Every change. Shared with you.

InTab 4.0 is here - the biggest release ever. What started as a visual HTML/CSS website editor is now a complete productivity new tab: side-by-side AI chat across ChatGPT, Claude and Gemini, an AI writer, one-click screenshots, YouTube summaries, tab & bookmark tools, focus timers, and more - all in the tab you open a hundred times a day.

Coming from InTab 3? Your Website Editor is still right here, and every site edit you saved has been carried over automatically - v4 just builds a whole workspace around the editor you already loved. Lifetime license? It's recognized automatically; just sign in once to restore it across devices.

Control video speed on any site: every video gets a small floating +/- control you can drag anywhere, with keyboard shortcuts and step-size settings in Options -> YouTube.

Responsive device simulator: preview the current page in true-to-life iPhone, iPad and Galaxy frames with real user-agents, synced scrolling and typing, rotation, zoom, and framed screenshots.

CSS validity checker: scan every stylesheet on the page against the official CSS specs and see each issue with its line, property and offending value.

HTML validity checker: validate the page's markup against the HTML standard (with optional accessibility rules), and click any result to jump to and flash the element.

AI screenshot naming works again: "Name with AI" no longer falls back to "Screenshot" and names every capture after what's really on the page. Now a Pro & Max feature with an in-place upgrade on the free plan.

Box-model badges: margin, padding and border values are crisp color-coded badges that merge into one neat pill per side, readable on any page, light or dark.

X-Ray gets its own card in Inspect -> HTML. Flip it on with one switch, pick X-Ray or Outline mode, and dial the opacity to taste.

Inspect tab at a glance: the tab button shows a badge counting active visual tools, and the Box model overlay works the moment the editor opens.

A warmer welcome back: signed-in Pro members now see their profile picture, name, email and a PRO badge on the welcome screen.

Save Assets: Effortlessly save HTML, JavaScript, CSS, images, videos, and more with a single click, streamlining your workflow.

Performance & Tech Stack Tests: Assess website performance using Lighthouse and inspect the Tech Stack with BuiltWith directly within InTab.

Cache Control: View cache files, their sizes, and clear website caches directly from InTab, simplifying maintenance tasks.

Live Logs: Monitor browser logs in real-time directly within your website, eliminating the need to open Chrome DevTools.

CSS Validator: Identify and resolve CSS errors or warnings seamlessly within InTab, supported by integrated Google search for quick solutions.

Screenshots: Capture precise desktop views or simulate any mobile device, with or without frames, facilitating detailed visual documentation.

Visual HTML Tree: Intuitively explore and edit the Document Object Model (DOM) using a new visual representation, enhancing navigation.

JavaScript Code Editor: Utilize a robust JavaScript editor with syntax highlighting and auto-completion, designed to enhance productivity.

Persistent Changes: Maintain CSS, HTML, and JavaScript modifications across sessions, ensuring customizations persist even when InTab is disabled.

CSS State Support: Enhance design workflows with a visual editor that previews CSS states like :hover, :active, and :focus, ensuring comprehensive styling.

Right-Click Menu: Access a new context menu for rapid actions such as hide, delete, duplicate, or copy directly from the page, improving efficiency.

Undo/Redo: Navigate editing history effortlessly with undo and redo capabilities, empowering easy rollback and error prevention.

Wireframes: Control wireframe overlay opacity and display shading boxes or outlines to highlight elements on the page effectively.
