How Does Note Sync Work in Obsidian and Memory Chat? Which One Is Easier to Use?

One of the first questions new Obsidian users often ask after a few days is:

• How can I access the same notes on multiple devices?

It sounds like a simple question, but the answer isn't.

Unlike most note-taking apps, Obsidian’s synchronization is not built in and ready to use by default. Instead, it's a separate decision you need to make, with multiple options available—each with its own requirements and trade-offs.

Why Doesn't Obsidian Include Built-In Sync?

Obsidian follows a clear philosophy: your notes are standard Markdown files stored locally on your device, and no external server stores or reads them by default.

This approach gives Obsidian some of its greatest strengths:

• Complete ownership of your data
• Your notes can be opened with any Markdown or text editor
• You're not locked into a specific company or cloud service

However, this design also means that synchronization is not enabled by default in the free version, and users must choose how they want to sync their notes.

1️⃣ Obsidian Sync

Obsidian offers a paid service called Obsidian Sync, designed specifically for the app.

It includes:

• 🔐 End-to-end encryption, ensuring that even the Obsidian team cannot read your notes.
• 🗂️ Complete synchronization, including folders, files, attachments, and images.
• 🕓 Version history, allowing you to restore previous versions of your notes.
• ⚙️ Selective sync, so you can exclude specific folders if needed.

The important point is that Obsidian Sync is a separate paid subscription, and even after subscribing, you still need to configure your account and manually connect each device.

2️⃣ Using Cloud Storage Services

To avoid paying for Obsidian Sync, many users store their Vault inside cloud services such as iCloud Drive, Google Drive, OneDrive, or Dropbox.

Although this solution is often free, it comes with several challenges:

• Upload delays, since these services aren't designed for apps that constantly read and write many small files.
• Sync conflicts when editing the same file across multiple devices without reliable internet access.
• Some platforms require additional setup or third-party apps to access cloud folders correctly.

Common Challenges Reported by Users

Discussions within the Obsidian community frequently highlight the same concerns:

• No built-in free synchronization across devices.
• Every synchronization method requires manual setup and configuration.
• File conflicts may occur, especially when working offline on multiple devices.
• The syncing experience can vary across operating systems, including Windows, macOS, iOS, and Android.

These aren't necessarily flaws—they're natural consequences of Obsidian's local-first design philosophy. However, they're important considerations for anyone planning to use Obsidian across multiple devices.

How Does Memory Chat Handle Synchronization?

Memory Chat follows a completely different approach.

Instead of treating synchronization as an optional feature, it is built into the app from the very beginning.

• 💾 Whenever you add a note, task, or budget entry, it is immediately saved to a local database on your device, whether you're online or offline.

• ☁️ As soon as an internet connection becomes available, your data automatically syncs in the background to the Memory Chat server and then to your other connected devices.

• 🔑 There's no need to configure cloud storage services, connect folders, or install additional tools. Simply sign in with your account, and your devices stay connected automatically.

The result:

Because synchronization and conflict resolution are handled directly by the application, duplicate or conflicting versions of the same note are much less likely to occur.

What About Security?

Synchronization alone isn't enough without proper data protection.

That's why everything you add to Memory Chat—including notes, photos, and files—is fully encrypted.

• Every note, image, and file is encrypted before being synchronized.
• The encryption key is not stored on Memory Chat's servers. Instead, it is securely stored in your own Google Drive or iCloud account, meaning only you can access it.
• As a result, your information stays protected while syncing across all your devices, without exposing it to third parties.

What Changes Between the Plans?

Synchronization is included in every Memory Chat plan.

The only difference is the number of devices you can connect simultaneously:

• 🟢 Free Plan: Sync across up to 2 devices.
• 🔵 Higher Plans: Connect up to 4 or 8 devices, depending on your subscription.

Synchronization itself is available from your very first use—the plans simply determine how many devices you can connect.

Which Approach Is Right for You?

With Obsidian, you'll need to make additional decisions:

• How will you synchronize your notes?
• Will you pay for Obsidian Sync or use a third-party cloud service?
• How will you manage multiple devices?

If you mainly use a single device or enjoy customizing every aspect of your workflow, these extra steps may not be a problem.

With Memory Chat, the process is much simpler.

• You create a note or add a task, and the app handles everything else.
• Your data is saved locally first, then synchronized automatically whenever an internet connection is available—without complicated setup or external services.

In other words:

• With Obsidian, you manage your note synchronization yourself.
• With Memory Chat, the app handles it for you, so you can focus on your ideas instead.

If you're looking for a simple experience that works right from the start, Memory Chat is likely the more convenient choice for everyday note-taking.
