The Problem

Why Most Vocabulary Apps Leave You Stuck

📖

Translations Without Context

Getting a word in your native language doesn't show you how to use it, when to avoid it, or how it sounds in a real sentence. That's not learning — it's guessing.

🔒

Forced Paths, Not Your Words

Pre-built courses and daily streak pressure ignore the words you actually encounter. Real vocabulary building is personal — your tool should be too.

👁️

Your Data as the Product

Most apps demand an account before you can start. They track you, target you, and lock the good stuff behind a subscription wall.

The Solution

A Dictionary Built for Committed Learners

Most apps give you a single word and move on. OpenWords gives you the linguistic depth to go from just understanding to actually being fluent.

Save the exact meaning that fits your context — not just the top definition.

Word families

Instantly see related roots, compounds, and derived forms to expand your vocabulary naturally.

CEFR levels & frequency

See at a glance if a word is A2 or C1. Know if it's High or Low frequency to prioritize what matters.
