Brief Overview

This is composed using (the old version 4 of) Brain Annex – visible to you in read-only mode because you're not logged into this account.

Brain Annex is open-source.

The "classic" version 4 was specifically web app for Knowledge and Media Management.

By contrast, the new version 5 is a much more general full stack based on a graph database.

Who Is It For?  (this section applied to the "classic" old version 4)

Anyone who has NOTES or MEDIA that you'd like to have at your fingertips – effortlessly organized, searchable and updatable – from any location!

For professionals, students, scientists, companies, non-profits, artists, engineers, parents, teachers, working people, people from every walk of life... You! 

Need something simple? If you can post status updates on social media, you can use Brain Annex in its basic functionality!

You are a Power User? Brain Annex was created by people like you who desperately needed an very powerful tool!

Business User? Brain Annex is a platform that allows you to easily create plugins for your specific neeeds.

What Can It Do?

Knowledge and Media Management made easy, powerful and convenient. A "dump" of your notes or media doesn't do much good... but when storage is combined with threading and easy searching – that's when it can feel like a handy "annex" of your brain!

Brain Annex supports multiple accounts, and multiple users within each account - with assignable permissions.

Users can freely mix up notes or media, including complex objects supported by modular plugins; for example:

• formatted text notes
• documents
• images
• graphics
• data tables
• video
• music
• plots
• (coming soon) spreadsheets

Every content item (such as a formatted text or image) can be attached to various Categories and other Tags, allowing for browsing.  A powerful search function is an integral part.

For casual users, it's akin to posting on social media, or keeping albums there.

Power users can create complex web of categories, user-defined fields and many other advanced features.

Businesses and developers can greatly adapt it to their needs with easy-to-create plugins.

Examples of uses for Brain Annex

• class notes
• work/research notes
• notes from hobbies
• notes from everyday life (bills, medical, car maintenance)
• personal-growth notes (journaling, progress)
• music collection
• photo/video collection
• website bookmarks
• documents
• optionally sharing some of of your pages with others or making them public

How Can I Use It?

• You just need a browser and an account

How Do I Get Started?

• Install it on any typical shared webhost service
  OR
• Install it on your local computer

What Does it NOT Do? 

• Even though pages may be created and made public, essentially creating an open website (as done in this documentation), Brain Annex is not designed to be a general website editor
   
• While Brain Annex can indeed be used on a smartphone (though a browser), it currently isn't optimized for tiny screens.  For anything more complex than a shopping list, we recommend using a pad or larger device.

You can freely mix up notes or media, including complex objects supported by modular plugins; for example:

• formatted text notes
• documents
• images
• graphics
• data tables
• video
• music
• plots

Examples of some are given below.... 

Note: if you were logged in, you'd see controls to edit/delete/reposition/tag the various items 

This is an example of a simple text note.  That's similar to a stick-it note.

This is an example of a complex formatted note

Brain Annex provides a text-formatting editor named CKEdit, akin to what you find in WordPress and other software.

You can do the usual boldface, italics. undelines, strikeout, etc.   

x² and x_i . 

Colors, backgrounds, sizes, fonts, etc.

Indented paragraphs.

Basically, the typical word-processor operation.

 Emojis, of course 

Yes, you can include photos within the text...

You can have formulas...

\(F(\xi) \triangleq \left\{ \{x = \log_{10}{\int_{-\infty}^{\pi} {-b \pm \sqrt{b^2-4ac \sin(\xi)} \over 2a}}\otimes\partial f/\partial t\}\Rightarrow\{\lim_{\delta \rightarrow \infty}[\arcsin(\delta)] = \oint_a^b\det\begin{bmatrix}\frac{\text{d}x}{\text{d}y} & \sum_a^b f''(x) \\\frac{\partial a}{\partial b} & \sqrt[n/t]{ab} \end{bmatrix}\} \right\}\)

\(f = \underbrace {x^3} _ \textrm {text 1} + \underbrace {2 + sin(x)} _ \textrm {text 2} \oplus \mathbf{V_0}\)

and let's not forget widgets!  

IMPORTANT :

this documentation is for the "Classic" (PHP-based) version 4 of Brain Annex.  As of version 5, released in Beta in Dec. 2021, the internals of Brain Annex have been completely overhauled to a Python/Neo4j implementation.  Details

=> FOR THE DOCUMENTATION OF THE NEW VERSION (v. 5) of Brain Annex, go here.

However, the UI is still generally-recognizable from what was shown in the Screen shots section and in the following 2 short intro videos:
