An honest review from a current manager who has used Gemini Advanced for one month. counterattack? well.

"Eventually, I go back to Google." This is a common saying from my acquaintances who were living as 'AI nomads', wandering between ChatGPT Plus and Claude, and recently settled on Gemini Advanced. Experts who have analyzed the rise and fall of the fierce software ecosystem also felt that Google's counterattack this time was a heavy blow.
But let me tell you straight: Gemini is not a 'writing tool'. If you pay 29,000 KRW per month expecting flashy sentences like ChatGPT, you'll regret it 100%.
Here starts a cold review from an expert who has gone through bone-crushing(?) practical testing for a month.

1. Three 'Real Finishing Moves' of Gemini Advanced
① Gmail and Google Docs 'come alive'
The biggest charm is that there's no need to switch windows. If you ask "Summarize this email and write a draft reply" in the Gmail right sidebar, Gemini reads the context and writes a reply for you. The same goes for Google Docs. While writing, if you click "Change this sentence to a more professional business tone," it immediately suggests corrections. It frees us from the primitive action of 'copy-pasting.'
② Overwhelming 'Long-term Memory' (Dignity of 2 million tokens)
The Gemini 1.5 Pro model has incredible memory. Even if you throw dozens of PDF documents spanning hundreds of pages at it at once, it accurately analyzes without confusing front and back content. If you upload years of meeting minutes and ask "What was the conclusion of this project last year?", it points to the exact location like finding it with a magnifying glass. This is truly a blessing for researchers or planners.
③ 2TB Storage as a bonus (Google One benefit)
Actually, it's safe to say that half of the subscription fee is for this cloud capacity. 2TB of Google One storage is provided, which has a magic-like effect that drops the actual AI subscription fee to the 10,000 KRW range for those who usually use Google Drive or Google Photos as a paid service.
2. Disappointing points from use: Too much 'AI-ishness'
Of course, the disadvantages are clear. I'll tell you everything without hiding it.
- Limitations of Korean writing: Logical reports or summaries are excellent, but marketing copy is still stiff and boring compared to ChatGPT or Claude. The stiff feeling of 'AI not understanding metaphors' is strong.
- Too much moral-focused style: Like Google, which emphasizes security and ethics, it often shuts its mouth saying "I cannot help you" even if a slightly sensitive topic comes up. Sometimes it feels like having too much of a straight-laced assistant.
3. Manager's 'Subscription Tips': Knowing when to enter and leave
- 1-month free trial is essential: Google usually gives a 1-month free trial period. At this time, upload the business documents you use most and test it yourself.
- Use Family Group: The Google One plan can share storage space with up to 5 family members. The value of storage sharing alone is huge.
- Cancellation defense tip: When you try to cancel the subscription, Google often makes a suggestion: "Would you like to try it for one more month for free?" At this time, it is the attitude of a wise subscriber to accept without hesitation.
❓ FAQ: Realistic questions most often asked before Gemini subscription
Q1. If I have to choose only one between ChatGPT Plus and Gemini? A: ChatGPT for document creation and creativity, Gemini for Google Docs integration and vast material analysis. Personally, I'd like to side with Gemini for business use.
Q2. Is data analyzed in Gemini used for training without my consent? A: If you use the paid version, security settings are strengthened, and you can manage it so that it is not used for general answer generation. However, it is the best ironclad rule to handle sensitive secrets in a closed network or offline environment.
Q3. Is there a big difference between free Gemini and paid? A: Yes, it's like heaven and earth. The free version uses an old model, and the paid version (Advanced) carries the latest engine called 1.5 Pro, so the reasoning ability is overwhelming.
