Use Cases and Deployment Scope

I use Grammarly daily to enhance my writing for internal emails, marketing email copywriting, and website copy.

The business problems Grammarly addresses are uniform tone for customer-facing copywriting, elimination of writing errors, and having a custom library of words unique to our business.

Pretty much anytime I write, I use Grammarly's suggestions to improve my writing and correct my mistakes.

Pros

Fix writing errors
Suggest better words and phrasing
Easy to use

Cons

Sometimes the widget gets in the way
If I don't have access to a feature, stop suggesting it as a blurred suggestion

Likelihood to Recommend

If you write at all, use Grammarly. It's very easy to use, highly accurate, and greatly improves your writing. Whether it's getting a message across to your manager, team, or external business partners, Grammarly makes sure you don't have to worry about your writing.

It is good at its core function, which is spell check and grammar check/optimization. The AI is ok but not great compared to ChatGPT and Claude.

My mixed experience with Grammarly Business

Rating: 6 out of 10

June 3, 2025

Use Cases and Deployment Scope

We use it for writing emailer contect, product roadmaps, marketing messaging communications, video scripts, newsletters, landing pages content etc. I am part of the marketing team and we utilize it for writing and framing both internal and external content. Grammarly is used across Marketing, finance, legal and other ancillary teams.

Pros

Identifying wrong spelling, or english language spelling as per the country language. For example while writing an email to Americans, we might use the spelling color, rather than colour to give more personalisation.
Detecting AI langauge and making communications more authentic.
Ease of passing access to the account across team members.

Cons

UI is very annoying, the hovering cloud of shut down button can be avoided.
Very relentless in highlighting wrong grammar,the red highlights gets annoying on screen while typing.
Instead of real time checking, i would prefer all at once after writing my piece.

Likelihood to Recommend

1. When writing a very important email to internal or external stakeholders.
2. When creating long form marketing content.
3. When writing social media captions.
4. Can be used to identify AI language.
5. To find region specific colloquial terms.
6. Less appropriate for writing low stakes internal emails, or internal chat messaging.

June 2, 2025

Use Cases and Deployment Scope

We use Grammarly likely the same way many other businesses use it: as a tool to guide our language usage and make our communications crisp, clear and concise. The scope is largely any written communication, including email, Slack, and knowledge base articles/customer communications. It doesn't address business problems directly, per se, but it offers fine guidance.

Pros

Reduces word count for clearer sentences
Good diction advice
Filling in missing punctuation

Cons

The location of the overlay tool can be disruptive and hide text

Likelihood to Recommend

Grammarly seems well-suited for basically any written communication, especially for folks who struggle with the written word. Myself, I don't think I struggle at all, but it still manages to offer improvements on my messages, and I do find it helpful here and there.
