How to find something you saw on your Mac

You know you saw it. It was right there on your screen — a booking reference, the name of a restaurant, the exact wording of an error. Now you need it, and it isn’t where you thought.

Before you install anything, try these, roughly in the order that works most often.

1. Go back to where it came from

Most things we see on a Mac come from a handful of places, and each one has its own search.

• Mail: the search field matches the text of messages, not just subjects. Try a distinctive word rather than a whole phrase.
• Messages: the search field at the top of the sidebar searches every conversation, including links and attachments.
• Notes, Reminders, Calendar: each has its own search field; Calendar searches event titles and notes.
• Slack, Teams, Discord: their search usually beats anything else for what was said there.

2. Search your browser history

If you saw it on a web page, your browser remembers the page — though not what was on it.

• Safari: History › Show All History, or ⌘Y. Type a word from the page’s title or address.
• Chrome, Edge, Brave, Arc: ⌘Y opens History, with a search field.
• Just closed it? Safari keeps History › Recently Closed; in Chrome-based browsers, ⇧⌘T reopens the last closed tab.

History searches titles and addresses, not the text of the page. If you remember a sentence but not the site, this is where it gets hard.

3. Search your whole Mac with Spotlight

Press ⌘Space and type. Spotlight searches file names and the text inside documents, PDFs, presentations and emails. A few tips:

• Put an exact phrase in quotation marks.
• Add kind:pdf, kind:image or kind:presentation to narrow results.
• Choose “Search in Finder” at the bottom of the results for more filters (date, folder, kind).

macOS can also recognise text in images in the background and add it to Spotlight’s index. It can take a long time after an image is created, and independent testing found results inconsistent, so treat it as a bonus rather than something to rely on.

4. Read the text in a picture you already have

If you took a screenshot or saved an image, macOS can read it for you. Open it in Preview or Photos, move the pointer over the text and select it as you would in a document — then copy it, look it up or translate it. Apple calls this Live Text. It works in Safari too, on images in web pages.

5. Check the clipboard and the app’s own history

• If you copied it, it might still be on the clipboard: paste it somewhere.
• Many apps keep their own history: a terminal’s scrollback (⌘F in Terminal), a document’s version history (File › Revert To › Browse All Versions in Apple’s apps), an app’s “recent” list.

6. Ask the source again

Sometimes the fastest way is the human one: the delivery company can resend a tracking number, the shop can resend an order confirmation, a colleague can paste the link again. No shame in it.

7. Next time: let your Mac remember for you

Everything above works only if the thing was saved somewhere. Much of what we see never is: a page we read without bookmarking, a code shown for a minute, a message in an app with poor search, a dialog that closed.

That is what a screen memory is for. It keeps a light, compressed memory of what was on your screen and reads its text, so you can type a word and land on the moment you saw it.

DejaVu is one, built natively for Mac. It reads text on your Mac with Apple’s own frameworks, and never sends your memories anywhere: no account, no cloud, no audio, no keystrokes. Your memory is encrypted and opens with Touch ID. It can’t bring back what you saw before you installed it — but from then on, “I saw it somewhere” becomes a three-second search.
