Notion is a great note-taking tool.
Just recently, they changed their free plan.
They had a free plan from the beginning but limited how much pages/blocks you can save. Now you can save unlimited pages and blocks.
My issue with a “free” plan is that the terms of what they offer for free can change overnight.
If you rely on a product, pay for it!
As of this writing, I’ll continue paying for Notion. I use it every single day to manage tasks and outline and write tutorials.
