Scott's profile picture

The brains that you can create from information you have already created and then interact with, is one of the most brilliant features of any AI I have come across.

Edward - United States

I work across several fields (business, tech, non-profit development, start-ups, education, health, fiction writing, and a few more) and wanted a system that allowed me to quickly cross-connect without hiding things in folders and sub-folders festooned with tags.

Gil C - Executive Director

I like how easy it is to create specialized brains based on personal or professional files, documents, notes, and web pages in the application. I have personally created hundreds of reports over my career, and I can upload those and those of my colleagues to create a specialized brain.

Escape the Chaos. Find Your Focus.

Data Scattered Everywhere

Your ideas live across PDFs, Notes, Notion pages, and web clips; but never in one place.

Hours Lost Searching

You waste time hunting for what you've already read, written, or saved.

Manual Task Switching

Every app holds a fragment of your mind; switching between them kills your flow.

Information Overload is Real

You struggle to make sense of large amounts of data, documents, and digital content.

What Users Say About Super Brain

Real feedback from Elephas users on

Capterra

Great in-line AI and RAG Tool!

In-line use of AI and use of “Super Brains” to allow query of your own content.

ScottUnited States

If they take away Elephas from me I will lose my job

I am biased when it comes to talking about Elephas; I use it for absolutely everything. From rewriting a text for me to reminding me of facts I didn't even remember (with Brain).

GabrielBrazil

Elephas versatile, context aware AI tool

I have been using this software on a daily basis and it has become an essential tool for automating various tasks. From replying to messages, writing articles, to creating technical documentation, this software has significantly streamlined my workflow. One of the aspects that I truly appreciate about this software is the responsiveness of the developers. Whenever I encounter a bug or have a feature request, they are quick to address the issue and provide updates. Their commitment to improving the software based on user feedback is commendable and ensures a smooth user experience.

MicheleGermany

Flexible AI tool with superb functionality

The Super Brain function is brilliant. It's my daily driver. Also, I can use chat with a local LLM, so everything stays local. And it can export the results directly into a Keynote presentation - if you have a ready presentation template, you can be set in 5 minutes.

KamilPoland

Elephas Super Brain

The capability to handle more contact, deal with more emails and refine my content has been a real help for me as I set up my new company. It is intuitive and learns as it goes.

SeanIreland

Elephas AI: The Good, The Great, The Semi-Bad, and the Polished “Uglies”

The brains that you can create from information you have already created and then interact with, is one of the most brilliant features of any AI I have come across. you can get new perspectives on information that you have already curated, only helping expand what you can do..

EdwardUnited States

Elephas is the best at bringing AI to my fingertips

The killer feature is the close integration with my OS. I have AI superpowers every time I need them.

LucaItaly

King of AI clients

I've tried pretty much every local AI client on my Mac, but Elephas may be the best. Really centres on building knowledge bases (aka 'Brains') which is a common use case I have. Also provides all the other tools you'd expect (chat, text replacement, personas/tones etc).

BenUnited Kingdom

Game changer for your productivity

I like the fact that you can create brains, bringing your own data, and chat with it, as it was some sort of Yoda character. This is a game changer. By far the best app of its kind as of the moment.Additionally, the team is very proactive bringing up new updates and fixing small bugs. Kuddos and continue the great job.
