What’s one AI tool that actually stayed in your workflow?

Feels like every week there’s a new “revolutionary” AI tool with a flashy landing page and dramatic claims, and then I try it once and forget it exists.

Has anything you’ve tried recently earned a permanent spot in your daily or weekly workflow?

Not the hype stuff, not the one-time demos. I mean a tool that genuinely surprised you and proved itself useful over the long run.

Would love to hear real recommendations from people who actually use these tools, not the marketing blurbs.
