UpNote is a note-taking tool that helps you write, organize, and find your notes quickly. You can create notes with text, images, files, and even tables. The app works on iPhone, Android, Mac, Windows, and Linux, so you can access your notes from any device.

Tangent Notes is a note-taking app that treats your thoughts like a web of connected ideas. When you write, you can link notes together using simple double brackets, just like Wikipedia. As you follow these links, Tangent remembers where you have been and shows your path with sliding panels that move horizontally across your screen.

Capacities is a note-taking and knowledge management app built around objects instead of traditional folders. When you create a note about a person, book, or project, it becomes an object you can easily link to other notes. This makes finding connections between your ideas much simpler.

Reor is a note-taking application that uses artificial intelligence to help you manage your knowledge. When you write notes, the app automatically finds related content from your other notes and shows them to you. This helps you discover connections you might have missed.

Blinko is a self-hosted note-taking application that combines simplicity with powerful features. Unlike cloud-based tools where companies store your data, Blinko runs entirely on your own computer or server, giving you complete privacy. The app organizes content into two categories: quick notes called "Blinkos" for instant capture, and full "Notes" for detailed information you want to keep long-term.

AFFiNE is a workspace application that brings together three main tools in one place: documents for writing and note-taking, whiteboards for visual thinking and drawing, and databases for organizing information. Unlike cloud-first tools, AFFiNE takes a local-first approach, which means your data lives on your computer first and only syncs to the cloud if you choose.

SiYuan is a personal knowledge management system that treats every piece of content as a block. These blocks can be linked, referenced, and organized in multiple ways. Unlike traditional note-taking apps, SiYuan gives you complete control by storing everything locally on your device.
