Start with a brief, not a blank request
Before asking an AI to write, note the reader, the one action you want them to take, your source facts, and what must stay unchanged. For an email, this could be a customer who needs to choose a meeting time. Give the actual options and timezone; never ask the model to fill those facts from imagination.
Draft for meaning first
Choose a focused template from the writing collection. Add your facts and audience. Read the result against the brief before polishing sentences: does it answer the question, preserve the facts, and make the next step clear? A fluent paragraph can still contain an invented promise. Remove unsupported claims before running any style check.
Separate correction from preference
Use the proofreading template to request two lists: objective errors and optional style changes. Review those separately. A spelling error usually needs correction; a shorter sentence may be a preference. Keep intentional voice, dialect, quotations, names, and specialist terminology intact. Ask why a suggested change helps this particular reader.
Where Grammarly fits
Grammarly is an optional writing tool to consider for a further editing pass. Its official site describes grammar checking and tone-related features. Check the current product and plan details before choosing it; availability can change. This is a workflow suggestion, not a hands-on product benchmark or a promise that every suggestion is correct. A second tool can flag wording, but it cannot establish the truth of your claims.
A worked editorial example
Illustrative input: “We can deliver Friday if you approve the draft by Tuesday.” An unsafe rewrite would be “We will deliver Friday,” because it removes the condition. A useful final check asks whether dates, amounts, dependencies, and commitments still match the source. This example is written to illustrate the method; it is not a recorded output from Grammarly or any model.
Make the final check yours
Read the draft aloud. Confirm names, dates, numbers, links, quotations, and promises. For confidential work, check your organisation’s rules before pasting text into an external service. Save the original alongside the revision so you can compare meaning. The aim is a clear, accurate message you can stand behind—not accepting every automated suggestion.
