How to install Subtitle Generator
The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:
- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
subtitle-generatorand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Subtitle Generator with a single command:
openclaw skills add subtitle-generator
This pulls subtitle-generator from ClawHub and installs it into ~/.openclaw/skills/subtitle-generator/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Subtitle Generator
Once installed, Subtitle Generator activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Turning video into a finished short
Subtitle Generator works with video. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — reframes to vertical, cleans the audio, cuts dead air, burns animated captions, and exports a version sized for TikTok, Reels, and Shorts.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
Manual install (advanced)
If you prefer manual installation:

subtitle-generator-1.0.7.zipdirectly from our S3 mirror. - Unzip into
~/.openclaw/skills/subtitle-generator/(create the directory if it does not exist). - Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
