Spanish text difficulty checker
Paste any Spanish text here — a news article, a song lyric, a chapter from a novel — and Beeblio will break it down by word frequency. Each word is assigned to a band based on how commonly it appears in real Spanish: the 300 most frequent words, then up to 800, 1,500, 3,000, and beyond. Words you likely already know light up differently from the ones that are new or rare, so you can see at a glance whether a text is comfortably within your reach or a genuine stretch.
The frequency ranks come from the wordfreq corpus, which draws on a wide range of real-world Spanish — books, websites, subtitles, and more. Because the ~1,500 most frequent Spanish words cover around 80% of everyday text, the bands give you a meaningful picture of how much of a passage you can expect to understand at your current level.
Use the checker before you read: if most unknown words fall in the 800–1,500 band, the text is probably ideal for your level. If you're seeing a lot of 5,000+ words, it might be worth saving it for later — or using it as a targeted vocabulary challenge.
How it works
Paste a text in Spanish (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
How does Beeblio decide which band a Spanish word belongs to?
Every word is looked up in the wordfreq corpus, a large dataset built from real Spanish text across books, websites, and subtitles. Its rank in that list determines its band — for example, a word ranked inside the top 300 falls in the first band, while one ranked between 3,001 and 5,000 falls in the fifth.
What level of Spanish learner is this tool useful for?
It's useful at any level, but it's especially handy for A2–B2 learners who want to apply comprehensible-input principles — choosing texts where they already understand most words but still encounter some new ones. Beginners can check whether a text is too advanced, while intermediate learners can spot the specific vocabulary gaps worth studying.
Does the checker handle verb conjugations and other word forms correctly?
Yes. Beeblio lemmatises each word before looking it up, meaning a conjugated form like <em>estuvieron</em> is correctly linked to its base form <em>estar</em> for frequency ranking. This gives you an accurate picture rather than marking common verbs as rare just because they appear in an unfamiliar form.
