ekg is an Emacs note-taking application that functions as a knowledge graph, storing all data in a SQLite database. It targets users seeking an alternative to tools like org-roam or denote, offering a unique approach where tags are primary, replacing traditional note titles. This design facilitates symmetrical backlinks and allows for granular note organization.

How It Works

ekg's core design philosophy is the equivalence of tags and notes, eliminating the need for explicit titles. Notes are identified and linked solely through tags, enabling a more fluid and interconnected knowledge base. This approach, combined with a SQLite backend instead of filesystem storage, allows for efficient querying and management of notes, especially when dealing with numerous small entries.

Quick Start & Requirements

• Install via MELPA: (use-package ekg ...)
• Requires Emacs 28.1+ and the triples and llm packages.
• Emacs versions prior to 29 require emacsql and a system sqlite binary.
• LLM/embedding functionality requires an API key for providers like OpenAI.
• Full manual: https://github.com/ahyatt/ekg/blob/develop/doc/ekg.org
• Video demonstration: https://youtu.be/qxa2VrseFUA

Highlighted Details

• Supports LLM embeddings for semantic search and LLM chat integration within notes.
• Notes can be attached to file or web resources.
• Imports from org-roam and supports import/export with Logseq.
• Features template-based note creation and prefixed tags for organization (e.g., date/, idea/).

Maintenance & Community

• Actively developed by ahyatt.
• Dependencies include triples and llm packages, also maintained by ahyatt.

Licensing & Compatibility

• License: MIT.
• Compatible with commercial and closed-source applications.

Limitations & Caveats

The project is described as "simple but opinionated," suggesting potential limitations for users preferring more conventional note-taking structures. While LLM integration is present, its setup requires specific provider configurations and API keys.
