Meet Clicky · Your Agentic AI Tutor

Your tutor doesn’t just chat — it takes the keyboard

Clicky lives inside your code editor. Ask for a walkthrough and it gets up from its corner, flies to your code, and builds the solution line by line — explaining every move like a teacher at a whiteboard. Then it hands the keyboard back to you.

  • Notices when you're stuck. Go quiet for 45 seconds and Clicky checks in — with a hint drawn from your actual code and failing tests, never a canned tip.

  • Writes code in your editor, live. Watch the solution appear keystroke by keystroke, one small step at a time, with the reasoning behind every line.

  • Teaches with a real voice. Turn on voice and Clicky talks you through each step — then leaves the full explanation as comments in your code to read back.
