Bluesky uses an algorithmic recommendation system to power its Discover feed, surfacing posts based on a user's engagement history, social graph proximity, and network-wide trending signals.

Launched in July 2023 as a replacement for the simpler 'What's Hot' feed, the Discover feed mixes trending content with posts from accounts a user follows and accounts near their social graph. Bluesky's official blog states the feed is 'customized for what you like to see.' Since May 2024, users can further tune the feed using 'Show more like this' and 'Show less like this' controls on individual posts. In October 2025, Bluesky began testing a 'social neighborhoods' ranking layer that prioritizes replies from people a user already interacts with or is likely to know. Bluesky confirmed in November 2024 that the Discover feed uses AI, but stated it is not a generative AI system trained on user content.
