Most people solve LeetCode problems and never write them up. The template shows up after you've already spent 40 minutes, so you close the tab. SQLens drafts the write-up from the code you wrote. Two minutes instead of fifteen. It'll solve easy and medium problems too, but only after a thinking timer you set yourself and can't cancel. Tags every problem by topic. Exports everything as a revision PDF. Saves nothing unless you press the button. Free tier. No account. Your own Groq key.
