Personal knowledge management (PKM) is the habit of capturing what you read, learn and think, then connecting it so you can find and reuse it later. A good PKM app makes capture fast, links ideas to each other and keeps notes yours, ideally in plain files you can export.
The tools below range from linked-note apps and outliners to read-it-later services and AI tools that summarise and resurface what you saved. If you are starting out, pick one place to capture everything, add links between notes as you go, and review weekly rather than building a perfect system on day one.
