On This Day I

This plugin for Obsidian adds AI commands for daily journals.

Features

This plugin comes with two commands:

Add Placeholder at Cursor

Adds a custom tag at your cursor location which the generation command looks for and replaces if it is available. The tag can be changed in settings. A tag command and setting should be available for each generation command.

Generate Through The Years

Uses AI to find Daily Notes from the same date as your current note in years past. Generates a brief summary of this date for each instance of it through the years and places it in your note.

How to Use

• Enable the plugin in the settings menu and update the plugin settings accordingly.
• Open the command palette and search for On This Day I to see the commands.
• If you want the output to be placed at a certain location in your note, add a placeholder (default is <!OTDI>, can be changed in settings). Run the On This Day I: Add Placeholder at Cursor command if you'd like to automatically add a placeholder to your note at cursor location.
• Run the command On This Day I: Generate Through The Years to generate your yearly insights.

OpenAI

• This plugin makes a network call to the OpenAI API to generate the journal summaries.
• Must have OpenAI API key. See platform.openai.com. Add this key to plugin settings.
• Model can be adjusted. Currently support gpt-3.5-turbo and gpt-4. Older models will be cheaper and often faster, but newer models will have higher quality outputs.

Through the Years Date Requirements

• Must be run from a note with a valid Date format. Update the date format in settings to match your daily note format.
• Daily notes must all follow the same date format (e.g, MMMM D, YYYY would be something like February 6, 2025)
• There must be at least one other daily note from this day in a past year.
