For me, the biggest productivity improvement hasn't really come from discovering one new AI tool. It's been learning how to use a smaller number of tools for specific jobs.
I use ChatGPT quite a bit for research, planning, working through problems, and organizing projects. I've also used Claude, Gemini, and Perplexity, but one thing I've learned is that having access to more AI tools doesn't automatically make me more productive.
I was spending too much time comparing tools and moving between them. Productivity improved when I started asking, "What does this tool actually do better than the one I'm already using?"
If I can't answer that, I probably don't need another subscription.
That has probably saved me as much time as any individual AI feature.
