Verdict
Keep paying
The writing help is replaceable. The keyboard is not, and the keyboard is what people describe paying for.

The web consensus
Review sites land on "worth it if you write a lot, overpriced if you do not". The free tier is repeatedly called genuinely useful. The one thing every positive review names is the same: it works everywhere without copy-and-paste.

r/Grammarly — The Only Reason I Paid For Premium ▲18
Declining suggestion quality, removed features and cheaper alternatives made renewal unjustifiable.
r/LawSchool — Is Grammarly Premium Worth It? ▲6
Generally not worth paying for — the free tier and other AI tools cover most needs.
r/CarletonU — Is grammarly worth it? ▲5
Keep the free version. Premium was costly and its suggestions were sometimes wrong.
r/Grammarly — Is Grammarly Premium worth it? ▲5
Split: some praised the extra corrections, others cancelled over distracting suggestions.
r/Grammarly — is premium subscription worthy? ▲5
Too expensive unless you need it heavily for work or school.
