Copilot AI Productivity Suite: saves prompt snippets and inserts them from VS Code
Copilot AI Productivity Suite is made by the team that publishes this site. Typing #copilotsuite /snippet_id inserts the exact saved snippet template into the conversation. [2]
Snippets can sit in nested folders, and you can bundle several into a group that is referenced all at once. [2] Placeholders like ${name} or ${name:default} ask you for a value when the snippet is inserted. [2] You can pin up to five favorite snippets to the VS Code status bar. [2]
A bundled local MCP server (MCP is a standard way for AI assistants to use other programs) makes your snippets and groups available to Claude Code, Codex CLI and other MCP clients over stdio. [2] If you turn it on, each snippet is written out as a slash command file for Claude Code and Codex CLI, and the files stay in sync as you edit. [2]
You can export snippets as JSON or make a share link, and teammates can import it. [2] You can also select several snippets and move them, delete them or insert all their references at once. [2] Copilot toolsets, custom agents, instruction files and prompt files can be created and edited from the sidebar. [2]
There is a Free plan at $0 that allows 20 Copilot insertions a week. [2] Premium costs $6.99 a month and has unlimited Copilot insertions. [2]
If you sign in with an account (emailed one-time code), your snippets, groups and settings sync across your machines. [2] The extension uses a proprietary licence. [2] While VS Code telemetry is on, it sends anonymous usage statistics, but never snippet content. [2]
It is a VS Code extension that needs VS Code 1.116.0 or newer, and it is also on Open VSX for Cursor, Windsurf and VSCodium. [2] You install it from the VS Code Marketplace as LunarWerx.copilot-suite. [2]

If you want your own model choice, massCode connects to several providers with your own key, and the provider bills the usage. [1] [1] For any other snippet tool, ask the same questions: which editor, which AI tools, how syncing works, and what the licence says.
