Tutors 2

Learn by doing — leveled, gamified tutors that adapt to you.

code-tutor

Canvas

Turns the current codebase into a personal CS course: extracts the algorithms, data structures, complexity and theory in your code, explains each at an adjustable level (ELI5 to Wizard), points at real files with syntax-highlighted code, tracks what you understand, and reviews good/ok/bad spots with a path to fix them.

language-tutor

Canvas

Pick a language and a gamified course appears — flashcards, quizzes, XP, levels, streaks, hearts, gems, mascots and confetti, plus AI example sentences for any word. You and the agent share one learner profile.

Live & discover 3

Shared, auto-refreshing dashboards and a personalized discovery feed — each with a one-tap AI summary.

Canvas

A personalized live stock watchlist — shared between you and the agent, with live quotes, sparklines, and an AI market summary of what's moving.

news-aggregator

Canvas

Pick a topic or free-text search and get a live, shared news feed (Google News, no API key). Save/favorite/hide items, search history, pin searches as custom topics, sort & filter, visible-only auto-refresh — plus a one-tap AI TL;DR digest of the current headlines.

wiki-discover

Canvas

A “for you” Wikipedia reader shared with the agent — pick interests (or thumbs up / meh / not-for-me each article) and it learns your topics and surfaces popular articles you'll find interesting, with article images, a live preference profile, and an AI TL;DR per article.

Just for fun 1

A little delight, on demand.

Canvas

Roll the dice to discover a random animal and a fun fact — with bounce-in animations, floating emojis, roll history, and a “Tell me more” AI fun fact.

Install one

Install from inside Copilot — in the app or the CLI, just ask the agent (or hit Copy install prompt on any extension above and paste it into Copilot):

install the stock-ticker canvas from jongio/copilot-extensions/extensions/stock-ticker

Copilot fetches the folder into ~/.copilot/extensions/, reloads, and it's ready — no clone, no flags, no build step.
