TagSpaces

TagSpaces is an offline-first, cross-platform application for organizing and managing local files using a flexible tagging system. It works without accounts or a central cloud backend by storing metadata alongside your files, keeping your data portable and private.

Key Features

• Tag files and folders using filename tags or sidecar metadata files
• Fast filtering and search, including a local index service for content search
• Built-in viewers and editors for common formats (text, Markdown, HTML, media)
• Note-taking and simple task lists stored as plain files
• Web Clipper browser extension to save web pages, screenshots, and bookmarks as local files
• Extensible architecture via custom viewers/editors (plugins)
• Optional local AI/LLM integrations (via Ollama) for summarization, tagging, and annotation

Use Cases

• Organize a personal document archive (PDFs, receipts, manuals) with consistent tags
• Build an offline personal knowledge base with notes, web clippings, and media
• Create a portable file-based workspace that can be synced with third-party tools

Limitations and Considerations

• Not optimized for working locations containing more than about 100,000 files

TagSpaces is well-suited for users who want a file-based, vendor-neutral way to manage documents, notes, and media. Its offline design and optional local AI features make it a strong choice for privacy-focused personal and small-team workflows.
