Grammarly
Real-time grammar, spelling, and tone checks everywhere you write.
At a glance
Anyone whose job depends on email, docs, or messages reading well
Our take
Grammarly is the safety net most professional writers have running in the background whether they admit it or not. The free version handles 90% of typos and obvious mistakes. The paid version adds tone detection, rewrite suggestions, and Grammarly’s AI assistant — useful if you write a lot of client-facing email or marketing copy. For published writing, you still need a human editor. For the daily firehose of Slack messages and email, it’s a no-brainer.
