Observed free-editor coverage
Hemingway's free editor focuses on readability and style. In this same-input check, it did not provide the expected grammar correction for any of the eight errors.
For each example, we used the same American-English input with both tools and compared their outputs with the expected minimal correction. These examples are not an overall accuracy ranking.
Refine v1.34 with Gemma 4 E2B and Hemingway free web editor, observed 2026-07-31; both using American English.
The local language-model output matched the expected minimal correction in all eight examples. Hemingway's free editor supplied no grammar correction; one input received only a generic adverb highlight.
The noun “decision” needs the adjective “quick” here, not the adverb “quickly.”
Text to check
The team made a quickly decision before noon.
Expected change
Local language model: Caught
Changed “quickly” to “quick.”
Hemingway free editor: No grammar correction
Highlighted “quickly” as an adverb, but did not identify that “quick” was needed before the noun. The visible correction action was “Fix this with AI.”
The pronoun is the direct object of “thanked,” so it needs the object form “her,” not “she.”
Text to check
The courier thanked she for the detailed note.
Expected change
Local language model: Caught
Changed “she” to “her.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
The plural subject “doors” takes “have,” not the singular form “has.”
Text to check
The warehouse doors has closed for the night.
Expected change
Local language model: Caught
Changed “has” to “have.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
After the modal “must,” English uses the base verb “check,” not “checks.”
Text to check
The driver must checks the mirrors before leaving.
Expected change
Local language model: Caught
Changed “checks” to “check.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
When “arrive” names a destination, English normally introduces that destination with a preposition such as “at.”
Text to check
The delivery truck arrived the warehouse before dawn.
Expected change
Local language model: Caught
Changed “arrived the warehouse” to “arrived at the warehouse.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
A direct “why” question with an ordinary verb needs “did” before the subject, with the main verb in its base form.
Text to check
Why the meeting ended early?
Expected change
Local language model: Caught
Changed “Why the meeting ended” to “Why did the meeting end.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
The time word “yesterday” calls for the finite past form “wrote.” “Written” is a participle and cannot stand alone as the finite verb here.
Text to check
The clerk written the final note yesterday.
Expected change
Local language model: Caught
Changed “written” to “wrote.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
To negate this infinitive, “not” belongs before “to.” The finite form “don't” cannot fill that position.
Text to check
The host asked us to don't open the side door.
Expected change
Local language model: Caught
Changed “to don't” to “not to.”
Hemingway free editor: No grammar correction
No relevant grammar finding or correction; the error stayed unchanged.
Refine is a better fit when you want contextual writing help where you already type, backed by a local model and a one-time license.
Hemingway is a better fit when a dedicated document editor, grade-level score, and clear style highlights are central to your process.
Hemingway already offers a free web editor for readability scoring and style highlights. Refine is a paid Mac app with a full-featured trial, local AI models, and writing help across many apps rather than only inside a dedicated editor.
Refine's local models work offline after download. Hemingway Desktop 3 also works without internet, but its official page says it does not include the newer AI features. Hemingway describes Editor Plus AI as cloud-based.
Refine runs downloaded AI models on your Mac, so checked text is not uploaded to Refine servers. Editor Plus sends relevant content through Hemingway and an LLM host, but Hemingway says it discards document content after processing and prohibits training. Its separate Classic app stays on-device without the newer AI features.
No. In our scoped eight-input check, the free editor supplied no grammar correction. It highlighted “quickly” as an adverb in one sentence, but did not identify that the adjective “quick” was required; the visible correction action required AI. This result does not evaluate Editor Plus.
Choose Hemingway when you primarily edit English documents and want its readability grade, document statistics, color-coded style highlights, and import or export workflow.
Choose Refine when you want private local AI across most Mac apps, offline grammar and fluency help, support for more than 50 languages and variants, translation, explanations, and custom prompts.
