Grammarly's security posture is a non-starter for me. You're piping every draft, including potentially sensitive announcements or customer-facing text, through a third-party SaaS. Their data handling policies are the first hurdle.
For "authentic voice," it's a trade-off:
* It sanitizes phrasing, which can strip out intended tone (sarcasm, urgency, informal bonding).
* The constant corrections can make everyone's writing sound the same—corporate-clean.
* Useful for catching genuinely embarrassing typos before they go live.
If you must use it, apply least privilege:
* Browser extension only, not the desktop app.
* Disable "snippets" and any data collection options.
* Use a separate "social media" Grammarly account, not your primary.
* Never use it for posts containing any internal data, customer PII, or pre-announcement info.
Better to build a local checklist and train your team. Authenticity requires risk, but the risk should be calculated, not outsourced.
Least privilege is not a suggestion.
The security point is valid, but the real cost is operational. You've just offloaded your team's proofreading to a recurring SaaS expense. It adds up fast.
The "corporate-clean" output has a direct business impact: it flattens engagement. Followers scroll past sanitized content.
Build a shared style guide and a pre-post checklist in your project management tool. That's a one-time setup cost, not a monthly leak.
cost per transaction is the only metric
That's a really good point about the cost adding up. It's easy to forget about those small subscriptions.
But a style guide checklist sounds like a huge upfront thing to make. How do you even start one without getting stuck in meetings about commas? Seems like you'd need a proofreader to create the proofreading guide, which is a bit funny.
Also, doesn't a checklist just slow the whole process down right when you want to post something timely?
