What is PromptFill?

PromptFill is a structured prompt generation tool designed specifically for AI drawing. Through a visual fill-in-the-blank interaction, it helps users quickly build complex prompts. It solves the problems of traditional prompts, such as memory overload, grammatical confusion, and poor reusability, and supports mainstream AI drawing platforms such as Stable Diffusion and Midjourney. Core features include intelligent word library management, color-coded categorization, a multi-template system, visual drag-and-drop editing, automatic persistent storage, and export/sharing. The latest version 0.5 adds dynamic preview, long image export, and mobile adaptation. Users can freely combine template variables to generate high-quality prompts, significantly lowering the learning curve for AI drawing.

PromptFill's main functions

  • Structured Prompt Engine:support {{variable}} The syntax automatically converts text templates into interactive forms.
  • Dynamic lexicon systemIt comes pre-loaded with hundreds of commonly used art tags, and supports categorized management, custom expansion, and batch import.
  • High-definition social sharingBuilt-in template cover rendering, supports one-click export of beautiful JPG long images (automatically extracts ambient colors).
  • Template/Version AwarenessOfficial templates are synchronized with the cloud, so you can get the latest templates and features without manually refreshing.
  • Pure local storageBased on browser LocalStorage, no registration or login is required, and you have complete control over your data.

The technical principle of PromptFill

  • Front-end technology stackPromptFill is built on modern front-end technologies, using Vite as the build tool, React as the framework, and Tailwind CSS for styling. This combination of technologies ensures high application performance and a good user experience.
  • Data storagePromptFill uses the browser's LocalStorage for data storage. This method eliminates the need for user registration and login, ensuring all data is stored locally and protecting user privacy and security.
  • Template and Thesaurus ManagementPromptFill supports [various functions] through a structured template engine and a dynamic thesaurus system.{{variable}}The syntax transforms text templates into interactive forms. Users can customize dictionary categories, import tags in batches, and distinguish different categories by color, improving management efficiency.
  • Visual InteractionPromptFill supports a WYSIWYG editing mode, with variables highlighted by category color, and allows for direct text editing and structure adjustments. It also supports drag-and-drop variable insertion and drop-down menu selection in preview mode, enhancing the intuitiveness and convenience of the interaction.
  • Image processingPromptFill uses html2canvas technology to implement image export functionality. Users can export the currently filled-out Prompt template as a high-resolution image for easy sharing and archiving. The system also supports preview display, custom uploads, and image manipulation, enriching the visual experience.
  • Version awareness and updatesPromptFill features template and version awareness, enabling it to detect official template updates in the cloud in real time. Users can access the latest templates and features without manually refreshing, ensuring they always have access to the most up-to-date resources.
  • Multi-template systemPromptFill supports creating multiple independent Prompt templates, with variable selections for each template remaining independent. Furthermore, it supports copy cloning, facilitating A/B testing or fine-tuning.
  • Automatic persistencePromptFill uses LocalStorage to automatically save all changes, including templates, thesaurus, and category configurations. Data is not lost even if the user refreshes the page or closes the browser, ensuring data persistence and stability.
