Start Your First Conversation

After entering the chat interface, you’ll see a chat-like interaction area. The Expert may send an opening message introducing what it can do.Try sending a message — for example:
  • “Help me write a short article about AI”
  • “Analyze the issues in this code”
  • “Help me create a project plan”
The Expert will reply in real-time streaming, just like chatting with a real human expert.

Try Uploading a File

Next to the chat input box, you’ll see a file upload button. Experts can process various file types:
  • Documents: Word, PDF, PPT, Excel
  • Code: Source code files in various programming languages
  • Images: Screenshots, design mockups, photos
  • Archives: ZIP-format project files
Try uploading a file and ask the Expert to analyze or process it.
File size and storage space are subject to your plan limits. Refer to the real-time display within the product for details.

Explore the Workspace Panel

If the Expert you’re using has the sandbox workspace enabled, a workspace panel will appear on the right side of the chat interface:
  • Code Editor: View and edit code generated by the Expert
  • Website Preview: Preview web pages built by the Expert in real time
  • File Browser: Manage all files in the workspace
  • Terminal: View command execution results
Files in the workspace are persistently saved — close the browser and come back, and your files will still be there.

Useful Tips for Conversations

Plan Mode

Activate Plan Mode from the ”+” menu in the input box. The Expert will first research and create a plan, then execute after your confirmation

Multi-turn Conversations

Experts understand context. You can keep asking follow-up questions and modifying requirements within the same session — the Expert remembers previous content

Select Plugins

Some Experts offer optional plugins (e.g., website building, video production). Enable them as needed from the ”+” menu before chatting

Temporary Chat

If you don’t want the Expert to remember this conversation, you can select “Temporary Chat” mode before starting

​
Managing Your Credits

Each AI conversation consumes credits, and the amount depends on the model used and the type of interaction. You can check your current credits balance from the avatar menu in the top-right corner. When you’re running low on credits, you can:
  • Upgrade your plan: Higher-tier plans include more credits and features
  • Purchase a top-up pack: One-time credits recharge
Bonus credits have an expiration date and will automatically expire if unused. Purchased credits do not expire. Refer to the real-time display within the product for specific expiration details.
