Saber is the notes app built for handwriting. It's designed to be as simple and intuitive as possible, while still delivering unique features that you'll actually use. Additionally, Saber is available across all your devices, large and small, and syncs between them seamlessly. Only you can access your notes. You can sync your notes across devices knowing that they are encrypted and stored securely, and not even the server can read them. Notably, it can invert your notes when you're in dark mode. This allows you to write with white ink on a black background, which is much easier on the eyes in low-light environments like when the teacher turns off the lights in class. Images and PDFs are also inverted, so you can still use a digital printout or a textbook without the fuss. Saber uses a dual-password system to protect your notes from anyone but you, even if they have complete control over the server.

Kivixa is a free, open-source, privacy-focused productivity workspace combining note-taking, drawing, planning, and offline AI assistance. It supports rich Markdown documents, handwritten notes, PDF annotations, and an infinite drawing canvas. Users can organize projects, tasks, calendar events, and interconnected knowledge graphs. Its local AI engine supports multiple language models for summarization, semantic searching, and contextual questions. MCP integration enables AI-assisted file operations with user confirmation. Offline speech recognition, voice notes, and text-to-speech expand its accessibility tools. Automatic version snapshots preserve document history and allow earlier versions to be restored. Built with Flutter and Rust, Kivixa also offers focus timers, Lua scripting, and cross-platform synchronization.

PicGuard is a free, open-source watermarking application designed to protect photographs and establish visual ownership of digital images. It allows users to add personalized watermarks to pictures through a straightforward editing interface. The software provides adjustable watermark colors and opacity to accommodate different image styles. Additional customization options include font selection, text sizing, and spacing in the Pro version. PicGuard processes images locally instead of uploading them to external servers, helping preserve personal privacy. Its Flutter-based architecture provides a consistent experience across web browsers, desktop computers, and mobile devices. Available for Windows, macOS, Linux, Android, and iOS, it offers photographers and content creators a convenient way to mark and personalize their images.

Pixes is a free, open-source, unofficial Pixiv client designed for browsing digital illustrations and artwork across multiple devices. It provides an alternative application interface for accessing content published on the Pixiv platform. Users can explore illustrations, discover artists, and navigate artwork collections through the application's browsing features. The software implements the main functionality expected from a Pixiv client, including access to artwork and related information. Its interface is developed using Flutter, allowing a consistent experience across desktop and mobile operating systems. The project is distributed under the MIT license and can be built from source. Available for Windows, macOS, Linux, Android, and iOS, Pixes offers an independently developed way to access the Pixiv illustration community.
