Is it clear and tight?

The checks that most change how a sentence reads. Start here if the English is correct but heavy.

Passive Voice Checker Flags every passive-voice sentence so you can make your writing more direct. Wordiness Checker Flags redundant phrases and suggests shorter alternatives. Run-on Sentence Checker Finds comma splices and fused sentences, and shows the join to fix. Repeated Words Checker Finds accidentally doubled words like «the the» that spell-check misses. Readability Checker Flesch Reading Ease, grade level, and an estimated CEFR / IELTS band.

Does it sound like a native wrote it?

Grammatically correct English can still read as translated. These find the patterns that give it away.

«Sounds Translated?» Checker Check if your English sounds natural or translated, with exact phrases to fix. False Friends Checker Flags false cognates from your language that pass grammar checks but change your meaning. Sentence Structure Checker Sentence length spread, repeated openers, fragments and monotony. Native Language Detector A playful guess at the writer’s first language from English error patterns.

Will it be flagged as AI?

What detectors and markers actually react to — and, honestly, what they cannot tell you.

Why It Reads as AI The specific sentences a detector reacts to, and the ESL habit behind each. ChatGPT Words Checker Highlights overused AI words and phrases — with an honest verdict.

Counts and mechanics

Small, exact utilities for when you need a number or a tidy-up.

Word Counter Live word, character, sentence and reading-time counts as you type. Syllable Counter Instant syllable count per word, per line (haiku 5-7-5), and in total. A vs An Checker Flags «a»/«an» that disagree with the sound of the next word — «an university», «a hour». Text Cleaner Removes double spaces, fixes punctuation spacing, and tidies quotes.

Guides behind the tools

Free tools — questions

Are these tools really free?

Yes — no signup, no word limits, no trial clock. They are small, self-contained utilities that run entirely in your browser, so they cost us almost nothing to serve. We build them for the checks non-native writers do every day; some writers later want the full editor, and that is the whole business model.

Is my text uploaded or stored anywhere?

No. Every tool on this page runs locally in your browser — the text never leaves your device, nothing is sent to a server, and nothing is stored. The paste box at the top of this page is the same: your text is held in this browser tab only, handed to the tool you pick, and dropped when the tab closes. You can verify all of it yourself — the checkers keep working with your internet connection switched off.

How are these different from the Diglot editor?

The tools diagnose; the editor fixes. A checker can tell you a sentence is passive, wordy, or sounds translated — rewriting it while keeping your meaning is the hard part, and that is what Diglot does: grammar correction, rephrasing, and inline translation from your first language, in one place.

Want more than a quick check?

These tools show you what to fix. Diglot fixes it — grammar, phrasing, and the translated patterns that give non-native writing away — while keeping your meaning and voice.
