Hey eloff,

Oli here, from the team developing Memex. Memex is open-source, so the browser extension will always stay free to use.

What we will charge for are some of the services that require us to host stuff. Like backups, multi-device syncing, API calls etc. We will run it as a completely modular pricing model, where you can upgrade on only those features you need. We don't like those usual 3 tier model, where you have to upgrade to the 'monster mega plan' in order to just get one feature :) But you can also completely self-host that, as we will make the server software open-source as well.

Hope Memex can be useful to you. We are running a crowdfund to support its development, where we offer some good discount on the future features in return: worldbrain.io/pricing

Let me know if I can be of more help.
