## What it is
RSVP Nano is an open-source pocket-sized speed-reading device built on ESP32 that presents text one word at a time using Rapid Serial Visual Presentation, with page-reading mode as an alternative. The project includes multi-board ESP32 firmware plus Compose Multiplatform web, Android, and iOS companions for setup, flashing, and library management, backed by a shared Kotlin conversion engine for EPUB, text, Markdown, HTML, and XHTML files.

## Use cases
- read books faster with RSVP speed reading on a dedicated device
- convert EPUB and Markdown files for reading on an ESP32 e-reader
- flash and manage firmware on a pocket speed reader
- read CJK, Arabic, or Hebrew text with proper shaping on a small device
- sync reading progress and settings over Wi-Fi or USB
- load custom fonts, themes, and language packs onto a microSD reader

## When to choose
- you want a dedicated, offline, pocket-sized speed-reading device
- you enjoy DIY ESP32 hardware projects and want a polished reader firmware
- you need multilingual reading support including RTL and vertical CJK text
- you want companion apps to manage your library, fonts, and firmware updates

## When to avoid
- you want a mainstream, commercially supported e-reader out of the box
- you need a mature 1.x release line; the project is still on 0.x with breaking changes
- you prefer reading on a phone or desktop rather than dedicated hardware
- you are not comfortable flashing firmware and managing microSD cards
