Pensela: The Swiss Army Knife of Screen Annotation Tools

Pensela is an open-source tool for creating and annotating screenshots. With it, you can draw directly on the screen. Its UI is mostly a toolbar that houses all the tools for annotating images in a minimalist layout. The tools are accessible with a single click which promotes its design initiative to be light, versatile, dynamic, and elegant.

Nick-named the Swiss Army knife of Screen Annotation tools, Pensela has features that make it easy to draw shapes and add pre-added shapes in the form of stickers to images. It also features a highlighter, text support, custom color picker, background pages, a screenshot tool, and a laser pointer.

Pensela was first released in May 2021, so there are features listed to be added in a later stage of development. The features expected to come in later versions include a better UX, automatic updates, improved text support, a better laser pointer, separate colors for Stroke and Fill, and a full-fledged built-in Screen recording Tool.

Of course, contributions in different forms are welcome e.g. forking the project, installing the dependencies with npm, opening a pull request, or even creating your feature branch.
