Email, by voice. Lumin is a voice-first email assistant for your iPhone. Tap once, talk to it, and it reads, replies to, deletes, and triages your email — without you having to look at a screen. Designed alongside the blind and low-vision community. Useful for anyone who'd rather work with their voice than their thumbs. What you can do • Triage your morning inbox — "What's new?" and Lumin reads through your unread mail, one by one. Say "delete," "archive," "mark as read," "reply," or "next." • Write replies by voice — Dictate naturally. Lumin writes professional, full-sentence emails that don't sound like AI. Review before you send. • Find what you need — "Find the email from my doctor last week." Lumin searches your inbox and reads back what it finds. • Get the gist of a long email — "Summarize this." Lumin reads you the key points instead of the full message. • Hands-free, eyes-free — Works while you're making coffee, walking the dog, or anywhere you don't want to stare at a screen. Built for accessibility Lumin is designed to work alongside VoiceOver — or to replace the parts of email that VoiceOver makes painful. No more swiping through subject lines. No more wrestling with HTML emails. Just talk. Privacy Your email stays yours. Lumin only reads what you ask it to read, and only writes when you tell it to. We never sell, share, or train on your inbox content. Built by Luminade Inc. in San Francisco.

About

Ramble

Features
Read full description

Ramble is for people who think best out loud. Talk to think: say it however it comes out, and Ramble turns it into something clear. Press the microphone and just talk. Your words appear as you speak. Play it back and each word lights up as you hear it. Tap any sentence to add the thought you forgot, spoken or typed, pinned to the exact spot it belongs. Press Sort. Your own words are grouped by subject, and every request is numbered, so nothing you asked for gets lost. It never rewrites you. The words stay yours. Fix a word it misheard once, and it remembers. When it reads right, press Send. Copy it, or share it straight to Notes, Mail, Messages, or a prompt for your AI assistant. Paste works too. Drop in a long reply from someone else, hear it read aloud, and tap a sentence to answer that exact part. Private by design: • Speech is turned into text on your iPhone. • Sorting runs on your iPhone. No internet needed. • No account. No sign-in. No servers. Nothing you say or paste ever leaves your phone. Works on any iPhone running iOS 26 or later.
