This plugin for Obsidian shows you a random text prompt, from a file in your vault, of your choice.

• Create a file in your vault that will contain Prompts, if you do not have one already.
• Add prompts to that file that you'd like to show yourself. A Prompt should be pure text, no markdown, and fit on a single line.
• In Obsidian Settings, find Prompt. Choose the file you created.
• In Obsidian, show yourself a prompt by either:
  • clicking the Sidebar button,
  • Opening Command Palette and choosing Show Random Prompt
  • Assigning a Hotkey to the Show Random Prompt
