Igbo Keyboard — Tone Marks & Diacritics

Add correct Igbo diacritics (tone marks) to your writing on any website. Runs on your device — your text is never sent anywhere.

Write proper Igbo anywhere in Chrome — email, social media, docs, forms — with correct diacritics and tone marks added for you. Igbo is tonal, and the marks matter: they change meaning. This extension fixes them for you as you write. • Click the "IG" button that appears on any text field, or press Ctrl+Shift+D (⌘+Shift+D on Mac), to add diacritics to what you've typed. • Works on every website. • Undo with Ctrl+Z to get the original back. • Quick-diacritize box in the toolbar popup for pasted text. Privacy first: diacritization runs entirely on your device using a built-in dictionary. Your text is never sent to any server. We collect only anonymous usage counts (never your text) to see how many people use the extension.
