## What it is
Glance (formerly OpenSpritz) is a speed-reading bookmarklet that displays web page text word-by-word using RSVP (Rapid Serial Visual Presentation) techniques. It is implemented in JavaScript and injected into any page via a bookmarklet.

## Use cases
- read articles faster with RSVP speed reading
- add speed reading to any web page via bookmarklet
- spritz-style word-by-word reading in the browser
- consume news content more quickly
- speed read long text without installing an extension

## When to choose
- you want a lightweight, install-free speed reading tool for the browser
- you prefer bookmarklets over browser extensions
- you want an open-source Spritz-style reader

## When to avoid
- you need a maintained tool - the project has had no releases since 2018 and points to the successor Glance project
- you need a full browser extension with UI integration
- you need offline or mobile-native speed reading
