What is TagSpaces and what can you use it for?

TagSpaces is a free, open-source file organizer for Windows, macOS, Linux, and the web. You use it to tag files and folders, write notes, clip web content, and preview many file types — all locally on your device, with no account or login required. It fits people who want tag-based organization without handing their files to a cloud service, and who are comfortable managing their own storage and optional sync tools.

How TagSpaces organizes your files

The core mechanism is that tags and metadata are stored beside your files, not in a separate database. According to the site, "tags, descriptions, and colors are stored right beside your documents," which makes the workspace portable and keeps your data in plain, readable files.

This has a practical consequence: because there's no central index, your organization travels with the files themselves across devices and platforms. The trade-off is that you're relying on the file system as the source of truth, so how you structure folders and name files still matters.

What you can use it for

Tagging files and folders

Add color-coded tags to any file or folder. Tags persist with the files rather than living in an app-specific store, so they remain meaningful outside TagSpaces.

Note-taking

Write notes in Markdown, HTML, or plain text. Each note is a standard file you control directly — no proprietary format lock-in.

Collecting web content

The Web Clipper extension for Chrome, Firefox, and Edge saves web content to your hard drive as plain files (HTML, MHTML/PDF, PNG, URL). You can save whole pages or parts of them, capture screenshots, create bookmarks (turning TagSpaces into a bookmark manager), and extract geo-coordinates from Google Maps or OpenStreetMap as geo-tags.

Browsing and previewing

Preview 50+ file formats in place — images, PDFs, audio, video, spreadsheets, source code, and more — without opening separate applications.

Offline AI chat

Each folder can have its own private AI chat via Ollama, llama.cpp, or LM Studio to summarize, describe, and analyze files. This runs fully offline, so it depends on you having one of those local model tools set up.

Key characteristics to weigh

Optional syncing is left to you — the site names Google Drive, Dropbox, Syncthing, and Nextcloud as examples, and Cryptomator for encryption. That flexibility is also a responsibility: backup and sync setup are yours to configure.

Is it a good fit?

TagSpaces suits you if you want tag-based file organization that stays on your machine, value portable plain-file storage, and are willing to manage sync and backups yourself. It's less suited if you expect a hosted service with automatic cloud sync and account-based collaboration out of the box.

You can download it for free or try the live demo before committing. A Pro edition exists with its own subscription terms, including a 14-day money-back guarantee and cancellation terms — check the Pro page for current details before relying on any specific plan.
