I Tested 17 AI Tools Side by Side — Here's What Actually Matters

A few months ago I got tired of bookmarking AI tools I never used. My tab bar looked like a hoarder's garage — a writing assistant here, three "autonomous agents" there, a meeting summarizer I'd opened exactly once.

The goal wasn't to crown a winner. It was to figure out which differences I'd been obsessing over actually changed my day, and which ones were marketing.
