What You'll Need

  • A Aider account (free to create)
  • A modern web browser or the Aider app

Getting Started

1

Create Your Account

Visit https://aider.chat and sign up for a free account. You'll need an email address to register.

2

Start Your First Conversation

Once logged in, you'll see the main chat interface. Type a question or task in the input box and press Enter. Aider supports code, voice — start with a simple text prompt to get familiar.

3

Code Assistance

For coding help, paste your code or describe your problem: 'Here's my function, why isn't it working?' You can ask for explanations, debugging, or new code generation.

4

Voice Input

Aider supports voice input. Click the microphone icon to speak your prompt instead of typing. Useful for hands-free operation or accessibility.

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 Aider what format you want by including an example in your prompt.
  • Share context: When asking for code help, include your programming language, framework, and what you're trying to accomplish.
  • 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."
