Pro Tips

  • Be specific: The more context you provide, the better the response. Instead of "write an email," try "write a professional follow-up email to a client who hasn't responded in two weeks."
  • Iterate: If you don't get what you need, ask for clarification or refinement: "Make it shorter" or "Use a more formal tone."
  • Use examples: Show Open WebUI what format you want by including an example in your prompt.
  • Save useful conversations: Most platforms let you name and revisit conversations — organize by project or topic.

Troubleshooting

Responses seem generic or unhelpful
Add more context to your prompt. Specify the audience, tone, length, and format you need. Try starting over with a clearer description of your goal.
The tool isn't responding or is slow
AI chatbots can experience high traffic. Refresh the page and try again. Check the service's status page if issues persist.
Output is too long or too short
Explicitly specify the length: "in 100 words," "as a brief summary," or "in detail with examples."
