I have been exploring the 3schools Copilot drawer inside the 3schools Post Editor. Initially, I thought it was just a standard chat window like ChatGPT where you ask questions, copy the text, and manually paste it into your article.
But yesterday I noticed that Copilot actually has direct control over the editor canvas:
- When you highlight a paragraph and open Copilot, it locks that paragraph as a Target Block and gives you a yellow button to replace that specific block automatically.
- It seems you can type commands in chat to change settings like labels, scheduled dates, and comments without touching the sidebar menus.
- The Pen icon opens a full drawing canvas that sends visual sketches to the AI.
Can someone share the most useful chat commands, and how you use the drawing whiteboard to generate complex blocks like comparison tables or math formulas?

How do you actually use 3schools Copilot to control the Post Editor?
Copilot is wired directly into the editor's JavaScript engine. It doesn't just give you text suggestions - it can physically execute actions across your post settings.
Here are the best natural chat commands you can give Copilot:
Change Labels: Type "Set labels to Tech, Android, AI" → Copilot automatically formats the tags array and updates your labels in the sidebar.
Set Schedule / Custom Date: Type "Schedule this post for tomorrow at 6 PM" → it turns on the custom date toggle and sets the exact datetime-local stamp.
Configure Comments: Type "Disable reader comments on this post" → it switches the reader comments setting to Don't Allow.
Trigger SEO Audit: Type "Run SEO check with focus keyword 'Google Discover Tips'" → it fills in your focus keyword, opens the SEO tab, and runs the live percentage score gauge.
Save or Preview: Type "Save this as draft" or "Open preview" → it executes the action immediately.
Here is how to use it properly:
1️⃣ Click on any weak paragraph, headline, or table in your article.
2️⃣ Look at the bottom of your screen: a floating pill bar appears with quick buttons (Rewrite, Expand, Grammar, and a purple button labeled Edit with AI).
3️⃣ Click Edit with AI.
4️⃣ Copilot opens with a blue box on top showing your target block.
5️⃣ Type whatever change you want (e.g. "Make this intro sound more exciting with a bulleted list").
When Copilot responds, you will see two buttons below the preview:
👉 Insert at Cursor (Blue): Drops the new content at the bottom.
👉 Replace Selected Block (Yellow): Directly swaps out the old paragraph for the new one without breaking the surrounding layout!
When you tap the Pen icon in Copilot, you get a full black canvas with color picker, brush size slider, and undo controls.
Because Copilot connects directly to Gemini's multimodal vision model, it can actually "see" and interpret hand-drawn sketches.
Two great ways to use it:
1| Handwritten Formulas: Draw a complex fraction, square root, or matrix with your finger → tap Attach Drawing to AI → type "Convert this math drawing into a KaTeX formula block".
2| Flowcharts & Wireframes: Draw a rough 3-box diagram with arrows → attach sketch → type "Write a step-by-step numbered checklist block matching this diagram".
You can also click the Image upload button next to the chat input to upload screenshots of competitor charts, infographic snippets, or data graphs for instant analysis.
When you open Copilot inside a blog post, the editor loads your blog's archive database in the background.
If you type: "Scan my draft and insert contextual links to my published articles", Copilot reads your text, identifies matching topics, and injects clean anchor links pointing to your actual live Blogger URLs. You don't have to go searching through your old posts to copy links manually!
