What's new in JustZix — AI Helper, code search and more

17 May 2026 · by JustZix Team

This is the biggest JustZix update in a while. There's a brand-new AI assistant built into the extension, search bars above every code editor, and a recently rebuilt Output Console. Here's a roundup of what changed and where to read more.

Headline: AI Helper

The big one. AI Helper is an AI assistant built right into the extension — a floating, draggable, resizable window that lives inside the page, per tab. Open it with Ctrl+Alt+\, a button in the popup widget, or the Chrome context menu.

You bring your own API key from OpenAI, Anthropic or Gemini, set in Settings → AI Helper. The chat window keeps conversation history and has provider and model pickers. The model receives the current page context — URL, title and an HTML fragment — so it can actually reason about the page you're on. API calls go through the extension's background service worker, which means your key never reaches the page context and the request bypasses the page's CSP.

AI Helper can do real work — agentic tool-calling

AI Helper isn't just a chat box. It uses tools in an up-to-8-step loop via a provider-independent text protocol, so the same capabilities work on all three providers. The tools let it:

• Inspect the page — query_page (run a selector, get matches and HTML) and list_structure (read your folders, groups and rules).
• Test code live — open_temp_pane and set_temp_pane_code open a TEMP CSS/JS window and insert code, so you watch it work before anything is saved.
• Create things — with your OK — create_folder, create_group and create_rule, each requiring a separate, explicit confirmation.

The enforced workflow is: ask for details → inspect the page → test in a TEMP window → ask you to verify → persist only after you agree. Every action shows up as a chip in the conversation, so you always see what happened.

Code search in the editors

Every code editor now has a search bar above it — the CSS and JS editors in a rule, and the JS editor for actions. It gives you:

• a text input with a search-icon button and an n / total match counter;
• highlighting — all matches in blue, the active match in yellow and scrolled into view;
• ▲ ▼ arrows to navigate when there's more than one match;
• Enter / Shift+Enter for next/previous, Esc to clear;
• global shortcuts: Ctrl+Alt+←/→ to step through matches from inside the editor, and Ctrl+Alt+F to jump focus to the search field.

For long rules, it's the difference between scrolling and just jumping.

Recap: the rebuilt Output Console

If you missed it earlier, the Output Console was rebuilt into a 6-tab log and inspection viewer — an in-tab developer window for debugging your rules without DevTools. The six tabs cover console logs, errors and other output, including a Network tab and a DataLayer tab for inspecting analytics pushes. It pairs naturally with the JS pane and JS Console.

The bigger picture

Put together, JustZix now covers the full loop: AI Helper proposes and tests changes, the code editors (with search) let you refine them, and the Output Console lets you debug the result — all inside the page, no DevTools, no account. The extension stays free and works on Chrome 100+, Edge, Brave, Opera and Vivaldi.

How to get the update

1. Update the extension to the latest version.
2. Open Settings → AI Helper and add an API key for OpenAI, Anthropic or Gemini.
3. Open a page, press Ctrl+Alt+\, and ask AI Helper to build a rule.
4. Open any rule's CSS or JS editor to try the new search bar.
