Simplify an English paragraph by replacing complex words and splitting long sentences, with Flesch before and after
Rule-based Rewriter
Rewrite English text with rules (no AI): limited synonym replacement, simple passive-to-active conversion and conditional reordering, with locked terms that never change and three strictness levels.

Result
How the result is calculated
Three layers apply by level. (1) Synonyms: a limited dictionary (about 25 common words) keeping letter case. (2) Conditional: If A, B. ↔ B if A.. (3) Simple passive in the pattern The X was Yed by the Z. → The Z Yed the X. for regular -ed verbs in the past only. Locked terms are masked before any change and restored as they were afterwards.
Limits:
The tool does not claim “undetectable” by any AI detector (they are unreliable). Synonyms ignore context and may give unnatural sentences, and passive conversion works only for the simple pattern. For real-quality rewriting use a language model and human review. English only.
