Obsidian logo Obsidian in brief

Obsidian is a desktop and mobile note-taking app made by Dynalist Inc., a small independent company founded by Shida Li and Erica Xu, and first released in 2020. It runs on Windows, macOS, Linux, iOS and Android. Notes live in a vault, which is a folder of plain Markdown files on your device, so they open in any text editor and outlast the app. Obsidian takes no venture capital and calls itself 100 percent user-supported. In February 2025 it made the commercial license optional, and the company says people at more than 10,000 organizations, including Amazon and Google, use it for work. Version 1.15 shipped in October 2026.

Writing happens in a Markdown editor with live preview. Typing double brackets links one note to another, and every note shows its backlinks, so ideas connect without a fixed folder hierarchy. The graph view draws those links as a network. Canvas gives an infinite board for arranging notes, images and web pages, and Bases, a core plugin added in 2025, turns notes with properties into sortable tables, cards or maps that work like a lightweight database. Daily notes, templates and tags cover journaling and task capture. The 1.15 mobile release added voice Quick Capture with live transcription on iOS 26, and PDF export on mobile.

Obsidian's flexibility is also its main drawback. A new vault is a blank editor, and building a useful system takes time and plugin choices. Real-time collaboration is limited compared with Notion, Microsoft Loop or Google Docs, and community plugins vary in quality and security. Notion suits teams that want shared databases and built-in AI. Logseq, which is open source, offers an outliner model with similar local files. Anytype offers local-first, encrypted notes with object-based structure. Pick Obsidian if you want notes that remain usable files in 20 years and are willing to add AI yourself; pick Notion for team wikis.

Roam Research logo Roam Research in brief

Roam Research helped make bidirectional links and block-based outlining popular in note-taking, and many later tools, including Logseq and Obsidian's linking features, are often compared with it. It was created by Conor White-Sullivan and is built for researchers, writers, founders and students who think by connecting ideas rather than filing them into folders. Instead of a hierarchy of documents, Roam is a graph of pages and blocks. You write in an outliner, wrap any phrase in double brackets to create or link a page, and every page shows the linked and unlinked references pointing to it. Over months, that reference list becomes a record of how an idea developed.

The block is Roam's core unit. Each bullet has its own identifier, so you can reference or embed it in another page and edits show up everywhere it appears. The daily notes page opens each day as a default place to write, which removes the decision of where a thought belongs. Tags, attributes and queries pull blocks from across the graph into one view, and a graph view shows how pages connect. Roam also supports to-dos, kanban and table views, a sidebar for working on several pages at once, version history for blocks and keyboard-driven navigation. Graphs can be private, encrypted or shared with collaborators for team use.

Roam Research's strengths are block references and embeds that work across the whole graph, a daily notes workflow that lowers friction, powerful queries and an extension system with Roam Depot and roam/js. Its weaknesses are the lack of a free plan, a higher price than rivals, a learning curve for queries and attributes, and AI that depends mostly on extensions and your own API keys. Logseq offers a similar outliner for free. Obsidian stores Markdown files locally. Tana adds structured supertags and built-in AI. Notion suits shared docs and databases. Choose Roam if you want block-level linking and already think in outlines.

Partly. Roam's changelog lists a feature from October 2026 that generates :q queries with AI from plain language. Beyond that, MentalClone reported in September 2026 that Roam has no built-in AI over your full graph, so users add AI through Roam Depot extensions or MCP connections using their own API keys.
