More repositories without their own artwork yet: .github (organization profile and shared community-health files)

This index covers every public doc-bricks repository visible on GitHub as of 2026-08-06. Private or internal repositories are intentionally not listed on the public organization profile.

• Local first: documents, mail exports, indexes, and reading state stay on the user's machine by default.
• Privacy-conscious: tools avoid cloud processing unless an external service such as Gmail is explicitly configured by the user.
• Document-practical: each project targets repeated real workflows: reading, previewing, cleaning, exporting, archiving, and handoff.
• Structured exports: JSON, BibTeX, PDF, and companion formats are documented so data can move between desktop tools and later automation.
• Readable maintenance: READMEs, tests, and llms.txt files are kept useful for both human maintainers and LLM-based assistants.

Useful search phrases for the public doc-bricks profile include local-first document tools, Python document management, PySide6 PDF OCR, DokuReader metadata JSON export, MediaBrain smart playlists private SQLite, Gmail IMAP attachment downloader, Markdown PDF export, literature manager GitHub, invoice mail OCR DATEV export, and local-first LLM agent notes.

For crawlers and LLM tools, see llms.txt. It lists the canonical repositories, project roles, and preferred search phrases for the doc-bricks organization.

doc-bricks is the document-work branch of the brick suite:

open-bricks | file-bricks | dev-bricks

Part of the ellmos-ai ecosystem: llm-note was extracted from ellmos-ai/bach's Notizblock/Denkarium patterns and remains usable as a standalone agent-notes skill.
