Hear the page, the screenshot, or the audio on this Mac.
Paste text, read a screenshot aloud, watch a live region of the screen, listen to a page, or drop an audio file. Speech and recognition stay on your computer. No account and no subscription.
Version 1.0.0 · Deckle-1.0.0.dmg (36 MB) · Signed & notarized · Fetching a link needs the network; speech and screenshots do not.
Deckle
Deckle speaks on the Mac you already have. Paste notes, long drafts, or copied articles and press Read. Scrub across the sentence timeline at the bottom or press Control-Option-D to read highlighted text from any Mac app.
One reading surface for four kinds of input
Deckle looks like a clean note with a miniature player at the bottom. Everything resolves onto the same readable page.
Offline text to speech
Paste notes, drafts, or articles and press Read. Scrub the timeline to jump to any sentence, adjust speed from 120 to 280 WPM, or press Control-Option-D in the direct edition to read selected text from any app.
Read a screenshot aloud — or watch it live
Drop an image, paste with ⌘V, capture a screen region once, or click Read live to keep watching a region you drag and speak new words as they change on screen. On-device Vision OCR filters out photo and video noise.
Play an audio file and transcribe it here
Drop an MP3, M4A, WAV, or AIFF file to transcribe it on-device while it plays, or just play the file. In Settings, the direct edition can also tap what is already playing out of your Mac’s speakers without touching the microphone.
Listen to a page and save M4A audio
Paste a URL to extract the article and hear it locally. If a site returns a browser check, Deckle never solves or bypasses it—you finish the check yourself in a normal window you control. Save any reading as a standalone .m4a file.
What you are paying for vs. what is already free
macOS already ships with free speech tools. Use them if highlighted text is all you need.
Already free on your Mac
macOS Speak Selection, Outloud, and SpeechDock remain free for text you can already highlight in another window.
The $19 wedge
One place for pasted text, a screenshot or live region, a dropped audio file, or a link—then listen with a real sentence scrubber or save audio on this Mac. No account, sold as a one-time purchase.
Honest network boundary
Speech uses the voices installed on your Mac. Screenshots and audio are recognized on-device and are not uploaded. Fetching a link needs the network; speech and screenshots do not.
Direct DMG vs. Mac App Store edition
Deckle builds two targets so the direct edition can use power-user macOS APIs that the App Sandbox restricts.
