Today, Thairath Online dives deep into how to use ChatGPT and Gemini to architect your perfect resume, from structuring it to creating prompts that make you stand out among applicants.

In-depth guide to using AI to craft a resume that lands the job (2026 edition)

In an era when most companies use ATS (Applicant Tracking System) for initial screening, writing a resume with the correct keywords is crucial. Here are steps you can command AI to do excellently for you.

Step 1: Prepare the materials (The Data Input)

Before instructing AI, you must collect your basic information to prevent AI from "making things up" or generating false data.

• Work history (position, company, duration)
• Measurable achievements (e.g., increased sales by 20%, reduced costs by 15%)
• Job description (JD) for the position you want to apply for

Step 2: Create the secret prompt (The Master Prompt)

Don’t just say "write me a resume" because the result will be too broad. Use the structure Role + Context + Task + Format as follows.

[Copy and customize as needed]

"You are an HR Manager with over 15 years of recruitment experience in the [specify industry, e.g., Tech/Banking] sector. Please write a resume for the position of [specify position] based on my work history below, tailored to the attached job description (JD). Emphasize action verbs and ensure 100% ATS compliance. Group skills professionally."

Step 3: Plan the layout (The Layout Strategy)

AI will help organize content according to 2026 standards as follows:

• Professional Summary: Summarize your profile in 3 powerful lines (instruct AI: "Help summarize my key experience attractively in 3 sentences").
• Experience (focus on results): Use Google's XYZ Formula (What + How measured + How achieved).
• Example: Tell AI "Help improve the phrase 'I managed sales' into formal language with numeric results based on the XYZ formula."
• Skills Matrix: Separate Hard Skills and Soft Skills (AI analyzes the JD to identify required keywords).

Step 4: Use Gemini for in-depth analysis (The Comparison)

Gemini (Google AI) has better access to current data. You can send the JD link from LinkedIn and instruct:

"Please compare my profile with the requirements in this link and tell me which important keywords I’m missing."

Be cautious: don’t let AI work alone.

No matter how smart AI is, "humanity" and "honesty" are the most important.

• Verify accuracy: Never let AI add university or company names you did not actually attend or work for.
• Adjust tone: Ensure the language doesn’t sound too "robotic."
• Consistency: Check spelling and grammar (even though AI is good, small mistakes can make you look unprofessional).

Using ChatGPT and Gemini to write resumes is not cheating but a tool to "communicate" your potential clearly. If you combine this technique with other AI work apps we’ve recommended, your career path in 2026 will surely take off.
