Read a book in 2 hours.

Blip is a desktop RSVP (Rapid Serial Visual Presentation) reader built for personal use to dramatically speed up reading while keeping focus high. It streams one word at a time with tuned timing, trail words, and ORP highlighting so you can skim less and comprehend more.

• Download: Get the latest installers from the Tagged builds page: blip tags.
• macOS (DMG):
  • Download the .dmg from the latest tag and drag Blip RSVP Reader.app to Applications.
  • If Gatekeeper says the app is damaged, remove quarantine and open:

    xattr -dr com.apple.quarantine "/Applications/Blip RSVP Reader.app"
    open "/Applications/Blip RSVP Reader.app"

• Windows (EXE):
  • Download the .exe from the latest tag and run the installer.
  • If SmartScreen warns, choose More info → Run anyway.

macOS: Simply delete the old app from Applications and install the new version. Your app data (settings, file library, etc.) will be preserved as it's stored separately in ~/Library/Application Support/com.blip.rsvp-reader/.

Windows: Uninstall the old version and install the new one. Your data is stored in %APPDATA%\com.blip.rsvp-reader\ and will be preserved.

• Emphasized Optimal Recognition Point (ORP) highlighting
• Adjustable delays: word, character, and punctuation
• Trail words and letter spacing controls
• Local file library with large-file streaming
• Global shortcuts for hands-off reading

npm install
npm run dev

App runs at http://localhost:3000 in the browser. For the desktop app shell, use Tauri dev:

npm run tauri:dev

This repo uses Tauri v2. Building will first produce the static Next.js output into out/, then Tauri bundles per platform into src-tauri/target/release/bundle.

Common command on any platform:

npm run tauri:build

Outputs by platform:

• macOS: .app and .dmg under src-tauri/target/release/bundle/macos and bundle/dmg
• Windows: .msi by default (WiX). Optional .exe installer via NSIS if NSIS is installed

Unsigned builds are quarantined by Gatekeeper. After moving the app to Applications, remove quarantine once:

xattr -dr com.apple.quarantine "/Applications/Blip RSVP Reader.app"

Then open it normally from Applications. Signed/notarized builds from Releases won’t require this step.

• Rust (via rustup)
• Node.js 18+
• macOS: Xcode Command Line Tools (xcode-select --install)
• Windows: Visual Studio Build Tools (Desktop C++ + Windows SDK) and either WiX v3 (for .msi) or NSIS (for .exe)

This is a personal tool to help me read books faster using RSVP. It favors simplicity and local-first files. There’s no cloud sync or login.

Personal use. Ask before redistribution.
