FAQ

Questions, answered.

How much does Quill cost?

The Free plan includes 10 uses per day. Pro includes 600 uses per billing cycle for NT$199/month. Subscribe by Aug 31, 2026, 23:59 (UTC+8) and your first month is NT$149; renewals are NT$199/month.

Can I install Quill on a phone or Windows?

Not yet. Quill is currently a macOS-only app. iPhone, iPad, Windows, and Android versions are on the roadmap.

Which Mac apps does Quill work in?

Nearly all of them — Mail, Notes, Pages, Messages, Slack, Safari, Chrome, and more. Quill reads your selected text and rewrites it in place, or shows the result in a panel for read-only apps like PDFs.

Why does Quill need Accessibility permission?

It's how Quill reads your selected text and replaces it in place. You grant it once in System Settings — it takes about 10 seconds. No other data is accessed.

What happens when I use all free credits?

Your 10 free uses reset automatically each day, and Quill shows the countdown in your local time. You can also upgrade from Plan & Usage in Preferences. Portaly securely handles payment; Quill never stores card details.

Was the headline demo calling an API?

No — the demo on this page is scripted to show the interaction. The real app sends your selection to the AI model you configure.

Privacy

Your data never takes a detour.

Content is transmitted only to produce your response. Quill does not store it or use it for training.

Your content is not stored. Quill Cloud sends the request to OpenAI only to produce the response.
No account required. No sign-up, no profile, no data stored on our end.
Privacy-preserving metrics. Only anonymous usage, limit, upgrade, and purchase events are counted.
Clipboard-safe. If Quill needs the clipboard to read your selection, it restores whatever was there before.

Stop copy-pasting into chatbots.

Select text. Press a hotkey. Done — without leaving the app you're in.
