Private AI workspace

Powerful AI for your team.
Without the cloud.

Why teams choose Aether

Cloud AI stops right where your most useful work begins.

For a lot of teams, the work that would benefit most from AI is exactly the work they cannot paste into a cloud chatbot. Stratos Aether gives them the same capabilities, running quietly on hardware they already control.

The usual trade-off

Send your data out, and hope

  • 01 Your prompts and documents go to someone else's servers
  • 02 You rely on their retention and training policies holding
  • 03 HIPAA, SOC 2 or client privilege quietly rule it out
  • 04 One more vendor lands on the data-flow diagram
With Stratos Aether

Keep your data, keep the capability

  • Runs on your Macs, servers or private cloud
  • Local models by default, a provider key only if you want one
  • Encrypted, self-hosted backups you control
  • An open-source core your security team can read
How it works

Up and running in an afternoon.

No infrastructure project. Install it, point it at a model, and your team is working privately the same day.

01

Install it

Download the app, or run one command. It sets itself up on your hardware, no cloud account required.

02

Connect a model

Run a local model, or paste a provider key. The guided setup walks anyone through it in a couple of clicks.

03

Get to work

Chat, research, triage the inbox, draft documents. All in one place, all on your machine.

Connecting a model is two clicks, local-first by default.
Everything in one place

A real workspace, not a chatbot in a box.

Chat and agents are just the start. Aether brings your research, inbox, calendar and documents together, so your team stops switching tabs and starts getting answers.

Chat and agents

Have a conversation, or hand off a whole task to an agent that uses tools. Always running locally.

Your models

Run open models on your own hardware through the built-in Cookbook, or connect a provider key.

Deep research

Send it a question and get back a clear, multi-step answer with the sources it actually used.

Email

Connect any inbox over IMAP and SMTP. Aether summarizes long threads and drafts your replies.

Calendar

CalDAV and .ics, so your schedule sits right next to the work instead of in another app.

Memory and skills

A private knowledge layer that remembers your context and picks up reusable skills as it goes.

Compare

Ask the same question of several models side by side, and keep the answer you trust.

Documents and gallery

Write documents and edit images right in the app, with version history and AI help on tap.

Notes and tasks

Capture quick notes, set reminders, and schedule jobs the agent can pick up later.

Security and control

Private by design, not by promise.

Every decision here points the same way: keep your data on hardware you control. That is what makes Aether a fit for the most sensitive teams.

On your hardware

Models and data stay on your machines. Nothing is sent to a third party by default.

Encrypted vault

AES-256, self-hosted backups. Your passphrase and keys stay with you.

Real access control

Admin accounts, two-factor auth, API tokens and per-user privileges.

Open and auditable

An open-source core your team can read, verify and host with confidence.

Who it is for

Made for teams that keep sensitive data close.
