A local-first desktop workspace keeps a working copy of your material on your computer rather than making every action depend on a remote page. That does not automatically mean every feature works offline, nothing is synced or the service cannot read server-held data. Compare the storage model, the working surface and the boundaries of connected features separately.

For documents and research on a shared task canvas, [download Plexii free](https://plexiidesk.com/download) for Mac or Windows. If your main requirement is a collection of linked text notes, a local notes application may be a better starting point than a full workspace.

## Compare documented models, not privacy slogans

These facts were checked on 7 November 2026 against the primary pages linked in the table. “Local-first” is used here as a practical storage question, not a certification applied equally to every product.

| Product | Mac and Windows evidence | Local working model documented | Connected functions documented |
|---|---|---|---|
| Obsidian | Both listed on [downloads](https://obsidian.md/download) | Notes stored on-device; offline access; Markdown files | Sync with end-to-end encryption; Publish for web pages, described on its [product page](https://obsidian.md) |
| Joplin | Windows and macOS listed on its [product page](https://joplinapp.org) | Open-source note-taking app; notes saved to an open format | Synchronisation through services including Joplin Cloud, Dropbox and OneDrive; documentation describes E2EE |
| Plexii | Mac and Windows specified in [pricing](https://plexiidesk.com/pricing) | Workspace on-device first; product documentation says it works offline | Account sync, sharing and collaboration; sync encrypted in transit but not end-to-end encrypted, explained in [privacy](https://plexiidesk.com/privacy) |

Joplin's homepage describes its synchronisation and encryption, but the exact offline operations and encryption setup should be checked for your chosen configuration. The table does not mark every function as available without a connection.

## When a local workspace is the relevant category

Plexii's [files and local-first product section](https://plexiidesk.com/product#files) describes workspace storage and account-backed sync. Its desk adds a working surface: documents, tables, notes and live browser windows arranged around a task.

That combination is worth assessing when the work crosses file types. A proposal with a cost sheet and reference pages is a different use case from a personal collection of text notes. The [report workspace example](https://plexiidesk.com/for/neurodivergent-visual-thinkers) shows that distinction without requiring you to redesign your whole filing system.

Start with non-sensitive sample material until you have checked data flows against your requirements. The fact that a working copy lives on your computer is only the beginning of that review.

## First choose the kind of work you need to hold

A notes application, a task manager and a workspace can all store information locally while presenting very different working surfaces. Decide which surface you need before comparing storage claims.

Obsidian's documented links, graph and Canvas are relevant to connected reference notes and visual relationships. Joplin documents multimedia notes, a web clipper and several synchronisation options. Plexii documents a desk with office tools and research alongside the task.

Those are positive descriptions of what each product offers, not proof that the others lack a function. Avoid choosing from a checklist built on undocumented absences. A missing item on a homepage is not evidence that a feature does not exist.

Bring a representative piece of work to the comparison: one report, one reference collection or one recurring checklist. Ask which arrangement lets you make and retrieve that work without unnecessary setup.

## Separate local storage from offline behaviour

A document can be stored locally while its linked website still needs the internet. An app can launch offline while a sign-in, synchronisation or AI service cannot complete. A folder can contain placeholders rather than downloaded file contents.

For each product, test the operations you actually require. Can you open the file, edit it, save it, close the app and reopen the saved change? Are images and attachments present? Do you know which actions will wait for a connection?

Use sample work and understand any first-run account requirements before disconnecting. Plexii's product page says you create an account on first opening and that the workspace works offline. That is not a promise that initial setup, websites, meetings or cloud AI can run without connectivity.

Our [working offline guide](https://plexiidesk.com/blog/working-offline) is the procedural companion to this comparison. [Local-first explained](https://plexiidesk.com/blog/local-first-explained) owns the broader definition and terminology.

## Separate sync from backup

Sync copies a working state across devices or a service. Backup keeps a recoverable earlier copy according to some retention and restoration arrangement. They may be offered together, but they are not the same promise.

If a deletion syncs, another device can faithfully receive the deletion. Before relying on a product for important work, find out how you restore an earlier state, what is included and whether you have tested that restoration.

