Why we recommend it

Grammarly is the most widely adopted AI writing assistant and a fixture on best-AI-content-tool lists, ensuring marketing content is clear, error-free, and on-brand. It complements generative tools by acting as the editing layer across email, social, docs, and the web, with a usable free tier.

Our take

From our research, Grammarly's standout is breadth of reach — one consistent writing layer across Google Docs, Microsoft Word/Outlook, Gmail, Slack, and many other apps, so polishing and tone/brand consistency happen in place. The tradeoff to weigh: the product is mid-transition under the new Superhuman Platform parent (legacy Premium is folding into Pro), and the most proactive 'works everywhere' AI plus unlimited generative prompts are gated to the Contact-Sales Enterprise tier delivered via Superhuman Go.
