Logseq vs RemNote: pricing, features and which to choose

Logseq began in 2020 as an open-source project and grew into one of the best-known privacy-first alternatives to Roam Research and Obsidian. Its GitHub repository has more than 45,000 stars, and its code is licensed under the AGPL. A small core team, about four people according to its forum, builds the app with community contributors, and it is funded partly through Open Collective sponsorships. Logseq attracts students, academics, writers, researchers and software developers who think in outlines and want notes that link together without handing their data to a cloud service. It runs on Windows, Mac, Linux, iOS, Android and the web.

Everything in Logseq is a block in an outline. You write in a daily journal by default, then link ideas with [[page]] references or #tags, and backlinks show where every page is mentioned. Blocks can be embedded or referenced elsewhere, so one idea can appear in many contexts. Built-in features include tasks with TODO and NOW states and scheduled dates, queries that pull blocks matching conditions, a graph view, whiteboards for spatial thinking, flashcards with spaced repetition and PDF annotation that links highlights back into notes. The original version stores pages as Markdown or Org-mode files in a folder you choose, so other tools can read them.

Logseq's strengths are its open-source license, local-first storage, powerful block references and queries, built-in journals, flashcards and PDF annotation, and a path to AI through MCP and plugins. Its weaknesses are a long transition to the DB version, beta-quality features, a slower release pace than commercial apps and a learning curve for queries. Obsidian has a larger plugin library and file-based notes, but is not open source. Roam Research pioneered the block outliner as a paid service. Tana and Capacities add structured objects and built-in AI. Notion suits team wikis. Choose Logseq if you want a free, open-source outliner that keeps notes on your own device.

RemNote is a study app built around one idea: the notes you take should become the material you review. It was founded by Martin Schneider, who leads the company as CEO, and it is aimed at students in medicine, law, languages and other subjects with heavy memorization, as well as lifelong learners. Notes are written as nested bullet points, and any line can be turned into a flashcard with simple syntax. Those cards then enter a spaced repetition queue that schedules reviews shortly before you are likely to forget. Because notes and cards live in the same place, editing a note updates its card, and every card links back to its context.

The note side works like an outliner. Each bullet, called a Rem, can be referenced from other pages, tagged and nested, which builds a linked knowledge base over a semester. Students can import and annotate PDFs, highlight text and create cards from highlights, add images and use image occlusion cards that hide parts of a diagram for anatomy or maps. Handwritten documents are supported for tablet users. An exam scheduler lets you set a test date so reviews are paced toward it. RemNote runs on the web and has desktop and mobile apps, and the free plan syncs across an unlimited number of devices.

RemNote's strengths are the tight link between notes and flashcards, a mature spaced repetition scheduler, PDF annotation that feeds cards, and an AI tutor grounded in your own material. Its weaknesses are a learning curve for the outliner and card syntax, tight document limits on the free plan and AI features that push heavy users toward Pro+AI. Anki is the free, highly customizable flashcard standard. Quizlet suits quick study sets. Knowt turns notes into AI flashcards. Obsidian and Logseq are general note apps with flashcard plugins. Choose RemNote if you want to write notes and review them with spaced repetition in one app.
