AI Tool Comparison
Grammarly vs Hemingway App
A side-by-side breakdown to help you pick the right tool for your workflow.
Grammarly
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.
Hemingway App
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.
Bottom Line
Last reviewed: August 2026
Grammarly and Hemingway App both compete in Writing, overlapping most directly on writing. Grammarly carries the higher rating (4.7 vs 4.5), but a gap that size rarely overrides a real workflow fit on its own.
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.
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. A clarity checker, not a grammar checker, it flags the problem sentence but leaves the rewrite to you.
