About Obsidian Smart Connections
Smart Connections is a plugin for Obsidian that surfaces related notes and passages beside the note a user is working on, without needing a search query or existing links. It is the flagship of a family called Smart Plugins, which the site describes as independent third party plugins for Obsidian.
The core plugin builds an index of the vault and uses local embeddings by default, so it needs no API key. A Connections view shows related notes beside the current note, and footer connections show them at the end of it. Smart Lookup starts from a question instead of a note, Smart Context lets a user choose and review the sources attached to an AI request, and Smart Chat Core saves a link to an AI conversation inside the note so the work can be resumed. Smart Graph, a Pro feature on Obsidian desktop, groups notes by semantic similarity whether or not they are linked, giving a map of the vault by meaning.
The intended user is someone with a growing vault of research, decisions and AI drafts who wants earlier material pulled into the next task. The site also carries a searchable FAQ hub covering privacy, API keys, mobile use and Pro.
Smart Connections Core is free, and other Smart Plugins listed as Core are also free. Pro capabilities are sold separately, but the site does not show Pro prices, because there is no pricing page, so the cost of Pro is not listed.
