Tashkeel that follows the grammar
Arabic is normally written without its short vowels, which is fine once you know the language and awkward while you are still learning it. This tool restores them — and it does so by reading the sentence, so the case endings match the grammatical role each word is actually playing rather than the form it has in a dictionary.
When to use full, and when to use light
- Full suits reading practice, worksheets for beginners, and anything that will be read aloud.
- Light suits fluent readers: it marks only what would otherwise be genuinely ambiguous, which is closer to how printed Arabic handles it.
What it will not do
It will not rewrite, translate or correct your text. If a word is misspelled it stays misspelled, with vowels on it — which is usually what you want, because silent corrections are worse than none.
Read more about this
- Tashkīl: how much to leave on, and when to take it off — Real Arabic is written without vowels. Full vowelling forever produces learners who cannot read anything published; removing it too early produces guessing. A staged plan for getting from one to the other.
- Pitching an Arabic reading text at the right level — What actually makes an Arabic text hard, the unknown-word percentages worth aiming at, and how to bring a real text down a level without turning it into Arabic nobody writes.
- Arabic case endings: what they are for and when to teach them — Iʿrāb is invisible in most writing and dropped in most speech, which makes it easy to teach at the wrong time. Where the cases are actually audible, what they buy a reader, and why insisting on them early costs fluency.
Common questions
How accurate is it?
Very good on modern standard Arabic and classical prose, and reliable on Qur'anic text it has seen. Poetry and rare classical vocabulary are where mistakes cluster, so check the case endings on anything you are publishing.
Can I diacritise a whole book?
Not in one go — each run takes up to about 4,000 characters. Work section by section, which also makes the output easier to check.
Does it work with Qur'anic orthography?
It handles ordinary Arabic script well. For the Qur'an itself, use a verified mushaf text — automatic diacritisation is not an acceptable substitute for a published edition.