For a work laptop and home computer, test a harmless change and a harmless deletion. Observe which device becomes authoritative, how conflicts are presented and what recovery is available. Do not experiment on the only copy of a live client document.

Keep independent copies in whatever way your organisation permits. Export is useful, but an export you have never opened elsewhere is an untested assumption about portability.

## Encryption needs a more exact question

“Encrypted” can describe different boundaries. Encryption in transit protects the connection. End-to-end encryption concerns who can decrypt the content at the service end. Local device protection concerns the machine and files themselves.

Obsidian's product page describes end-to-end encrypted Sync. Joplin's page describes E2EE for notes and links to its encryption information. Read the configuration details rather than assuming every connection starts with the same settings.

Plexii is explicit that account sync is encrypted in transit and is not end-to-end encrypted. Its privacy page says server-held data for sync and connected features can be read by the server so those features work. Its master-password vault is a separate protection, not a description of all synced material.

If your organisation requires end-to-end encryption for particular material, that requirement should guide the decision. A broader workspace feature set does not cancel a storage requirement.

## Understand what connected AI changes

Local storage does not by itself imply local inference. A document can stay on disk until you choose a function that sends a prompt or context to a service.

Plexii's [privacy policy](https://plexiidesk.com/privacy) distinguishes managed AI requests, which route through its server, from requests using your own Anthropic key, which go directly from the computer to Anthropic. Either is a network data flow, not a claim that the model runs entirely on your computer.

This comparison does not recommend a particular key or provider configuration. Check the current provider, plan and settings before enabling AI on sensitive material. If you do not need AI for the task, evaluate the underlying storage and editing experience without it first.

The companion post [What leaves your computer](https://plexiidesk.com/blog/what-leaves-your-computer) helps frame those questions. Read the live privacy documentation as the primary source where wording or settings have changed.

## A practical Mac-and-Windows evaluation

Use a small fictional project that resembles your real work. For a report, include a document, a table, an image, a reference note and a web link. For a notes system, include linked text and an attachment you can search for later.

1. Install the supported build and complete ordinary setup.
2. Create the sample work and confirm where it is saved.
3. Close and reopen the app to test persistence.
4. Test the offline actions you need, without assuming connected ones will work.
5. If using sync, make a small change on a second device and check the result.
6. Export or copy the allowed material and verify you can read it independently.
7. Record limitations before moving a real project.

This is a test of your required workflow, not a speed benchmark. Record a failed operation precisely enough to check whether it is a limitation, setup issue or unsupported file type.

## When not to move into a larger workspace

If your notes system already makes reference material easy to retrieve, a full workspace may add work without solving a problem. Keep the smaller arrangement if it suits the task.

If colleagues must edit in a specific system of record, do not create a competing authoritative copy just to use a new canvas. A workspace can hold context and links while the approved file remains where the team expects it.

Similarly, if your employer's device or data policies rule out an installation or server flow, the correct response is to respect that boundary. “Local-first” is not an exemption from policy.

For Plexii, the personal tier is free forever, Pro is US$12 per month or US$120 per year, and a 14-day Team trial is documented on [pricing](https://plexiidesk.com/pricing). Use the trial to test a known need, not as a reason to migrate material before checking the requirements.

## Common questions

**Does local-first mean cloud-free?** No. A product can keep a local working copy and still synchronise data or use servers for sharing, communication and AI. Read the specific data-flow documentation.

**Do all three products run on Mac and Windows?** Their linked current product or download pages list both platforms. Check supported operating-system versions and hardware before installation; platform availability is not identical to feature parity.

**Is Plexii sync end-to-end encrypted?** No. Plexii's privacy and product pages say sync is encrypted in transit but not end-to-end encrypted. The local master-password vault is a different boundary.

**Can I assume a web page on a local canvas works offline?** No. Locally saved work and an embedded live website have different connection needs. Save authorised reference material separately where offline access is essential.

**Is sync an adequate backup?** Not by itself. Check recovery history, retention and restoration. A synced mistake may propagate, so test an independent recovery route with harmless sample material.

**Which local-first app should I choose?** Match the documented working surface and data boundaries to your task. Linked notes, clipped research and full document workspaces are distinct needs; this article does not declare a universal winner.
