Pencil
Pencil is a cross-platform desktop app for creating wireframes, mockups, and interface prototypes for websites and software projects.
What is Pencil?
Pencil is a GUI prototyping and sketching application that helps users design wireframes, mockups, and user interface concepts before development begins. It is aimed at designers, developers, business analysts, and anyone who needs to communicate screen layouts or workflow ideas clearly. The app provides a desktop workspace for assembling interface elements, building page flows, and exporting designs for sharing with teammates or clients. Pencil is available as a standalone app for macOS and other desktop platforms, making it useful for offline design work and early-stage planning. It is published by Evolus as an open-source project and is commonly used for low-fidelity product design, documentation, and visual requirement gathering.
Key features
- Create wireframes and interface mockups with drag-and-drop elements
- Build multi-page prototypes for app and website flows
- Use built-in shape collections and UI stencils for common layouts
- Export mockups to documents, images, and other shareable formats
- Sketch early product ideas without needing a full design suite

Safety overview
Status: Safe
Pencil is a legitimate desktop design tool used to create mockups and interface prototypes. It typically works with files you open or save in the app, which is normal for design software. If you no longer use it, removing the app mainly affects your ability to open or edit Pencil project files unless you keep exported copies elsewhere.
Recommendation: Keep Pencil if you use it for wireframing, mockups, or interface planning. If you do not use it anymore, you can remove it like other desktop apps, but keep any project files or exports you still need first.
