With the growing popularity of AI art tools such as Nano Banana and Stable Diffusion, creators often face a pain point: the high threshold for writing complex prompts, heavy memory burden, and even minor formatting errors can affect image quality.

Recently, an open-source structured prompt generation tool called PromptFill has emerged. Through its innovative "fill-in-the-blank" visual interaction, it significantly reduces the difficulty of creating prompts, making AI art truly "foolproof" to use. Core features: Fill-in-the-blank interaction, drag-and-drop to generate prompts. The traditional long-text prompt is broken down into individual "variables," and users just need to click, drag, and fill in the blanks to quickly build a complete prompt structure.

The tool includes an intelligent keyword library with categories (such as characters, actions, styles, scenes, etc.), supports adding custom keywords, and offers real-time preview and bidirectional synchronization. One-click copy of clean text or export of high-resolution images, directly paste into AI art software for use, without worrying about spelling or format issues. It solves the pain points of AI art creation, greatly improving the efficiency of creation. No need to remember a large number of keywords: commonly used elements can be called with one click, avoiding repeated searches.

No format errors: the system automatically handles details like commas and weights.

Easy iteration management: supports saving multiple templates and version control, allowing modifications and reuse at any time.

Local privacy first: all data is stored locally in the browser, not lost on refresh, suitable for users who are sensitive to privacy.

Open-source community praised, received positive reviews upon release. Since the GitHub project was open-sourced, PromptFill has been updated to version v0.5, with a significant UI optimization and support for desktop and mobile dual-end adaptation. Community feedback says: "Finally, no longer need to pile up prompts in a notebook. The fill-in-the-blank workflow has brought back the sense of order in creation." Developers continue to update more preset templates, and welcome user suggestions for improvements. Applicable users and usage tips: PromptFill is especially suitable for AI art beginners, content creators, and professional designers. New users can quickly get started by using built-in templates; advanced users can customize the keyword library to create their own prompt system.
