FAQ

How does BlinkWrite read what I'm writing?

BlinkWrite reads the text around your cursor to understand context: the active input and its surrounding context, such as a conversation thread, email chain, or document. It only reads the text it needs to make a suggestion; it isn't monitoring your screen or tracking your activity. See How it works.

Is my data sent to the cloud?

The text context is processed by our customized, self-hosted AI models on our own infrastructure. Your data never passes through third-party AI APIs. Before anything leaves your machine, an on-device model masks personal information like emails, phone numbers, and credentials. See Privacy & security.

Is my writing stored or used to train your models?

No. Your text is never saved, logged, or retained. Each suggestion is generated in the moment and discarded. Your writing is never used to train or fine-tune any model.

Does BlinkWrite work in every app?

Rephrasing works everywhere you can type — any macOS text field, in any app, plus every major browser (Chrome, Safari, Brave, Firefox). Proactive drafts, completions, and corrections read the surrounding conversation or document, so they're available in apps BlinkWrite understands: Slack, Gmail, Discord, WhatsApp, Notion, and more. See Supported apps.

How is this different from standard autocomplete?

Standard suggestions predict the next few words from what you've typed. BlinkWrite reads the entire conversation context (who messaged you, what they said, and the tone of the thread) and drafts contextually appropriate replies, completions, corrections, and rephrasings.

How is BlinkWrite different from Grammarly?

Grammarly + Superhuman Go is a broad, cross-platform editing and AI suite. BlinkWrite is a focused Mac writing assistant that drafts replies before you type, completes sentences inline, and accepts every suggestion with Tab. See the full BlinkWrite vs Grammarly + Superhuman Go comparison.

Will AI-generated suggestions sound like me?

Yes. BlinkWrite reviews your past emails to learn your tone, vocabulary, and style. Drafts reflect how you actually write. You review every one before it goes out and you're always in control of what gets sent.

Does BlinkWrite send replies automatically?

No. BlinkWrite will never send a reply on your behalf. Every draft sits in the input for you to review, edit, and send when you're ready.

Can I control when BlinkWrite is active?

Yes. You can pause and resume BlinkWrite at any time from BlinkWrite's eye icon in the menu bar, the strip at the very top of your screen, on the right among the status icons. See Where to find BlinkWrite for a diagram. Suggestions only ever appear in a floating popup. They never change your writing until you press Tab to accept. See Controls & shortcuts for the full list of options.

What languages does it support?

36 languages, including English, Spanish, French, German, Japanese, Korean, Chinese, Arabic, and many more. BlinkWrite automatically detects the language you are writing in and suggests in the same language by default. Custom rephrasing can translate your paragraph into a language you specify. See the full list in Models & languages.

How does rephrasing work?

Double-tap Tab to improve the current paragraph. Below the result, click Shorten, Improve, Formal, Friendly, or Custom. The same modes are available through Shift + 1 to Shift + 5, in that order. Each mode uses your original paragraph and the same available context.

Custom opens an instruction field below the modes. Type your instructions in that field. Press Enter to request the rewrite. The cursor stays in the field so you can edit the instructions and submit them again. Press Tab to apply a changed result, or Esc to close the dialog.

If the preview matches your current text, it uses the inactive text color and shows a checkmark instead of Tab. There is no change to apply. See the rephrasing guide for examples.

Is BlinkWrite free?

BlinkWrite offers a free trial to get started. After that it's a paid Pro subscription. See Billing & plans.

Which devices does BlinkWrite work on?

BlinkWrite runs on Apple silicon Macs (M1 or later), on macOS 26 or later. A Windows version is in the making.
