Ghostwriter by MyHandler is an AI writing assistant for Windows 10 and 11 that drafts text directly at your cursor inside any application. Rather than asking you to describe what you want written, it reads the screen in front of you — the thread above your cursor, the question beside it, or the half-finished sentence inside it — works out what you would write next, and types that draft in your voice. The site describes the entire interaction as a double-tap: put your cursor in any text field, double-tap the hotkey, and the text appears. It is designed for people who write replies all day and want the first draft to arrive already written instead of having to prompt an AI for it.
The problem Ghostwriter targets is stated plainly on its own site: every other AI writes what you tell it, while Ghostwriter writes what you already know. The friction it removes is not the writing itself but the prompting — describing what you want written was the work you were trying to avoid, and describing a reply in a live conversation is often more effort than typing it would have been. Ghostwriter replaces the prompt with the context already on your screen, so the screen content becomes the entire input. Because automatic writing carries the risk of sending something you did not intend, Ghostwriter also stops short of the final step: it types into the box and never sends anything itself. You edit it, you send it.
The core feature is screen-context drafting. When you double-tap the hotkey, your Handler captures the screen around your cursor — the thread above it, the question beside it, the half-finished sentence in it, the form, or whatever is in front of you. That capture is the input. Before writing a single word, Ghostwriter works out what kind of writing this is: a reply owed in a thread, a sentence to continue from exactly where it stops, a blank box under a question that wants a real answer, or a message the context obviously calls for. The site states that getting this right is most of the job, so it decides on the kind of writing before it drafts anything. This matters because a continuation that restates your own sentence, or a reply that summarises the thread back at you, would be worse than useless.
Ghostwriter also handles the social detail of a conversation. It maps each message to its sender, works out which handle is yours, and tracks who asked whom for what, so it answers the other party rather than replying to your own words. It matches how you write to that person, down to the sign-off. The result is a draft that reads like something you would have written to that specific person in that specific thread, not a generic assistant response that you then have to rewrite from scratch.
Two further capabilities shape the draft. First, scheduling safety: if the reply proposes a time, it is checked against the next two weeks of your calendar first, and the product states that it will not double-book you. A connected calendar is required only for this scheduling cross-check — the site notes that everything else works without one. Second, rewriting: if you select text before double-tapping, Ghostwriter rewrites the selection instead of composing a new reply, so the same single gesture covers replying, continuing, filling in, and rewriting existing text.
Ghostwriter is part of the MyHandler desktop app for Windows. The workflow the site describes has three steps. First, you put your cursor where the words go — no prompt, no dictation — and double-tap the hotkey so the Handler captures the screen around that cursor. Second, the Handler decides what kind of writing this is and, if the reply proposes a time, checks it against your calendar. Third, the text appears at your cursor exactly as written, with nothing sent. On privacy and data handling, the capture around your cursor happens on your machine, against the encrypted vault on your PC. The assembled context is then sent to the company's cloud model, which the site says operates with zero data retention, to write the draft.
The stated benefits follow from that design. There is no prompt to write, because the whole interaction is a double-tap and you never have to describe what you want. It reads the situation, not just the words, identifying whether the moment calls for a reply, a continuation, a fill-in, or a composition from scratch before it writes. It gets who's who right, so it answers the other party rather than your own messages. And the last step stays with you: Ghostwriter types the draft and stops, so nothing leaves your machine without your decision. These benefits combine into a simple outcome — the first draft of a reply appears at your cursor in your voice, and you spend your time editing rather than composing.
The use cases are anchored in the places people actually write. The site names a mail client, Slack, a browser form, and a comment box as examples of any app where a cursor in a text field is enough. In practice, that covers an email reply owed in a thread, a chat message that needs answering, a sentence you want continued from exactly where it stops, a blank box under a question that wants a real answer, a message the context obviously calls for, and a scheduling reply that has to respect your next two weeks of calendar. Because the input is whatever is on screen, the same double-tap works across all of them without switching tools or re-describing the task. Selecting text first turns the same gesture into a rewrite rather than a continuation.
Ghostwriter runs on Windows 10 and 11 today and is free for those platforms. The site states that macOS and Linux are coming, and offers to email you the download link so it is waiting when you are at a Windows PC, with a direct download for Windows also provided. A connected calendar is optional and used only for the scheduling cross-check. MyHandler offers related capabilities built on the same local-vault foundation: Dictation, which lets you hold a key, talk, and release so your words appear at the cursor and which keeps working with Cloud AI switched off; AI Gatekeeper, which watches every channel you connect and screens the noise on your own PC; Contact Intelligence, which builds living contact profiles automatically on your machine from the messages, meetings, and activity already in your vault; and Daily Briefing, a morning briefing written from the data on your own PC.
Ghostwriter's value proposition is that the draft is already there. You do not type a prompt, you do not dictate, and you do not describe the reply you want. You put your cursor in the text field, double-tap, and a reply written in your voice, grounded in the thread on your screen, appears where you were about to type — calendar-checked if it proposes a time, addressed to the right person, and never sent without you. Stop rewriting the same reply: it drafts, you decide.
