Best forWriters and teams who draft their own text and want it shorter, plainer and easier to read, with optional AI fixes, rather than an AI that writes marketing copy from a brief.Novelists and other fiction writers who want detailed line editing and AI feedback on chapters and full manuscripts, rather than an AI that drafts marketing copy for them.

Hemingway Editor and ProWritingAid both date from 2013, and both focus on improving writing you already have rather than drafting it for you. Hemingway's free online editor scores readability and highlights hard-to-read sentences, passive voice and words with simpler alternatives; its paid Plus plans add AI rewrites, grammar fixes and tone changes. ProWritingAid is a toolkit for storytellers: a grammar checker, 25+ line-editing reports and AI feedback on chapters and whole manuscripts. Below are their US prices, free tiers, trials, integrations, add-on costs and privacy statements, taken from each vendor's own pages as of October 2026.

Test 1: Flag 8 planted readability problems in a FICTIONAL notice

· MacBook Pro (M1 Pro), macOS 26.6.2, Chrome 155

The task

Paste this FICTIONAL notice, which has 8 planted readability problems, into each tool on its free plan and record which problems it flags:

The Fernhill community garden closes for repairs on Saturday, May 9. The gate locks were replaced by the council last week. New keys will be handed out by the office on Monday. Members who have not yet picked up their seed packets from the shed next to the greenhouse should collect them before five o'clock on Friday, May 8, because after that time the volunteers need the whole shed for the spring repairs and the new shelves. Tools left in the shed after that time will be moved to the office. We will utilize the empty shed for seed storage. Volunteers will commence work at 8 a.m. The office is open for approximately four hours a day. If you need a key and you cannot come to the office during its opening hours on a weekday, you can send a message to the garden secretary, who will try to find a time that suits you and meet you at the gate on a weekend morning instead.

How we judged it

A problem counts as flagged when a highlight or a report suggestion points at it (the 8 are listed in the steps). A flag shown only behind a paid-plan lock counts as not flagged.

Pass: 7 or 8 flagged.

Partial: 4 to 6 flagged.

Fail: 3 or fewer flagged.

Hemingway Editor

Partial 5 of 8

Plan: Editor Plus (14-day trial) · Web editor (hemingwayapp.com)

Flagged both long sentences, "were replaced", "utilize" and "commence"; missed two of the three passives and "approximately". Grade 7.

Hemingway Editor with the garden notice highlighted and its readability counts
Two red sentences, one passive and two simpler-word highlights.

ProWritingAid: Winner

Partial 6 of 8

Plan: Free · Web editor; Readability, Style, Sticky Sentences reports

6 of 8: the Style report marks all 3 passives, "approximately" and the long "If" clause; Sticky Sentences marks both long sentences; missed "utilize" and "commence".

ProWritingAid Style report and Sticky Sentences report on the garden notice
Three passives underlined in the Style report; the two long sentences are sticky.
ProWritingAid Readability report on the garden notice
Flesch Reading Ease 74.7 and Flesch-Kincaid Grade 8.0: "This document is easy to read."

Hemingway ran on the account's Editor Plus trial (the highlights are the free editor's). ProWritingAid reports used: Readability, Style and Sticky Sentences; the long "Members who..." sentence is marked as a sticky sentence.

Test 2: Score the readability of the Gettysburg Address

· MacBook Pro (M1 Pro), macOS 26.6.2, Chrome 155

The task

Paste the Bliss copy of Abraham Lincoln's Gettysburg Address (the text at abrahamlincolnonline.org, the first copy on the page) into each tool on its free plan, and record the readability result it gives for the whole text and the sentences it marks as hard to read.

How we judged it

Pass: a readability score or grade level for the whole text, and the hardest sentences marked in the text.

Partial: only one of the two: a score without marked sentences, or marked sentences without a score.

Fail: neither on the free plan.

Hemingway Editor: Winner

Pass

Plan: Editor Plus (14-day trial) · Web editor (hemingwayapp.com)

Grade 12 ("OK. Aim for 9"); marks 2 of 10 sentences as very hard and 3 as hard to read in the text.

Hemingway Editor with the Gettysburg Address highlighted red and yellow, and Grade 12
Red for the first and last sentences, yellow for three more.

ProWritingAid

Partial

Plan: Free · Web editor, Readability report

Flesch Reading Ease 67.9 and Flesch-Kincaid Grade 10.5, but no sentence is marked hard; it rates two paragraphs as easy to read.

ProWritingAid Readability report on the Gettysburg Address with its two scores
"This document is easy to read": Flesch Reading Ease 67.9, Flesch-Kincaid Grade 10.5.
ProWritingAid card on the second paragraph saying it is easy to read
Marks are per paragraph; no sentence is flagged as hard.

Speech text of the Bliss copy (278 words). ProWritingAid scores paragraphs, not sentences.

