Notion and Obsidian are the two apps people name first when they start a second brain. They solve the problem in opposite ways. Notion keeps everything in a cloud workspace built from pages and databases. Obsidian keeps every note as a plain text file on your own device. This guide compares both on the points that decide a second brain, with prices checked on each vendor's own pricing page on 2026-10-19, and shows when a third option, Taskade, is the better fit.
TL;DR: Pick Obsidian if you want private notes stored as files on your device, free, with plugins. Pick Notion if you want shared docs and databases for a team, with full AI on its Business plan ($20 per member per month billed yearly). Pick Taskade if you want notes, tasks, AI agents and automations in one shared workspace. Compare Taskade plans.

Which Is Better for a Second Brain?
Obsidian is the better second brain for one person who wants to own the notes for decades. The files are plain Markdown, the app is free, and links build a web of ideas. Notion is better when the second brain is shared, or when it is really a set of databases for projects, reading lists and contacts.
The term "second brain" comes from Tiago Forte's Building a Second Brain method: capture, organize, distill and express. Each app supports those four steps in a different way. See the second brain explainer on our wiki for the method itself, and the PARA method for the folder system most second brains use.
| Second brain step | Notion | Obsidian | Taskade |
|---|---|---|---|
| Capture | Web clipper, mobile app, forms | Quick note, daily note, plugins | Mobile app, paste, import, automations |
| Organize | Databases, properties, teamspaces | Folders, tags, links | Projects, folders, tags, backlinks |
| Distill | Highlights, Notion AI summaries | Manual highlights, plugins | AI agents that summarize your projects |
| Express | Pages, sites, shared docs | Obsidian Publish ($8/site/mo yearly) | Share links, apps built with Taskade Genesis |
What Is Notion?
Notion is a cloud workspace where every page is built from blocks, and any page can hold a database. Teams use it for wikis, docs, project boards and lightweight CRMs. It works as a second brain when you want structure: a reading list database, a project database, and notes linked to both.
Notion workspace with nested pages
Two real strengths stand out. First, databases: one table can show as a board, a calendar or a gallery, and properties such as status, owner and due date make notes searchable by more than text. Second, teamwork: several people edit the same page at once, with comments, mentions and page permissions.
Notion blocks: each part of a page is a block you can drag
The trade-off is setup time. A blank Notion workspace asks you to design the system yourself, and large databases can feel slow on a big workspace. Notion's Free plan gives unlimited blocks to one person, but blocks are limited once you add 2 or more members, and uploads are capped at 5 MB each. See our Notion alternatives list if the setup feels heavy.
What Is Obsidian?
Obsidian is a free Markdown editor that stores each note as a .md file inside a folder called a vault on your own device. Links between notes build a knowledge graph, and Graph view draws it. Obsidian is the most popular choice for a private, long-term second brain.
Obsidian has three strengths that Notion cannot copy. The notes are yours: plain files that open in any text editor, with no export step. The app is fast, because it reads local files with no network round trip. And the community plugin library adds almost anything, from task lists to kanban boards to AI chat.
Obsidian Graph view
Since 2025, Obsidian Bases adds table and card views over your notes' properties, which used to need the Dataview plugin. Some Obsidian users also point an AI coding agent at their vault, with a guide file at the vault root that tells the agent how to read and write notes. Read the history of Obsidian for the full timeline. The trade-off: no real-time co-editing, and many features depend on plugins that volunteers maintain.
Storage and Privacy
Obsidian stores notes as local Markdown files, so nothing leaves your device unless you turn on Obsidian Sync or a third-party sync tool. Notion stores every page on its own servers and syncs it to every device. Taskade also stores projects in its cloud. For a private journal or sensitive research, Obsidian's local files give the most control.
| Notion | Obsidian | Taskade | |
|---|---|---|---|
| Data location | Notion servers | Your device | Taskade servers |
| File format | Notion blocks, export to Markdown, CSV, PDF | Plain Markdown | Projects, export to Markdown, CSV, PDF, text |
| Account needed | Yes | No sign-up required | Yes |
| Sync | Built in | Sync add-on or your own (iCloud, Git) | Built in |
Local files also make backups simple: copy the vault folder. With a cloud tool, you rely on the vendor's export and version history. Obsidian Sync adds end-to-end encrypted sync and version history if you want both.
