AI topic filtering

AI sends eligible feed content and your topics to OpenRouter and its providers. Only enable it for feeds you are comfortable sharing.

One topic per line.

When AI finds a match

OpenRouter connection

Use Save API key to update the connection separately from your other settings.

Advanced options

Sends eligible pictures to the image provider and can add cost.

Limits reset at midnight UTC and are split between www and Old Reddit. Set a spending limit in OpenRouter for a firm cap.
