Atom CapThe fastest way to send a screenshot
Capture what's on your screen, annotate in one pass, and drop a shareable link — before anyone asks "can you send that over?"
Capture → annotate → link
Hotkey
⌘ Shift 4
Link copied
Ready to paste in chat
Built for people who share screens all day
first, always
to a shareable link
platforms — Mac & Windows
Capture
Save instantly, stay in flow
Region, window, or full screen from one hotkey — without breaking what you were doing.
Screenshots and short recordings
Grab a still or a quick clip when a static frame isn't enough.
Custom hotkeys
Capture without hunting through menus or leaving your keyboard.
Upload as you capture
Optional cloud upload copies a link the moment you finish.
Reselect before you commit
Drag again if the first crop missed the point.
Annotate
Make the point obvious
Arrows, text, shapes, and blur — enough tools to highlight what matters and hide what shouldn't travel.
Markup in one pass
Call out the exact pixel without opening another editor.
Blur for privacy
Redact names, emails, and tokens before the link leaves your machine.
Crisp exports
Keep annotations sharp at the resolution you captured.
Undo-friendly
Nudge, erase, or start over without losing the capture.
Find
Find what you need, instantly
Every capture stays on disk first. Browse a local gallery that still works when the network doesn't.
Local-first library
Your history lives on your machine — cloud is opt-in.
Search by context
Filter by time, type, or the notes you left on a capture.
Tags that stick
Group related shots for the project you're in.
Quick reopen
Jump back into an annotation without re-capturing.
Capture anywhere.
Find it later.
Available on macOS and Windows today. Your local library stays with you — sync cloud links when you're ready.
Keep your data safe and secure
Share when you want to. Lock things down when you don't.
Password protection
Set a custom password on any capture before you send the link.
Permissions
Choose who can view — "Only me" or "Anyone with the link."
Local-first storage
Captures live on your disk first. Cloud is optional and under your control.
Hashed URLs
Every link is an unguessable hash — no sequential IDs to scrape.
Made for everyday capture
From solo builders to teams — Atom Cap fits into the moments you already share screens.
“I use it about fifteen times a day. Hotkey, annotate, paste the link — done.”
“When English isn't enough, a marked-up screenshot explains the bug faster than a paragraph.”
“Everything stays local until I choose to share it. That's the whole reason we switched.”
