I used to dread updating my resume. Formatting, tone, keywords—it all felt like guesswork. And cover letters? Even worse. I’d spend hours trying to sound professional but authentic, formal but not robotic. It always felt like I was writing into a void.
So when I started job hunting again in early 2025, I promised myself I’d try something different: I’d let AI help.
But not just any AI. I needed something accurate, well-formatted, and—most importantly—personalized. That meant ChatGPT wouldn’t cut it on its own. I wanted access to multiple models, so I could experiment and compare tone, structure, and results.
One Platform, Every Major Model
Instead of paying for a separate subscription to ChatGPT, Claude, or Gemini, I found LeemerChat—a €15/month platform that includes GPT-4.1, Claude 3.7 Sonnet, Gemini 2.5 Pro, and LLaMA 4 Scout in a single dashboard. It sounded too good to be true, but I gave it a shot.
Here’s what I managed to create in under three hours:
- A two-page professional resume tailored to product management roles
- A personalized cover letter referencing the hiring manager and company values
- A LinkedIn “About” section that matched the tone and language of tech recruiters
All of it was generated, edited, and finalized using just AI prompts—no templates, no downloads.
Resume Writing with Claude + GPT-4
I started with Claude 3.7 Sonnet. I uploaded my old resume and gave it this prompt:
“Update this resume for a mid-level product manager role at a SaaS company. Focus on results and metrics. Keep the tone professional and ATS-optimized.”
Claude responded with a beautifully structured draft—clean, focused, and heavy on numbers. It even rewrote my job descriptions with measurable outcomes.
Then I switched to GPT-4.1 and gave it the same prompt. Its version had a stronger narrative flow and better use of industry-specific keywords.
I ended up merging the best of both: Claude’s bullet points and GPT-4’s summary sections. Within an hour, I had a resume I would’ve paid a consultant €200+ to write.
Cover Letter? Gemini Pro Nailed the Tone
Next, I pasted in the job description and asked Gemini 2.5 Pro:
“Write a personalized cover letter for this job based on my resume. Keep it concise, persuasive, and human.”
In under 30 seconds, I got a draft that hit every mark: It referenced the job post, highlighted my experience, and even included a clever closer. All I had to do was tweak a few sentences—and the cover letter was done.
Bonus: Cold Emails and LinkedIn Outreach
One unexpected benefit? I also used the AI to write a cold email to a hiring manager. Here’s what I did:
- Asked Claude to draft an initial cold outreach email
- Had GPT-4 rewrite it in a more casual, direct tone
- Let LLaMA Scout shorten it to under 100 words
I sent the final version on LinkedIn and got a response within two hours.
Why AI Beat Every Template I’ve Ever Tried
I’ve used Canva, Zety, and all the resume builder sites before. But they always felt generic. With AI, I could actually iterate. I’d say things like:
- “Make it more conversational”
- “Add a line about leadership”
- “Include keywords from this job posting”
Each model responded in real time—and I could switch between them to compare results.
No template can do that.

For €15/month, LeemerChat gave me the ability to:
- Access all the top AI models
- Generate multiple versions of the same document
- Use natural prompts instead of rigid templates
- Save hours of writing, editing, and formatting
In one afternoon, I created everything I needed for a polished application—and felt more confident hitting “Send” than I ever had before.
