Die Methode der ABC-Liste ist eine Kreativ- und Denkmethode. Sie wurde von Vera F. Birkenbihl entwickelt und findet sich heute in unzähligen Kontexten wieder, wo es darum geht das eigene Gedächtnis anzuzapfen und über Assoziationen neue und kreative Ideen zu generieren. Du kannst ABC-Listen z.B. nutzen um: * Ideen für einen Artikel, einen Vortrag oder ein Buch zu sammeln * Lösungen zu einem Problem zu finden * Kreative Antworten für eine Fragestellung bringen * Geschenkideen für Deinen besten Freund sammeln Anwendung: Schritt 1: Gib ein Thema ein, zu dem Du Ideen sammeln möchtest. Schritt 2: Gib Dir einen Zeitrahmen von 2-10 Minuten. (Psst… Du kannst nach Ablauf des Timers noch weitermachen) Schritt 3: Mit „Start“ gehts los Schritt 4: Tippe Deine Assoziationen zu dem Thema ein und bestätige jedes Wort oder jede Phrase mit Enter. Beachte dabei die Tipps unten. Schritt 5: Wenn Du fertig bist, tippe auf „Fertig“ Schritt 6: Tippe auf Dein Thema in der Auflistung der ABC-Listen und Dein Ergebnis wird in die Zwischenablage kopiert. Du kannst es dann in einer beliebigen App einfügen (z.B.: Mail, Notizen, …)\ Tipps: Tipp 1: Du musst die Buchstaben nicht der Reihe nach durchgehen. Auch durcheinander ist erlaubt. Tipp 2: Lass Deinen Blick immer wieder über die Liste schweifen. Dann hast Du möglicherweise neue Assoziationen. Tipp 3: Buchstaben dürfen leer bleiben - oder auch mehrfach befüllt werden. Lass Dich da nicht einschränken.

Stop burying your ideas in digital graveyards and start building a structured web of knowledge with the original Zettelkasten method. SlipBox is a minimalist note-taking tool designed for those who value intentionality over automation.

This design forces you to physically move through your ideas, facilitating the active recall and spontaneous pattern recognition necessary for deep cognitive work. Key Features for Your Second Brain: Continuous Scroll Interface View your notes in a single, fluid stream to rediscover forgotten insights and spark new ideas. The Luhmann Workflow A digital implementation of the Zettelkasten method that respects the principle of atomicity (one idea per card). Intentional Tagging Organize notes manually to build deep mental maps and avoid the "out of sight, out of mind" trap of folders. Minimalist Design No steep learning curves or bloated features, just you and your knowledge. Privacy-First & Local Your data stays on your device, ensuring your private thoughts remain truly private. Build a knowledge system that grows with you. Turn your fleeting notes into a structured, permanent repository of thought with SlipBox.
