Type // in any Mac app. The thought files itself. You keep writing.
Every time you switch apps to jot down a task, calculate a sum, or save a snippet, you create a second task: returning to the thought you interrupted. Researchers call the lingering mental cost “attention residue.”
Doubleslash exists to eliminate that tax. By bringing capture to the caret, you offload thoughts at the speed of typing, without ever breaking your flow state.
If a destination cannot take the line — a missing Obsidian vault, a Logseq graph, a Slack token, or a macOS permission — Doubleslash opens a dialog with the reason. The button takes you to Settings and highlights the field that needs a path or a grant. The line stays in the local recovery log. When a capture lands, the confirmation names the file, list, or channel, and the menu can reveal it. Up to three unfinished lines stay in the menu bar. A line that starts with “when” comes back when that app or document returns.
* The concept of attention residue was coined by Sophie Leroy in 2009.
Same caret-anchored HUD in Mail, Obsidian, Notes, TextEdit — and everywhere else you type.

Hi Sarah,
Trigger matching, local history, notes, timers, and calculator data stay on your Mac. The app does not send product analytics. Accessibility and Input Monitoring detect // and place the HUD at your caret; document text is not uploaded for core targets.
