Hey Product Hunt! I’m Zhao Cong, the maker of Promptform — a Mac app for turning prompts you reuse into templates with fill-in variables.

The idea came from making AI videos that shared the same storyboard. For each video, I want to change the scene and transition effects while keeping everything else consistent. Repeatedly editing the same prompt made me want a simpler workflow: save the instructions that work, then fill in only what changes.

That’s why I built Promptform around Quick Launcher. While the app is running, press Command-Shift-Space from any app to:

• Find a saved prompt template.
• Fill in variables like scene, topic, or tone.
• Copy the finished prompt and paste it into your preferred AI tool.

All without opening the main library window.

You can use it for recurring tasks like social posts, marketing emails, video scripts, and content briefs. Your prompt library is stored locally on your Mac, with tags, search, and export to help keep it organized.

What’s next:

I’m planning more Quick Launcher features, more ways to organize and manage your prompts, and more variable types for different workflows.

What tasks do you reuse prompts for most often, and which details do you change each time? I’d love to hear about your workflow.
