Logseq is an [[AGPLv3]] licensed knowledge management and note taking app written in [[Clojure#Clojurescript]]. - [Website](https://logseq.com/) - [Source](https://github.com/logseq/logseq) - [Documentation](https://docs.logseq.com) - [AlternativeTo](https://alternativeto.net/software/logseq/about/) > A privacy-first, open-source platform for knowledge management and collaboration. # Notability Seems to be a fairly powerful [[Org Mode]] based system. Has some really cool [[#Features]], but none of them overcome the [[#Missing Features]] when compared to [[Obsidian Editor]] unfortunately. # Philosophy ## Business Model The app is open source, but is backed by Logseq Inc, whose privacy policy language randomly switches from first person plural to singular and lists the contact info as `[email protected]`. The actual contact page lists `[email protected]`. There is a jobs page. Where are they getting their money from? In Feb 2021 the developer posted a question about what their business model should be. There is no pricing page on their website. There are plans for a "Logseq Pro" which will include syncing, real-time collaboration, and some unspecified network and local features. They commit to keeping all local features, even the paid ones, open source. The server software is not planned to be open sourced. Logseq Pro is supposed to have a 3-month trial window. # Platform Support # Features - Supports both [[Markdown]] and [[Org Mode]] note formats - Accessible via both browser and dedicated [[Electron.js]] app - Scriptable via Clojure - Simple Queries using some kind of Clojure subset - `{{query stuff}}` - `{{query (and [[page name]] "foobar")}}` - Advanced query system using [[Datascript]] on the backend and [[Datomic]] (a [[Lisp]]y dialect of [[Datalog]]) as the advanced query language - Query builder - Automatically embeds results locally, even using it in just a browser via a webpage (as demoed on their query builder section of the docs) - "Whiteboards", looks like Obsidian's canvas mode, but with added drawing tools - Right Sidebar Workspace - Pages can be opened in the right sidebar with "shift-click" (But I don't see a proper split feature?) - Items in the right sidebar stack up like vertical panes and can be closed or collapsed - `Contents` is a hard coded button there, it is *not* a table of contents for the current page, it is a kind of global pinboard for a list of links or other blocks which is *super annoying* and there is no good TOC plugin that I can find either - Blocks are a first-class feature (unlike Obsidian's blocks which feel bolted on) - Any block can be opened as a segment on the right sidebar, changes are synchronous between sideback and main page - Blocks aren't just single lines - Forward slash `/` allows you to insert any block type from paragraph to header to code block to image embeds ## Missing Features - No table of contents feature!!!!!! - Middle click does not seem to open links in a new tab - No syntax highlighting of the current block in Org Mode (weirdly code blocks themselves are highlighted live, so clearly the feature is available) - Doesn't fully support Firefox because it relies on a Chromium-specific version of the open [[File System Standard]] for web browsers - Dark theme toggle is hidden - Weirdly ugly layouts - Nested bullets are cluttered with borders, they collapse in a way that it is not clear what belongs to what bullet - Right sidebar is huge and eats up most of the page - Right sidebar shows a huge list of contents for the entire site rather than the table of contents for the current note - Left sidebar is just a top level nav, and when collapsed the whole thing disappears, there is no icon-only mode - Some links have visible square brackets around them `[[Link Name]]`, others don't, I think the difference is the way the link is defined, ironically making internal links stand out more than potentially external links - I think that all of these issues are due to the influence of [[Roam Research]] which looks very similar - Bad Navigation - Maybe this is from some other system, but wasting `Ctrl-p` and `Ctrl-n` on up/prev and down/next seems wild to me - Overall finding your way around the app is Not Fun and feels very complex with many things hidden - There's no simple folder list? - Definitely no "Evernote" style file list # Tips # References - https://docs.logseq.com/#/page/faq - https://discuss.logseq.com/t/what-is-logseqs-business-model/389 - https://discuss.logseq.com/t/what-is-contents-in-the-right-side-bar/10018/3 - https://discuss.logseq.com/t/outline-overview-for-sidebar/740/24
