For context, Coda's last valuation was $1.4B in July 2021 and Grammarly's was $13B in November 2021. Grammarly's revenue is likely taking a hit with the rise of LLMs and they were always at risk of being a feature by not owning the document editor itself. An all-in-one approach to compete with Notion (and Google Docs, Confluence, Sharepoint, etc) makes sense, but time will tell if this merger works.
