I tested 5 AI chatbots with the SAME prompt for 7 days – here’s which one actually made me more productive (honest breakdown)

The setup:

I used ChatGPT, Claude, Gemini, Perplexity, and Grok with the EXACT same prompts for my daily work tasks:

– Writing marketing emails

– Analyzing customer data

– Creating social media content

– Debugging code for automations

– Research and summarization

Here's what I found after 7 days:

ChatGPT (GPT-4o): Still the best all-rounder. Fast, reliable, handles context well. But sometimes gives that "AI smell" in writing. 8/10

Claude: Honestly surprised me. Better at nuanced writing and actually follows instructions more precisely. Caught errors ChatGPT missed. 8.5/10

Gemini: Great for research with citations. Struggled with creative tasks. Felt like it was trying too hard to be safe. 6.5/10

Perplexity: BEST for research, hands down. Live sources + citations saved me hours of fact-checking. But not great for content creation. 7/10 (9/10 for research only)

Grok: The wildcard. Unfiltered answers were sometimes hilarious, sometimes useless. Fun but not reliable for work. 5/10

The unexpected winner for productivity?

Using them TOGETHER. ChatGPT for first drafts, Claude for refinement, Perplexity for fact-checking.

My honest take:

No single AI "won." The real productivity hack is knowing which tool to use for what.
