Knowledge management from your Terminal. Notetaking, journals, linking, search and more!

Create and manage your notes, journals, and templates in a local Vault with Fern in a beautiful Terminal UI. The power of heavier GUI knowledge management software all without leaving the terminal! Full-text searching, linking with markdown or wikilinks, tabs, split panes, multiple language translations, and a keyboard-driven interface.

Fern also comes with several color themes built in which can be easily toggled from a Command Palette. It supports managing multiple Vaults and allows for fast switching between them.

This snap is strictly confined. Fern stores its own config, state, and cache data inside the snap's per-user common data directory, so settings and indexes persist across snap revisions. For vaults on USB drives or other external media, connect the removable-media interface after install.
