WriteSonic’s estimated annual revenue is $1.67 million, and WordTune's is $3.17 million, with both seeing similar traffic (around 2-2.3 million visits).

Key Takeaway
While Grammarly leads in terms of revenue and traffic, other players like QuillBot, WriteSonic, WordTune, and blaze.today show varying levels of user engagement and revenue generation.

Opportunities
The current market tends to favor a one-size-fits-all approach, with no significant niche players addressing specific writing needs. While general-purpose tools like Grammarly are highly effective, they may not excel at more specialized tasks, such as technical writing, where a targeted tool could perform better.
There’s also untapped potential for more flexible solutions that accelerate the writing process by allowing users to define templates tailored to their specific needs. For example, newsletters and reports often follow a consistent structure but use different content and data. A tool that enables easy customization and automation of such templates could greatly enhance productivity for repetitive tasks.
