About

Voxnotes

Features
Read full description

Read anything aloud. Private by design. Voxnotes turns your notes, articles, and documents into natural-sounding audio — powered by neural AI voices that run entirely on your iPhone. No servers. No account. Every voice runs on your device; every note lives in your Apple account, never ours. Your notes deserve to be heard. ▸ WHY THIS APP EXISTS Most text-to-speech apps send your words to remote servers. Your private notes, journal entries, work documents — all processed on someone else's machines to generate audio. Voxnotes works differently. Every voice runs on a neural engine built into the app itself. Everything happens on your iPhone. There is no server. There is nothing to intercept. Your notes are yours. ▸ REDISCOVER YOUR ARCHIVE The best note is the one you wrote six months ago and forgot about. Hit shuffle on years of notes. Listen on the drive, the run, the walk. Old thinking comes back in new contexts — research from a past project, a half-finished idea, a quote you captured and can't remember why. Your past-self has more to say than you think. ▸ LISTEN TO ANYTHING Share content from any app on your iPhone: • Notes from Apple Notes, Craft, Notion, Obsidian — anything with a Share button • PDFs, Word docs, PowerPoint, Excel, Pages, Keynote • Web articles and saved pages • E-books (EPUB) • Emails and images (on-device text recognition) Or paste text directly. It just works. ▸ VOICES Premium AI voices that run entirely on your iPhone. Warm, expressive, calm. Not robotic. Not theatrical. Voices that get out of the way so the words can land. Eight languages. Multiple voice styles. No celebrity gimmicks. Try a premium voice and the built-in system voice on the same note. Hear the difference yourself. The free tier includes Apple's best built-in voices in 30+ languages — no subscription needed. ▸ PLAYBACK • Lock screen controls — play, pause, skip without unlocking • AirPods and Bluetooth — seamless • Speed control — 0.5x to 2.0x • Shuffle your whole archive — rediscover old notes on random • Queue and resume — pick up where you left off • Works fully offline — listen anywhere, no signal needed ▸ SIRI & SHORTCUTS "Hey Siri, read this with Voxnotes." Built-in Shortcuts actions for hands-free control. ▸ PRICING Free: Apple's best built-in voices, unlimited notes, full playback. Premium: AI voices that sound human, all supported languages. Monthly, annual, or a one-time lifetime purchase. No trials that silently auto-renew. No hidden limits. No surprises. You see the price. You decide. ▸ PRIVACY • No tracking — verified in Apple's App Privacy report • No account or sign-up • No servers — every voice runs on your device • iCloud sync is optional — when on, your notes sync through your own Apple account, end-to-end encrypted. We never see them. • No internet needed for playback • Crash reports only, opt-in, anonymous We didn't bolt privacy onto a cloud app. We have no servers to bolt anything onto. ▸ FORMATS Plain text, RTF, PDF, EPUB, DOCX, PPTX, XLSX, Pages, Keynote, HTML, CSV, ODT, EML, web archives, images (OCR), web URLs. ▸ LANGUAGES Premium AI voices: English, Japanese, Chinese (Mandarin), Spanish, French, Hindi, Italian, Portuguese. Built-in voices: 30+ languages including German, Korean, Arabic, Russian, Dutch, Swedish, Polish, Turkish, and more. Automatic language detection — the right voice for your text. ▸ ABOUT Built by one person. No venture capital. No pressure to sell your data. No celebrity voices. Just a focused app that does one thing well: reads your notes aloud, privately.