Linking and Graph View
Obsidian has the strongest linking of the three. Type [[ to link any note, see every backlink in a side panel, and open Graph view to explore clusters of ideas. Notion supports page links, backlinks and linked databases, but it has no graph. Taskade links projects with @ backlinks and shows connections on a workspace memory graph.
In Taskade, type @ and part of a project title to insert a backlink. The memory graph then shows how projects, agents and automations connect. For a Zettelkasten-style web of atomic notes, Obsidian is still the best tool. For a second brain that links notes to the work they drive, Taskade and Notion fit better. Our guide to connected thinking explains why links matter more than folders.
AI Features in 2026
Notion has the most built-in AI of the two: Free and Plus include a trial of Notion AI, and full Notion AI comes with the Business plan at $20 per member per month billed yearly ($24 monthly). Obsidian sells no AI plan. Its AI comes from community plugins or outside tools that read your files. Taskade includes AI agents that answer from your projects.
| AI need | Notion | Obsidian | Taskade |
|---|---|---|---|
| Write and summarize | Notion AI (full on Business) | Community plugins | AI agents and Taskade EVE |
| Answer from your notes | Notion AI search on Business | Plugins or outside tools | Agents trained on your projects |
| Run multi-step work | Custom Agents, $10 per 1,000 Notion credits | Not built in | Agents with tools, plus automations |
| Models | Notion's choice | Your plugin's choice | Frontier models from top AI labs |
A Taskade agent can use your projects as knowledge, so it answers with your own notes, not only the open web. On Taskade's Free plan, you earn free AI credits through referrals and invites, and you can upgrade any time. Our guide to building a second brain with AI walks through the workflow, and the AI second brain tools list compares more apps.
Teamwork
Notion is the clear winner over Obsidian for teams. Several people can edit one page at the same time, leave comments, and share a teamspace with permissions. Obsidian is a single-user app: Sync can share a vault, but two people cannot co-edit a note live. Taskade also supports real-time co-editing, with chat, tasks and assignees in each project.
If your second brain is really a team knowledge base, see our knowledge base apps guide. A ready-made team wiki portal kit shows what a shared second brain looks like in Taskade.
Pricing Compared
Obsidian is the cheapest: the app is free, and you pay only for Sync ($4 per user per month billed annually) or Publish ($8 per site per month billed annually). Notion is free for one person, and Plus costs $10 per member per month billed yearly. Taskade is free with limits, and Pro costs $10 per month billed annually.
| Plan | Notion | Obsidian | Taskade |
|---|---|---|---|
| Free | Unlimited blocks for 1 person, 5 MB uploads, AI trial | Free without limits | Unlimited projects, 2 members, 3 Taskade Genesis apps, 1 agent |
| First paid tier | Plus $10/member/mo yearly, $12 monthly | Sync $4/user/mo yearly, $5 monthly | Pro $10/mo billed annually |
| Next tier | Business $20/member/mo yearly, $24 monthly | Publish $8/site/mo yearly, $10 monthly | Business $25/mo billed annually |
| Optional | Custom Agents, $10 per 1,000 credits | Commercial license $50/user/yr, Catalyst $25 one time | Credit packs |
All prices checked on notion.com/pricing, obsidian.md/pricing and taskade.com/pricing on 2026-10-19. A team of 5 on Notion Plus pays $50 a month billed yearly. Five Obsidian users who each want Sync pay $20 a month billed yearly. Check the Free plan limits before you move a team.
