Move your team from ProWritingAid to Grammarly.
Each person gets a short interview, then a personalized step-by-step guide showing exactly where their saved work, prompts, and projects land in Grammarly — and the few things that need a manual step, walked through. You send one invite; nobody becomes the help desk, and nothing in ProWritingAid is changed or cancelled. Want to see where you’re paying for both first? Run the free audit.
Both tools provide inline grammar, spelling, punctuation, and style suggestions while writing. To migrate from Grammarly to ProWritingAid: install the ProWritingAid browser extension (Chrome/Firefox/Edge) or the Word/Google Docs add-in to replace the Grammarly extension — they surface corrections in the same documents. Disable or uninstall Grammarly to avoid conflicting overlays. ProWritingAid's Realtime Checker fires suggestions inline just as Grammarly does; the free tier caps checks at 500 words per document, so Premium ($10/month annual) is needed for full-length documents. Going the other way (ProWritingAid → Grammarly): install the Grammarly extension and add-in, then remove ProWritingAid's. Grammarly's free tier offers grammar and spelling on unlimited document length with no word cap.
- Warning: ProWritingAid Free is capped at 500 words per document and 2 report runs per day; Grammarly Free has no documented word cap on grammar checking.
- Warning: ProWritingAid works in Scrivener (a key differentiator for fiction writers); Grammarly does not support Scrivener.
- Warning: Running both extensions simultaneously can cause suggestion conflicts and slow page rendering — uninstall one before activating the other.
Both tools offer on-demand plagiarism scanning within their editors. To migrate from Grammarly to ProWritingAid: paste or import the document into the ProWritingAid web editor, then run the Plagiarism Report from the reports panel — it compares against web pages and academic databases and returns flagged passages with source attribution. Grammarly's plagiarism check is also on-demand (via the agents panel in Grammarly docs); the workflow is functionally equivalent. Going the other way (ProWritingAid → Grammarly): paste the document into a Grammarly doc or open it in Word/Google Docs with the Grammarly extension active, then trigger the Plagiarism check under the agents panel. Grammarly's database covers 16 billion+ web pages plus ProQuest academic papers, which is more precisely documented than ProWritingAid's public spec.
- Warning: Both plagiarism checkers require a paid plan — Grammarly Pro/Plus/Business/Enterprise/Education; ProWritingAid Premium or Premium Pro.
- Warning: Grammarly's plagiarism feature is not available on mobile; ProWritingAid's is available only inside the web editor (no browser extension or Word add-in check).
- Warning: ProWritingAid's credit/quota system for plagiarism checks is not fully documented publicly — verify consumption limits before switching for high-volume use.
- Warning: Grammarly explicitly documents 16 billion+ web pages + ProQuest; ProWritingAid does not publish an equivalent database-size figure.
Both tools integrate with Microsoft Word, Google Docs, browser-based text fields (via Chrome/Firefox/Edge extension), and web editors. Migrating from Grammarly to ProWritingAid: (1) Uninstall the Grammarly browser extension from your browser's extension manager; (2) Install the ProWritingAid browser extension — it will activate in Google Docs, Gmail, Notion, Discord, and Apple Notes automatically; (3) In Microsoft Word, remove the Grammarly Word add-in (Insert > Add-ins > Manage) and install the ProWritingAid add-in from the Microsoft Office store; (4) If using Scrivener, install the ProWritingAid Scrivener integration (Windows and Mac), which has no Grammarly equivalent. Going the other way (ProWritingAid → Grammarly): remove the ProWritingAid extension and Word add-in; install Grammarly's browser extension and the Grammarly for Microsoft Office add-in; re-connect Grammarly's desktop app if you use Word on Windows or Mac for the deeper inline experience.
- Warning: Grammarly supports Outlook, Slack, Figma, FigJam, Salesforce, Zendesk, and 1 million+ apps via its desktop overlay; ProWritingAid does not have equivalent coverage for these tools.
- Warning: ProWritingAid is the only option of the two with a Scrivener add-in — fiction writers on Scrivener cannot replicate this with Grammarly.
- Warning: Grammarly mobile keyboards are available for iOS and Android; ProWritingAid has no mobile keyboard app.
- Warning: All ProWritingAid integrations are included on Free, Premium, and Premium Pro plans with no per-integration upsell; Grammarly's integrations are also plan-agnostic, but some features within them (e.g. style guides in the Word add-in) require Business or Enterprise plans.
Grammarly's tone detection gives real-time tone labels (confident, formal, friendly, etc.) with one-click adjustments on Pro+; ProWritingAid's 25+ writing reports give deeper post-draft analysis covering passive voice, overused words, clichés, readability, sentence structure, transitions, and more. The two serve overlapping but distinct use-cases: Grammarly is better for in-flow tone nudges while composing; ProWritingAid is better for a structured editing pass after a draft is complete. Migrating a workflow from Grammarly tone feedback to ProWritingAid: finish the draft in any editor, paste it into the ProWritingAid web editor or open the add-in, then run the Style Report and Readability Report — these surface the stylistic signals that Grammarly's tone labels point to. Migrating from ProWritingAid reports to Grammarly: paste the edited document into Grammarly docs or open in Word/Google Docs with the extension; use the tone display (free) and tone adjustments (Pro) to refine the register in real time. There is no equivalent in ProWritingAid to Grammarly's Brand Tones team governance feature.
- Warning: ProWritingAid Free limits users to 2 report runs per report per day on documents up to 500 words — Premium is required for full-document style reports.
- Warning: Grammarly tone adjustment (rewriting to a new register) requires Pro or higher; the free tier shows detected tone labels only.
- Warning: ProWritingAid has no team-level style-guide enforcement equivalent to Grammarly's Business/Enterprise Brand Tones feature — teams with brand-consistency requirements should note this gap.
Both tools let writers select text and apply AI-assisted rewrites, though with different framing. Grammarly frames rewrites around clarity and conciseness (sentence- and paragraph-level suggestions appear inline); ProWritingAid frames them as Rephrase options (formality, length, fluency, or sensory enhancement) or Sparks Edits (readability, tense/person changes). To migrate from Grammarly to ProWritingAid: in the ProWritingAid web editor or supported add-in, select the passage, click Rephrase, then choose the style variant closest to your intent (e.g. 'Readability' maps to Grammarly's clarity suggestions; 'Formality' maps to tone-targeted rewrites). Going the other way: in Grammarly docs or the browser-extension overlay, accept full-sentence or paragraph rewrites from the inline suggestion cards — no separate mode needed. Note that Grammarly's free tier includes sentence-level suggestions but gates full-paragraph rewrites to Pro; ProWritingAid Free caps rephrases at 10 per day.
- Warning: Grammarly full-paragraph rewrites require Pro; ProWritingAid free plan is capped at 10 rephrases per day — Premium is needed for unlimited use.
- Warning: ProWritingAid's Sparks Edits quota differs by plan (5 Sparks/day on Premium, 50/day on Premium Pro); heavy users should plan accordingly.
- Warning: Grammarly rewrites are surfaced contextually as inline suggestion cards; ProWritingAid requires explicit selection and a click — there is no auto-suggest equivalent for rephrasing.
