Open Qwen ↗Weidu Lab · Optional AI companion
Choose where your AI runs.
Use a small model on this device, or choose a free online chat service. Bring a question from GITS, DUAL or XRT.
There is no payment or AI service key on this page. On-device AI uses your storage and battery. Online services set their own limits and terms.
1 · Prepare what you want to ask
Start with your Lab work.
Paste only the material you want the AI to use. Nothing here is read from another studio or sent to an online service automatically.
Optional. Up to 4,000 characters. Use fictional, non-sensitive material.
Ask a specific question. Review the reply yourself.
Review the prepared prompt
Each on-device request starts fresh. For DUAL, open a separate online conversation for each role and keep their first drafts apart.
2a · Run AI here
Keep generation on this device.
Download a small model, then ask your prepared question here. After the model loads, generation happens in this browser. Your prompt is not sent to a model provider.
Checking this browser’s support.
AI reply
Small models can miss instructions or invent details. Use the reply as a draft to question. The device needs a compatible browser and enough available memory; speed varies.

Your choice and your work
- Drafts and replies are held in this page’s memory. Copy or download anything you want to keep. Your browser may restore page contents when reopening a session.
- The model download is different: the browser may retain it for another visit. Use the remove button to delete this model’s cached files.
- On-device setup contacts the model and software hosts to download files. Those hosts and the site can receive ordinary connection records. Prompt generation stays local.
- Online chat uses the provider’s own privacy settings and terms. Check these before sharing anything personal.
- AI help does not establish scientific findings. The original studios and their research boundaries remain available in the Lab.
