What underrated AI tools have actually made you more productive in 2026?

I asked this back in 2025, but the AI landscape has changed a lot since then.

Not looking for the usual ChatGPT, Claude, Gemini, Midjourney, etc. I'm curious about the lesser-known tools that you actually kept using.

Could be for research, coding, design, video, writing, automation, planning, journaling, local AI, or even something oddly specific.

Free or paid doesn't matter.

What tool genuinely saved you time or improved your workflow this year? And what do you actually use it for?