Test 3: Fix 10 planted grammar and spelling errors in a club notice

· MacBook Pro (M1 Pro), macOS 26.6.2, Chrome 155

The task

Paste this FICTIONAL paragraph, which has 10 planted errors, into each tool and accept its grammar and spelling fixes:

The Fernhill book club meet on the first Tuesday of every month. This month we are reading a novel about a lighthouse keeper and his daugther. Everyone are welcome, even if you hasn't finished the book. Please bring you're own cup; the library dont provide them anymore. Last month, twelve people come to the meeting, which was more then we expected. Their will be tea and biscuits, and the meeting end at 8 p.m.

How we judged it

An error counts as fixed when the tool flags it and its suggestion gives the right form (the list is in the steps).

Pass: 9 or 10 fixed, and no correct word made wrong.

Partial: 6 to 8 fixed, or 9 or 10 with one correct word made wrong.

Fail: 5 or fewer fixed, or two or more correct words made wrong.

Hemingway Editor: Winner

Pass 9 of 10

Plan: Editor Plus (14-day trial) · Web editor (hemingwayapp.com)

9 of 10 fixed; for "dont" it suggested "don't", not "doesn't". No correct word changed.

Hemingway Editor with the book club notice, ten writing issues and the card on "dont"
The "dont" card offers "don't"; the right form is "doesn't".
Hemingway Editor after the ten suggestions were applied to the book club notice
"the library don't provide them" is still wrong.

ProWritingAid

Partial 8 of 10

Plan: Free · Web editor

8 of 10 fixed ("dont" took two steps, to don't and then doesn't); the fixes for "come" and "end" are Premium-only.

ProWritingAid with the book club notice and ten underlines
Every planted error is underlined.
ProWritingAid after accepting the free fixes, with Premium cards on "come" and "end"
"twelve people come" and "the meeting end" stay unchanged on the free plan.

Hemingway checks grammar only on Editor Plus (here its 14-day trial); ProWritingAid ran on its free plan, where two of its fixes are Premium-only. ProWritingAid fixed "dont" in two steps: first "don't", then a second mark offered "doesn't".

Test 4: Rewrite two long sentences in plain English with AI

· MacBook Pro (M1 Pro), macOS 26.6.2, Chrome 155 and 156

The task

Use each tool's AI rewriting feature on the two long FICTIONAL sentences from the first test, one at a time, to make them easier to read without changing the facts:

Members who have not yet picked up their seed packets from the shed next to the greenhouse should collect them before five o'clock on Friday, May 8, because after that time the volunteers need the whole shed for the spring repairs and the new shelves.

If you need a key and you cannot come to the office during its opening hours on a weekday, you can send a message to the garden secretary, who will try to find a time that suits you and meet you at the gate on a weekend morning instead.

How we judged it

The facts: collect the seed packets from the shed by the greenhouse before 5 p.m. on Friday, May 8, as the volunteers need the shed for repairs and new shelves; anyone who cannot reach the office on a weekday can message the garden secretary, who will try to meet them at the gate on a weekend morning.

Pass: both rewrites keep every fact, add nothing, and have a shorter longest sentence than the original.

Partial: one rewrite drops a detail or is not shorter.

Fail: both do, or either adds a fact.

Hemingway Editor

Partial 18 words

Plan: Editor Plus (14-day trial) · Web editor, Simplify it for me

Longest rewritten sentence 18 words (from 45 and 49), but the first rewrite drops where to collect the packets: the shed by the greenhouse.

Hemingway Simplifying sentence dialogs for the two sentences and the result
The first rewrite no longer says the packets are in the shed next to the greenhouse.

ProWritingAid: Winner

Pass 38 words

Plan: Free · Web editor, Rephrase (Standard)

Longest rewritten sentence 38 words (from 45 and 49); both rewrites keep every fact, including the shed beside the greenhouse, and add nothing, but each stays one long sentence.

ProWritingAid Rephrase panel in Standard mode with two rewrites of the first sentence
First suggestion for sentence one: "Members who haven't collected their seed packets from the shed beside..." The whole sentence was selected; the lines then shifted, so the highlight ends early.
ProWritingAid Rephrase panel for the second sentence, with the first sentence already rewritten above
First suggestion for sentence two: "If you require a key but can't visit the office during weekday opening hours..."

Run by the assistant in the owner's Chrome, signed in: Hemingway on its Editor Plus trial on October 23 and ProWritingAid Free on November 1, 2026 (its 10 free Rephrases a day had run out on October 23). ProWritingAid's Rephrase opened in its default Standard mode, and the first suggestion was used for each sentence. Hemingway split each sentence in two (longest 18 words); ProWritingAid kept each as one sentence (37 and 38 words). Both rewrites are shorter than the originals, which is all the length rule asks; Hemingway's first rewrite dropped the shed.

