TagSpaces is a privacy-focused, cross-platform file manager designed to help you organize, tag, and browse your files without relying on external cloud services or user accounts. It works seamlessly on Windows, macOS, Linux, and in any modern web browser.

With TagSpaces, you can manage your local folders or connect to S3-compatible cloud storage such as AWS S3, Wasabi, or Garage. The app lets you add tags, descriptions, and geo-tags to files and folders, making it easier to find, group, and visualize your content.

Powerful built-in viewers allow you to preview documents, images, videos, and even 3D models directly inside the app. Advanced features in TagSpaces Proโ€”like the Kanban board, FolderViz visualizations, and AI-assisted taggingโ€”help you stay organized and productive.

Unlike traditional cloud-based solutions, TagSpaces gives you complete control over your data. Your files remain where they belongโ€”on your own devices or trusted serversโ€”ensuring full privacy and independence.

ContractDecoder helps freelancers, small business owners, and small teams understand contracts before signing or replying.

Users can upload or paste an agreement and get a plain-English review workspace with key terms, obligations, deadlines, items to review, practical questions, possible clarifying wording, and a draft email they can edit before sending.

It is useful for client agreements, vendor contracts, NDAs, service agreements, lease agreements, and project terms where the user wants a clearer starting point before going back to the other side or seeking further review.

ContractDecoder is free during early access. General information only. Not legal advice.

TagSpaces features and specs

  • Cross-Platform Compatibility
    TagSpaces is available on multiple operating systems including Windows, macOS, Linux, Android, and iOS, making it accessible across various devices.
  • No Vendor Lock-In
    The application does not lock users into any specific ecosystem, offering more freedom in choosing storage solutions and ensuring data portability.
  • Offline Functionality
    Works offline without requiring internet access, which enhances privacy and allows continuous access to files without dependency on cloud services.
  • Open Source
    Being an open-source software, its code is publicly available for inspection, modification, and enhancement, fostering transparency and community-driven improvements.
  • File-Based Tagging
    Tags are stored within the file names or in sidecar files instead of in a centralized database, which makes the data portable and not dependent on the application.

Possible disadvantages of TagSpaces

  • Limited Collaboration Features
    Unlike some cloud-based services, TagSpaces does not offer extensive collaboration tools, making it less ideal for team environments.
  • User Interface
    The user interface can be less intuitive and polished compared to other more mature file management and note-taking software.
  • Lack of Integration
    There are limited integrations with other software/services, which might require additional manual steps for users who depend on a broader ecosystem of tools.
  • Performance with Large Libraries
    Performance can degrade when dealing with very large libraries of files, as the application may struggle to index or retrieve files efficiently.
  • Feature Set
    While it covers basic needs, some advanced features available in paid or more mature software are absent, which can limit its utility for power users.

Questions & Answers

As answered by people managing TagSpaces and ContractDecoder.

Why should a person choose your product over its competitors?

ContractDecoder's answer:

ContractDecoder is a good fit for freelancers, small business owners, creators, consultants, and small teams who want a practical first pass on an agreement without learning a legal-tech platform. The output is organized around what the user needs to understand, check, ask, and discuss before signing or replying. It is also free during early access.

How would you describe the primary audience of your product?

ContractDecoder's answer:

ContractDecoder is for freelancers, consultants, creators, small business owners, and small teams reviewing client agreements, vendor contracts, NDAs, service agreements, lease agreements, or project terms. It is especially useful when someone wants a clearer starting point before going back to the other side or seeking professional review.

Which are the primary technologies used for building your product?

ContractDecoder's answer:

ContractDecoder is a web application built with JavaScript and hosted on Netlify, with Supabase for authentication and saved workspaces, and OpenAI-powered analysis for contract review outputs.

What makes your product unique?

ContractDecoder's answer:

ContractDecoder is built for the moment before someone signs or replies to a contract. It does not just summarize the document. It turns the agreement into a plain-English workspace with key terms, obligations, deadlines, review items, practical questions, possible clarifying wording, and a draft email the user can edit before responding.

What's the story behind your product?

ContractDecoder's answer:

ContractDecoder was built around a simple problem: many people are expected to review contracts before signing, but they do not always have the time, budget, or legal background to turn dense contract language into practical questions. The goal is to help users move from "I am not sure what this means" to "Here is what I need to ask."
