About

Zenvor

Turn your reading backlog into your own private radio. Share an article, paste text, or import a PDF — Zenvor starts speaking in a natural AI voice within seconds, generated entirely on your device. No account. No cloud. Free core listening, forever. Scan paper with the camera — a single page or an entire book — or open a scanned PDF, and Zenvor recognizes the text on your device and reads it aloud. Scanning is free, with no page limits, and nothing leaves your device. WHY ZENVOR IS DIFFERENT Mainstream reading apps synthesize speech on servers, so they meter your hours, require accounts, and charge accordingly. Zenvor's neural voices run on your iPhone's own chips: - Unlimited listening — no hourly caps, no word credits - Works fully offline, even in airplane mode — after a one-time online setup on first launch - No analytics, no ads, no tracking — the App Privacy label reads "Data Not Collected" - Nothing to sign up for, nothing to cancel LISTEN TO ANYTHING - Articles and web pages you choose to fetch - Newsletters and RSS feeds - PDF and EPUB documents - Pasted notes, drafts, and study material BUILT FOR REAL LISTENING - Natural neural voices in English, Spanish, French, Italian, Portuguese, Hindi, Chinese, and Japanese - More than 50 neural voices ship inside the app — American and British casts, male and female, warm to newsreader-plain - Word-by-word read-along highlighting - A gapless queue that plays your backlog like a podcast - A sleep timer that stops after a set time, at the end of the item, or at the end of the chapter - 0.5×–4× speed with per-item speed memory - Background audio with full lock screen and AirPods controls - Bookmarks, clips, and listening history - Export a listening item as an audio file to save or share — the voiceover is rendered on your device (unlimited with Zenvor Pro) - Siri and Shortcuts: "Play my queue in Zenvor" LEARN WHILE YOU LISTEN - Chinese read-along with pinyin and tap-to-define glosses - On-device AI summaries — hear the key points first (Zenvor Pro, on devices with Apple Intelligence) - Define or simplify any word without leaving the reader (Zenvor Pro, on devices with Apple Intelligence) PRIVACY, BY ARCHITECTURE The network is used only when you explicitly ask Zenvor to fetch a link or feed. Speech, summaries, stats, and history are created and stored on your device — never uploaded, never analyzed, never sold. ZENVOR PRO (optional) Core listening is free forever, and every language above includes a free native voice. Pro unlocks the full voice cast, unlimited offline downloads, full listening-stats history, deeper synthesis look-ahead, and the on-device AI tools: key-point summaries, Ask about this, Define and Simplify. Pro is also sold as a one-time purchase — buy it once, keep it, no subscription required. Clear prices, no forced trial, cancel anytime. Made for iPhone, iPad, and Apple Silicon Macs by an independent developer in Los Angeles.
