Can an agent replace Grammarly?

I want to cancel Grammarly. It currently does: Grammar, spelling and tone checking across everything you type. Take over this work: - Copywriting — HALF. Half. An agent generates twenty competent variations faster than a copywriter writes one, which is genuinely useful for testing. Choosing the one that is actually right still needs someone with taste and context. - Content writing — HALF. Half. An agent gets you a structurally sound draft in minutes and will never get you a piece worth sharing on its own. The gap is not writing ability — it is that it has nothing of its own to say. - Documentation — YES. Yes, and it fixes the real problem, which was never writing documentation but keeping it true. An agent regenerates docs as the code changes, which no human team has ever sustainably managed. Do not take over: - The always-on habit, which is a real behavioural advantage These stay with me across all of it: - Positioning - The final call - Anything that makes a promise you have to keep - The argument - Anything drawn from your own experience - Final edit and the decision to publish - Architectural rationale - Deciding what deserves documenting - The overall narrative Before we start, tell me: which of these you cannot do with the access I can actually give you, and what would break if this ran unattended for a month. — brief built at cananagentdo.com/grammarly