Our verdict

The choice turns on what you write and how much feedback you want.

Hemingway Editor is the simpler tool for clear, plain prose. Its free online editor already scores readability and highlights hard-to-read sentences, passive voice and words with simpler alternatives, and it costs nothing. Plus adds AI rewrites of those sentences, grammar fixes and written feedback for $100 a year with 5,000 AI sentences a month, or $150 with 10,000, and its 14-day trial asks for no credit card. Hemingway also says neither it nor its AI providers train models on your writing. It lists no plagiarism checker, unused AI credits do not roll over, and its security page says it does not yet have SOC 2 or ISO certification.

ProWritingAid goes deeper, and it is built for fiction. A grammar checker and 25+ reports cover pacing, dialogue, sticky sentences and echoes, and it works in Word, Google Docs, Scrivener, three browsers and its own Windows and Mac apps. Premium is $120 a year or $399 for a lifetime license and includes 1 Chapter Critique a day; Premium Pro allows 30 a day for $144 a year. Plagiarism checks and whole-manuscript analyses cost extra.

For nonfiction, start with Hemingway's free editor. For a novel in progress, ProWritingAid is the better investment.

Choose Hemingway Editor if

You write nonfiction, such as blog posts, reports, emails or help articles, and want it shorter and easier to read. Hemingway's free online editor scores readability and highlights dense sentences, passive voice and words with simpler alternatives, and Plus adds AI rewrites, tone changes and unlimited grammar fixes from $100 a year. You can test Plus for 14 days without a credit card, and Hemingway says neither it nor its AI providers train models on your writing.

Choose ProWritingAid if

Your project is a novel or another long manuscript, and you want feedback on more than sentence clarity. ProWritingAid pairs a grammar checker with 25+ reports, among them pacing, dialogue and echoes, and its AI critiques whole chapters: 1 a day on Premium and 30 a day on Premium Pro, at $144 a year. It plugs into Scrivener and Google Docs as well as Word, and lifetime licenses start at $399. The Free plan lets you try the reports on 500 words at a time.

Frequently asked questions

Which is cheaper, Hemingway Editor or ProWritingAid?

It depends on the tier and the billing. Billed yearly, Hemingway Individual 5K (5,000 AI sentences a month) costs $100, against $120 for ProWritingAid Premium, while Individual 10K costs $150, against $144 for Premium Pro. Billed monthly, Hemingway costs $25 or $30 and ProWritingAid $30 or $36. ProWritingAid also sells lifetime licenses: $399 for Premium and $699 for Premium Pro. For teams, Hemingway Team 10K costs $30 per user a month or $150 per user a year, for up to 50 users; ProWritingAid Teams costs $12 per user a month, billed yearly only, for 2 to 100 users. Both have a free tier.

Does Hemingway Editor check grammar and spelling?

Hemingway's own pages disagree. Its help center says you need Editor Plus to see grammar, spelling and punctuation highlights, and its pricing page lists unlimited advanced grammar fixes, which use no AI credits, on every Plus plan. Its grammar-checker page, though, advertises a free grammar and spelling checker. The free online editor is built around readability: it scores your text and flags hard-to-read sentences, passive voice and words with simpler alternatives. ProWritingAid's Free plan lists grammar, spelling and punctuation checks, on 500 words at a time, along with 2 runs a day of each report.

Which is better for writing a novel?

ProWritingAid. It presents itself as a toolkit for storytellers: its reports cover pacing, dialogue, echoes and sticky sentences, Premium includes 1 Chapter Critique a day and Premium Pro 30, and Story Credits pay for Manuscript, Plot, Character and Marketability analyses and the Virtual Beta Reader; one credit costs $50 at full price, $35 on Premium and $25 on Premium Pro. It also works inside Scrivener. Hemingway focuses on readability: it flags dense sentences and passive voice and, on Plus, rewrites them or gives written feedback on a draft.

Do Hemingway Editor and ProWritingAid use my writing to train AI?

Both say no. Hemingway says neither it nor its AI providers train AI models on your writing, and that it does not store your documents; its security page says it has no SOC 2 or ISO certification yet. ProWritingAid says it never uses your writing to train its AI, and it states SOC 2 compliance, with EU and US hosting options.

Can I try Hemingway Editor Plus or ProWritingAid Premium for free?

Hemingway offers a 14-day trial of Plus with up to 200 AI sentences and no credit card, and the trial ends without charging you; the online editor itself stays free. ProWritingAid offers a Free plan instead of a timed trial: it checks 500 words at a time, with 2 runs of each report, 10 Rephrases and 3 Sparks a day, but no Chapter Critique. Its 3-day money-back guarantee covers yearly and lifetime plans; monthly plans are not refundable.
