A side-by-side breakdown to help you pick the right tool for your workflow.
Review Score assesses product quality; Fit Score is specific to a use case. Limited reviews do not establish overall product quality. How reviews work.
Catch grammar and clarity issues as you write, then let built-in AI agents draft, rewrite, and complete tasks across your apps. Grammarly's parent company rebranded to Superhuman in October 2025.
Score the readability of your writing and flag wordy sentences, passive voice, and complex words, with an optional AI-assisted Plus tier for grammar fixes and rewrites.
Catalog updated: August 2026
Grammarly and Hemingway App both compete in Writing, overlapping most directly on writing.
Choose Grammarly if…
Best for catching grammar and clarity issues in real time as you write anywhere online, and its edge is built-in AI agents now draft and rewrite across your apps, not just proofread. The baseline writing check most people should already have running. Lean toward Hemingway App instead if a grade-level readability score that shows at a glance who can actually follow your writing matters more for your use case.
Choose Hemingway App if…
Best for writers who need to know exactly which sentences are hard to read, not just where the grammar is wrong, and its edge is a grade-level readability score that shows at a glance who can actually follow your writing. The classic/free editor is a clarity checker, not a grammar checker: it flags the problem sentence but leaves the rewrite to you, unless you're on Editor Plus, which does offer fixes and rewrites. Lean toward Grammarly instead if built-in AI agents now draft and rewrite across your apps, not just proofread matters more for your use case.
