Copilot Plus Alpha is here! I've been working on this for a long time! Test license key is on its way to project sponsors and early supporters.

Time-based Queries: Ask questions like Give me a recap of last week @vault or List all highlights from my daily notes in Oct @vault. Copilot Plus understands time!
Cursor-like Context Menu: Enjoy a more intuitive and streamlined context menu specifically designed for Plus Mode. It not only shows note titles but also PDF files and URLs!
URL Mention Capability: Quickly reference URLs in your chat input. Copilot Plus can grab the webpage in the background!
Vault Search with Cmd + Shift + Enter: Search your vault with a simple keyboard shortcut, this is equivalent to having @vault in your query.
Dynamic Note Reindexing: Copilot index is updated at note modify event under Copilot Plus mode (this is not the case in Vault QA basic mode), ensuring your data is always up-to-date.
Image Support in Chat: Add and send image(s) in your chat for any LLMs with vision support.
