Desktop LLM Helper

A Windows desktop application that enables seamless text processing with Large Language Models from any application. Select text anywhere, trigger a hotkey, and instantly send it to your LLM for processing. Results can be inserted directly back into your workflow or displayed in an interactive chat dialog.

Features

• System-wide hotkey integration: Access LLM capabilities from any application
• Customizable task presets: Configure multiple tasks with different prompts and behaviors
• Flexible response handling:
  • Insert Mode: Automatically paste LLM responses directly into the active application
  • Dialog Mode: View responses in a dedicated chat window with conversation history
• Clipboard integration: Seamlessly captures selected text and returns results via system clipboard
• Multiple LLM provider support: Works with OpenAI-compatible API endpoints

How It Works

1. Configure Tasks: Set up custom tasks with specific prompts (e.g., "Translate to English", "Fix Grammar", "Explain Concept")
2. Set Global Hotkey: Define a system-wide keyboard shortcut to trigger the task menu
3. Use Anywhere: Select text in any application and press your configured hotkey
4. Choose Task: A popup menu displays your configured tasks
5. Automatic Processing:
   • The application captures the selected text (simulates Ctrl+C)
   • Sends it to your LLM with the task's prompt
   • Returns the response based on your configuration:
     • Insert Answer: Automatically pastes the result (simulates Ctrl+V)
     • Show in Window: Opens an interactive chat dialog for further conversation

Use Cases

• Translation between languages
• Grammar and spelling correction
• Text rephrasing and style adjustment
• Technical term explanations
• Code documentation and refactoring
• Summarization and content analysis
• And many more...

How to Use

1. Find the tray icon and open Settings.

   

2. Configure the LLM connection (API base URL, API key, hotkey), then save the settings.

   

3. Open Tasks and create the tasks you want to run (prompt, model, response mode).

   

4. Select text in any app and press the configured hotkey (Ctrl+Shift+Space by default) to open the task menu.

   

5. Run a task. The response is either inserted into the current text field or shown in a dialog, depending on the task settings.
