## What is Text Transformer?

FEATURES:
- Automatically split sentences into shorter ones and align them (left or right)
- Extract and comprehensively highlight important words in multiple colors
- One-click operation for both features
- Manual highlighting by simply tapping on a word


USE CASES:
1. Language Learning
 1.1. Breaking down problems
 - Sentences are divided into smaller parts, allowing you to tackle each piece at your own pace.
 - Always starting from the beginning of a sentence makes it easier to read.

 1.2. Identifying key words
 - Highlighted important words help you know which words to look up first in a dictionary.
 
 1.3 Reducing the number of unknown words (e.g., from 90 to 60)
 - While it may seem like there are many unknown words, there are actually fewer due to repetitions.
 - Important words often repeat.
 - Highlighting key words ensures they are counted only once.
 - In the example image, the number of unknown words is reduced from 90 to 60.

 1.4. Contextual learning
 - Learn important words along with surrounding words.
 - It's more efficient to learn related words together rather than in isolation.
 - For instance, in the example image, verbs like "provide," "introduce," "delve," "explain," and "cover" follow the word "Chapter."
 - This helps you understand subtle differences in meaning among similar words.

 All these tasks are automated with just one click. 
 If you need more highlights, simply tap the word to add it manually. 
 No need for keyboard or menu operations, allowing you to stay focused on learning and reading.

2. Reading Specialized Fields
 Similar to language learning, reading specialized fields in your native language can be as challenging as learning a foreign language.


KEY FEATURES:
- Works on nearly all web pages.
- Study topics you're interested in using your favorite texts. 
- Wikipedia articles are particularly recommended.


ADDITIONAL FEATURES:
- Safari extension

- One-time purchase, no additional charges
 - Not a subscription
 
- No ads

- No server communication
 - Complete privacy protection
 - Fast processing
 
- iOS exclusive
 - macOS support coming soon. 
 - These will be the only platforms supported with a one-time purchase.
 - No free version on Chrome Store or other platforms planned. 
 - We ensure fairness for iOS and macOS users.
