Obsidian vs Notion: Which Fits a GTD Workflow?

Obsidian vs Notion comes down to this: the better note tool for GTD is the one that gets a loop out of your head in a few seconds, shows you every one of them in a ten-minute weekly review, and lets you walk away in three years with your writing intact. That is the honest test, and it is not the test either vendor’s feature page is designed to pass.

So here is the conclusion, up front. Neither Obsidian nor Notion is a next-action list out of the box, and trying to make either one into your action system is where most GTD rebuilds quietly fail. Obsidian wins retrieval and exit cost. Notion wins structure, sharing and the weekly review view. Most people reading this will end up running both, with next actions somewhere else entirely.

The real difference: plain files on your disk vs blocks in a hosted database

Obsidian is a text editor sitting on a folder. Your notes are Markdown files with a.md extension, stored wherever you put them, openable in TextEdit, Notepad, VS Code or anything else on the machine. Notion stores blocks in its own hosted database, which you reach through the app, the browser or the API. You do not have a folder of Notion files. You have an account.

That single architectural choice decides almost everything else in Obsidian vs Notion. Local files mean search runs on your disk instead of over a network, which is why Obsidian’s search feels instant and Notion’s sometimes does not. Hosted blocks mean genuine multiplayer editing, granular permissions and database relations, none of which a folder of text files can fake. Offline behaviour, mobile cold start, sharing, and what survives when you stop paying all trace back to the same split.

Table stakes, stated plainly so we can move on: both do internal links, nested pages, web clipping, decent iOS and Android apps, and both have shipped AI features. Both are perfectly capable of holding your reference material. The arguments about dark mode and template galleries are not worth your time.

The GTD framing matters more. A notes tool holds reference material and project support material. It is not automatically your list of next actions, and the two jobs have opposite requirements: reference wants depth and richness, context lists want a view you can trust at a glance without reading anything. If you have already worked through our tested picks for a GTD note taking app, this piece goes deeper on the two that generate the most arguments.

Time-to-captured: how fast an idea gets out of your head

Job one: time to captured. Run the test on the vault or workspace you actually have, with the notes, attachments and half-finished databases already in it, not a clean install. A new empty vault is fast in every app ever made.

The test: phone locked in your pocket. Take it out, get a sentence of text saved somewhere you will see it again, and count the steps. If it needs more than a handful of taps and a few seconds, you will stop doing it when you are busy, and the ideas you lose will be the ones you had walking between meetings.

Obsidian has one well-known weakness here: cold start on a large vault. The mobile app indexes your files, and the bigger the vault and the more plugins you load, the longer you stare at the splash screen. The fix is to never open the app to capture. On iOS, build a Shortcut that appends a line to a single Inbox.md (or to today’s daily note) and put it on the lock screen or in the Action button. Text goes in, the app stays closed, the file is waiting when you next sit down. Quick Add plugin does the same job on desktop.

Notion wants a network. Capture into a synced workspace while you are on a train through the Chilterns and you get the spinning state that makes people distrust the inbox entirely. Notion’s quick-add widget and share-sheet extension are genuinely better than opening the full workspace, because they skip the sidebar and drop straight into a database row. Still slower than appending a line to a text file, and still dependent on getting a signal eventually.

Both lose to paper. A card in your back pocket needs no open up, no face scan and no sync, and a biro works in the rain. Keeping a paper capture layer is not an admission that your software failed, it is just acknowledging the real test condition: standing on a platform, hands full, phone locked. Our printable hPDA templates exist for exactly that gap, and there is a longer treatment of the speed problem in the piece on capturing an idea in under five seconds.

One trusted inbox: where open loops land and get processed

Trusted, in GTD terms, means one place. Everything arrives there, you empty it on a schedule, and nothing is hiding in a second workspace you built with enthusiasm in March and abandoned in April.

Notion makes a decent inbox if you keep it to one database with a status property and a relation to projects, then process into filtered views. The failure mode is specific and very common: five dashboards, each with a little inbox section, each holding three stray loops. The workspace looks impressive. Nothing is trusted.

Obsidian’s version is an Inbox.md or a daily notes folder, processed into project notes during the weekly review. The failure mode here is the opposite sort of mess: captures scattered across whichever file happened to be open, with no review trigger to collect them. Obsidian will not nag you. It has no concept of a stale item.

On email and web capture, Notion is ahead if you want things arriving automatically, because it accepts clipped pages, file attachments and forwarded material into the same database, and the API means automations can create rows. Obsidian clips to Markdown cleanly enough, but attachments land as files in your vault and you have to decide where. If your inbox problem started with email in the first place, the rebuild advice in rebuilding a GTD inbox after the Notion Mail shutdown applies regardless of which of these two you pick.

Finding something from half a memory, weeks later

Here is the retrieval test that matters. You remember two words and roughly when. You do not remember the title, the folder, the parent page or what you called the database. Go.

Obsidian is strong here and it is not close. Full-text search runs locally and returns as fast as you can type. Backlinks and unlinked mentions surface connections you never made on purpose. Best of all, because the notes are files, Spotlight, grep, ripgrep and any editor on the machine search the same content without Obsidian running at all. For a reference archive you expect to open in ten years, that is the whole argument.

Notion wins the other half of retrieval, the half Obsidian handles badly. When the thing you remember is a property rather than a phrase, a filtered database view answers in one click: every client project at “awaiting feedback”, every meeting note tagged to one account, everything created last quarter with an empty owner field. Relations and rollups give you structured metadata that no text search can guess at.

