What It Is

SEN positions itself as “a /home for your thoughts.” It is a local-first personal knowledge management project for the desktop. It turns everyday objects into desktop files, then connects files, notes, books, movie references, and source-code dependencies through semantic links, dynamic relationships, and metadata enrichment. The website clearly emphasizes open-source, filesystem integration, and Local First. At this stage, it feels more like an early prototype ahead of a technical preview.

Core Features and Product Form

Based on the available content, SEN is not centered on traditional cloud collaboration for enterprise SaaS. Instead, it aims to embed a personal knowledge graph into the desktop file system. Typical capabilities include connecting objects with stable semantic links, dynamically extracting relationships between files, enriching metadata on demand from remote open sources, and retrieving object information through the system search panel. Example use cases include library collection management, ISBN/title metadata lookup, linking reading notes to pages and chapters, connecting movie notes to timecoded scenes, and quickly navigating source-code dependencies without opening an IDE.

Pricing, Trial, and Deployment

The website does not disclose plans, pricing, payment methods, or any commercial edition roadmap. It offers a Join Waitlist option for early access to the technical preview, and users can subscribe to the blog for updates. In terms of deployment, SEN is explicitly desktop-based, local-first, and integrated with the file system. The screenshots come from a functional prototype running on Haiku, but there is no information on Windows, macOS, or Linux support. Cloud deployment or self-hosted services are also not mentioned.

Pros and Cons

Its strengths lie in a clear product philosophy: local data control, open source, a filesystem-native experience, and deep linking capabilities oriented around a knowledge graph. It is well suited to users who value data ownership and long-term knowledge accumulation. The drawbacks are equally clear: the product is still early, with no stable release, pricing, platform compatibility details, permission/collaboration model, security and compliance information, API documentation, or commercial support. For enterprise software procurement, the currently available information is not sufficient for a team-level deployment evaluation.

Who It’s For and Access from China

SEN is better suited to personal knowledge management enthusiasts, researchers, developers, and technical users willing to try early-stage tools. It is not a good fit for enterprise teams that require mature permissions, auditing, multi-user collaboration, and SLAs. The available content does not make it possible to assess access from China, and payment methods have not been disclosed. For mature alternatives, consider Obsidian, Logseq, DEVONthink, Notion, or Tana. If domestic access and collaboration in China are priorities, tools such as 语雀 and 飞书文档 may be worth evaluating separately.
