I Replaced My Entire AI Stack With One Free App

At one point I was paying for ChatGPT Plus, Perplexity Pro, a Midjourney subscription, a dedicated AI writing tool, an AI coding assistant, and one more thing I'm too embarrassed to name. I told myself each one was essential. Each one did something the others didn't. Then I actually sat down and looked at what I was getting for the money and I felt stupid.

The app I switched everything to is Claude — specifically Claude Code for anything technical, and Claude.ai for everything else. ChatGPT Plus: gone. Once I learned how to properly brief Claude and load context, the output quality wasn't close. Perplexity: gone. Claude with web search does the same job without a second subscription.

The AI writing tool: gone. When your context is set up correctly, Claude writes in your voice better than a dedicated writing tool ever did, because it knows more about you. The coding assistant: gone. Claude Code replaced it entirely and went further than any standalone tool I'd used.

Most people build an AI stack the same way they built a software stack five years ago — one tool per job. But Claude is not a single-job tool. It's a reasoning engine that can take on almost any job if you give it the right context and the right role. The reason people feel like they need multiple tools is usually that they haven't figured out how to fully use the one they already have.

The money I save isn't the interesting part. The interesting part is having one place where everything lives — my context, my projects, my voice, my decisions — instead of scattered across six different apps that don't know each other exist. Clarity of tooling leads to clarity of thinking. One tool, used deeply, beats six tools used shallowly every time.
