Add tashkeel to Arabic text, free

How to add tashkeel with this tool

1. Paste or type Arabic text in the first box. You can do 5,000 characters at a time; split longer text into parts.
2. Press Add tashkeel. The first time, the engine downloads to your browser once; after that a paragraph takes under a second.
3. Check the result and fix anything: put the cursor after a letter and pick a mark from the buttons, then copy the text.

Which marks does it add?

The tool adds the eight marks people mean by tashkeel (also called harakat or Arabic diacritics), on every letter that needs one:

If your text has no hamzas at all, as is common when typing on a phone (اصبح, الى), the tool suggests the missing ones (أصبح, إلى). If your text already has hamzas, it leaves your spelling exactly as it is.

How accurate is automatic tashkeel?

We tested the tool on modern news text vocalized by experts, the WikiNews benchmark: about 16,000 words. It got about 83% of words fully right, and about 90% if you don't count the last letter's mark (the grammatical case ending).

So roughly one word in six may need a fix with full case endings. Treat the result as a mostly accurate draft, and check it before you print or record it.

Where it usually goes wrong

• Imperative verbs: «اكتب» (write!) can come out as «أكتبُ» (I write).
• Names and foreign words, such as people's names and brands.
• Case endings in long or complex sentences.
• Words with more than one reading, like «عِلْم» (knowledge) and «عَلَم» (flag), when the context isn't enough.
• Dialect: the model was trained on Modern Standard Arabic.

When to use Pause on word endings

Read aloud naturally, or in dialect, Arabic speakers usually don't pronounce the case ending on the last letter; they stop on it with a sukun. This option vocalizes the text that way, and it also removes the hardest part of tashkeel, so you'll have fewer errors to fix.

Our guide covers tashkeel rules for voiceover in more detail.

How to type tashkeel yourself

On the Windows Arabic keyboard, type the letter, then press Shift with one of these keys:

The same shortcuts work in Word. For a long text, add tashkeel here, then copy and paste it into Word; the marks stay as they are.

Your text stays on your device

The tashkeel engine downloads to your browser and runs there, so your text isn't sent to us or anyone else, and we don't store it. We only record anonymous usage numbers, such as character counts and processing time, to improve the tool.
