Dock vs Grammarly
Grammarly polishes the words you already wrote. Dock helps you write them, cite real sources, and work from anywhere you type. A fair comparison, including where Grammarly is the better pick.
Grammarly and Dock get put side by side a lot, and the comparison is a little unfair to both. Grammarly is a writing assistant that watches what you type and fixes it: grammar, spelling, clarity, tone, and a layer of generative AI on top. Dock is a writing editor: a place to draft a document, cite real sources, and ship it. One cleans your prose. The other helps you produce it.
They even cost the same. Grammarly Pro is $12 a month billed annually, which is $144 a year. Dock Unlimited is also $144 a year. So this is not a price argument. It is a question of what the same money should buy you.
If your writing is already drafted and you want it to read better, Grammarly is excellent and you should probably keep it. If you are producing the writing itself, especially anything that needs citations, Dock is built for that and Grammarly is not.

| Paid price | $12/mo billed annually ($144/yr) | $12/mo billed annually ($144/yr) |
Grammarly has spent over a decade on one hard problem: catching mistakes in real time, in any app, without getting in your way. It is very good at it.
- It is everywhere you write, instantly. Email, docs, social, comment boxes. The corrections appear as you type, with no panel to open.
- Its grammar and tone engine is more mature. For pure correctness and tone-shifting on text you already have, it is the benchmark.
- It does not require you to change tools. You keep writing where you write. Grammarly just makes it cleaner.
If that is the whole job, Grammarly wins, and switching to Dock would be a downgrade for that specific task.
Dock is not trying to be a better proofreader. It is trying to be the place the writing happens, which is a different and larger job.
- Citations from real papers. Dock searches an academic index and returns sources with titles, authors, and DOIs you can verify. It formats them in seven styles (APA, MLA, Chicago, Harvard, IEEE, AMA, Vancouver) and switches the whole document between them in one move. Grammarly has nothing here.
- Drafting, not just correcting. Improve, rewrite, expand, shorten, or summarize any passage, with every suggestion staged for you to accept or reject before it touches the page.
- It writes from outside the browser. Drive the same documents from the
agentdockcommand line or an MCP client like Cursor. For people who live in a terminal, this does not exist anywhere in Grammarly. - Real export. Word with tracked changes intact, PDF, Markdown, and HTML, because the document is yours to take with you.
Yes, and many people do. Grammarly runs as a layer across your whole machine; Dock is where you write the serious, cited documents. They do not conflict. If you only want to pay for one and you write research, reports, or anything with a reference list, Dock covers more of the actual work for the same annual price.
Pick Grammarly if your writing is already happening somewhere you like, and you want a tireless editor catching mistakes and adjusting tone across every app you use.
Pick Dock if you are producing documents, you cite sources, or you want an assistant that drafts with you and reaches you in your editor, your browser, and your command line, for the same $144 a year.
