Local-First Desktop Tools for Document Libraries, Reading, Mail Intake, OCR, Literature Management, and LLM-Agent Notes
Note
Local-First & LLM-Ready: All doc-bricks tools run locally on your system, keeping documents, PDFs, and notes private. Machine-readable context is available in llms.txt for LLM agents and crawlers.

| llm-note | Local-first notes and notebook inboxes for LLM agents, extracted from BACH Notizblock/Denkarium patterns |
- 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.txtfiles are kept useful for both human maintainers and LLM-based assistants.

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.
