How to keep notes while reading in Safari

Updated November 2026 · from the developer of ContextFlow

You read something worth keeping. A week later you can't find the page, or you find it and don't remember why it mattered. Here's what your iPhone already gives you for this, and what ContextFlow does differently: it keeps your notes next to the pages they came from, with AI answers when you want them.

What's already on your iPhone, iPad and Mac

If you only want to save a link with a line of text now and then, Quick Note is free and built in. Use it.

Notes next to the page, without leaving Safari

ContextFlow is an extension that opens on top of the page you're reading. Its chats work like a notebook:

Open ContextFlow on the page: tap ✦ on iPhone or iPad, or click its icon in Safari's toolbar on Mac (Control-Shift-E).
Swipe the send button up or down (on Mac, scroll on it or hold it). It turns into “Save note”. Write the note and save it.
Keep reading. The same chat carries on to the next page, and the note stays with the page it came from.

Notes are free and use no answers. In the same chat you can ask the AI about any page whenever you like: summarize it, explain a term, translate a paragraph. Each chat lists its pages, so you can tap one and go back to it.

So one chat holds the pages you read, the answers you asked for and your own notes. It's your notes and your browsing history on one topic, in one place.

Ask about your notes later

Turn on Whole chat before you ask, and the answer takes everything in the chat into account: every message, your notes, and the other pages of the chat. That's how you get answers like:

With Whole chat off, answers use the last few messages and the page you're on, and your notes stay out of the request.

Where this helps

On all your devices

Turn on “Sync chats with iCloud” in ContextFlow's settings, and a chat you start on iPhone continues on your iPad and Mac. Chats are end-to-end encrypted in your iCloud and never stored on my server. To share notes, pick the messages you want and send them as plain text with the page links.

Questions

Do notes use up my answers?

No. Notes are free. Only questions to the AI count as answers.

Are my notes sent anywhere?

Not when you save them. They stay in the chat on your device, and in your iCloud if sync is on, end-to-end encrypted. A note goes to the AI only when you ask a question with Whole chat turned on, because then the answer takes the whole chat into account.

Can I get my notes out?

Yes. Share a chat, or pick the messages you want, and it comes out as plain text with the page links.

Does it work on Mac?

Yes. On Mac, ContextFlow is a sidebar in Safari. To write a note, scroll on the send button or hold it.
