Power Copilot — Supercharge Copilot/M365

About

Power Copilot transforms Copilot into a development workspace with IDE-level capabilities. Its core features include Custom Chat Folders for organizing sessions and setting default pinned chats, Instant Shortcuts using the backslash for autocompleting reusable prompt templates, and a Side-by-Side Diff view for line-by-line comparison of code changes. The Full-Width Canvas expands to the full viewport for wide content like tables and code. A Local PII Guard automatically masks private data such as emails and card numbers before transmission, and a Token Budget tracker monitors usage while allowing exports to Markdown or JSON. The entire tool operates 100% client-side with no tracking, ensuring all data remains locally stored.
