InboxToAudio vs NaturalReaders

Both turn writing into speech. NaturalReaders reads the document in front of you. InboxToAudio turns the newsletters, reports, and PDFs already in your inbox into a private listening queue, with chapters, a synced transcript, and audio that is still there tomorrow.

Available on web, iPhone, Android, and Chrome. Capture a tab, forward email, photograph a page, or share an article, then listen with lock-screen controls and MP3 download.

Where InboxToAudio pulls ahead

If NaturalReaders feels like a reader for the file you have open, InboxToAudio is built for the backlog that keeps arriving.

A private inbox, not a paste box

Forward from Gmail, Outlook, or Apple Mail, subscribe a newsletter once, or capture a page with the optional Chrome extension. No mailbox password and nothing left open in a tab.

A queue that waits for the commute

Each item becomes an episode with chapters, a synced transcript, saved position, and MP3 download. Re-listening never spends minutes.

Cleaned before it is spoken

Unsubscribe footers, view-in-browser lines, and tracking come out first. You hear the writing, not the email chrome.

Which should you choose?

Choose InboxToAudio if…

  • Unread newsletters, board packs, and long threads already land in email, and you want them waiting as audio.
  • You listen across sittings, during your commute, dishes, or gym time, and need chapters, a synced transcript, and a saved position.
  • You do not want to hand over a mailbox password and want the browser extension to remain optional.
  • You want one queue on web, iPhone, and Android, with MP3 download when you need a file.

NaturalReaders may fit if…

  • You need to highlight a paragraph on any webpage or Google Doc and hear it immediately, in the tab you already have open.
  • You want to clone your own voice or steer delivery with a reading-style prompt.
  • You are studying a document and want recap, quiz, and chat tools on the same file.

Extension versus inbox

The NaturalReaders Chrome extension reads text live in the current tab. The InboxToAudio Chrome extension captures that page and adds it to a private queue, alongside email and files, so it is still waiting after you close the tab.

Hear your own inbox first.

Set up a private listening address in under two minutes. Forward one newsletter, report, or PDF and press play.
