Analizador de Complejidad de Oraciones
Analiza la complejidad de tus oraciones por longitud y dificultad de palabras
A sentence complexity analyzer rates how complex your writing is, based on sentence length and the proportion of longer words. Complexity is not the same as quality — sometimes you want dense, sophisticated prose, and sometimes you want it short and punchy — but knowing where your writing sits helps you match it to your audience.

Analizador de Frecuencia de Palabras
Cuenta con qué frecuencia aparece cada palabra en un bloque de texto
A word frequency analyzer counts how often each word appears in a block of text and shows you the most common ones. Frequency analysis is a quick way to see what a piece of writing is really about, to catch words you overuse, or to pull keywords from a document.

Analizador de longitud de oraciones
Analiza la longitud de las oraciones y marca las demasiado largas para dividirlas
A sentence length analyzer breaks your text into sentences and measures each one, so you can see and fix the rhythm of your writing. Paste any text and it reports the number of sentences, the average length, the shortest and longest, and flags every sentence over thirty words as a candidate to split.

Contador de frecuencia de palabras
Cuenta con qué frecuencia aparece cada palabra en un texto y clasifica las más comunes
A word frequency counter tallies how often each word appears in your text and ranks the most common, skipping filler words like the, and, and of so the results show what your writing is really about. Paste any text, choose how many top words to see, and it returns a ranked list of the most-used terms with their counts.

Contador de palabras
Cuenta palabras, caracteres, oraciones, párrafos y tiempo de lectura de cualquier texto
A word counter measures your text the moment you paste it: total words, characters with and without spaces, sentences, paragraphs, and an estimated reading and speaking time. It is the quick check writers reach for when a brief sets a strict limit — a 300-word product description, a 160-character meta tag, a 500-word essay, or a two-minute speech.

Contador de Sílabas
Estima el número de sílabas en una palabra o frase
A syllable counter estimates how many syllables are in a word or phrase. Syllable counts matter for poetry, songwriting, and language learning — a haiku needs five, seven, and five — yet counting them by ear is surprisingly error-prone.

Generador de eggcorns
Lista eggcorns —errores lógicos de oído— junto a la expresión correcta
An eggcorn generator collects those mishearings where a person replaces a word or phrase with one that sounds similar and, crucially, still seems to make a kind of sense — like writing "old-timer's disease" for Alzheimer's. Choose how many you want and it lists each eggcorn beside the correct version so you can see both the slip and the standard form.
