Hey love — what time are we meeting today?
Around six? The table is booked under Ada.
I’ll be the one in the orange coat.

Phone calls should be simple, not stressful. With Linea you see every word as it’s said, so you can follow along and answer in your own way.

Answer by voice or by keyboard
Speak back like any call, or type and let Linea read your words aloud in a voice you choose.

Call. Read. Reply.
Dial anyone. Their words appear as they speak, and you answer out loud or by typing — whatever feels easier today.
Questions, answered plainly.
Still wondering about something? Ask a person — we reply within a day.
Who can use Linea for free?
Anyone whose hearing loss makes phone calls hard. You confirm it once in the app; captioning is paid for by a public accessibility fund, so there is nothing to buy and no subscription.
Does it work with my current number?
Yes. Keep your mobile number for calls and texts, or take a free new number just for captioned calls. The people you call won’t notice a difference.
How accurate are the captions?
Linea pairs speech recognition tuned for phone audio with corrections as each sentence completes, so names, numbers and addresses come through reliably. Flag any line to help it learn.
Can it caption people in the same room?
Yes. Room mode uses your phone’s microphone to caption the people around you and labels each voice, so you always know who said what.
Are my calls and transcripts private?
Transcripts are stored on your phone, not on our servers. Audio is processed only for the length of the call and is never used for advertising.
Which languages does it support?
More than forty, including Spanish, French, Mandarin, Arabic and Hindi. Linea notices when a speaker switches language and follows along.
Do I need an internet connection?
Calls need mobile data or Wi-Fi, like any app-based call. Saved transcripts stay readable offline.
Will it work with my hearing aids?
Linea pairs with Bluetooth hearing aids, cochlear implant processors and headsets, so you can listen and read at the same time.
Your next call can be the easy one.
Free for people with hearing loss. Ready in five minutes on the phone you already own.
