Flow description
Purpose and benefits
Overview
This workflow, named Letter Generator, is designed to help users quickly generate high-quality, context-appropriate letters using a large language model (LLM). It offers both ready-made letter generation buttons for common scenarios and a fully customizable input for any situation. The process ensures the generated letters are tailored, concise, and free of generic or filler content.
How the Workflow Operates
The flow consists of several key components and user interactions:
Preset Letter Buttons: Three button widgets allow users to generate:
- A formal letter to a boss about a project update
- An apology letter to a spouse
- A legal letter to the tax office
Each button, when clicked, displays the prompt text in the chat area, providing immediate feedback on what will be generated.
Custom Letter Input: Users can enter their own specific letter requirements in a chat input field. This input is then used to dynamically create a prompt for the LLM, ensuring the letter matches the user’s requested style, recipient, and purpose.
Detailed Flow Structure
| Component | Purpose |
|---|
| ChatInput | Accepts user’s custom letter request or requirements |
| PromptTemplate | Transforms user input into a clear, structured prompt for the LLM |
| Generator | Uses the prompt to generate a letter via a large language model |
| ChatOutput | Displays generated letters or prompt text to the user |
| ButtonWidget (x3) | Provides quick-access, one-click letter generation for common cases |
| ChatOpenedTrigger | Initializes the chat session and makes preset buttons available |
Workflow Steps
User Initiation
- When the chat is opened, preset letter buttons become available.
Preset Button Usage
- Clicking a preset button (e.g., “Apology letter to spouse”) shows the prompt text in the chat output, ready for further processing or review.
Custom Input Usage
- The user can enter a unique letter request in the chat input field.
- The input is combined with a carefully crafted prompt template. This template guides the LLM to:
- Use the specified style (formal/informal) and recipient name if provided
- Keep the letter under 500 words unless otherwise requested
- Avoid generic, filler language and focus on clear, direct content
Letter Generation
- The prompt is sent to the generator (LLM), which outputs a full letter based on the instructions and the user’s input.
Output Display
- The generated letter is shown in the chat output, ready to be copied, sent, or further refined as needed.
Advantages and Usefulness
Automation & Scaling
- Efficiency: Significantly reduces the time required to create personalized letters, especially for repetitive or common scenarios.
- Consistency: Ensures all letters follow a structured, professional format, avoiding overused phrases and unnecessary fluff.
- Customization: The prompt template allows for granular control, enabling the generation of almost any type of letter as needed.
User Experience
- Ready-made Templates: The preset buttons speed up common letter-writing tasks.
- Interactive Feedback: Users see prompt text and outputs in real-time, making the flow intuitive and transparent.
- Flexible Personalization: By allowing custom input, the workflow adapts to any letter-writing need, from business to personal matters.
Example Use Cases
- HR Departments: Quickly produce standard letters for performance updates, recommendations, or apologies.
- Legal and Administrative Staff: Generate formal letters for government or tax offices.
- Individuals: Write personalized messages for sensitive situations (e.g., apologies, requests, updates).
This workflow is especially useful for organizations or individuals looking to automate and scale their letter-writing process, save time, and maintain a high standard of communication across different contexts.
