## Optimization Modes

Promptheus offers three optimization modes to control how your prompts are processed:

#### 🤖 Auto Mode (Recommended)

Intelligently detects your task type and decides whether to ask clarifying questions. For analysis tasks (research, explanation), it skips questions and directly optimizes. For generation tasks (writing, creation), it asks relevant questions to improve quality.

#### ❓ Always Ask Mode

Forces Promptheus to generate and ask clarifying questions regardless of task type. Useful when you want maximum refinement and are willing to answer detailed questions.

#### ⚡ Skip Questions Mode

Bypasses the question-asking phase and directly optimizes your prompt. Best for quick optimizations or when you've already provided detailed requirements.

## Question Flow

Interactive questionnaire guiding prompt refinement with progress tracking and required fields

When Promptheus determines that questions would improve your prompt, it presents an interactive questionnaire:

### Question Types

- Multiple Choice: Select from predefined options (e.g., target age range, tone, format)
- Text Input: Provide free-form answers for open-ended questions
- Checkbox Lists: Select multiple applicable options

### Answering Questions

1. Review the question displayed at the top of the panel (e.g., "Question 1 of 5")
2. Select your answer by clicking the appropriate option or typing your response
3. Navigate questions - some questions may influence which follow-up questions appear
4. Submit answers - once complete, Promptheus processes your responses

💡 Question Quality

Promptheus uses AI to generate contextual questions specific to your prompt. Questions for a "write a story" prompt will be completely different from a "explain a concept" prompt.

The interface shows:

- Progress indicator (Question X of Y)
- Current question text with required field markers (*)
- Cancel button to abort the process
- Processing status while the AI generates your optimized prompt

## Working with Results

After processing, Promptheus displays your optimized prompt in the output panel. The result includes:

### Output Features

- Enhanced Prompt: Your original prompt transformed into a detailed, effective instruction
- Structured Requirements: Clear sections outlining requirements, constraints, and expectations
- Context Integration: Answers from clarifying questions seamlessly incorporated

### Available Actions

#### 📋 Copy Button

## Frequently Asked Questions

How do I switch between providers?

Use the Provider dropdown in the top navigation bar. You can switch at any time, even between optimizations. Make sure you have configured an API key for the provider you want to use.

What happens if I don't answer all the questions?

Required questions (marked with *) must be answered. Optional questions can be skipped. The optimization quality improves with more complete answers, but Promptheus will work with whatever information you provide.

Can I use the optimized prompt with a different AI model?

Absolutely! Optimized prompts work with any language model. Copy the result and use it with ChatGPT, Claude, Gemini, or any other AI assistant. The optimization focuses on clarity and structure, which benefits all models.

How is my data stored?

All data (API keys, prompt history) is stored locally on your machine. Promptheus only communicates with AI provider APIs to process your prompts. No data is sent to Promptheus servers (there are none!).

Which mode should I use?

Auto Mode is recommended for most users. It intelligently decides when questions are helpful. Use Always Ask when you want maximum refinement, and Skip Questions when you need quick optimizations or your prompt is already detailed.

Can I edit the optimized prompt?

Yes! After copying the optimized prompt, you can edit it in any text editor or AI interface. You can also use the "Tweak" button to refine it further within Promptheus.

What's the difference between providers?

Each provider has unique strengths: Google Gemini offers excellent free tier; Claude excels at reasoning and following instructions; OpenAI GPT is well-balanced; Groq provides fastest responses; Qwen/GLM are optimized for Chinese language.

How do I clear my history?

History can be cleared using the CLI command `promptheus history --clear` or by accessing the history management features in the web interface (if implemented).

## Troubleshooting

### Common Issues

Web UI won't start

Solution:

- Check if port 8000 is already in use: `lsof -i :8000` (Unix) or `netstat -ano | findstr :8000` (Windows)
- Try specifying a different port: `promptheus web --port 8080`
- Ensure Promptheus is properly installed: `pip install --upgrade promptheus`

API key not working

Solution:

- Verify the key is copied correctly without extra spaces
- Check if the key is active in your provider's console
- Ensure you have sufficient credits/quota with the provider
- Try testing with a different provider to isolate the issue

Optimization fails or times out

Solution:

- Check your internet connection
- Verify provider API status (check provider's status page)
- Try a different provider or model
- Reduce prompt complexity if it's very long
- Check rate limits on your API key

Questions not appearing

Possible reasons:

- Mode is set to "Skip Questions" - change to "Auto" or "Always Ask"
- Your prompt type was detected as analysis (Auto mode) - try "Always Ask" mode
- The AI determined no questions were needed - this is normal for some prompts

Browser doesn't open automatically

Solution:

- Manually navigate to the URL shown in terminal (usually http://127.0.0.1:8000)
- Use `promptheus web --no-browser` flag to suppress automatic opening
- Check if your default browser is set correctly
