Splice

Get started in 5 minutes

Download Splice, point it at your capture folder, and let it find your kills — no config file, no command line.

Splice watches the folder where your recorder saves clips — NVIDIA Instant Replay, AMD ReLive, OBS, Xbox Game Bar, Medal, anything that drops files into a folder. When a new recording finishes, it either uploads the whole clip to a vision model or samples a handful of frames, asks “did someone die here?”, and cuts that moment out as its own clip if the answer is yes. That’s it.

Here’s how to get running.

  1. Download and install

    Grab the installer from the download page. Run it — Windows will show a SmartScreen prompt the first time since the app isn’t code-signed yet. Click “More info” then “Run anyway”. It installs to your user folder and doesn’t touch system files.

  2. Add your API key (during onboarding)

    Splice sends clips to an AI service called OpenRouter — think of it as a router that lets you pick which model looks at your clips. You’ll need a free account at openrouter.ai and an API key. On first launch a short onboarding tour pops up and prompts you for it in the AI setup step. (You can also edit it later in Settings → General → OpenRouter API Key.)

  3. Pick your capture folder

    The onboarding’s Folders step shows folders Splice already detected (NVIDIA App / Instant Replay, AMD ReLive, OBS, Xbox Game Bar, Medal) — click Add next to one. Otherwise click Pick a folder manually and navigate to your recordings folder. NVIDIA’s default is usually C:\Users\<you>\Videos\ with per-game subfolders inside. Splice only reads from this folder — it never moves or changes your files.

  4. (Optional) Disable games you don't play

    Built-in profiles for Valorant, Apex Legends, CS2, CS:GO, Fortnite, Warzone, Arc Raiders, and Marathon are all enabled by default. To turn one off, open the Models tab in the sidebar and toggle its game card. You can also add a custom game from the same page.

  5. You're done — let it run

    Drop back into your game. The next time your recorder saves a clip, Splice will pick it up automatically, analyze it in the background, and surface any kills in the Dashboard. The system tray icon turns blue (with a play arrow) while it’s processing a clip, and gray when idle — right-click it for a live queue summary.

What happens next

Once analysis finishes, head to the Dashboard to see your clips grouped by game, with kill thumbnails under each row. From there you can edit kill detection, jump to the editor to trim, or send a highlight straight to the Explore feed.
