A Grammarly alternative for your Windows writing.
Check selected text, review the changes and keep control of your writing. Dictation is included in the same app.
Windows 10 and 11. One-time licence for 3 devices. Connect your own AI provider; usage charges are separate.
Buy ProofFlick for $39.99 at launch (regular price $99.99). Read the setup guide.
Correct your writing when you choose
Select text, trigger ProofFlick and review the corrected version. Proof only keeps edits focused on corrections; Polish, Rework and Shorten offer other ways to work with your draft. Writing profiles let you set preferences for different kinds of writing.
ProofFlick also includes dictation, so you can speak a draft before checking it. It uses your own provider account rather than including a managed AI subscription.
Compare the whole cost
Grammarly Pro's standard US annual price is $144 annually or $30 when paid monthly. ProofFlick is $39.99 once at launch, normally $99.99 once, plus any AI-provider usage. Regional prices, discounts and taxes can change the comparison. Official Grammarly pricing, checked 17 September 2026.
A different workflow, not every Grammarly feature
ProofFlick is a Windows app for selected-text proofreading and dictation. Do not assume it reproduces Grammarly's always-on writing assistance, plagiarism tools, citation features, mobile support or team administration. If those features matter to you, include them in your decision. See Grammarly's own feature list.
Who it suits
- People writing emails, briefs and everyday work on Windows.
- People who want to review edits and preserve their own voice.
- People who prefer a one-time app purchase and provider choice.
Your first comparison
Use a short piece of your own writing. Run Proof only, review every change and use the result in your intended application. Then try dictation and a writing profile. Judge the actual result and the setup involved before changing an existing subscription.
Application support varies. See current compatibility notes, including the reported Word Replace issue in version 1.2.0. Compare the features you actually use before switching.
