Ask follow-ups for clarity Always verify AI responses against source materials Use collections and clear titles to keep conversations organized ### Effective prompting tips 1. **Start with context** - Explain what you're working on 2. **Be specific** - Ask precise questions rather than broad ones 3. **Request format** - Specify if you want lists, paragraphs, or tables 4. **Provide examples** - Show the AI what you're looking for 5. **Follow up** - Build on previous responses with clarifying questions **Example progressive conversation:** ``` You: I'm researching neural network optimization for medical imaging. You: What are the current state-of-the-art optimization algorithms used in this field? AI: [Provides response about Adam, RMSprop, etc.] You: Can you compare Adam and RMSprop specifically for small medical imaging datasets (< 1000 samples)? AI: [Provides detailed comparison] You: What would be the best approach for my dataset of 500 chest X-rays? ``` ## Troubleshooting You have three options: 1. Wait until the 1st of next month for your reset 2. Switch to a different model type 3. Upgrade your tier for higher limits AI models can make mistakes. Always: * Verify against source materials * Cross-check important facts * Ask for clarification or sources * Use multiple models for important queries Chats are saved automatically, but: * Check if you're logged into the correct account * Look in the "All Chats" view, not just "Recent" * Check if you accidentally deleted it * Contact support if the issue persists This can happen due to: * Token limits on the model * Network interruption * Click "Regenerate" to try again * Or ask the AI to continue with "Please continue" You can use AI as a research assistant, but: * Always write in your own words * Use AI for brainstorming and understanding * Cite sources properly, not the AI * Check your institution's AI usage policies * Never submit AI-generated text as your own work ## Keyboard shortcuts Speed up your chat workflow: | Action | Shortcut | | ----------------- | --------------------------------- | | New chat | `Ctrl/Cmd + N` | | Send message | `Enter` | | New line | `Shift + Enter` | | Edit last message | `Ctrl/Cmd + ↑` | | Regenerate | `Ctrl/Cmd + R` | | Copy message | `Ctrl/Cmd + C` (hover on message) | | Delete message | `Delete` (hover on message) | [See all shortcuts →](/reference/keyboard-shortcuts) ## Related features Link papers to chats for context-aware conversations Organize chats into topic-based collections Compare model access across different plans Learn advanced strategies for using AI chat effectively
