Grammarly
Grammarly in 2026: parent company now named Superhuman, adds AI agent ecosystem (Superhuman Go). Pro plan from $12/month, free plan capped at 100 AI prompts.
About Grammarly
What is Grammarly (2026 update)
Grammarly is an AI writing assistant that checks spelling, grammar, tone, and clarity across browsers, documents, and apps, and can now rewrite full sentences or draft new text outright. It belongs in the writing and editing category, and while the writing product still carries the Grammarly name, its parent company has changed identity in 2026.
What is new in 2026
The biggest 2026 development is a corporate rebrand: Grammarly’s parent company renamed itself Superhuman, bringing Grammarly, the productivity app Coda, and Superhuman Mail under one umbrella alongside a new product called Superhuman Go. Superhuman Go introduces an ecosystem of AI agents that work inside the tools people already use, including partner agents from Box, Gamma, and Wayground added in February 2026, which bring capabilities like enterprise document access and visual content creation directly into the Grammarly browser extension for Chrome and Edge. In March 2026, Superhuman added Grammarly Authorship attribution, which tracks which specific AI agent contributed to a piece of writing, plus admin controls letting schools decide which AI agents students and faculty can access. The underlying Grammarly writing product itself still centers on tone detection, full-sentence rewrites, and a monthly allowance of AI generation prompts.

Who should use it
Grammarly suits anyone who writes professionally in English or other supported languages and wants consistent grammar and tone checking across every app they use, from email to Google Docs to Slack. The Superhuman Go agent ecosystem adds appeal for teams already using tools like Box or Gamma who want those capabilities surfaced inside the same writing workflow. It is a heavier lift for users who only need occasional spell-checking, since the more advanced rewriting and agent features sit behind the paid Pro tier.
Limitations and alternatives
The free plan’s 100 AI prompts per month is a meaningful limit for anyone who wants to draft with AI regularly, and Pro’s price jumps sharply if you do not commit to annual billing ($12 vs $30 per month for the same features). The company-level rebrand to Superhuman may also cause short-term confusion about product naming and account management. Alternatives include ProWritingAid for deeper style and readability analysis aimed at authors, Microsoft Editor for users already inside Word and Outlook, and QuillBot for a paraphrasing-first workflow at a lower price point.
