Copus – Curate, Discover, Connect by Handuo

Everyone curates. Every bookmark, every save, every share is a signal about what you find valuable. But until now, the only systems learning from those signals were ad networks building profiles to sell you things.
Copus changes that.
Save anything as you browse with one click. Each save becomes part of your taste graph: a structured, portable profile of what you actually care about.
Organize finds into treasuries (themed collections others can subscribe to). Discover what other curators are saving. Export your entire profile as .md or .csv anytime.
One click connects your taste graph to ChatGPT, Claude, Grok, Deepseek, or Mistral. Your AI stops giving generic answers and starts responding with your interests, sources, and style in mind.
Open source. Your data is yours. Designed as a public good.
Coming soon: monetize your taste graph when people or AI agents access your curated insights.
