Design goals from our JUWEL design rules (2026-09-24)
Ask. Remember. Forget.
01 / Ask
Start typing.
You get a first reply before you sign up. Starter ideas are there if you want them. There is no tour.
02 / Remember
Only after you say yes.
A list called “What JUWEL knows” shows everything it keeps, and the day it learned it.
03 / Forget
One item, or everything.
Remove things from the list, or just say “forget that”. If you delete a chat, its memories still show in the list.

Common questions
About JUWEL.
Is JUWEL an agent?
No. It is an assistant you talk to. It can be lent narrow, approved agency: connected actions wait for your yes.
Does JUWEL need an account?
No. You can start as a guest and get a first reply before you sign up.
Which actions ask first?
Connected actions wait for your approval. Today the server-gated set is a calendar event and a mail draft.
What is not live yet?
Gems open weights, Stones, VKP as open source and the Fusion Gateway are coming, not live.
Built on work you can check.
We show how we test each idea, what we found, and where it stops working.
What this page does not claim.
Research stays research. Our papers test ideas on tiny models and regular computers. They are not a list of JUWEL features.
Screenshots and designs are labelled. The front door is a dated screenshot of the live app. The memory screen is a design, not the real app. See the real app on juwel.ai.
