Frequently Asked Questions
How does the notes summarizer organize my notes?
The tool uses TF-IDF-inspired word frequency analysis to identify key topics in your notes. It detects action items using pattern matching for common task indicators (TODO, "need to", "should", "must", etc.), groups related lines by shared significant words, removes duplicate or near-duplicate content, and produces a clean hierarchical output.
Is my data sent to any server?
No. All processing happens entirely in your browser using client-side JavaScript. Your notes never leave your device, making this tool completely private and safe for sensitive meeting notes or confidential information.
What is the Cornell Notes format?
Cornell Notes is a proven study method that divides notes into three sections: a narrow cue/keyword column on the left, a wider notes column on the right, and a summary section at the bottom. This format is excellent for studying, reviewing, and retaining information from lectures or readings.
What types of notes work best with this tool?
This tool works best with notes that contain distinct ideas, points, or tasks -- such as meeting notes, lecture notes, brainstorming sessions, research notes, or project planning notes. Notes with at least 5-10 distinct lines or ideas produce the best results. Single short paragraphs may not benefit as much from reorganization.
