, decisions happen fast and people talk over each other. Captio AI captions every speaker as they talk, so you never miss a decision or a question directed at you.
🎓LecturesPortuguese lecturers speak quickly, cover complex material, and rarely repeat themselves. Captio AI gives you a live transcript of everything said, so you can follow the content instead of straining to hear it.
🏥Doctor AppointmentsDoctors speak quickly in Portuguese and use clinical language that's easy to mishear. Captio AI shows you everything they say in real time, so you can follow your diagnosis and ask the right questions.
🤝Job InterviewsMissing a question in a Portuguese interview means answering wrong or asking for a repeat. Captio AI shows you every word the interviewer says, so you can focus entirely on your answer.
📱Phone & Video CallsPortuguese phone and video calls are harder to follow than in-person conversations. No lip reading, often poor audio quality. Captio AI captions whoever is speaking in real time, so you do not need to ask for repeats.
👥Group SettingsIn Portuguese group conversations, multiple people talk at once and the thread moves fast. Captio AI keeps up with whoever is speaking, so you can follow without losing where the conversation is going.
🍽️Restaurants & CafesBackground noise in Portuguese-speaking restaurants and cafes makes speech hard to follow. Captio AI focuses on whoever is speaking to you, so you can have a real conversation through the noise.
✈️TravelingIn Portuguese-speaking cities, airports, and hotels there is no margin for mishearing. Captio AI captions speech in real time, so you can navigate confidently wherever you go.
🎤Conferences & EventsAt Portuguese conferences, speakers are far away, acoustics are unpredictable, and you cannot ask for a repeat. Captio AI gives you a live transcript of every speaker, so you can follow the full event from any seat.
📺TV & MediaBuilt-in subtitles on Portuguese TV, films, and videos are often wrong, delayed, or missing. Captio AI captions whatever is playing in real time, so you are not dependent on what the content provides.

Supports Brazilian Portuguese, European Portuguese, and African Portuguese varieties.
European Portuguese dialect
Spoken in mainland Portugal — faster speech, reduced vowels, and distinct phonology from Brazilian Portuguese. Captio AI handles both Lisbon standard and Northern Portuguese varieties accurately.
Brazilian Portuguese dialect
The most spoken Portuguese variety with ~215 million speakers. More open vowels, different stress patterns, and simplified verb conjugation compared to European Portuguese. Fully supported.
Carioca dialect
The Portuguese of Rio de Janeiro — distinctive 'sh' sound for 's' before consonants and a musical intonation. One of the most recognisable Brazilian regional varieties. Captio AI handles Carioca Portuguese accurately.
Nordestino dialect
Spoken across northeastern Brazil — Bahia, Pernambuco, Ceará. Features open vowels, a distinct rhythm, and some archaic vocabulary. Captio AI handles the Nordestino accent accurately.
African Portuguese dialect
Spoken in Mozambique, Angola, Cape Verde, and São Tomé. Closer to European Portuguese in grammar, with distinct accents influenced by local Bantu and Creole languages. Captio AI handles African Portuguese varieties with good accuracy.
Captio AI supports 60+ languages

Gone the moment it ends
Captio AI processes your Portuguese 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 Portuguese doctor's appointment or job interview never ends up in a training dataset. Not ours. Not anyone else's.
Hearing accessibility for Portuguese speakers
Portugal and Brazil each have their own sign language. Portugal uses Língua Gestual Portuguesa (LGP), recognized in 1997, with around 60,000 users. Brazil uses Língua Brasileira de Sinais (Libras), legally recognized in 2002. They are separate, distinct languages and are not mutually intelligible. A deaf person from Lisbon and a deaf person from São Paulo do not share a sign language.
Brazil's scale makes the situation particularly significant. It has one of the largest deaf communities in the world. Research suggests only around 15% of deaf Brazilians are fluent in written Portuguese. For many, Libras is their primary language and access to written information in the dominant spoken language is limited. This affects everyday tasks: reading official documents, understanding medical instructions, navigating public services.
Hospital consultations in both Portugal and Brazil are conducted in spoken language with no captioning or interpretation unless arranged in advance. In Brazil, access to Libras interpreters exists in major cities but thins out significantly in rural areas and across the Northeast. For hard of hearing people who do not sign, formal support is rarely available at all. Captio AI works across both Portuguese-speaking contexts.
