Ranked #4 on the daily ranking of Product Hunt, the world's largest product launch platform! ----- "Knowledge is built from multiple pieces of knowledge" is the concept behind this note-taking app. Each note consists of multiple text blocks, which can be individually copied or deleted. By adding links to other notes, you can refer to them while editing your current note. The main features are as follows: - Categorize notes with tags - Copy or delete individual text blocks within a note - Add links to other notes for reference - Text formatting using Markdown syntax (more options will be added) - note duplication (this allows for template-like usage) We hope that Linky Notes will help you organize your information more effectively in the future!
