WorldBrain’s vision is a well-informed, less polarised society, that enjoys full data ownership and privacy.
We want to foster a mindset empowering people to make life's most important decisions with clarity and purpose.
So we built Memex, a bookmarking tool for great thinkers.
For those who are curious enough to keep an open mind and bold enough to admit they're wrong.
With Memex, we want to make it 10X+ faster for individuals to organise, recover and share the most useful and trustworthy content they find on the web.
Your data is fully stored locally on your device. We will never have access to it without your approval.
Depending on your plan, it is either kept only locally, or fully encrypted for back-up in the cloud.
Additionally, we receive anonymized usage statistics about how people use the extension.
You can always opt-out and we respect the browser’s ‘do not track’ requests.
Our software is open-source so you can verify these claims yourself by looking at our source code.
Until now we’ve been funded by personal investments of the founder Oliver Sauter and a grant by Digital Science.
Soon, our cloud service will help us meet the bottom line.
We currently crowdfund its development.

Per url visited it stores on average around 140kb. If you are a heavy web user with 30.000 visited documents you end up with about 4GB of data per year.
Our cloud plan allows you to send this to the cloud.
While being idle, the extension needs around 80MB of Ram, which can go up to about 250-300 when you are opening the search overview or settings. Only when importing your previous history or bookmarks, the extension gets demanding.
The only CPU spikes you’ll experience are small peaks when you import your history and bookmarks, or about 10 seconds after you visit a website, because of the resources needed to index pages.
Users with a modern setup should not experience any lag. Some low-spec machines may do, but we are constantly working on performance improvements.
With our upcoming premium service, you can also offload most of that work to the cloud.
