Find machine-sounding prose

Yapaysız is a writing editor for Turkish and English. It marks the sentences that read as machine-made — stock phrases, formulaic connectors, uniform rhythm — tells you why, and helps you say them your way. Everything happens on your Mac.

Mac App Store — soon How it works

The editor with flagged sentences underlined and the inspector explaining the first one: stock phrase, filler phrase, vague word, and how to fix them — Every flagged sentence gets a wavy underline and a plain explanation: what fired, and how to fix it.

The document panel: a complexity score, readability formulas, vocabulary measures, sentence lengths and a heatmap — Style, measured: readability, vocabulary, sentence lengths, rhythm and a heatmap of the whole document.

The Style lens: clichés and filler words underlined in the text and listed in the inspector with notes — Lenses show one kind of finding at a time — here clichés and filler words, each with a short note.

The Spelling lens: a misspelt word underlined with the Mac's suggestions beside it — Words your Mac's dictionary does not know, with its own suggestions, one click to replace.

How it works

Write or import. Type, paste, or import Word, PDF, text and Markdown. The analysis runs as you write.
See why a sentence sounds artificial. Each flagged sentence names its signals — a stock phrase, a filler connector, a run of sentences of the same length — and says how to fix it. ⌥⌘↓ jumps to the next one.
Style, measured. Ateşman, Çetinkaya-Uzun and Bezirci-Yılmaz for Turkish; Flesch, Gunning Fog, SMOG and others for English; vocabulary richness, sentence lengths and rhythm.
Findings, through lenses. Words not in your Mac's dictionary, English words in Turkish text with Turkish equivalents, repetition, long sentences, academic heaviness, redundant phrases, filler words, clichés and particles written together (de/da, ki, mi). Add your own rules.
Rewrite, on device. With Apple Intelligence, Yapaysız suggests a rewrite, scores it again and warns you if a word, a name or a number may have gone missing. Nothing changes until you accept; every change is one undo step.
Read it back. A speed reader, a Markdown report, and a change list for imported documents.

What it does not do

No account, no server, no network. Your text never leaves your Mac
Its scores describe style. They are not proof of who wrote a text, and Yapaysız does not claim to be one
It never changes your text without you: every suggestion waits for Accept
Rewriting needs Apple Intelligence; without it everything else works the same

Turkish and English. Requires macOS 26 on Apple silicon. One payment, no subscription.
