Tashkeel Studio

Auto Arabic diacritics, offline.

• Android
• Windows
• Linux

Add full diacritics to Arabic text automatically with our own on-device model for modern Arabic, plus a classical style for heritage texts — private and offline.

What it does

• Our own diacritization model for modern Arabic — news, articles, letters and study texts — trained by us and running entirely on your device
• A second style for classical, religious and heritage texts, one tap away
• Reads each paragraph as a whole, so a word's vowels follow the sentence around it
• Keeps every mark you already wrote (such as a shadda) and fills in only the rest
• Tanwin, fatha, damma, kasra, shadda and sukun; long texts are handled paragraph by paragraph
• 100% offline — your text never leaves the device; paste, sample, clear and one-tap copy
• Bilingual Arabic/English interface
