A quiet place for useful things
Capture an answer, a link, or a half-formed thought. Carbon keeps it close without getting in your way.
Carbon Features
If you enjoy using Carbon, you can show your support.
Designed for active thinking.
You know how you're writing code in Cursor, compiling study notes in Chrome, or bouncing ideas off ChatGPT, and you think, "I'll need this snippet later," but you don't want to stop what you're doing?
Before long, you've got ideas scattered everywhere. A link to research, a homework answer you want to keep, or four follow-up prompts before your current generation is even finished.
Carbon combines the best parts of a clipboard, a to-do list, and a scratchpad into one native utility. It fits seamlessly into modern AI workflows, study sessions, and keyboard-first development pipelines.
Whenever you find something worth keeping, double-tap Shift to capture it. When you're ready, copy it right back into ChatGPT, Claude, or your workspace—and check things off as you go.
Privacy First: Carbon runs completely local. No sync, no tracking, no accounts.
VS Code Integration: VS Code requires Accessibility access enabled to capture active text selections.
Engineered to be simple.
Zero-Focus Fast Paste
Just open Carbon and hit Ctrl+V. Carbon captures your clipboard instantly—no text box selection or focus needed.
Double-Tap Hotkeys
Summon Carbon instantly from anywhere using configurable double-taps (Ctrl, Shift, or Alt).
App-Context Tracking
Capture thoughts from anywhere. Carbon automatically grabs and records the source application of the clipping so you always have context.
Actionable Notifications
Switch destination buckets directly from Windows capture notifications, or double-click the notification to reveal Carbon instantly.
Rich Media & Galleries
Supports single images, multi-image galleries, and drag-and-drop assets. Double-click any image to view it in full screen.
FZF Fuzzy Search
Filter and find your clippings in real time using a blazing fast, terminal-style fuzzy search integration.
Right-Click Drag Scroll
Hold down the right mouse button and drag to pan and scroll through your scratchpad with touch-style inertial physics.
Multiple Buckets
Keep your context separate. Sort your thoughts, urls, and clipboard clippings into distinct workspace buckets.
Designed for Disposal
Carbon acts as a temporary cache. It encourages you to use, copy, and delete scratchpad items, stopping digital note hoarding.
Double-Click Actions
Double-click any item to copy or edit it instantly. Full drag-and-drop support makes reorganizing notes seamless.
Tray & Custom Themes
Minimizes cleanly to the system tray and supports custom light/dark background images with markdown rendering.
Always on Top Mode
Keep Carbon fixed on top of your work while coding, writing, or studying with a quick pinning toggle.
Inspired by macOS Copper
While the original shadcn's Copper provides a beautifully clean, minimalist keyboard-first utility exclusively for Mac, Windows developers were left searching for an equivalent experience.
Carbon brings the same distraction-free aesthetic to Windows, enhanced with native hotkeys and multi-workspace support tailored for the Windows ecosystem.
