Quick answer
Choose Copilot when you want one assistant inside Obsidian for chat, Vault QA, commands, writing, projects, web and media workflows, and agents.
Start with Smart Connections when you want related notes from the note you are already working on before asking an assistant. Use Smart Lookup when the question is the starting point. Use Smart Context when found notes should become reusable AI input. Use Smart Chat Core when the provider thread should stay attached to the note it serves.
The Smart workflow is complete only when the work-owning note improves from a reviewed result, not merely when retrieval, copied context, or model output exists.
Current note → Connections
Surface related notes from the note you already have open.
Question → Lookup
Ask naturally when you remember the idea, not the exact words.
Exact phrase → Obsidian search
Use native search for exact words, filenames, headings, tags, syntax, or regex.
Reusable set → Context
Copy only the sources the assignment needs before sending them to AI.
Durable thread → Chat
Save provider thread links and active/done state in the note they serve.
