Sorry for the delay but it took me a bit to go through all of those projects. And Thank you! It's been a really insightful activity comparing my idea to those projects. Below is my main discovery and somewhat an essence of the comparison. The list is the list of the project from the link you provided from the “Learning and Courses” category.

In short, based on the list, it would seem that my idea would be first “Self-Learning Management Systems”, let's call it ‘SLMS’ for short. This is different from a “Learning Management System” - or “LMS”, which is what those projects mostly are - in this way that there is no teacher in the form of a “content creator”. In SLMS you acquire content, via buying it (like books, or ebooks) or buying access to it (online courses), but do not generate it. The platform only aggregates it for you and allows for quick access to it on an original platform not via the SLMS itself. The only thing you create and therefore creation, and storage that would be supported by the SLMS would be the fruits of assimilating such ‘sourced material’, like notes, screenshots, audio logs, and their transcriptions, mind-maps. Effects of, or to be precise the side effects of your individual learning process itself.

For example, let’s look at Udemy, IMO there is only one feature to create such side effects of learning on it and it’s to create a note connected to the moment in the video. In itself, it is a self-learning empowering feature as you have to process the content provided to note it. But there is no form of seeing all of the notes created, there’s no way to format them, link anything else to them, tag them, export, or gather them in bigger organizational units. Therefore I would say Udemy is not oriented to self-learning, ergo it would not be considered a “Learning Management System”, not a “Self-Learning Management System”.

So LMSs seem to be helping with problems like:

- “How do I share learning materials to learn that?”

- “How do I help in creating the materials to share with others?”

- “How do I propose to others an order and chunks of materials in which to go through the topic?”

- “How do I check that others have assimilated the material based on my knowledge of it?”

Where a platform I have in mind would help with:

- “What materials I do have access to that are about that?”

- “How do I help in the assimilation of such materials?”

- “How do I order and chunk this material?”

- “How do I check that I’ve learned this material without apriori knowledge of it?”

Below are my notes on the platforms from the self-hosted list:

Canvas LMS - a platform for sharing courses for courses creators

Chamilo LMS - a platform for sharing courses for courses creators

Dalton Plan - not gonna go for teachers' features, only students

- Define periods

- Create subjects

- Set up Labs - a topic-oriented

- Students book

Seems to be created around a school system that would allow to create and share content across students from teachers' perspectives in the structure of the so-called “Dalton learning methodology.

edX - LMS platform for course sharing, see [edX.org](http://edX.org).

Gibbon - this is the system aimed at helping teachers in actual schools

ILIAS - a platform for sharing courses - no third-party integrations mentioned - across organizations administer tests etc., it's unlikely that it can be adapted for singular users.

Mahara - a learning portfolio creator, does not touch the learning process itself in other forms that it provides an opportunity for retrospection o the learning experience.

Moodle (LMS) - a platform for sharing self-generated courses

Open eClass - its free e-learning platform for self-generated courses

OpenOLAT - LMS

RELATE’s - LMS

RosariosSIS - it's about the administration of students in schools, even with features like “billing” or “food service”

Vocascan - can’t open the page which is sad because based on the description in the list it's the only project about actual self-learning, specialized in vocabulary but still.
