Prompt Builder

Prompt Builder for macOS

Prompt Builder is a specialized macOS tool designed to streamline the creation of complex, long-context prompts for large language models such as OpenAI's o1 and Gemini 2.0. This application is invaluable for users who need to aggregate a myriad of content types—text files, transcripts, images, and more—into a cohesive prompt without the manual hassle.

Key Features

• Local File Integration: Effortlessly add local files and view estimated token usage.
• Web and Video Content: Automatically fetch content from URLs or YouTube for inclusion in prompts, with optional summarization.
• Text Summarization: Keep prompts concise by summarizing lengthy texts before injection.
• Audio/Video Transcription: Quickly transcribe media files such as .mp3, .mp4, and .wav using OpenAI Whisper or Gemini technology.
• Image Captioning: Generate descriptive captions for images to enhance prompt richness.
• Metaprompting: Create reusable prompts with dynamic placeholders for efficient prompt iteration.
• Web Search Capabilities: Perform comprehensive web searches via platforms like Exa and Brave, adding results to your prompts.
• Snippet Management: Save and insert frequently used text blocks or instructions with ease.
• Community Snippet Libraries: Leverage community snippet contributions to enhance prompt development (feature planned).
• Data Privacy and Ownership: Fully local data management, requiring user-provided API keys for external services like OpenAI, Anthropic, or Google.
• Automatic Text Formatting: Ensures prompt text is correctly formatted using XML or code blocks.

Ideal Use Cases

Prompt Builder is perfect for scenarios requiring the integration of extensive reference materials, such as:

• Software Development: Integrating extensive codebase references into Language Learning Models (LLMs) for advanced tasks like code refactoring.
• Creative Writing: Collating a large variety of documents, notes, and research efficiently, with options to summarize to stay within token limits.
• Journaling and Idea Generation: Reflecting on personal logs, diaries, or voice memos by embedding them within prompts for insightful brainstorming.
• General Long-Context Scenarios: Aggregating hundreds of disparate content sources into a seamless prompt with minimal input effort.

The primary advantage of Prompt Builder lies in its capacity to offer ergonomic solutions for building extensive, sophisticated prompts in a single unified interface—complete with real-time token count updates.

Usage Example

1. Access a folder in the left panel to view local files such as PDFs and documents.
2. Select a file to add its content to your prompt, observing token counts.
3. Input a YouTube URL; Prompt Builder retrieves and processes the transcript.
4. Incorporate custom text blocks with placeholders for dynamic value injections.
5. Use the “Assemble & Copy” function to compile the final prompt in one step.

This intuitive workflow simplifies the assembly of complex prompts, saving time and effort while maximizing prompt quality.
