Obsidian is arguably the finest personal knowledge base on the planet. But if there is one universal complaint among Obsidian power users, it's quick capture speed.

When inspiration strikes during a meeting or while reading an article, opening Obsidian, waiting for community plugins to initialize, and creating a new daily note file disrupts your flow state.

Many power users turn to floating companion apps, only to discover their notes are trapped inside closed proprietary cloud databases.

Here is how to create a zero-latency quick-capture scratchpad that saves directly into your Obsidian vault in plain .md files.


The Architecture: Float + Obsidian Vault Sync

Unlike note utilities that rely on proprietary cloud synchronizers, Float saves every note as a clean, raw Markdown file on your local disk.

By pointing Float's storage directory to an inbox folder inside your Obsidian vault (for example: ~/Documents/Vault/00_Inbox), you achieve the holy grail of note-taking:

  1. 1.
    Instant Capture in Float (⌥Space): 0ms keystroke response, interactive checkboxes, and live WYSIWYG formatting.
  2. 2.
    Instant Sync in Obsidian: Because Obsidian constantly watches your local file system, changes saved by Float appear instantly in your Obsidian file tree and graph view.
  3. 3.
    Zero Lock-In: You can open your notes in Finder, VS Code, iA Writer, or git version control at any moment.

Step-by-Step Setup Guide

Step 1: Create an Inbox Folder in Obsidian

Inside your Obsidian vault, create a dedicated folder named Float Inbox or 00_Scratchpad.

Step 2: Configure Float's Storage Directory

  1. 1.
    Open Float and press ⌘, (or click the Settings gear icon in the header).
  2. 2.
    Go to the Storage & Files tab.
  3. 3.
    Click "Change..." to open the native macOS folder picker.
  4. 4.
    Select your Float Inbox folder inside your Obsidian vault.
  5. 5.
    Ensure "Auto-save markdown files to disk" is toggled ON.

Step 3: Capture Fleeting Thoughts with ⌥Space

  • Hit ⌥Space while reading a paper or in a Slack huddle.
  • Type / to drop in a quick /todo or code block.
  • When done, hit Esc or ⌥Space to tuck Float away.
  • When you open Obsidian later in the evening, all your scratchpads are already indexed, searchable, and ready to be linked into your permanent notes.

Why Not Just Use Obsidian Daily Notes?

  • Zero Startup Delay: Float is a tiny, native Rust binary that consumes almost zero RAM in the background. It wakes up in under 5 milliseconds.
  • Always on Top: Float floats directly on top of full-screen video calls and PDF readers (⌥P), whereas Obsidian is a full desktop window.
  • Separation of Concerns: Keep your active scratchpad separate from your long-term knowledge graph until you are ready to organize.
