Litmus

About

Litmus runs in the background as you scroll your LinkedIn feed. Each post gets an inline indicator next to the author's name showing whether the post was classified as AI-generated, mixed, or human-written. The classification happens automatically without any extra clicks.

Litmus tracks per-author AI rates over time. The stats page shows every author you have encountered, their post count, and what percentage of their posts were classified as AI-generated. Open the stats page from the toolbar popup at any time.

Authors who cross a configurable threshold — for example 80% AI rate after at least 5 posts — are automatically hidden from your feed. You can also manually blacklist or whitelist any author regardless of their rate. The popup lets you undo auto-hides and manage your lists.

Optional filters let you skip promoted posts, suggested posts, company posts, and "Recommended for you" widget blocks entirely, before any API call is made.
