What Wisp is

Wisp is a free, open-source game clip recorder for Windows 10 and Windows 11. It keeps a screen-and-audio buffer continuously or while a game is running, then saves that buffer when you press a hotkey or kill detection is enabled. A clip can be created in under a second, and pressing the hotkey again while a clip is fresh can chain another segment to it 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 samples their on-screen kill confirmation UI. Wisp captures with Windows Graphics Capture, with Desktop Duplication and GDI as alternatives, and supports hardware encoding on NVIDIA, AMD, and Intel GPUs. System audio and microphone input can be mixed independently, while voice chat apps such as Discord can be isolated on a separate track. An optional voice trigger runs a bundled speech model locally without internet access.

Its clip browser shows thumbnails, duration, and file size, and supports playback, search, sorting, renaming, and deletion. Plugins can add themes, overlays, timeline markers, export video layers, clip actions, and tray menu items. The maker says Wisp has no ads, account, or telemetry; its GitHub update check is the only network connection and can be disabled. Wisp is licensed under GNU GPL version 3.0 or later.

Who it suits

Wisp suits Windows gamers who want to save recent gameplay clips through a hotkey or supported kill detection, with separate control over system audio and microphone input. It may also suit users who want local voice triggering, plugins, or an open-source recorder.
