Speed reading for PDFs, EPUBs and web articles
Read faster, without losing context.
SwiftBrief guides you through a document one word at a time while the original page stays in view. Import a PDF, an EPUB or a web article, set your pace, and pick up exactly where you left off. Everything stays on your device.

There is no sync between devices: each one keeps its own library.
How it works
One word at a time. The page never leaves.
Most speed readers strip the document away and flash words at you. SwiftBrief keeps the source visible, so a chart, a heading or a footnote is always a glance away.

Interactive demo
Try SwiftBrief's reader
Everything above works. Tap the word to play or pause, use the round buttons to skip and change speed, then try the reader settings here.
Guided, not forced
Words appear one at a time at a fixed point, so your eyes stop scanning and start reading. Tap to pause, skip back or forward twenty words, or change speed mid-flow without losing your place.
Word or line highlighting
The page stays above the word and follows along. Highlight just the word being shown, or the whole line it sits on, so a glance up always lands in the right place.
Adaptive pacing
The demo uses the app's own timing rules. Long or technical words get a little longer, common words a little less, and sentences end with a breath. Switch between Minimal, Moderate and Strong to feel the difference.
Features
Everything a focused reader needs. Nothing it doesn't.
A library that keeps its place
Filter by Recent, Favourites, Unread, Webpages, EPUBs or PDFs. Search by title, rename items, and see progress and time remaining at a glance.
Navigate long PDFs
Jump by chapter from the table of contents where the PDF provides one, or scrub through page thumbnails and resume reading from any page.
Tune the reader to you
Set your words per minute, font size, accent colour, handedness, dark mode, highlight behaviour and whether reading auto-starts.
Summaries, on device
On supported Apple devices, SwiftBrief can generate a document summary with Apple Intelligence and open it straight back in the reader. Nothing leaves your device.
Optional. Requires a device that supports Apple Intelligence.
See your momentum
The Stats tab tracks time saved, your personal best speed, completion rate, words read over the last seven days, and reading milestones.
Bigger screens
Room for the page and the words.
On iPad the page sits above the reader at full width, with the document name, page count and progress alongside the controls. The same app runs on Mac with Apple silicon.
Privacy
Your reading is your business.
SwiftBrief is local-first. There is no account to create and no server on the other end.
Documents stay on your device
Imported PDFs, EPUBs and articles, your reading position, settings and stats are stored on the device you are using. They are not uploaded anywhere.
No sign-in, ever
Open the app and start reading. No email address, no password, no tracking profile.
Summaries are generated on device
When available, summaries use Apple Intelligence running on your own device rather than a cloud service.

Apple Watch · coming soon
Summaries on your wrist.
A companion Apple Watch app is on its way. Summaries and quizzes you create on iPhone will appear on the watch on their own, and you can read a summary one word at a time with the Digital Crown setting the pace. Your position carries back to the phone. It travels straight between the two devices with no account and no cloud, and it reads summaries rather than whole documents.
