Screen-aware reading for serious work
Scroll is a Mac app that explains what is on your screen, follows your reading pace, highlights key lines, and lets you ask questions about the page you are already viewing.
This is what it does. Scroll to hear it.
This is what Scroll does. As your eyes move down a page, a voice keeps pace — summarizing when you fling, explaining when you settle, and going quiet the instant you move on. Stale narration is worse than silence, so it never falls behind.
Scroll is not a generic text-to-speech app. It is built for the moments where the document is already open and you need to stay oriented: morning research scans, contract review, paper study sessions, and screen-aware follow-up questions.
When Scroll is narrating, it can briefly mark important keywords, phrases, and lines on the current page. The highlight layer is built from visible text and coordinates after scrolling settles, so the spoken explanation stays attached to the page.
Scroll again and the generated highlights clear immediately. The next settled view gets a fresh snapshot, fresh timing, and the right amount of depth for your pace.
Contracts, analyst notes, research papers, dashboards, and long articles. Scroll stays on the page with you instead of pulling the work into another chatbot window.
Long contracts, filings, and regulations. Scroll reads them in the mode you need: Look for the risks, Ask for a spoken follow-up, or Read Aloud when you need the clause itself.
Read contracts aloud →Earnings reports, analyst notes, dashboards. It narrates the numbers and, with visual context enabled, the charts, so you absorb a 40-page deck while you're doing something else.
Listen to reports →Papers, textbooks, lecture notes. Set it to Deep and it walks you through the argument. Stop scrolling and it goes deeper on whatever's on screen.
Study by listening →Skim a dozen articles in the time it takes to read one. Scroll fast and it gives you the gist; slow down and it fills in the detail.
Listen to articles →Abstracts at a glance, the method when you slow down, the exact line when you ask. Scroll reads PDFs, arXiv, and journal pages and explains the argument as you skim.
Listen to papers →Mail, Notes, Pages, PDFs, Safari, Chrome — anything Vision OCR can see. If it's on your Mac, Scroll can read it aloud and tell you what matters.
Read documents aloud →Choose the interaction that matches the job: explain while you skim, talk to the screen, or read the core text aloud.
Toggle Scroll on and keep reading normally. It watches your scroll pace, explains what you skim, highlights what it mentions, and uses low-cost speech by default.
Toggle a live voice conversation about the current screen. Ask stays open across turns and answers when you stop speaking; toggle it off to end the conversation.
Toggle a smart reader. Scroll uses the low-cost text step to choose the relevant body content, skips surrounding UI chrome, then speaks that selected text with TTS.
In Look, fast scrolls get the gist, slow reading gets a walkthrough, and stopping gives the deepest explanation your settings allow.
Highlight any passage and it explains just that, everywhere.
The speech menu follows the selected mode: Look and Read Aloud use low-cost speech; Ask offers realtime Standard or Economy. Local-only mode is still available when you want nothing to leave the Mac.
Flip one switch and nothing leaves your Mac — Apple's models for comprehension, system speech for the voice.
Cloud narration uses your own OpenAI API key — you pay OpenAI directly. Local-only mode needs no key.

No. Scroll is a one-time $49 purchase with a lifetime license for up to three Macs and updates included. Cloud narration uses your own OpenAI API key, billed by OpenAI directly. A fully local-only mode needs no key and no subscription of any kind.
Scroll requires macOS 26 Tahoe or later. It relies on recent system frameworks for on-device text extraction, Vision OCR, and local speech, so earlier macOS versions are not supported. It runs on any Mac that can install macOS 26 Tahoe.
You do, directly to OpenAI, with your own API key. Scroll never sees your key, your usage, or your bill — the key lives in your macOS Keychain and calls go straight from your Mac to OpenAI. Prefer no cloud usage? Local-only mode uses Apple's on-device models and the system voice.
Yes. Turn on local-only mode and nothing leaves your Mac: Apple's on-device models handle comprehension and the system voice handles speech. No OpenAI key is needed for local-only mode. Cloud mode is optional and only runs when you explicitly enable it.
Scroll reads Safari, Chrome, Electron apps, Mail, Notes, Pages, and PDFs — plus anything Vision OCR can see on screen. It extracts the text locally, so if the content is visible on your Mac, Scroll can read it aloud or explain it in place.
Text is extracted on-device, and screen images are sent only when you enable visual context. You can keep an exclusion list of apps Scroll refuses to read, like banks or password managers, and emails, card numbers, and secrets are redacted before any text leaves your Mac.
Yes — a 7-day free trial with every feature unlocked. It asks for your email only, with no credit card. After the trial, Scroll is a one-time $49 purchase with a lifetime license for up to three of your Macs.
