Part 2- Tools for Text-Based AI: Grammarly
3. Grammarly in Action – Real Use Case Workflow with Examples
In this chapter, we will explore how Grammarly works in real-time across different use cases. You’ll understand how Grammarly detects and corrects issues ranging from grammar and spelling to tone and clarity. Each section includes a workflow example to demonstrate Grammarly’s layered correction system in practice.
3.1 Use Case 1: Correcting a Business Email
User Input:
“Hope your doing well. I wanted to know if their’s any update on the meeting schedule?”
Step-by-Step Grammarly Workflow:
- Text Input Detection
Grammarly activates when text is typed into an email body. - Tokenization and POS Tagging
- Identifies "your" as a possessive pronoun (should be "you’re").
- Flags “their’s” as incorrect (intended: “there’s”).
- Grammar and Spelling Check
- Corrects “your” → “you’re” (subject-verb contraction)
- Corrects “their’s” → “there’s” (contraction of “there is”)
- Punctuation Adjustment
- Flags the lack of a proper closing punctuation mark (question mark is correctly used).
- Suggests a comma after the opening phrase: “Hope you’re doing well,”
- Clarity and Formality
- Suggests rephrasing:
“I wanted to know if there’s any update on the meeting schedule?”
→ “Could you please share any updates on the meeting schedule?”
- Suggests rephrasing:
Final Suggestion Output:
“Hope you’re doing well,
Could you please share any updates on the meeting schedule?”
3.2 Use Case 2: Improving an Academic Paragraph
User Input:
“The experiment was done to check the influence of light on the plant’s growth. Results shows that more light makes plants grow faster.”
Step-by-Step Grammarly Workflow:
- Syntactic Analysis
- Flags passive voice in “was done”
- Identifies verb-subject disagreement in “Results shows”
- Grammar and Readability Check
- Suggests changing “was done” → “was conducted” for formality
- Corrects “shows” → “show”
- Style and Engagement Improvement
- Suggests replacing “check” with “examine” or “investigate”
- Suggests removing “makes” → “promotes” for academic tone
Final Suggestion Output:
“The experiment was conducted to investigate the influence of light on plant growth. Results show that increased light exposure promotes faster plant growth.”
3.3 Use Case 3: Social Media Caption Enhancement

4. Customization and Grammarly Goals
One of Grammarly’s strongest features is its ability to adapt suggestions based on what the user is trying to achieve. Whether you're writing a professional email, a casual social media post, or an academic paper, Grammarly allows you to customize its behavior through writing goals. This chapter explains how customization works and how to set Grammarly Goals to get personalized writing feedback.
4.1 What Are Grammarly Goals?
Grammarly Goals are user-defined settings that help the tool tailor its suggestions based on your intent, audience, style, and more. Instead of offering one-size-fits-all suggestions, Grammarly adjusts its feedback based on your selected goals.
4.2 Types of Customizable Goals
When starting a new document in Grammarly, you’re often prompted to choose from the following categories:
1. Audience
- Options: General, Knowledgeable, Expert
- Purpose: Determines how complex or simple your language should be.
- Example:
- If you select "General", Grammarly recommends simpler vocabulary and more explanation.
- If you choose "Expert", it assumes your audience understands jargon.
2. Formality
- Options: Informal, Neutral, Formal
- Purpose: Adjusts tone and sentence structure.
- Example:
- Informal: “Can you help me out?”
- Formal: “Could you please assist me?”
3. Domain (Writing Type)
- Options: Academic, Business, General, Email, Creative, Casual
- Purpose: Tailors feedback to the writing’s purpose.
- Example:
- In an Academic document, it discourages contractions and favors objective language.
- In a Creative piece, it allows more flexible sentence structures and expressive word choices.
4. Tone
- Options: Confident, Joyful, Optimistic, Friendly, Urgent, Analytical, etc.
- Purpose: Suggests words and sentence styles to match the emotional intent.
- Example:
- A friendly tone may suggest using “Hi there!” over “Dear Sir/Madam.”
- An urgent tone might favor shorter, action-oriented sentences.
5. Intent
- Options: Inform, Describe, Convince, Tell a Story
- Purpose: Helps Grammarly adjust clarity and structure based on communication goals.
- Example:
- For "Convince", it focuses on logical flow and persuasive wording.
- For "Describe", it may suggest adding sensory details.
4.3 How to Set Grammarly Goals (Step-by-Step)

Step 4: Start Writing

4.4 Example Scenarios with Goal Customization
Scenario 1: Business Email

4.5 Why Customization Matters
Without Custom Goals | With Custom Goals |
---|---|
Generic suggestions | Personalized feedback |
One writing style for all contexts | Adapts to academic, business, or creative writing |
May overlook tone or formality | Suggests based on your audience and intent |
Custom goals help Grammarly behave more like a smart editor rather than just a grammar checker. It becomes an intelligent writing assistant tailored to your objectives.
4.6 Limitations of Customization
- Not all tones work equally well for every domain (e.g., "joyful" in an academic setting may cause conflicting suggestions)
- Limited options in free version
- Some combinations may produce overly cautious suggestions, especially in formal + expert settings
