Sentence Complexity Analyzer

Analizador gratuito de complejidad de oraciones. Mide la profundidad media de cláusulas, recuento de oraciones subordinadas, clasificación en simple/compuesta/compleja, tasa de voz pasiva y muestra las estructuras más extensas.

Cuándo usarlo

Use when your text feels hard to read but you can't pinpoint why. A high clause depth combined with high passive count is the classic recipe for "dense" prose.

Cómo se compara

Where readability formulas give a single grade, this tool tells you what *kind* of complexity drives it — subordination, coordination, or length.

Cómo funciona

Each sentence is tokenized and counted for subordinating connectives ("because", "although"), coordinating connectives ("and", "but"), and passive constructions.

Clause depth is roughly 1 + subordinate clause count. Sentences with no connectives are "simple"; with only coordination they're "compound"; with any subordination they're "complex".

Splits surfaced are sentences over 35 words or with three or more subordinate clauses — typical candidates for trimming.

Preguntas frecuentes

What does clause depth measure?

Roughly how many clauses each sentence contains. A sentence with two subordinate clauses has depth 3.

What grade level does this map to?

Not directly — use a readability formula for that. This tool is about syntactic complexity, which can be high in clear writing or low in unclear writing.

Why does it flag passive voice?

Heavy passive voice and deep subordination both increase parsing load. The split suggestions surface sentences that combine both.

Ejemplo práctico

Entrada

Although the meeting ran long, we covered every agenda item. Decisions were made. The team left energized.

Salida

Avg clause depth: 1.67 — Simple. Mix: 2 simple, 0 compound, 1 complex.

One subordinate clause ("Although the meeting ran long") gives sentence 1 a depth of 2; the other two are depth 1. The blend reads as varied but accessible.

Errores comunes

  • Heuristic detection — does not parse syntax fully.
  • Dialogue confuses the simple/compound classifier (heavy "and" usage).
  • Long sentences without subordination are not flagged — only deep nesting is.
