Wisp

What Wisp is

Wisp is a free, open-source Windows game clip recorder for saving recent screen and audio. It keeps a buffer continuously or while a game is running, then can save that buffer after a hotkey press or kill detection. A second press while a clip is fresh can join clips together, with a marker at each press. Kill detection uses official local APIs for League of Legends and CS2; detection for Valorant and Overwatch 2 is experimental and reads on-screen kill confirmations. Wisp captures with Windows Graphics Capture, with Desktop Duplication and GDI as fallbacks, and uses hardware encoding on NVIDIA, AMD, or Intel GPUs when available. System sound and microphone can be mixed independently, and voice chat such as Discord can have its own track. An optional voice trigger runs a bundled speech model locally. The clip browser shows thumbnails, duration, and file size, and supports playback, search, sorting, renaming, and deletion. Plugins can add themes, overlays, timeline markers, export layers, clip actions, and tray menu items. Wisp runs on Windows 10 version 2004 or newer and is licensed under GNU GPL version 3.0 or later.
