The XDA writer who kept nudging Obsidian for months finally figured out what a lot of long-time users already know: Obsidian is a great editor, and a mediocre everything else. It reads Markdown, links notes, and stays out of the way. Sync, PDF handling, diagrams, quick capture, and audio-to-notes are the parts it leaves to other apps. Pick a few good ones and the vault stops being a graveyard.
We looked at eight desktop apps that pair well with Obsidian on Windows, macOS, and Linux. The picks below cover the missing pieces without asking you to abandon plain files or lock into a subscription for something you could do with an open-source tool.
What to look for in an Obsidian companion
- Reads or writes plain Markdown. The vault stays yours.
- Uses the filesystem, not a database. Anything that hides your notes behind SQLite is not a companion.
- No cloud lock-in. If sync only works through the vendor’s servers, look elsewhere.
- Cross-platform. Obsidian runs everywhere. Companions should not force a rebuild on Linux.
- Keyboard-first. Obsidian users lean on shortcuts. Slow, mouse-only tools clash.
- Fits into one job. The best companions do one thing and get out.

The apps
1. Obsidian – The core editor and vault
Obsidian is the reason this list exists. It is a Markdown editor that treats a folder of .md files as a vault, connects them with wiki-style links, and gives you a graph view. Plugins add tables, canvases, kanbans, and everything else, but the core stays plain text on disk. The desktop app is the same on Windows, macOS, and Linux; the mobile app is a smaller version of the same tool.
Where it falls short: Sync costs $4 per month unless you bring your own. Mobile plugin support is slower than desktop. The graph view is prettier than it is useful.
Pricing: Free for personal use. Sync $4/mo. Publish $8/mo. Commercial license $50/user/yr.
Platforms: Windows, macOS, Linux, iOS, Android.
Download: Obsidian, Google Play, App Store
Bottom line: Everyone else on this list assumes you already have Obsidian installed.
2. Syncthing – Best free peer-to-peer vault sync
Syncthing replaces Obsidian Sync. It watches a folder on every device and keeps it identical without a cloud in the middle. Set the vault folder as a shared folder on the desktop, the phone, and the laptop, and every change lands within seconds. Encrypted by default, no accounts, works over LAN or the Internet.
Where it falls short: iOS is an exception; Möbius Sync is a paid Syncthing-compatible client because Apple restricts background sync. Setup takes ten minutes if you have never done it.
Pricing: Free, open source.
Platforms: Windows, macOS, Linux, Android. iOS through Möbius Sync ($9 one-time).
Download: Syncthing
Bottom line: The free upgrade to Obsidian Sync that most power users already run.
3. Zotero – Best reference manager with Markdown export
Zotero captures papers, book chapters, and web sources with one click, then exports them as Markdown notes into the Obsidian vault. The Zotero Better BibTeX and Zotero Integration plugins bridge the two: citation keys resolve, annotations pull across, and each highlight becomes a callout in a note.
Where it falls short: The setup between Zotero, Better BibTeX, and the Obsidian plugin takes an afternoon.
Pricing: Free, open source. 300 MB of Zotero cloud storage is free; more is paid.
Platforms: Windows, macOS, Linux, iOS, Android.
Download: Zotero
Bottom line: The pick if the vault holds research and you want citations to live next to notes.
4. Excalidraw Desktop – Best whiteboard companion
Excalidraw Desktop is a lightweight whiteboard that saves to .excalidraw files. There is also an Obsidian plugin that embeds an Excalidraw canvas inline in a note; the desktop app is what you use for freehand sketching, then drop the file into the vault.
Where it falls short: No real-time multi-user collab in the desktop app; the web version has it.
Pricing: Free, open source.
Platforms: Windows, macOS, Linux.
Download: GitHub Releases
Bottom line: The best hand-drawn diagramming tool that saves to a vault-friendly format.
5. Zettlr – Best academic editor for the same vault
Zettlr reads the same Markdown files as Obsidian and adds the academic pieces Obsidian omits: full CSL citation styles, Pandoc export to Word and LaTeX, and a proper writing mode with word-count goals. Open the vault in both apps and they respect each other’s files.
Where it falls short: The Zettlr and Obsidian graph systems do not talk. Wiki-links from Obsidian resolve; queries and dataviews do not.
Pricing: Free, open source.
Platforms: Windows, macOS, Linux.
Download: Zettlr
Bottom line: The right editor for the writing weeks when Obsidian’s plugin-driven layout gets in the way.
6. Raycast – Best quick-capture launcher (macOS)
Raycast captures a note into Obsidian in one shortcut. Hit the launcher, type the note, hit enter, and it lands in a designated inbox folder in the vault. Plugins add per-vault targets, template selection, and calendar snippets. On Windows, Flow Launcher does the same thing.
Where it falls short: Raycast Pro is where the AI actions live; the free tier is enough for capture.
Pricing: Free. Pro $8/mo.
Platforms: macOS. Flow Launcher covers Windows for free.
Download: Raycast, Flow Launcher for Windows
Bottom line: The single upgrade that turns Obsidian from “app I remember to open” into “always one keystroke away.”
7. Snipd – Best podcast highlights to notes
Snipd is a podcast player that lets you tap a button when you hear something worth remembering. Later, on the desktop, it exports each highlight (with a Whisper transcription and a timestamped audio clip) into a Markdown note inside the vault.
Where it falls short: Podcast-only. Not a general audio-to-notes tool.
Pricing: Free with generous limits. Pro $7/mo removes the export cap.
Platforms: Windows, macOS, iOS, Android.
Download: Snipd, Google Play, App Store
Bottom line: The clean bridge from “podcast I liked” to “note I can search.”
8. OrgPad – Best canvas that saves back to files
OrgPad is a non-linear canvas for mind-mapping, planning, and clustering ideas. Export nodes as Markdown into the vault, then rewire them in OrgPad when the shape of the project changes.
Where it falls short: Not open source. Free tier caps active nodes; the paid tier lifts that.
Pricing: Free. Pro from about $5/mo.
Platforms: Windows, macOS, Linux, web, iOS, Android.
Download: OrgPad
Bottom line: The canvas tool for anyone who finds Obsidian’s built-in Canvas too flat.
How to pick the right one
- The one-line answer: install Syncthing for sync, Raycast (macOS) or Flow Launcher (Windows) for capture, and Excalidraw for sketches. That’s 80 percent of the boost.
- For a research vault: add Zotero and its Obsidian bridge.
- For serious writing: Zettlr on top of the same vault.
- For podcast learners: Snipd.
- For visual planners: OrgPad.
FAQ
What is the best free Obsidian sync?
Syncthing on desktop and Android. On iOS, Möbius Sync is a paid app that reads Syncthing folders.
Do I need a plugin to embed Excalidraw in Obsidian?
The Obsidian Excalidraw plugin embeds a canvas inline. The desktop app is only needed for standalone sketches.
Can Zotero and Obsidian share the same folder?
Zotero keeps its library separately. The bridge exports notes and annotations into the vault, but Zotero’s own database lives in Zotero.
Does Snipd upload my podcast library?
Snipd pulls podcasts from public RSS feeds like any player. Highlights and transcripts sync to your account; audio itself does not upload.
Is Raycast worth paying for?
For Obsidian capture, no. The free tier covers it. Pay for Pro if you also use the AI features and the cloud sync.
