Noema Extractor — lightweb.it

Noema – Page Extractor
Most of what you read online disappears. You close the tab, and it's gone — no structure, no memory, no way to connect it to anything else.
Noema changes that. Instead of saving a link or copy-pasting text, you send the whole page — and it arrives in Noema already decomposed: not as a wall of text, but as a tree of atoms, each one a minimal, self-contained unit of meaning.
How it works

Open any article or page in Chrome.
Click the Noema extension icon.
Hit "Extract & Send to Noema."

That's it. The extension extracts the readable content using Readability.js, strips away ads and clutter, and sends the clean text to Noema running on your machine. A new session opens on the canvas automatically.
What happens in Noema
Depending on the parser mode you've configured, the content is broken down in different ways:

Syntactic mode — structure is extracted from HTML and Markdown headings and bullets. No AI involved, instant results.
Semantic mode — a lightweight AI model (Claude Haiku) decomposes the content into meaningful atoms, even when the source has no clear formatting.

Every atom lands on Noema's infinite 2D canvas. You can expand any atom further, navigate by clicking, zoom in and out, and explore the structure spatially — not by scrolling through a wall of text.
Everything stays local
Noema runs entirely on your machine. Your content is stored in a local SQLite database. AI calls go directly from your desktop to the model provider — no intermediary, no cloud storage, no data collection.
Requirements
This extension requires Noema desktop (v0.2 or later) to be running on the same machine. Noema is available for Windows and Linux at noema.tools.
