Atom Cap has 3 ways to start capturing easily
Screenshot
Select a region, window, or full screen — then upload and copy the link.
Screen recording
Capture a short clip of any moment, then share instantly from the gallery.
Annotate & share
Mark up screenshots with arrows, text, and blur — then drop a link before you switch windows.
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.”
