Capabilities

Designed for Infinite Scaling.

Keyboard Driven Everything

Never touch your mouse. Invoke the prompt via ⌘K, find articles, query semantically, compile drafts, and organize tags instantly.

Bidirectional Autolinking

Writing [[Idea]]creates a new file if it doesn't exist and links them bidirectionally. Track backtracking pathways seamlessly.

Offline & Local First

Your brain isn't rented from Verisign. Notes are stored locally on your device as standard, plain-text markdown. Easily readable by standard shell utilities forever.

Philosophy

The Anti-Category Manifesto

"The structure of folders implies an answer before the question has even been formulated. Networked thought means building connections as you discover them, creating meaning through association."

Most notebook software forces you to pick a folder for your note. This creates an immediate cognitive hurdle: Where does this belong? In marketing? Under books? Or under journal?

With Aether, you just create a page. Link it to relevant things as they pop up. As connections build, structure naturally crystallizes. You discover hidden pathways in your own thought patterns. It is an extension of your memory, operating as a biological neural web.

Own your thoughts, completely.

We believe knowledge tools should be utility tools. No venture funding, no data telemetry, no lock-in. Aether is built by a small team dedicated to pure thinking systems.
