# Welcome to Subs
[**subs.fun**](https://www.subs.fun/) is an app to trade, post, and earn in tokenized internet subforums ("subs").
A sub is a subforum with a coin, and has a custom AI agent ("subagent") that works for it. Subagents learn from content posted in the sub and reward members for their contributions.
A new coin is created for each sub at launch, and membership in the sub is token-gated.
Members curate a subagent's knowledge with links, posts, and upvotes. The more upvotes a post receives, the more the subagent will weight its contents in its knowledge base. Members are awarded sub coins for posting good content and high-quality engagement.
