About this app

Atoms Capture gets a thought out of your head and into your Obsidian vault before you lose it.

Open it from the home screen widget, from the quick settings tile, or from a small strip that floats over whatever you are already doing. Type it or say it, then close it. You are back where you were.

Your words arrive in your vault exactly as you wrote them. Nothing is rewritten, shortened, or improved. Each capture becomes a stamped line in one file, Atoms System/Inbox.md. The Atoms plugin for Obsidian picks it up from there.

What you need

Obsidian, a vault stored on this device, and the Atoms plugin. Atoms Capture is a companion, not a notes app. On its own it writes lines to a file. The filing, linking, and resurfacing all happen in the plugin.

Permissions

Files: you pick your vault folder once. Atoms Capture writes to one file inside it.
Microphone: only while you are dictating a capture.
Display over other apps: so the capture strip can open without pulling you out of what you are doing. Optional.
Notifications: so you can see when a capture is open. Optional.

Privacy

Atoms Capture has no internet permission. It has no account, no server, and no analytics. It cannot send your captures anywhere, because it cannot reach the network at all.

Dictation is the one thing worth knowing about. Speech to text is handled by Android's own recognition service, not by us. Depending on your device and your settings, Android may send that audio to Google to transcribe it. If you would rather that never happen, type instead of speaking.
