It comes with plenty of features for PKM, like graph view that you can search within using Obsidian's chosen node-based search, powerful backlink, and block referencing abilities that allow you to reference blocks across your account within notes that exist, and a canvas mode that has been added to help you bring ideas in your Obsidian account onto a canvas view to help you reorganize them, Obsidian might not be for everyone, so there are a wide variety of alternatives to Obsidian, many on this list.
Obsidian is the best free PKM solution on the market. If you're on one device, Obsidian is free forever, meaning you can use it and store those PKM notes on your device without having to worry about upgrading.

Tana is one of the more advanced PKM tools and has many powers. Tana is a note-taking app focused on system-based organization. It comes with powerful features like supertags, AI abilities & a growing community of users.
Features like graph view, superstars, and AI abilities help you better organize PKM notes in one place. Supertags are a unique system in Tana that allows you to apply the power of templates to each of the notes you take. They allow you to add critical metadata to notes that you can reuse, which makes things easier with search.
Many people already use the concept of supertags in apps like Capacities; they are object-like tags that help you re-use certain types of notes for powerful resurfacing.
If you're open to learning something a little more advanced than tools like Obsidian, Tana can offer you a whole load of features along with it. This one is probably the most difficult to learn, but users love it.
Logseq is a popular PKM tool as it offers great free access & powerful features. Logseq is a note-taking app with a focus on connecting notes. It has features like whiteboards, flashcards, and powerful networked thought abilities.
It allows you to take notes, connect them up, and see them within a graph view.

Features like whiteboards allow users to bring ideas together in one and daily notes allow users to journal within the app to express ideas.
If you're hunting for a similar tool to Obsidian, whiteboards as part of the experience, and a powerful way to connect up notes, then this is an interesting option. Logseq also has flashcards, which don't work as well as RemNote, but it does offer an additional thing that Obsidian does not have natively.
Reflect Notes is a note-taking app that focuses on handling notes and tasks and organizing your upcoming meetings from Google Calendar as notes for agendas and more. It is also focused on secure note-taking with E2E encryption.
Reflect Notes integrates artificial intelligence to streamline the management of notes, meeting notes, and ideas, making it a smart companion for those seeking efficiency.
Its user-friendly design makes the integration of AI into everyday knowledge management seamless and approachable. The AI's ability to provide smart summaries and insights is a game-changer, offering users the ability to save time while enhancing the overall productivity of their knowledge management efforts.
As a PKM tool, Reflect Notes sits between a traditional tool and a PKM app, allowing you to have the traditional feel of Evernote but the power of Obsidian. If you're looking for something that you want to feel secure with, test AI abilities, and add new features like task management and audio notes, then Reflect Notes is an attractive bet.
Heptabase is a visual note-taking app designed to help you bring ideas together in a canvas view. It allows you to add and link notes, which is popular with researchers and students. Heptabase is perfect for visual thinkers & those who want to get into PKM.
It balances both worlds very well by having a canvas mode that allows you to add ideas by dragging them together much like apps like Miro and Milanote. Hetpabase even has some project management abilities like Kanban views which people will like if they want more structured ways to manage all their knowledge base. It makes for a different, yet great PKM for visual thinkers and those who like open-plan ways of bringing ideas together.
Heptabase currently does not have AI, but it is a YC-backed company, and many people expect it to introduce AI functionality for note-taking shortly.
If you're a researcher, student, or visual thinker, Heptabase is a must-try. The application perfectly bridges the gap between handling notes in a PKM style whilst still being able to express them in a whiteboard fashion.
Roam Research offers a more traditional and structured way to connect ideas and notes, emphasizing networked thought strongly. Its bi-directional linking feature creates a deep, interconnected web of knowledge, catering to users who prefer a systematic approach to organizing their thoughts.
Roam Research's methodical and thorough knowledge organization style is particularly well-suited for users who seek a meticulous and interconnected system for their ideas and information.
Roam isn't a cult, either; this is a common misconception. They have a strong community of loyal followers who hold opinionated views on their application and software.
Roam Research is less attractive than many of the options on this list but still is very functional and powerful for PKM management. If you're wallet-conscious, Roam is still one of the more expensive note-taking apps on the market.
