While building a crypto notification bot, I developed a weird habit: copying the same question into both Claude and Gemini, then comparing the answers.
My journal at the time: "Pasting the same questions into Gemini and Claude and watching them disagree. This is more fun than I expected."
Round 1: Setup time estimate
Asked both how long Make.com automation setup would take for a beginner.
- Gemini: "20 minutes"
- Claude: "That's quite optimistic for a first-timer. Expect 1-2 hours. Also, the free plan has a 1,000 operations/month limit — worth knowing upfront."
Tried it myself. Claude was right.
Round 2: Code review
- Claude: "6.5/10. It works, but this code fails silently." (followed by a bug list)
- Gemini: "100 out of 100... but here are 5 things to fix."
Gemini's praise felt good at first. After the third time, I stopped trusting it.
Round 3: Error fixing
Had an error related to Gemini's API. Asked Claude — didn't work. Asked Gemini directly — solved immediately.
Turns out, ask the tool about itself.
The moment that stuck
Asked Claude: "What if I charge people for bot signals?"
Claude: "Companies with billions in funding already do this. Selling investment signals for money can also be a legal issue. Honestly, the only realistic angle here is selling the process of building this — not the signals."
Didn't want to hear it. Wasn't wrong.
Journal after that: "There's this AI called Claude. More realistic than Gemini. Ended up buying it."
Takeaway
It's not about which one is better. It's about knowing where to use each.
- Claude: uncomfortable truths, accurate bug spotting, realistic advice
- Gemini: fast drafts, knows its own API best, friendly step-by-step
Using both at the same time showed me things I couldn't see using either alone.
