I accidentally deleted my reply so here it is again!
I’m finding Obsidian a great Devonthink replacement.
I have the ‘all file type’ sync option enabled, on desktop and mobile, and use attachments in Obsidian and files in assets folders. I’ve mainly used PDFs and images so far.
It took a while to create notes for some of the files, but i did this in a few days. I can access them on mobile and desktop and all my attachments are in folders on my iCloud, which I much prefer to proprietary databases.
I had attachments in both Devonthink (imported) and Craft before and finding attachments became a chore. I’d often forget which app I’d put them in and had to deal with the apps to search and then export the attachments.
Now, I can use Alfred to search for and in files, and I find this much quicker. Having the notes as plain text files means I can also use apps and scripts to do quick batch processing, for example find and replace and renaming. I’ve used this a lot to prune and rename my notes and attachments.
The biggest benefit is the linking of all my notes and ideas in one place. I can see links between my notes, journal, daily notes, meetings and projects and it helps a lot. I’m finding this really helps in generating ideas and local graphs are really helping me with research and brainstorming.
Obsidian is not a web-based service. Your data are in files in your Mac’s file system and/or in the iPhone or iPad’s local files. Obsidian can sync between the two. If you want to share information in Obsidian on the web, there is an optional, fee-based, add-on service Obsidian Publish. But, that is view-only.
Install Obsidian on iOS/iPadOS from the App Store.
On your Mac, look for Obsidian’s iCloud Drive app container (an app-specific folder created in your iCloud Drive directory). It will have the Obsidian logo.
Drag and drop your Vault folder into the aforementioned iCloud Drive/Obsidian folder.
On iPhone/iCloud, wait for it to sync. This part can be a little tricky. Obsidian needs your entire folder structure available to work: it uses the contents of every file inside to drive its functions. Unfortunately, Apple’s a bit paternalistic about whether or not iCloud Drive files should be downloaded. So, you need to trigger the download by launching Obsidian and opening the vault. That might take a little while, especially if the vault is big, because Obsidian is forcing iCloud Drive to download all of the files inside it. While this is happening, you can actually check progress by going to the Files app and looking at the vault in iCloud Drive/Obsidian. If it seems to get stuck, you can relaunch Obsidian to give iCloud Drive some encouragement.
Aside: The most frustrating thing about this process is that it’s really a bunch of workarounds that address Apple’s insistence that iOS/iPadOS not be a real operating system. Far as I can tell, users on Android had a much easier time because the file system is designed to be a lot easier to work with in these kinds of situations…
It looks like @ryanjamurphy posted before I did. He is far more expert than I so follow his advice if anything I have below contradicts his. @ryanjamurphy if I have a mistake please correct it. I don’t want to steer @rbanks88 in the wrong direction.
You are not alone in being confused. The explanation of how to setup sync is, to be kind, less than clear. In fact, there are several threads on the Obsidian forum asking the same questions. So, you are in good company. You may want to check those out.
First, you may find these two YouTube videos helpful. I encourage you to take the time to watch them carefully.
Second,
Follow the above posted directions given exactly. It is a strange way to setup sync but it does work.
Here are a couple of tips based on how I set my sync up, which is working perfectly.
Make sure your Obsidian vaults/folders are backed up
Create a NEW Folder on your Mac desktop with all of your Obsidian folders/files copied (not moved) to it. You will now have two identical Obsidian folders: your original and this new one.
On your Mac, delete the original folder to the trash, BUT JUST IN CASE, DON’T DELETE THE TRASH BIN, that way you can recover it if needed.
Now, go to your iPad and follow the directions. Once the new Obsidian vault in created on the iPad (I presume in iCloud—which is where I have mine), go to your Mac, copy all of the Obsidian folders/files you created new on your desktop and paste them into the NEW OBSIDIAN FOLDER you created on the iPad. Once this is done, you should have the Obsidian vaults/folders you want to use from this point forward.
Open Obsidian on the IPad and open the folder you created as a vault.
Create a test document on both the iPad and the Mac to make sure they sync.
If they sync, do a another backup then delete the folder on your desktop and feel free to empty your trash.
Here is how this looks in iCloud and on both my IPad and MBP
Talk to me like I’m 5. I did a quick scan of Obsidian. If I’m using iCloud to house my Obsidian vault, does it cost the monthly fee to sync between my laptop and iOS devices?
Hopefully not too off-topic, but how is indexing in DT working for you? I keep wanting to switch, but I always seem to run into some issue (e.g., file suddenly missing, requiring a re-index).
If DT would add another local sync option (other than Bonjour) so it would work over VPN, I’d be set. Alas…
I changed from indexing to importing all of my research into DEVONthink. Then, once a month, I export my research into an archive folder in Finder, which is accessible via an Obsidian vault. This creates duplication but I delete the older archive files so it is not a substantial hit on my storage capacity. I find that importing works better for capturing research material and I avoid any syncing issues related to indexing.
I index my Obisdian vault in DevonThink and haven’t had any problems, is that what you’re asking?
Re: VPNs they’ve done some work on this, if your sync isn’t working it’s worth posting in their forum with the name of your VPN provider so they can test it. Might also be worth scanning their forum as there has been some chat the last couple of months about which providers aren’t working.
