Portuguese text difficulty checker
Paste any Portuguese text here and Beeblio will instantly show you how much of it falls within your current vocabulary range. Every word is matched against frequency data from the wordfreq corpus and sorted into bands — 300, 800, 1,500, 3,000, 5,000, 8,000, and 12,000 most-common words — so you can see at a glance whether a news article, a short story, or a song lyric is within comfortable reach or a genuine stretch.
The results tell you two things that matter most for comprehensible-input learning: how large a share of the text you likely already understand, and exactly which words are new or rare for your level. Research suggests that knowing around the 1,500 most frequent words of a language gets you through roughly 80% of everyday text, so even a small vocabulary goes further than most learners expect.
Use the difficulty checker to pick texts that challenge you just enough — not so easy you stop noticing language, not so hard you lose the thread. Spot the unknown words, look them up, then read with confidence.
How it works
Paste a text in Portuguese (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 for my reading?
Each band groups words by how commonly they appear in real Portuguese — so a word in the top 300 turns up constantly, while one beyond 5,000 is something most native speakers rarely write. If most of a text falls inside your known band, you can read it comfortably; a cluster of words in higher bands tells you where you'll need a dictionary or extra study.
Does the checker work for both European and Brazilian Portuguese?
The frequency data from the wordfreq corpus draws on a large mix of Portuguese-language sources, which includes both European and Brazilian writing. For very region-specific vocabulary or slang, rankings may vary slightly, but the results are a reliable guide for learners of either variety.
Can I use this to choose graded readers or authentic texts at the right level?
Absolutely — that's one of the most practical uses. Paste an excerpt from a book, article, or podcast transcript and check what percentage of words sit inside your current band. Aim for texts where the vast majority of words are already familiar, with just a handful of new ones to push your vocabulary forward.
