The Beeminder Word Count plugin integrates Obsidian with Beeminder to help users track their writing progress. It allows users to send the word count of their current note directly to a specified Beeminder goal. The plugin only counts the actively selected text to ensure accurate reporting, which is ideal for users who edit the same file over multiple days. With customizable settings for Beeminder username, goal name, and API token, this plugin streamlines word count tracking for writers who rely on Beeminder for productivity and goal management.
