What did we decide about the Asia expansion timeline?

Elephas

Based on the Q3 board meeting notes, the Asia expansion was pushed to H2 2025 due to regulatory concerns in Singapore. The team agreed to prioritize Japan market entry first.

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.

Kevin- Professional Engineer, US

Your Knowledge Is Scattered. Your Time Is Wasted.

Important ideas buried across PDFs, notes, and apps. You re-search things you already know. And generic AI tools don't understand your work.

Scattered Across Tools

Your insights live in PDFs, Apple Notes, Notion, emails, and Slack. Never in one searchable place.

8+ tools daily

Context Fades

"I know I read this somewhere..." You remember the idea but not where, or exactly what was decided.

70% forgotten in a week

Hours Lost Searching

You waste hours re-searching things you've already read, written, or saved. Because no tool connects it all.

2+ hrs/week searching

Frequently Asked Questions

Got questions? We've got answers.

Elephas is not a general-purpose chatbot. It works specifically with your documents, notes, and files to give you answers grounded in your own knowledge, with citations to your original sources. You also control where AI runs: offline with a local model, through cloud APIs (no training on your data), or with your own API key. No other tool gives you this combination of personal knowledge search and privacy control.
You're in control. Your data stays on your Mac by default and is never used to train AI models. You can run Elephas 100% offline with a local model, use cloud AI via OpenAI and Claude APIs (where your data is not used for training), or bring your own API key. See our data storage article or follow this offline guide.
No. Elephas includes its own AI, powered by OpenAI and Anthropic models. You can also bring your own API key from 15+ providers including OpenAI, Claude, Gemini, Groq, DeepSeek, and more. No separate account needed to get started.
Yes. Almost all features support all popular languages.
You can run 100% offline, by following this guide.
Super Command lets you use Elephas in any app on your Mac with one keyboard shortcut. Select text in Mail, Safari, Slack, or any app, then summarize, rewrite, translate, fix grammar, or run custom commands you create (called Snippets). It works everywhere without switching apps.
