Grammarly Review

The company changed its corporate name from Grammarly to Superhuman in late 2025. That's not a refresh — it's a thesis. Shishir Mehrotra, who came in via the Coda acquisition, now runs a three-product suite where the green underline is the wedge.

$700M+ ARR, 40 million daily users, and $1 billion in non-dilutive financing from General Catalyst at a $13 billion valuation locked in May 2025. Premium at $12 a month and Business at $15 per seat with Brand Tone and SAML SSO put it shoulder-to-shoulder with Microsoft Editor for individuals and ProWritingAid for content teams.

But the rebrand is the risk. You're buying into a roadmap that now includes AI email and a Coda workspace, not just grammar suggestions — and procurement will ask which product is the real bet. Run Business with one department for 90 days before standardizing.

Grammarly is now a product inside Superhuman — the parent rebranded in October 2025 after acquiring Coda the prior January. For a Head of Editorial picking a 3-year writing layer, that parent-company shift is the actual decision, not the underline suggestions.

The editorial substance holds. Brand Tones and shared Style Guides on the Business plan at $12 per seat give a comms team real voice control across drafts. Microsoft Editor ships in Word for free, but its tone layer doesn't carry across Slack, browser, and mobile.

But the catch is the 150-seat threshold. Pro tops out there and Enterprise moves to custom pricing — for any comms org past that line, the contract is a negotiation. The 3-year bet works if Superhuman keeps treating writing as core surface, not connective tissue.

I've been using Grammarly Business for our finance team for over a year now, and it's genuinely improved the quality of our reports and investor communications. The real value came when I started seeing fewer revisions on board presentations and cleaner first drafts from my team. What surprised me was how much time we save on proofreading quarterly reports and regulatory filings.

The pricing structure is straightforward but inflexible. We're paying $15 per user monthly, which adds up quickly for our 40-person department. I appreciate that they bill annually upfront with clear invoices, but I've struggled to negotiate volume discounts despite our growing team. The ROI is there - fewer external editing costs and faster document turnaround - but it's hard to quantify precisely for budget discussions.

Goals are where Grammarly diverges from a spell-checker. Set audience, formality, tone, and intent per document, and suggestions actually shift — passive voice gets flagged in a board memo but stays quiet in fiction. Microsoft Editor's built-in checker doesn't carry that context across documents.

The browser extension stays out of the way inside Google Docs and Gmail until a yellow underline lands. Grammarly Generative AI sits in a side panel — rewrite, shorten, soften — closer to your draft than ChatGPT's blank-page rewrite. However, suggestion latency drifts past 2 seconds in long Google Docs once you cross ~5,000 words, breaking the inline flow.

Pro is $12/month annual, $30 monthly — the gap punishes anyone testing it. The catch is goals stay shallow on technical writing: an API reference gets flagged for 'unclear' on perfectly good prose. Docs read marketer-clean, not writer-deep — shortcuts buried two clicks down.

I've been using Grammarly Premium daily for over a year, and it's transformed how I approach writing. The browser extension seamlessly checks everything from emails to social posts, catching not just typos but awkward phrasing and clarity issues. What surprised me most was how it improved my writing over time - I make fewer mistakes now because I've learned from its suggestions.

The tone detection feature has saved me from sending emails that sounded harsher than intended. However, it sometimes flags perfectly good sentences as unclear, especially with technical writing. The mobile keyboard is decent but occasionally laggy. Overall, it's become indispensable - I feel naked writing without that green checkmark.

I was a paying Grammarly user who genuinely relied on it for client communications and proposals. The basic grammar catching worked, but everything else slowly fell apart. The browser extension would randomly stop working mid-email, forcing me to copy-paste into their web app. Their 'tone detection' became increasingly aggressive, flagging normal business language as 'too harsh' while missing actual clarity issues.

The final straw was when they broke Google Docs integration for three weeks straight. Support just kept sending the same troubleshooting steps. Meanwhile, they kept pushing their new AI features I didn't want instead of fixing core functionality. I switched to ProWritingAid and haven't looked back.
