Good app 👍👍 needs 1 feature

Good app that does what it says
Opportunity for improvement::
Some contacts have information in them that should not be shared.
InnoCaption wants to have access to all contacts.
There is no way to create a contact inside InnoCaption
Being able to create a contact, even just a name, would really make it more useful
Thanks for a good product 👍👍

Love this app

This is amazing! It works extremely well. It takes what I perceive as mumbles and perfectly transposes it. Really wonderful!

Key features include live captioning for all calls, the ability to switch between stenographer and ASR captions, text-to-speech calling with AI refinement and shortcuts, AI-powered transcript summaries, saved call transcripts, and a spam call filter. It also allows users to keep their existing phone number.

Who is eligible to use InnoCaption?

InnoCaption is available at no cost to eligible users in the United States who have hearing loss. Federal law requires users to be registered individuals with hearing loss to use internet protocol (IP) captioned telephones with captions turned on.
