Grammarly

Pick Grammarly if the writing happens inside the browser and you want a quality layer that never asks you to switch tabs. No other tool catches grammar, tone, and rewrite opportunities inline across 1M+ app/site integrations with the same latency.

Skip it if the job is zero-to-one drafting. Grammarly’s inline writing agents are useful for local rewrites and feedback, but they are not a substitute for Claude or ChatGPT on long-form content. Technical writers and developers also see aggressive false positives on code and jargon.

Who pays which tier: Free for casual users who can live with 100 AI prompts, Pro for individuals and teams up to 149 seats that need 2,000 prompts and team writing features, Superhuman Business when Mail/Coda/Go suite value matters, and Enterprise for larger or more controlled deployments needing SSO, data loss prevention, BYOK, admin, and security controls.

Pricing, plan, and enterprise-control data points above were re-verified against official Grammarly and Superhuman documentation on 2026-06-26. See Sources.

• Inline rewrites hit a coherence ceiling. Grammarly works well inside a paragraph. Drift and generic phrasing show up past 1,000 words, where Claude and ChatGPT produce tighter output.
• False positives in technical contexts. Flags valid code, domain jargon, and proper nouns as errors. Dev tools, API docs, and scientific writing need frequent dismissals.
• No developer API. Teams that want Grammarly-quality checks embedded in internal apps or proprietary editors have no supported path.
• Cloud processing only. All text routes through Grammarly servers for analysis. Regulated orgs that need on-premise processing default to Enterprise data controls or avoid the product.
• Tone detection drifts on short text. Single sentences and bullet points surface misleading tone signals. The feature assumes a paragraph of context.
• Old Business plan assumptions are stale. Grammarly support now says Pro replaces Business, so teams should re-check seat, admin, and procurement requirements before renewing.
• Superhuman Business is a different buying job. It costs more than Grammarly Pro because it bundles Mail, Coda, and Go. Do not treat it as the old Grammarly Business plan.
• Suite consolidation is not automatic. Grammarly support says existing subscriptions do not automatically receive the Superhuman suite and separate subscriptions cannot currently be consolidated into one suite price.
• Plans page can be locale-sensitive. AiPedia uses Grammarly support pricing as the anchor here because the public plans page can show different currency or regional plan labels.
• Expert Review damaged trust. WIRED reported that Superhuman decided to disable the Expert Review feature amid backlash and a class-action complaint. Buyers who care about author likeness, consent, or AI governance should ask what controls now govern expert/persona-style features.
• Strategic uncertainty during the Superhuman suite pivot. The roadmap is expanding beyond pure grammar. Core users should track whether writing-assistant investment stays level as Superhuman Go, Coda, and Mail features ship.

No individual human wrote this review. Scoring follows the four-dimension rubric at /about/scoring/ (Utility x Value x Moat x Longevity, unweighted average). Last verified 2026-06-24 against Grammarly Pro, Grammarly support pricing docs, Superhuman plans, Superhuman Grammarly, Superhuman suite support, Grammarly Business, Grammarly Trust Center, Grammarly affiliates, Superhuman’s GPTZero acquisition announcement, and WIRED’s Expert Review reporting.

Is Grammarly free? Yes. The free tier covers core writing help and 100 AI prompts. Pro unlocks 2,000 AI prompts, advanced writing, rewrites, tone, and team features. Grammarly support lists Pro at $30/member/month, $60/member/quarter, or $144/member/year (Grammarly support).

Is Grammarly Pro worth it vs the free tier? Yes for daily English writers. Pro’s tone suggestions, full-sentence rewrites, advanced writing features, and team controls cover professional polish the free tier does not. Infrequent users may get enough from free.

What changed with Superhuman? Grammarly is now part of the Superhuman suite alongside Superhuman Go, Coda, and Superhuman Mail. Grammarly support says standalone Grammarly remains available for customers who prefer it. Superhuman also announced a June 2026 agreement to acquire GPTZero, so buyers should expect AI-authenticity and writing-integrity features to matter more in the roadmap.

What is the difference between Grammarly Pro and Superhuman Business? Grammarly Pro is the writing-first plan for individuals and teams up to 149 seats. Superhuman Business is the broader suite plan that adds Superhuman Mail, Coda, and Go workflow value, so buy it only if those products matter.

Grammarly vs ChatGPT or Claude for writing? Grammarly checks and polishes text inline across the browser. ChatGPT and Claude draft and rewrite at higher quality but require copy-paste out of the source app. Most professional writers run both: Grammarly inline, a chat LLM for drafting and long-form rewrites.

Does Grammarly have a developer API? No public general-purpose writing API for buyers. Grammarly is primarily delivered through apps, extensions, and enterprise software.
