This an open source replacement to Notion which you can import from and that syncs in the cloud and locally. Can be self hosted too.

It offers encryption locally and at any location where data is synced (local p2p network for now).

Un nouvel outil qui réunit toutes vos applications professionnelles du quotidien en une seule. C’est un espace de travail tout-en-un, pour vous et votre équipe.

Contains trackers and hosts all the data at their end though level of encryption is not known. Can be compared to OneNote but MUCH MORE powerful.

Using is for now until an open source competitor stands out (ANYTIME.IO can import data from Notion)
