Ukrainian text difficulty checker
Paste any Ukrainian text here and Beeblio breaks it down by word frequency in seconds. Each word is assigned to a band — the 300, 800, 1,500, 3,000, 5,000, 8,000, or 12,000 most common words in Ukrainian — based on the wordfreq corpus. You'll instantly see what share of the text sits within your current vocabulary and which words are likely new or rare.
This matters because of how comprehensible input works: if you already know around 95–98% of the words in a passage, you can read it comfortably and pick up the rest from context. The difficulty checker shows you at a glance whether a Ukrainian article, story, or textbook excerpt is just right for your level, a little above it, or still out of reach.
Use it to choose what to read next, to spot the high-frequency words still missing from your vocabulary, or to track how your reading level grows over time. No account needed — just paste and go.
How it works
Paste a text in Ukrainian (up to 6,000 characters). Every word is looked up in a frequency list; for each band — the top 300, 800, 1,500, 3,000, 5,000, 8,000 and 12,000 words — you see the share of the text a learner at that band already knows. Comprehensible reading sits around 95–98% known: we call ≥97% easy, 92–97% just right, 85–92% hard, and below that too hard.
You also get the new words worth learning (unknown but common, in frequency order) and the rare words — names, jargon, typos — that no learner should stop for.
Questions
What do the frequency bands actually mean?
Each band groups words by how commonly they appear in real Ukrainian text. The top 300 words are the most everyday — think conjunctions, pronouns, and basic verbs — while words beyond 5,000 are much rarer and mostly crop up in specialised or literary writing. Knowing the top 1,500 words typically covers around 80% of everyday text.
My text contains proper nouns and names — will they skew the results?
Proper nouns, place names, and personal names are often ranked as rare or unknown because they don't appear frequently in general corpora. It's worth bearing this in mind: a news article full of politician names or city names may look harder than it really is for a reader who already knows those words.
How is this different from just looking words up in a dictionary?
A dictionary tells you what a single word means; the difficulty checker gives you the full picture of a whole text at once. You can see patterns — for example, that a text is mostly within your reach except for a cluster of rare verbs — which helps you decide whether to read it now or save it for later.
