How it works

A simple loop: look up, queue, remember.

Ikhou is designed around the material you already use, not a canned curriculum.

01

Look up words anywhere

Use the extension while reading, watching, or listening. Capture the word in the place you found it.

02

They land in your queue automatically

Saved words sync into Ikhou with their sentence context, ready for review when you are.

03

Review until they stick

Use spaced repetition, targeted tutors, and calm repetition to turn lookups into memory.

Built for real immersion

Built for learners who want progress, not points.

Ikhou keeps the visual language calm and earnest while tightening the experience around real study habits.

No streaks. No XP. No fake urgency.

The product tells the truth about what is due. You review because it matters, not because a game mechanic is yelling at you.

Your content, not ours.

Ikhou is strongest when it follows the media, articles, subtitles, and notes you already care about.

Spaced repetition that adapts to you, not a schedule.

The algorithm adapts quietly in the background while the content and context stay yours.
