Elephas

A private knowledge workspace for sensitive files

Visit official site

What Elephas is

A knowledge workspace that keeps your material on your own devices. It indexes documents and notes locally, then lets you ask questions and write with that material as context.

The point is working with sensitive files without uploading them somewhere else.

What you can do with it

  • Index documents and notes on your device
  • Ask questions across your own material
  • Draft text using your files as context
  • Organise notes and references
  • Work with confidential documents
  • Use it on Mac and iOS

Who it is for

  • Consultants handling client material
  • Researchers with sensitive sources
  • Knowledge workers who want local control
  • Anyone uncomfortable uploading files to a service

What to watch out for

  • Confirm which parts actually run locally and which call a model provider
  • Local indexing still needs backups, or the index dies with the machine
  • Mac and iOS support means Windows users are out of luck
  • Privacy depends on configuration, so check what is enabled by default

Pros & cons

✓ What we like

  • Local-first approach to documents
  • Built for sensitive material
  • Works across Mac and iOS
  • Writing grounded in your own files

! What to watch out for

  • Platform support is limited to Apple devices
  • Local index needs its own backup

FAQ

How is it different from a chat assistant?

It is built around a private knowledge base and local indexing rather than general questions.

Which devices work?

Mac and iOS are the supported platforms.

What belongs in it?

Personal notes, work documents and material you would rather not upload, once you have checked the privacy settings.
