Three ways to translate, wherever you read

Persian to English and English to Persian, with the direction detected for you. Your original page is never changed.

Point at a paragraph

Rest your pointer on a paragraph or heading and a small icon appears. Click it and the Persian arrives underneath, so you read both side by side.

Or press Alt+B

Select any text

Highlight a word or a passage. ParsiPad reads the sentence around it first, so a word gets the sense that fits, with pronunciation and examples.

Use the selection toolbar, or press Alt+T

Translate the whole page

ParsiPad tells you how many paragraphs there are and roughly what it will cost before it starts. Switch back to the original whenever you like.

Right-click, or press Alt+P

  • Screenshots. Press Alt+S and drag a box over text you cannot select.
  • Images and documents. Drop or paste an image, or a .txt file to translate in full.
  • A side panel. Docked beside the page, it stays open while you browse.

Learn as you go, keep what you learn

Built for Persian speakers learning English, so every translation can teach you something.

  • Grammar lessons

    Any translation can explain itself. Open a full lesson with examples, pronunciation and a quiz built around the mistakes Persian speakers actually make.

  • Dictionary

    Definitions, IPA pronunciation, synonyms and the Persian or English equivalent for any word. Press Alt+D.

  • Polish your writing

    Rewrite what you wrote as professional, conversational or concise English, regenerate any version you do not like, and put the one you pick straight back where you typed it.

  • Library

    Everything you translate, look up or polish, plus your favorites and saved lessons, in one searchable place.

  • Flashcard practice

    Star a translation and it becomes a flashcard. Flip with Space, move with the arrow keys, and choose how many cards a session holds.

  • A word on every new tab

    Each new tab shows one of your saved words to recall, with your bookmarks a keystroke away. Prefer your browser's own page? Switch it off in Settings.

A New Tab page with the time, a greeting in English and Persian, and the saved word تاب‌آور to recall.

A closer look

The Persian, right under the English

Rest your pointer on a paragraph, click the icon, and the translation arrives underneath it. The page itself stays exactly as it was, so you read both side by side.

Or press Alt+B

The meaning that fits the sentence

Select a word and ParsiPad reads the sentence around it first, so you get the sense that was meant, with pronunciation, a usage note, examples, synonyms and opposites.

Use the selection toolbar, or press Alt+T
