Edyt is a lightweight desktop application for Mac and Windows that adds AI actions to any text field. Select text anywhere, press a shortcut, and the result appears right where your cursor is. It is designed for people who write in many different applications—email clients, browsers, notes apps, chats, and documents—and who want help without switching windows, copying text into a separate tool, or breaking their flow. Edyt's stated purpose is simple: bring AI right where you write. The company describes it as an AI text assistant that works inside any app with an editable text field, on both Mac and Windows, with Ubuntu listed as the next platform.
The problem Edyt addresses is that most writing assistance requires leaving the place where the writing actually happens. You copy text, open another app or a browser tab, paste it in, get an answer, and then copy it back. That interruption is especially noticeable when the text cannot easily be selected at all—a scanned PDF, a screenshot, or a shared screen. Edyt's tagline puts it plainly: AI for text you can't even select. By living inside the apps people already use, and by offering a way to read text from images on the device itself, Edyt aims to remove the copy-paste round trip and let people get an answer, a correction, or a better phrasing without leaving their work.
The Rewrite action polishes tone, grammar, and clarity in place. According to Edyt, Rewrite keeps your tone and follows your instructions, so it is not limited to correcting mistakes—it can also adjust how something sounds while preserving the writer's voice. Proofread takes a different approach: every issue is flagged in place and grouped by kind on the left, so the user can see what kind of problems were found. The arrow keys move between issues, and Enter fixes one; users can also fix them all at once. The result remains editable—after typing, a Re-check catches anything new—and Insert pastes the text back in, formatted, right where it came from. The demo also shows a readability measure such as easy-to-read word counts.
Alternatives is for moments when the phrasing is uncertain. After selecting text and pressing the shortcut, Edyt suggests several ways to say it. A Show another option produces a genuinely new alternative, never a repeat, and the user can move between options with the arrow keys and press Enter to open Insert or Copy. Explain, meanwhile, is built for understanding. Selecting text and pressing the Explain shortcut opens a panel with definitions on the left and the explanation on the right. A follow-up question keeps the conversation going, so users can dig deeper into the same passage without starting over. The product demos show this with technical language such as a SOC 2 Type II attestation being explained in plain terms.
Translate lets a user select a message and render it in another language. The demo shows a chat in Spanish being translated into English, and the reverse workflow: select a message, pick the language, and insert the result into the reply box before sending. Edyt also lets users ask how to adjust a translation if it is not quite right. Use Prompt is the customization layer. Pressing its shortcut runs your last prompt right away. A library on the left lets you pick another prompt, and personalized prompts remember how you like things phrased. Asked to rewrite a weekly sync draft, the demo produced progressively stronger versions, and the Insert action drops the result straight into the document without retyping. Saved prompts run on anything you select and follow your account to every machine.
One of Edyt's distinctive capabilities is reading text that cannot be selected. If the text is in a PDF, a screenshot, or on a shared screen, the user can hold Option (Alt) and drag over it. Edyt reads it on the device, using Apple's built-in recognition on Mac and the built-in Windows OCR on Windows. The image never leaves the device. On Mac this uses the Screen Recording permission, and only to capture the area you drag; Windows asks for no extra permission. Once the text has been read, the same actions apply—Proofread, Alternatives, Explain, Translate, and Use Prompt—so even a scanned lease agreement can be explained in plain language.
Edyt follows a three-step pattern. First, select your text: highlight anything in any app, such as email, docs, or chats, with no copying and no switching windows. Second, press a shortcut: Ctrl+Shift+Space brings up the toolbar, and you pick the action you want. Third, get your result in place: Edyt calls the AI and drops the result right where your cursor is. Each action also has its own shortcut, and every shortcut can be remapped. Users can write their own prompts and organize them in a library from the dashboard. On privacy, Edyt states that text is sent over an encrypted connection for processing and then discarded—never stored, logged, or used to train AI models.
The benefits Edyt claims are straightforward. It removes the need to leave your app or break your flow, and it works across the applications people already write in. It can handle text that cannot be selected, which most writing assistants cannot. It aims to preserve the user's own tone rather than replace it, and it offers a free plan that Edyt says is enough for most people, with no credit card required. There is also a stated privacy benefit: the text is discarded after processing, and screen text is read on the device so the image never leaves the machine.
The demos on Edyt's site sketch several concrete scenarios. One is fixing a grammar-heavy message before sending it to a client. Another is proofreading a personal essay, where errors are flagged in place and can be fixed one at a time or all at once. A third is replying to a Gmail message when the phrasing is uncertain, using Alternatives to find a better way to say it. A fourth is understanding jargon in a work email—the SOC 2 explanation—and asking follow-up questions. A fifth is translating a Spanish chat message and replying in the reader's own language. A sixth is rewriting a weekly sync announcement in a clearer, shorter style. Finally, holding Option and dragging over a scanned lease agreement lets the user read the automatic-renewal clause and ask what it actually means.
Edyt is aimed at people who write in many apps and want AI help without switching tools—knowledge workers, writers, and anyone who sends email, chats, or documents on a Mac or Windows PC. It runs on macOS 12.3 (Monterey) or later, on both Apple Silicon and Intel, and on Windows 10 or later, 64-bit, currently as a beta. It is distributed directly from the website rather than the Mac App Store, because reading and typing text in other apps requires macOS's Accessibility API, which does not work inside the App Store sandbox; the app is signed and notarized by Apple. Edyt is free to download and free to use, with generous daily, weekly, and monthly usage on the free plan and no credit card required. Pro removes the limits for unlimited use.
In short, Edyt is a desktop AI text assistant for Mac and Windows that puts rewrite, proofread, alternatives, explain, translate, and custom prompts inside any app. It keeps the work in place, reads text you cannot select, and treats privacy as part of the design. Free to download and free to use, it is built for people who want AI right where they write.