Where each one lets you down: Obsidian’s graph view is decoration, not retrieval, and anyone who tells you they find notes by rotating a constellation of dots is performing. Notion’s search degrades as the workspace grows and the nesting deepens, and deeply buried pages in a shared workspace can be genuinely hard to surface when you cannot remember the parent.

Exit cost: what actually survives when you leave

Notion’s export is the quiet trap. Markdown and CSV come out, and the words and images are fine. What does not travel as working structure: relations, rollups, formula outputs, saved database views, synced blocks and comments. You get the writing. You rebuild the system. Everyone underestimates which half took the effort, and the detail is worth reading in full in what a Notion export actually loses.

Obsidian’s exit cost on files is close to zero, because the files were never inside anything. Copy the folder. Done. But there is lock-in people miss, and it is the kind you built yourself: Dataview queries, Tasks plugin syntax, Kanban boards and.canvas files render as intended in Obsidian and as inert text or JSON anywhere else. A vault stuffed with clever queries is portable in the way a car with no engine is drivable.

Plan a move of a few thousand notes like this. The export itself takes minutes. Then budget hours, not minutes, for re-linking internal references, checking image and attachment paths and spot-checking a sample of pages, plus proper rebuild time for the handful of databases that carried relations and rollups. Roughly ten per cent of a mature workspace tends to need hands-on work. Treat that as a planning estimate rather than a measured rule, and scale it up if your workspace leans heavily on formulas. Anyone who has done an Evernote migration with the real costs counted will recognise the shape of it.

Lower your exit cost in whichever tool you choose: keep the structure flat, keep text as text, keep properties few and simple, and schedule an export you have actually opened and looked at. An untested backup is a feeling, not a file.

The daily admin tax: plugin maintenance vs database upkeep

Obsidian’s tax is plugins. Community plugins update on their own schedules, an app update can break one, and the dashboard that only you understand is the dashboard only you can repair. Sync across Mac, Windows, iPhone and iPad needs a decision too: paid Obsidian Sync, iCloud, or a third-party folder service with the conflict files that come with it.

Notion’s tax is upkeep of a different sort. Template drift, databases nobody has written to since last spring, permissions to tidy when a freelancer leaves, and the strong gravitational pull towards building the workspace instead of doing the work. Notion is unusually good at making procrastination look like progress.

The weekly review is the honest test, not the feature list. Sit down and try to see every open loop in one view within ten minutes. No fixing a broken query first. No “I just need to add a status to these”. If you cannot do it, the system has become the project. Notion passes this test more often, because filtered database views are its native strength. Obsidian can match it, but only once you have set up Dataview or Tasks and kept them working, and that maintenance is a real cost you should price in before you commit.

How to choose between Obsidian and Notion (and when to run both)

Choose Obsidian if your material is mostly personal reference and research, you want it fast and offline, and you care about owning the files. Obsidian is free for personal use, with Sync and Publish sold as paid add-ons and a separate commercial licence required for business use. Prices are set in US dollars and change, so confirm on Obsidian’s pricing page before you budget.

Choose Notion if the material is shared, structured and tracked with other people. The free personal plan covers a surprising amount for one person, with paid per-user tiers above it; again, check Notion’s current pricing rather than trusting a figure in any article, including this one.

The hybrid that holds up in practice is boring and it works. Notion for anything a client or colleague opens: shared briefs, trackers, meeting notes. Obsidian on iCloud or Dropbox for the personal reference archive you expect to keep for a decade. Next actions in a dedicated task app, organised by context, which is where OmniFocus, Todoist or Things earn their keep. The reason is simple: a context list has to be trustworthy at a glance, and neither of these two gives you that without you building it. If you want a working example of what a list tool does that a notes tool cannot, the custom perspectives walkthrough shows the difference in practice.

Four questions, then decide:

• How many people touch this material? More than you means Notion.
• Does it need to work on a train with no signal? That means Obsidian.
• Is the data structured, with statuses and relationships that need querying? Notion.
• How fast could you get out with your writing intact? Obsidian, by a wide margin.

Fewer tools, wired together properly, beat a beautiful shelf of software you never open. Pick on the two jobs you do most, not on the comparison table.

Frequently Asked Questions

Is Obsidian or Notion better for GTD?

Neither is a complete GTD system, because neither gives you trustworthy context lists by default. Notion is better for the weekly review and anything shared, since filtered views can show every open loop in one place. Obsidian is better as a personal reference archive, thanks to instant local search and files you own outright.

Can you use Obsidian and Notion together without duplicating work?

Yes, if you split them by audience rather than by topic. Anything a client or colleague opens lives in Notion; your private reference, research and drafts live in the Obsidian vault. The rule that stops duplication is having one home per item and linking to it, instead of copying the text across.

What does Obsidian or Notion cost for a single user in the UK?

Both have a free option that a single user can live on. Obsidian is free for personal use, with Sync and Publish as paid subscriptions and a commercial licence needed for business use; Notion’s free personal plan is generous, with per-user paid tiers above it. Both price in US dollars and revise their tiers, so check each vendor’s pricing page at the time you buy.

How much of a Notion workspace survives an export to Obsidian?

The writing mostly survives. Pages come out as Markdown, databases as CSV, and images and files come with them, though paths often need fixing. Relations, rollups, formula results, saved views, synced blocks and comments do not arrive as working structure, so expect to rebuild those by hand.

Does Obsidian work offline better than Notion?

Yes, and the gap is not subtle. Obsidian reads and writes local files, so editing and search work with no connection at all, and sync catches up later. Notion has improved offline access, but it is still a hosted database at heart, so a flaky connection shows up as the one thing an inbox cannot afford: doubt about whether your capture saved.
