Too much to read? Hear the gist first, then decide

Last updated: 2026-10-31

When there's more to read than time to read it, stop reading everything in full. On a Mac with Corvi, tap the Fn key on any e-mail, article, report, chat or video and hear the gist in 3–5 sentences, in your language. Then decide: read it properly, answer it, or move on. Double-tap Fn to ask about the detail you need.

Why reading piles up

Most knowledge work arrives as text: e-mail, chat, documents, tickets, articles, reports. A 2012 McKinsey report estimated that knowledge workers spend about 28% of their working week on e-mail alone (McKinsey Global Institute). Add documents, chat and the articles you meant to read, and the pile grows faster than anyone can work through it.

The usual answer, skimming, has a cost: you either miss the important line or you read everything twice. What helps is triage: knowing in a few seconds what a text says and whether it matters to you.

A better order: gist, decision, detail

  1. Gist: what is this, in a few sentences?
  2. Decision: does it need me? Read it fully, reply, save for later, or drop it.
  3. Detail: only for the texts that matter, go deep, with questions.

Reading everything in full puts step 3 first for every text, including the ones that didn't need you.

How to do it with Corvi

  1. Open the text: an e-mail, a web article, a Google Doc, a PDF, a Slack thread, a YouTube video.
  2. Tap Fn. You hear the gist in a few sentences. In e-mail and chat, what's asked of you and any deadline come first.
  3. Decide. If it matters, double-tap Fn and ask: "What are the numbers?", "What are the risks they mention?", "What do they want from me by Friday?"
  4. Reply by holding Fn and speaking.

Because you're listening, your eyes are free: you can lean back, stand up or keep a document open in another window while you take in the next one.

Stop typing. Stop reading. Talk and listen.

Corvi gives you the gist rather than every word. For texts you need in full, read them, or have macOS read them aloud word for word. See read aloud on a Mac.
