I Replaced ChatGPT with Gemini CLI for 7 Days – Here’s What Happened

 For the past year, ChatGPT has been my go-to AI assistant—helping me write code, draft emails, and even brainstorm blog ideas. But when Google announced Gemini CLI, a command-line version of their powerful Gemini AI, I was intrigued. Could it replace ChatGPT in my daily workflow?

I decided to switch entirely to Gemini CLI for 7 days and document the experience. Here’s what happened—the good, the bad, and the surprising.

Day 1: Setting Up Gemini CLI

Installation & First Impressions

Unlike ChatGPT’s web-based interface, Gemini CLI runs directly in the terminal. Installation was straightforward:

bash

pip install google-gemini-cli
gemini auth login

Once logged in, I could start querying Gemini just like ChatGPT, but with a minimalist, keyboard-driven approach.

✅ Pros:                                                         

• No distractions (no ads, no fancy UI)

• Super fast responses

• Works offline after initial auth

❌ Cons:

• No built-in chat history (unlike ChatGPT’s persistent threads)

• Requires some command-line familiarity

Verdict: If you love terminals, this is a dream. If not, the learning curve might be steep.

Day 2-3: Writing & Productivity 

Gemini for Content Creation

I tested both AIs on blog writing, email drafting, and SEO optimization
. Here’s how they compared:

Task	ChatGPT (GPT-4)	Gemini CLI (Gemini Pro)
Blog Outline	Detailed, but generic	More structured, with better SEO suggestions
Email Draft	Polite but wordy	Concise, professional tone
Code Explanation	Good, but sometimes verbose	More technical, straight to the point

Surprise: Gemini’s responses were sharper and more to the point, while ChatGPT tended to over-explain.

Coding & Debugging

As a developer, I rely on AI for quick code fixes. Gemini CLI handled Python, JavaScript, and Bash scripts well, but with one big difference:

• ChatGPT explains errors in a beginner-friendly way.

• Gemini CLI assumes more technical knowledge but gives faster, more precise fixes.

Example:

python

# Buggy Code  
def divide(a, b):  
    return a / b  

• ChatGPT: "You’re missing a parenthesis after a. Also, consider adding error handling for division by zero."

• Gemini CLI: "SyntaxError: Missing ( in function definition. Fix: def divide(a, b):"

Verdict: Gemini is better for experienced devs, ChatGPT for learners.

Day 4-5: Research & Fact-Checking

Accuracy & Hallucinations

Both AIs sometimes make up facts, but Gemini CLI seemed more cautious with uncertain answers.

• Asked: "Who invented the first computer?"

  • ChatGPT: "Charles Babbage (with Ada Lovelace)."

  • Gemini CLI: "The concept evolved over time, but Charles Babbage designed the first mechanical computer. Do you need more details?"

Gemini’s nuanced responses felt more reliable.

Web Search Integration

Unlike ChatGPT (which requires plugins for live search), Gemini CLI can fetch recent data with a simple flag:

bash

gemini query --web "latest AI trends 2024"

This was a game-changer for research-heavy tasks.

Verdict: Gemini wins for real-time accuracy.

Day 6-7: The Final Verdict

Where Gemini CLI Shines

✔ Speed – No lag, instant responses.
✔ Precision – Less fluff, more direct answers.
✔ Terminal Integration – Perfect for devs and power users.

Where ChatGPT Still Wins

✔ User-Friendly – Better for non-techies.
✔ Memory – Remembers conversation history.
✔ Creative Writing – More "human-like" storytelling.

Will I Switch Permanently?

For coding & research? Yes—Gemini CLI is blazing fast and precise.
For casual chats & brainstorming? No—ChatGPT feels more conversational.

Final Thoughts

Gemini CLI is a powerhouse for technical users, while ChatGPT remains the king of accessibility. If Google adds chat history and a smoother UX, Gemini could dominate.
