Logseq is a great home base for collecting and organizing your knowledge. For beginners, start on the daily page and write. That's it. For the experienced, there is a lot of depth to what you can do. Great community, frequent updates. I come back to logseq time and again, despite leaving for weeks at a time to try other PKM. Hard to beat the effectiveness of the simplicity offered here.

Logseq is excellent for recording notes and ideas and finding connections between them. The way it links between pages is especially helpful. I usually do not have to do any manual organization of pages, yet can still find what I need. Logseq is an awesome tool and I would highly recommend that anyone looking for notetaking, brainstorming, or general life organization software give it a try.

My favourite knowledge management tool. I got hooked on networked note-taking with roam research, then had my time with Obsidian. All these tools are great, but Logseq outperforms everything I tried before. It has all the features I need + simple UI + free to use + open source + a supportive community. I don't know what else to ask for.

Super easy and interesting to use.

Super useful in my daily work life. I was skeptical about the daily journal approach at first, but using it to track my workday and link it to my knowledge and tasks has been amazing! Open source Knowledge base Community plugins PDF annotation Markdown support Local storage Data visualization Daily journal feature Simple ui Logseq is amazing for PDFs, but what if we treated emails the same way? Here’s a quick concept for a deep email integration that would allow for highlighting and linking directly within our journals.The goal is to treat emails as first-class citizens, similar to how Logseq handles PDFs.1. Integration & CaptureSecure Sync: Connect via IMAP or API (Gmail/Outlook).Easy Access: Use a /import email command or a dedicated sidebar to drag and drop threads directly into your Daily Journal.2. The "Email Viewer" (PDF-style)Side-by-side View: Clicking an email opens it in a split panel.Smart Highlights: Select text within an email to create a block reference in your notes.Automatic Metadata: Auto-populate properties like From::, Subject::, and Date::.3. Workflow IntegrationContextual Journaling: Link specific email paragraphs to your meeting notes or daily logs.Task Management: Convert emails into TODO items while maintaining a bidirectional link to the original message.Why it works:It eliminates the friction of switching between apps and keeps all professional communication indexed within your local graph, preserving context and privacy.

Open source, markdown based, backlinks, journal focussed

Great note taking tool, I center my notes around journal entries and use backlinks to group related notes. Open source Community plugins Bi-directional linking Daily journal feature One-click sync, currently only use it on my laptop but would love android support. (This is currently an alpha feature). This would make me ditch Notion completely.

Logseq has transformed my journal. I've previously used evernote. I've had collections of google docs. But the linking that comes so naturally in logseq makes it so much easier to find what you had before. The daily journals are brilliant .. I didn't use them much to start with, but now I find them so much more powerful than having individual pages, because of the inherent timeline. The bullet-as-a-doc provides easier focus, especially with being collapsible. And also, the in-app pdf with annotations are awesome. Thank you so much.

Logseq changed the way I take notes. I used to use Notion as my primary note taking system. Notion was not my first either. I used Evernote. Then moved to OneNote. And then moved to Notion. I was using Notion for a long time. But I felt Notion felt too heavy. It takes a lot of time to load. And it was very difficult to organize my notes. I had two options. If I want to take down some notes, either I need to find where I can put the notes or, I need to put them in Quick notes and later move them to relevant notebook. And opening different pages was very slow. I started looking for other choices. I found another category of note taking apps like Obsidian and Logseq. I tried out both. I loved the features of Logseq. So, I'm using it for a month for now. I'm stuck with Logseq for two reasons. The note taking is local. I keep the notes in local disk and sync it with git. This makes the note taking feels so fast. The second one is the way Logseq organizes the notes. I don't have to think about where to put notes. I can just backlink them wherever I'm writing the notes. When I want to look back at something, I find everything I need at the same place

Logseq is the note taking tool I have been waiting for. I've used paper, Evernote, OneNote, my own custom mix of SimpleMind + NeuralNote (an app I developed for Android to match the notetaking style I wanted), and finally Logseq. I have tried Obsidian. It is much more polished and has a more mature plugin marketplace, but IMO in it's effort to be more user friendly it has lost something that Logseq excels at; something worth a lot. If you use Logseq and adapt your notetaking to its outlier approach, you can effectively make Logseq your second brain, legitimately. With Logseq I can pause and resume thought chains when I don't and do have time for them, losslessly. I can examine and correct my thinking and provide a chain of custody for the thoughts that have led to the decisions I've made. It took me about a year to develop my current notetaking pattern in Logseq - I was too used to working with OneNote/Evernote/etc. that I wasn't leveraging the graph-based system effectively. Now that I'm fully on board, it's life changing.

Logseq's blend of intuitive design and powerful features is mesmerizing. The outliner-based note-taking is transformative; quickly jotting notes, connecting complex thoughts - all effortless. Bidirectional linking is a superpower, creating a web of knowledge. More superpowers come with its extensions / plugins; I recommend Bullet Threading, Matter, Tags, Tabs. Logseq's commitment to privacy stands out. Your data stays local by default, giving you complete control (however, I opted for the iCloud-Sync; works like beta-software.) The developers constantly engage with the community, tirelessly improving and expanding the platform. Hope they focus their attention on the iOS-App. Putting links etc. via the iOS-native share-feature in the app does not work reliable. I still use OneNote for that task. Logseq has revolutionized how I manage information - an absolute must for anyone needing to write, study, or organize thoughts more efficiently.

Without question, LogSeq is the most exceptional application I've come across in the last five years (let GPT appart). I started using it six months ago, and the bump in my productivity has been mind-blowing. Had someone suggested back then that it would replace Google Docs as my go-to platform for content creation, I wouldn't have believed it. LogSeq's strengths lie in its ability to seamlessly organize thoughts and information, making retrieval and reuse a breeze. However, I must admit that it does present a bit of a learning curve. But once you are familiar with it, you'll find that time invested in learning it is undoubtedly well-spent. This is a tool that truly transforms the way you work.

I love using it. It makes note-taking fast and fun and I no longer want to use anything else for personal knowledge management. Sometimes the UI is confusing and the wrong set of blocks get selected, but it's infrequent enough to be merely a minor annoyance. The advanced query feature is poorly documented and really hard to use well. It's actually a programmatic interface that sits right there among the GUI features, and one is tempted to use it expecting it to be easy. That is not at all easy.

I've been trying to find a robust, straight-forward and versatile platform for hosting information for an NGO project I'm working with as a hobby, preferably open source and free since we are are volunteers in this project. Logseq is all of those, and actually offers really versatile features. To use the more advanced queries there is a bit of a learning curve and the documentation is partially a bit thin, but its understandable since it is an open source project and evolving fast.

There are minor issues to work through, mainly the UI/UX, but at this stage, I am unable to function without this solution. The biggest issue it solved for me was that when I'm trying to capture information, I need as little friction as possible while capturing. Logseq's daily journal combined with the bi-directional linking makes it much easier to capture information while working much closer to how our brain functions (less static categorization and more linking between ideas).
