NdxCards is productivity software for the busy student, academic or professional. It uses the idea of a note card to capture anything one would like to retain and reuse (an idea, something read or heard, a recipe, boilerplate text, or photo) and organizes them using keywords, sources, authors etc. Get a blank note with a mouse click / hot key. Type or copy / paste directly from web sites, e-mails, other applications. Format the text (bold / bullets / numbers.) Set color for each note. Type-ahead data entry fields automatically complete subjects, keywords, sources etc. Taking notes is easy in a meeting or a class, or when reading from a book or web-site. Retrieving notes is intuitive. Mark notes with 'push pin' and find them with one-click. Link a note to many keywords - your own keywords. Search for specific notes using keywords, subjects, dates or a combination of criteria. Work with standard software, and use the notes you took. Drop notes into PowerPoint and analyze notes visually, drawing links between cards and inferring relationships. Highlight a set of note cards from the notes list and copy/paste contents into MSWord without opening each note card. Paste to Excel as an action register. Create projects to organize note cards in an outline with headings and export a draft document including a bibliography list of the sources you used. Collaborate by sharing cards with colleagues. Pack cards and send it to a team member. Build a shared knowledge base this way.
