Honest framing first: TextSight does not ship a native desktop app yet. There is no .dmg for Mac, no .exe or .msi for Windows, no .deb or AppImage for Linux. The product is web-based and runs in every modern desktop browser, and the Chrome extension extends it into Gmail, LinkedIn, ChatGPT, and most webpage editors. For heavy desktop writers (researchers, content writers, developers, dissertation drafters) the browser plus the extension is the working desktop setup today. A native build is on the roadmap; the waitlist link is below for anyone who wants the heads-up when it ships.
Most queries that begin with "ai humanizer desktop" or "ai humanizer for Mac" expect a download. The truthful answer is that TextSight is a web product in 2026. The browser is the canonical surface today, the Chrome extension is the closest desktop integration, and a native build is in planning. This page exists to set the expectation cleanly.
TextSight does not currently package the AI rewriter as an Electron app, a Tauri app, a native macOS Swift build, or a Windows .NET application. There is nothing to download from the website, nothing on the Mac App Store, nothing on the Microsoft Store. Anyone offering a "TextSight.exe" or "TextSight.dmg" on a third-party site is not us; do not run it. The only TextSight surfaces are the web app at app.textsight.ai, the Chrome extension on the Chrome Web Store, the Android app on Google Play, and the WordPress plugin.
The AI rewriter logic runs entirely on TextSight servers, so a native desktop shell would do nothing the browser does not already do. A native build mostly buys you a dock icon and a chrome-less window, which Chromium already offers through Progressive Web App install. Shipping a separate Mac and Windows and Linux build would split engineering effort across three platforms with no improvement to the rewrite quality. The team chose to put that time into the AI rewriter model instead.
A native desktop app would add a real dock icon, OS-level keyboard shortcuts, system clipboard integration, share-target hooks (rewrite from any text selection anywhere on the OS), and a tray icon for quick access. Those are real conveniences for heavy users, which is why the native build is on the roadmap. None of them change the AI rewriter output. If you want the heads-up when the native build ships, the waitlist sign-up is in the roadmap section below.
The web app uses standard web technology with no browser-version gating. If your browser renders Gmail and Google Docs, it runs the AI rewriter.
Chrome, Safari, Firefox, Edge, Brave, Arc, and Vivaldi on Ventura, Sonoma, and Sequoia. Apple Silicon (M1, M2, M3, M4) and Intel Macs both work because the compute runs on TextSight servers, not on your machine. Safari is the system default and works fully for rewriting, scanning, file uploads, and history. Chrome is the recommended browser if you also plan to use the extension. Arc is the favorite of many writers because of the sidebar layout.
Chrome, Edge, Firefox, Brave, and Opera on Windows 10 and Windows 11. Edge is the system default and works fully; Chrome is the recommended option for the Chrome extension workflow. Windows on ARM (Surface Pro X, Copilot+ PCs) runs through ARM-native Chrome and Edge with no compatibility issues. Internet Explorer 11 is not supported; modern ES2020 JavaScript is required and IE has been out of mainstream support since 2022.
Chromium, Firefox, Brave, and Opera on Ubuntu, Fedora, Debian, Arch, Pop!_OS, and most other modern distros. Linux users frequently report that AI rewriter competitors only ship Mac and Windows binaries, leaving Linux out. The web-only path removes that gap completely; Firefox on Ubuntu rewrites exactly the same way Chrome on macOS does, and Linux is a first-class supported platform.
Chromebooks run the web app natively because Chrome is the OS. The Chrome extension installs from the Chrome Web Store on ChromeOS as easily as on any desktop Chrome. School-issued and managed Chromebooks usually allow extensions if Google Docs and Drive are allowed; check with the school IT policy before installing on managed devices.
For desktop writers who cycle between Gmail, LinkedIn, ChatGPT, and a long-form editor all day, the extension takes the friction out of every rewrite. It works on every Chromium browser on every desktop OS.
Install the extension from the Chrome Web Store, sign in once, and the AI rewriter becomes a toolbar icon. Highlight a sentence in any editor, click the icon (or right-click and choose Rewrite with TextSight), pick a mode in the popup, and the rewrite drops back into the editor in-place. About ten seconds end to end. The tab switch and the manual copy-paste step are gone.
The extension uses the standard Chromium extension API, which means the one package on the Chrome Web Store works in Chrome, Edge, Brave, Arc, Vivaldi, and Opera on every desktop OS. Install once from the Web Store and the same extension follows your browser profile across machines. A dedicated Edge Add-ons listing is planned but the Web Store install path covers every Chromium browser today.
Standard text inputs accept in-place rewrites: Gmail compose and reply, LinkedIn posts and messages, Twitter and X compose, ChatGPT and Claude and Gemini chat boxes, Substack and Medium drafts, generic textareas and contenteditable fields across the web. A small number of custom editors (Google Docs iframe, Notion blocks, some ATS systems) fall back to a popup workflow where you copy the rewrite back manually. Honest list, both columns, on the dedicated extension page.
