A complete text laboratory in three steps
No AI provider, no credits and no registration — the analysis runs on your device.
Read the analysis
Counts, readability, repetitions, keywords and structure update as you type.
Clean and hand off
Apply reversible cleanups, undo anything, and send the result to the corrector, summarizer, paraphraser or comparator.
More than a word counter
Objective signals and mechanical fixes with zero provider cost.
Private by construction
Pasted text never leaves the browser; analysis runs in a local Web Worker.
Language-aware metrics
Uses the browser segmenter for CJK, Thai and RTL, with per-language readability formulas.
Honest readability
Estimates are labeled as estimates — never disguised as an AI-detection score.
Reversible cleanup
Every change is previewed, applied deterministically and undoable to the exact original.