Notion vs Obsidian by Use Case
The right pick depends on the job the second brain does. Obsidian wins for solo research, writing and long-term personal notes. Notion wins for shared wikis, student group projects and anything that needs a database. Taskade wins when notes must turn into tasks, apps or automated work for a team. The table maps common jobs to the best fit.
| Use case | Best fit | Why |
|---|---|---|
| Personal Zettelkasten or reading notes | Obsidian | Local files, wiki links, Graph view |
| Student notes and class wiki | Notion | Free for 1 person, pages and databases |
| Writing a book or long essays | Obsidian | Fast plain-text editor, no lock-in |
| Team wiki and onboarding docs | Notion or Taskade | Real-time editing, permissions, comments |
| Meeting notes that become tasks | Taskade | Notes and assigned tasks in one project |
| A research hub an AI agent can answer from | Taskade | Agents use your projects as knowledge |
| Developer notes next to code | Obsidian | Markdown files you can keep in Git |
Students can start on any of the three for free. Obsidian keeps private notes for life, Notion's Free plan covers one person, and Taskade's Free plan covers 2 members. For a step-by-step setup, follow our guide to building a second brain with AI.
When Taskade Is the Better Third Option
Taskade is the better pick when your second brain must do work, not only store it. Notes, tasks, AI agents and automations live in one shared workspace, so a note can turn into a task, an agent can answer from it, and an automation can send it to another app. That is a different job from Notion's databases or Obsidian's local files.
Here is what Taskade adds, in plain terms:
- One prompt builds a live app. Describe a reading tracker, a client portal or a research dashboard, and Taskade Genesis builds it with its own database. See the Taskade Genesis wiki for how it works.
- AI agents with knowledge and tools. Agents answer from your projects, search the web and work inside an app or on their own.
- Automations with 100+ integrations. Automations use triggers to pull events in and actions to push data out.
- Workspace DNA. Projects are the memory, agents are the intelligence, and automations are the execution.
- Clone a kit. Start from a ready-made app in the app gallery, such as a note tiles kit, and share it with a link. A custom domain needs Pro and up.
- Taskade EVE builds in chat. Ask Taskade EVE to build or change the app, and it edits it for you.
Taskade's Free plan has unlimited projects, 2 members, 3 apps, 1 agent and no starting AI credits. Pro is $10 per month billed annually. Our Notion vs Taskade comparison goes deeper on the team side.
How to Move Your Notes
Moving between these three apps is short, because all three read Markdown. Notion exports pages as Markdown and CSV. Obsidian notes are already Markdown files. Taskade imports both through the Import dialog.
- From Notion: open the page menu, choose Export, pick Markdown & CSV, and unzip the file. To export everything, use Settings, then Export all workspace content. Full steps: Import from Notion.
- From Obsidian: open File, then Open Vault, and reveal the vault folder. The
.mdfiles are ready to import as they are. Full steps: Import from Obsidian. - Into Taskade: click the arrow next to New Project, choose Import, and drag the
.mdfiles into the Import with AI tab. Use the Import CSV tab for Notion databases. - Into Obsidian: put the Notion Markdown files into a folder and open it as a vault.
Check internal links after a move. Notion page links and Obsidian [[wiki links]] do not always map one to one.
Limitations: When Taskade Is Not the Right Fit
Taskade is not the right fit for every second brain. If you want notes stored only as local files that no cloud service touches, Obsidian is the better choice. If you live in deep relational databases, with rollups and formulas across many tables, Notion's database engine goes further than Taskade's tables.
Taskade needs a live internet connection and has no offline editing mode, so Obsidian or Notion suit notes you write on a plane. Taskade is also a poor fit if you want a large plugin library to shape the editor, which is Obsidian's biggest strength. And Taskade's Free plan starts with no AI credits, so heavy AI use on Free needs free AI credits that you earn, or a paid plan. If any of those points matter most, start with the tool that fits them, and see our Obsidian alternatives list for more local-first options.