Firefox has its own extension API and the TextSight extension is currently Chromium-only. Firefox users on macOS, Windows, and Linux open app.textsight.ai in a pinned tab and the workflow is paste-in, copy-out. A Firefox extension is on the longer roadmap once the Chromium build stabilises, but the web app already covers the core paste-and-rewrite use.
The interface was designed for a mouse and a wide screen first, then adapted down to mobile. The desktop experience is the canonical one.
On a 13-inch laptop or wider, the scan and rewrite panels sit side by side. You paste once, see the baseline Authenticity Score on the left, hit Rewrite, and the rewrite appears on the right with the new score. Per-sentence highlights show which lines still read AI. The compare view is the workflow heavy editors come back for; phone screens collapse it into stacked panels by necessity, but desktop keeps both views in your eyeline.
Light, Balanced, and Maximum all sit above the result panel as a toggle. Run the same text through two modes back to back and pick the rewrite that reads more naturally in your voice. Balanced is the default for nine pieces in ten; Light is the right pick for technical or research writing; Maximum is for marketing and social copy where voice variation is welcome. All three modes work on every tier including free.
The desktop interface accepts PDF, DOCX, and TXT uploads on the Pro tier (and URL imports). Drag a file into the input, the extracted text fills the input box, and you rewrite the whole document in chunks. For dissertation chapters, multi-section articles, and long research drafts the upload path saves the manual chunking you would otherwise do by hand. The free tier is paste-only; uploads start at Pro.
The web app supports the standard desktop keyboard shortcuts. Cmd-V or Ctrl-V to paste into the input, Cmd-A to select the rewrite, Cmd-C to copy it out. Mode switching is mouse-only today; a keyboard shortcut for the mode toggle is a tracked enhancement. The Chrome extension also respects a configurable keyboard shortcut (default Ctrl-Shift-H on Windows and Linux, Cmd-Shift-H on macOS) for the rewrite trigger.
The web app, the Chrome extension, and the WordPress plugin all share one TextSight account, one monthly word quota, and one billing. Yearly billing saves 25%.

Research, long-form drafts, dissertation chapters, software documentation, marketing pages. The work that needs two windows and a keyboard, not a phone.
Long documents, careful citations, voice that has to stay academic. The desktop web app opens with the scan and rewrite panels side by side, so you can paste a paragraph, see which sentences flag, and rewrite only those without leaving the page. The Light mode is the right pick here; meaning preservation matters more than aggressive rewrite, and Pro on Yearly handles dissertation-scale word counts on a single account.
Long-form drafts in Google Docs, ad copy in a shared spreadsheet, blog posts in WordPress. The Chrome extension rewrites paragraph by paragraph inside Google Docs (via popup fallback) and in-place inside Substack and Medium. The same account quota covers all three surfaces and the desktop wide screen makes the per-sentence highlight evidence readable, which is how most content teams catch the residual AI signature before publishing.
Documentation, internal RFCs, design docs, release notes. The Light mode protects technical terminology and exact phrasing while still breaking the GPT signature on the surrounding prose. The Chrome extension rewrites inside GitHub issue editors, GitLab merge requests, and Confluence drafts as standard contenteditable fields. The browser-only path also avoids the install permissions a corporate dev laptop usually requires.
Landing pages on one monitor, ad copy on another, email sequences on a third. The Chrome extension means one AI rewriter trigger across all three browser windows; the same account, the same monthly quota, the same Authenticity Score. The Maximum mode is the right call for short marketing copy where the AI-stiffness is a real conversion drag and voice variation is welcome.
Honest status check. Here is what a native build would add, what is in planning, and where to register interest.
A real OS-level keyboard shortcut that triggers rewrite on any selected text anywhere on the operating system, not just inside browser tabs. A tray icon or menu-bar item for quick access. System share-target hooks so any "Share" or "Services" menu can pass text into the AI rewriter. Native file drag-and-drop with batch processing for multi-document work. None of these change the rewrite quality; they change how cheap it is to invoke a rewrite during a writing session.
Three reasons. Native means Swift on macOS, .NET or WPF on Windows, and Flatpak or AppImage on Linux. Each shell is weeks of engineering and ongoing maintenance burden, with auto-update infrastructure to build on every platform. The team chose to ship a tighter web product, a stronger Chrome extension, and a measurable improvement to the AI rewriter model first. Native packaging comes after that work lands.
If you want the heads-up when the native desktop app ships (and to be early in the beta queue), sign up for a free TextSight account and email support at the address in the footer asking to be added to the desktop-app waitlist. We will email you when the macOS build hits private beta first, then Windows, then Linux. No spam, one email per major milestone.
Web app in a pinned tab for paste-and-rewrite and for file uploads. Chrome extension on Chromium browsers for one-click rewrites inside Gmail, LinkedIn, ChatGPT, Substack, and most editors. WordPress plugin if you publish through WP. PWA install on Chrome, Edge, or Arc if you want a dock icon and a chrome-less window without waiting for the native build. All four surfaces share one account and one monthly quota.
