vui
Read anything aloud, on-device
Only for iPhone
Free · Designed for iPhone
iPhone
Paste text, share a page from Safari, or open an EPUB or PDF, and vui reads it aloud in a natural voice, highlighting every word as it goes.
vui reads to you in a natural voice, and talks back.
Paste text, share an article or a selection from Safari, or open an EPUB or PDF, and vui reads it aloud. The sentence being read turns colour and each word is highlighted as it's spoken, so you can follow along or put the phone down and listen. Tap any word to jump there. Your place is saved in every document, and the library shows what you're in the middle of.
The voice is generated on your iPhone, not streamed from a server. vui's speech model is built by Fluxions for long-form reading: numbers, times, prices and abbreviations are spoken the way a person would say them.

CHAT
Type or talk to an assistant that runs on your iPhone. It can remember things you tell it, keep notes, do sums, search the web for news, weather and answers, and, if you turn it on, read and add calendar events. Start a live call to talk back and forth hands-free, with replies spoken in the same voice. The assistant works best on iPhone 15 Pro and newer; iPhones with less memory run a smaller model.
ON YOUR DEVICE
Speech and the chat model run on your iPhone. Your documents, notes and memories are stored on your iPhone, not on our servers. Web searches and pages you ask for are fetched from the internet. Anonymous usage stats and crash reports can be turned off in Settings. An account is optional: it's needed to send feedback and for web search. Signed out, the assistant looks things up on Wikipedia.
The first time you use it, vui downloads its voice (about 700 MB) and, for word highlighting, a small timing model (about 190 MB). The assistant downloads its own model the first time you open Chat. Downloads use Wi-Fi unless you allow cellular in Settings.
Replies from the assistant are AI-generated and may be inaccurate or objectionable.
