The Good and the Bad
What we like
- +Works everywhere -- browser extension, desktop app, mobile keyboard, Google Docs, Office
- +Grammar and spelling correction is the best available, period
- +Tone and clarity suggestions genuinely improve writing

What could be better
- −AI writing capabilities are basic compared to Claude or ChatGPT
- −Premium feels necessary -- the free tier misses too many suggestions
- −Can be overly aggressive with suggestions, making writing feel generic
- −Desktop app is heavy and can slow down your system

Known Issues
- PARENT-COMPANY LAUNCH (2026-07-08): Superhuman (the company formerly known as Grammarly) launched **Superhuman Docs** -- a collaborative document platform built on the acquired Coda technology, merging writing, AI, and structured data. Features: AI-drafting from prompts, structured tables + interactive data views, a Docs AI assistant (drafting, table creation, comment resolution, cross-document retrieval), AI Views in private beta (describe a custom interface, the system builds it on live data), Superhuman Databases private beta (up to 1M rows), and an MCP connector linking Docs to ChatGPT, Claude, and Cursor. Early users: Figma, DoorDash, The New York Times. No pricing disclosed at launch. Relevance for Grammarly users: the writing assistant is now one product in a growing Superhuman suite (Mail, Go, Docs, Coda), and suite-level bundling/pricing changes are worth watchingSource: SiliconANGLE (siliconangle.com/2026/07/08/superhuman-launches-docs-merging-writing-ai-data-document-collaboration/) · 2026-07-08
- COMPANY REBRAND (2025-11-05, catalogued late -- our miss): **Grammarly the company renamed itself Superhuman.** The Grammarly writing product keeps its name, but it now sits inside a multi-product AI productivity company: Grammarly (writing), **Coda** (collaborative workspace), **Superhuman Mail** (the email client it acquired), and **Superhuman Go** -- a new proactive AI assistant that launched with agents from partners including Google Workspace, Microsoft Outlook, and Atlassian (Go features were free for all users through 2026-02-01). Vendor framing: 'AI should amplify human capability, not replace it.' Practical read: expect the standalone Grammarly experience to keep converging with the Go assistant and the broader Superhuman suite -- if you only want the grammar net, watch for bundle upsellsSource: Superhuman/Grammarly blog (grammarly.com/blog/company/announcing-company-rebrand-to-superhuman/) · 2025-11
- Browser extension occasionally conflicts with web-based editors (Notion, Confluence), causing formatting issuesSource: Grammarly Community · 2026-03
Best for
Non-native English speakers, professionals who write lots of emails, and anyone who wants a passive grammar net running in the background. It catches things you'd miss.
Not for
Creative writers who have a deliberate style (Grammarly will try to 'fix' it) or anyone who just needs AI content generation (use Claude/ChatGPT).
Our Verdict
Grammarly is less of an AI tool and more of a writing safety net that now has AI features bolted on. It's excellent at what it was built for -- catching errors and improving clarity. The AI rewriting is fine but not why you'd buy it. Think of it as spell-check on steroids, not an AI writer. One structural note: the company behind it renamed itself Superhuman (November 2025) and is assembling a productivity suite around the writing product -- Coda, Superhuman Mail, and the Superhuman Go assistant -- so expect the standalone Grammarly experience to keep drifting toward that bundle.
