Jewel Box

a place for what's most cherishable

(currently public-beta)

A home for privacy respecting apps 🛡

Jewel Box provides a suite of rich, persionalized, web apps in one account. Your data is kept in JewelBox.app and encrypted by default. With "My Keys" mode only you have encryption keys.

We make money from fees based on usage of digital resources. Fees become ~$0 if you don't use the service (excl. storage costs). This is not a monthly subscription model.

Sera AI Assistant

Sera: Your private AI assistant

Sera, our first web app, is an AI assistant built on state-of-art OpenAI tech. Highlights:

  • Sera doesn't give ownership of chat data to OpenAI[1]
  • Encrypts chats by default and stores them securely in JewelBox.app.
  • Pay‑as‑you‑go access to flagship AI models - will likely be cheaper unless you are a very heavy user.
  • “My Keys” mode keeps sensitive chats fully private.

[1] Per OpenAI, 2023-3-1: API data isn't use to train / improved models. We also disable storing objects in OpenAI.

More apps on the way ...

We are working on Calendar, Notes and Photos. We think integrating these apps into Sera will make them compelling and fun.

... and we have more planned for the future.

A word about cost

Even though we prioritize user experience first, we can still deliver these services at incredibly low prices.
This directly stems from staggering advances in computing technologies, which we pass on to users.

No lock-in

We provide various ways of downloading your data in case you choose to move to a different service.
We ❤️ you regardless.
