Three reading modes — RSVP, Scrub, and Reader — with instant switching and a single synced position. Finish more books without sacrificing understanding.
Toggle between RSVP and Reader mode. Your position stays perfectly synced — just like in the app.
One word at a time, at your speed. No eye movement. ORP alignment locks focus on each word's recognition point. Adaptive timing handles punctuation and complexity automatically.
Drag to scrub through words with momentum physics. A sliding context window keeps you oriented without breaking focus. The fastest way to rewind and catch what you missed.
Full page text with your position highlighted. Scan ahead, re-read, let your eyes roam. One tap snaps back to RSVP — right where you left off. Your instincts, your pace.
Most readers treat PDFs like flat images. Velo's on-device intelligence pipeline transforms raw PDFs into structured, navigable reading experiences.
Automatically detects chapters, parts, and sections from the PDF's structure. Hierarchical table of contents with word counts and progress tracking per chapter.
Footnotes are extracted from the page layout and linked inline. Endnotes are matched to their references. Back-matter sections like bibliography, index, and appendices are detected and separated.
Running headers stripped. Page numbers removed. OCR artifacts cleaned up. Two-column academic layouts properly resequenced. What you read is the author's words — nothing else.
Works with scanned books too. Vision OCR extracts text from photographed pages, then the same intelligence pipeline structures it into chapters and clean prose.
On-device processing. Your books never leave your device.
Every feature solves a real reading problem. No gimmicks.
RSVP gets you through books 2-3x faster. The reading list that's been haunting you? You can actually finish it this year.
Confused by a passage? Switch to Reader mode. Re-read, scan back, get your bearings — then return to speed without losing your place.
RSVP eliminates eye wandering and distractions. One word, one moment, full attention. Especially effective for ADHD readers.
Your library is fully offline. No connection needed. Cloud sync picks up when you reconnect, so you're always at the right page on every device.
"Reading is not one activity. It's a dynamic process where the reader constantly adjusts strategy based on content difficulty."
— The principle behind Velo's three-mode design

Yes — when you pair RSVP with the right tool. RSVP eliminates subvocalization and eye wandering, which are the two biggest bottlenecks for comprehension speed. When a passage gets dense, switch to Reader mode with one tap, re-read at your natural pace, then jump back to RSVP without losing your place. The modes are a toolset, not a race.
Classic speed reading gimmicks (skimming patterns, "photo reading") don't survive scientific scrutiny. RSVP is different — it's a display technique used in reading research labs for decades. It doesn't magically make you read faster; it removes physical barriers so you can read at your true thinking speed. Most people find their sweet spot between 400 and 700 WPM.
EPUB and PDF. Import from Files, Safari, Mail, or any app via the iOS Share Sheet. Velo includes on-device processing for chapter detection, footnote extraction, and text cleanup. Scanned PDFs work too — Vision OCR extracts the text, then the intelligence pipeline structures it into clean prose.
Velo's AI pipeline for complex academic and scanned PDFs. It extracts the real structure — chapters, headings, footnotes, endnotes, back-matter — into a clean, navigable reading experience. Pro includes 25 Enhanced Processing conversions per month. You can buy more any time with 10-credit ($4.99) or 50-credit ($19.99) packs. Credits never expire.
Yes. Your entire library is stored on your device. You can read, switch modes, and track progress without any network connection. Cloud sync picks up automatically when you reconnect.
Your Pro subscription covers iOS, iPadOS, and — soon — macOS. Cloud sync keeps your library, reading position, highlights, and notes in sync across all of them automatically. Start a chapter on iPhone at the gym, finish it on iPad at home.
Many ADHD readers find RSVP especially effective because it eliminates the eye-wandering and visual distractions that break focus in traditional reading. Dyslexic readers often benefit from the controlled word presentation and the ability to adjust speed, font, and spacing to their preference. Velo isn't a medical treatment, but the focus-first design helps.
Your subscription is managed by Apple. Cancel any time in iOS Settings → Apple ID → Subscriptions. No phone calls, no forms, no "are you sure?" popups designed to make you give up.
Your books never leave your device for basic reading. On-device processing handles EPUBs, text files, and simple PDFs. The only time content touches a server is during Enhanced Processing (opt-in, for complex PDFs) or cloud sync (encrypted in transit and at rest). We don't sell data, run ads, or track what you read.
Those apps are great for linear reading. They don't have RSVP, don't have mode switching, don't run locally on your own PDFs without re-uploading, and don't process academic or scanned books into structured content. Velo is for people who read across formats and want a faster way to finish the stack.
Velo is entering public beta on TestFlight. Join the waitlist and we'll send your install link the moment Apple approves the build.
