Write in Markdown
Choose from 3 layouts: editor-only, preview-only, or split view. Keep local Markdown and its live rendering side by side.
A PLACE FOR YOUR WORDS
Polarbear
Less between you and your next idea.
THE IDEA
A local-first Markdown workspace for writing, diagrams, and Git-based knowledge.
Your words deserve a home that keeps you close to the work. Polarbear brings Markdown editing, live preview, and diagrams into a desktop workspace, with GitHub and GitLab document workflows. Your local files remain at the center.
