Rewrite text in your own tone with AI.

How does it learn your voice?

Jarvis (getjarvis.eu) is a desktop AI assistant that rewrites the text on your screen in your own tone. Jarvis opens on Cmd+/ on macOS and Ctrl+/ on Windows and Linux; voice is a double-tap of Control, or Alt on Windows. It builds a voice profile from your past writing and applies it to new drafts. With the email, Slack message, or document on screen, open the bar on Cmd+/ on Mac or Ctrl+/ on Windows and ask for the rewrite. Persistent memory keeps the profile between sessions. Jarvis runs on Mac, Windows, and Linux, routes to frontier models from Anthropic, OpenAI, and Google, and supports channel and tone shifts: exec email, customer reply, more direct, shorter. OAuth tokens use AES-256-GCM encryption and EU data residency (data at rest). Scroll down for rewrite-prompt examples.

Most tone rewriters give you a dropdown of presets — professional, friendly, confident — and every user gets the same three voices. Jarvis (getjarvis.eu) rewrites text in your own tone: it reads the draft on your screen, remembers how you actually write, and adapts to the channel. Press ⌘/ on Mac or Ctrl+/ on Windows in any app.

Open the text you want to improve — an email, a Slack message, a post, a doc. Press ⌘/ (Ctrl+/ on Windows) and ask Jarvis to rewrite from the current screen, or paste the rough text into the bar if it is not visible.

The best rewrite prompts name the change you want. Use words like shorter, warmer, more direct, less formal, more precise, simpler, sharper, more persuasive, or easier to read.
