Features

Built for real conversations

Words that match what was said

Captio AI captures what someone actually said, not a rough paraphrase. So you can trust the transcript when it matters — at the doctor, in an interview, in a meeting.

Zero latency

Latency is well under a second. Captions appear word by word while the person is still speaking, so you read what they say at the same moment everyone else hears it.

Know who is talking

In groups and meetings, Captio AI labels each speaker separately so you always know who said what, without watching faces or tracking lip movements.

60+ languages

Follow a conversation in French, Japanese, or Arabic the same way you follow one in English. No switching modes. Hearing loss is never also a language barrier.

Handles languages that mix mid-sentence

When people switch languages mid-conversation, Captio AI keeps up. No gap in the captions, no mode to switch.

Teach it your vocabulary

Add names, medical terms, or specialist words you hear often. Captio AI uses your vocabulary list to caption your actual conversations more accurately.

Add a language hint

Tell Captio AI which language to expect and it starts tuned in from the first word — useful when the spoken language is not obvious from context.

Retranscribe later for more accuracy

Run any recording through again after the fact for a cleaner transcript. Useful for lectures, appointments, and any conversation worth reviewing.

Read it your way

Adjust text size, background color, and contrast until captions are easy to read at a glance — phone in hand, flat on a table, or propped on a desk.

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.
