How to Use Arc Codex

Your guide to reading intelligence, understanding analysis, and contributing to the feed.

Reading the Feed

The main feed shows articles collected from 2,087 sources worldwide, analyzed by the A.R.C. framework as they arrive. Each card represents one article with its full analysis inline.

Click any article title to go to the full article page, where all analysis sections are expanded by default.

Understanding the A.R.C. Analysis

Every article is run through three independent AI analytical passes. Expand any section on a card to read it.

Sentinel — AI Content Detection

Sentinel runs a forensic pass on every article to estimate whether it was written by a human or generated by AI. It's tuned conservative — false positives (calling human writing synthetic) are treated as worse than false negatives.

Sentinel is not a spam filter — a SYNTHETIC verdict means the writing pattern resembles AI output, not that the content is wrong or malicious.

Translation

Arc Codex supports 162 languages via the TranslateGemma model running locally on the M1. Translations are cached for 24 hours per article/language pair.

Publishing to Arc Codex

Signed-in users can submit content directly to the Arc Codex pipeline via the Publish page. All submitted content goes through the full A.R.C. analysis pipeline.

Submissions are processed asynchronously — your article will appear in the feed within 1–2 scribe cycles (up to ~10 minutes). Priority queue items are processed first at the top of each cycle.

Every card has a share menu (the arrow icon) with options to copy the link, post to X, share on Facebook, share on LinkedIn, post to Bluesky, or send via email.

Your Account

Arc Codex uses soft authentication — the site is fully public and requires no login. Signing in with Google or GitHub unlocks preferences, publishing, and private articles.
