How it works

BlinkWrite's suggestions are good because they're grounded in context: the actual conversation, thread, or document you're writing in. Here's how that works, end to end.

1. Reading context

BlinkWrite reads the text of the active field and its surroundings: the messages above your reply box, the email thread you're in, or the document you're editing. Wherever possible it uses the macOS Accessibility API, the same system feature assistive tools use. That surrounding thread or document is the context BlinkWrite draws on to make suggestions sound right.

Importantly, BlinkWrite:

Reads only the text it needs to make a suggestion.
Isn't monitoring your screen or tracking your activity.
Only looks at the app you're actively writing in.

For popular messaging and email apps, BlinkWrite understands the structure of a conversation: who said what, whether it's a one-on-one or a group, and which message you're replying to.

2. What gets changed

Reading context is broad; applying a suggestion is narrow. Completions, corrections, and rephrasing only change the current paragraph — the block of text where your cursor sits, bounded by hard line breaks (when you press Return or Enter). BlinkWrite uses the wider conversation or document to decide what to suggest, but when you accept one of these, only that paragraph is updated. Everything else in your message or document stays exactly as you wrote it.

3. Masking personal information on your device

Before anything leaves your Mac, an on-device step scans the text and masks personal information: things like emails, phone numbers, credit card numbers, addresses, and credentials. This happens locally, on your machine, and the masking is reversible only on your device so the final suggestion reads naturally. See Privacy & security.

4. Generating a suggestion

Your masked draft and any masked surrounding context are sent securely to BlinkWrite's customized, self-hosted AI models, running on our own infrastructure. They never pass through a third-party AI provider. The model produces a suggestion appropriate to what you're doing: a full reply, a completion, a correction, or a rephrase. See Models & languages.

Your text isn't stored or logged, and it's never used to train models. The suggestion is generated in the moment and then discarded.

The suggestion comes back and appears in a small floating popup right next to where you're writing. It's a preview you can accept with Tab or ignore by continuing to type. Nothing is changed in your document until you accept.
