Everything you read, made easier

Summaries in one tap

Get the gist of long articles, reports and threads as clear bullet points.

Ask the page

“What's the price?”, “Is this source reliable?”, “What should I do next?” — answers grounded in the page.

Explain & translate

Turn jargon into plain words or translate the whole page into your language.

Select text to focus

Highlight a paragraph to explain it, rewrite it or draft a reply.

Private by design

No account, no tracking. Chats stay on your device; page text is never stored on our servers.

iPhone, iPad and Mac

A floating ✦ button on iPhone and iPad, a sidebar and a keyboard shortcut on Mac.

How it works

Install ContextFlow from the App Store and turn it on in Safari (Settings → Apps → Safari → Extensions on iPhone; Safari → Settings → Extensions on Mac).
Open any website and tap ✦ — or click the ContextFlow icon in the toolbar (Control-Shift-E on Mac).
Pick Summarize, Key takeaways, Explain or Translate, or ask your own question.

Questions

Do I need an account?

No. ContextFlow works right after you turn it on in Safari. Subscriptions are tied to your Apple Account and work on all your devices.

Which AI does ContextFlow use?

Answers are generated by the newest OpenAI models. With the Own key plan you can also use your own Claude (Anthropic) key. Page text is sent only when you ask something and is not used to train models.

Does it work on every website?

On regular websites, yes. Safari doesn't let extensions read some pages (the start page, App Store pages, PDFs in some cases) — you can still ask general questions there.
