In 2007, business professor Sophie Leroy coined a term that explains almost every mid-afternoon burnout: Attention Residue.

The premise is straightforward: when you switch from Task A to Task B, your attention doesn't seamlessly follow you. A part of your brain remains stuck on the previous task, creating a mental drag that lowers your cognitive performance.

We usually blame context switching on meetings or Slack notifications.

In reality, the most frequent context switch happens during a seemingly harmless activity: trying to find something you previously saved.

The 20-minute rabbit hole of simple search

Picture this common scenario:

1. You’re writing an email, working on code, or drafting a plan.
2. You need that one statistic or quote you saw last Tuesday.
3. You switch over to your notes, browser bookmarks, or Twitter history to grab it.
4. The keyword search yields nothing.
5. You open another app, check your gallery, spot an unread notification, see an unrelated headline, and get distracted.

By the time you finally locate the snippet—or give up—it’s been 15 minutes.

Worse, your original train of thought is gone. You now need another 15 minutes just to get back into a flow state. What was meant to be a 5-second lookup effectively cost you half an hour of deep work.

The real goal of personal recall: Zero friction

Most note-taking apps and "second brains" make the mistake of requiring heavy maintenance. They force you into:

• Deciding where to file something.
• Navigating complex folder trees.
• Running multiple search filters just to find a single paragraph.

Every extra second spent managing information is mental energy stolen from actually using that information.

When we designed Klara, the driving rule was simple: retrieval must be instantaneous, or it isn’t worth using.

• You shouldn't have to leave your flow to search.
• You shouldn't have to recall the exact keywords or navigate nested tags.
• Whether you remember a single word or just describe the context vaguely, the answer should surface in seconds—on-device and private—so you can grab it and immediately return to what you were actually doing.

External memory shouldn't feel like a library you have to visit and browse. It should act like an instant reflex that keeps your focus where it belongs.

How often does a simple "let me just check that one note" turn into a 15-minute distraction for you?
