What Listen gives you

  • Any summary, out loud

    Summaries of YouTube videos, web articles and PDFs can all be read aloud.

  • Five speeds

    0.75x, 1x, 1.25x, 1.5x or 2x. Slow down for dense material, speed up for a recap.

  • In the language you chose

    Summaries can be written in more than 60 languages, so you can listen in yours.

  • Reading time becomes any time

    A three-minute summary fits into a walk to the station.

A summary you do not have to look at

Reading needs your eyes and a free hand. A lot of the day offers neither: walking, driving, washing up, the gym. Listen turns those stretches into time for the things you saved to read later.

Press Listen on any summary and SumAI reads it aloud at the speed you pick.

Choosing a speed

Speed Good for
0.75x Dense or technical material, or listening in a second language
1x Following along comfortably
1.25x Everyday listening once you are used to it
1.5x Recaps of things you partly know
2x A quick refresher

There is no right answer. Start at 1x and move up until you notice yourself missing things, then step back one.

Ways people use it

The commute queue. Share a handful of articles and videos to SumAI in the morning, then listen to the summaries on the way to work.

Review by ear. The night before an exam or a meeting, listen again to the summaries you read earlier in the week. Hearing material in a different form is a useful second pass.

Second-language practice. Set the summary language to the one you are learning and the speed to 0.75x. You get short, structured listening practice on topics you chose. See summaries in 60+ languages.

Resting your eyes. After a day of screens, listening is easier than reading.

What Listen reads

Listen reads the summary, not the original video or document. That is the point: an hour-long talk becomes a few minutes of audio containing its key ideas.

If a point catches your attention, the full source is still there. For videos, the key moments take you to the exact part of the original.

FAQ

Questions about listen

Can SumAI read a summary aloud?

Yes. SumAI's Listen feature reads a summary aloud, and you can set the speed to 0.75x, 1x, 1.25x, 1.5x or 2x.

Can I listen to a PDF or web article with SumAI?

You can listen to the summary of a PDF or web article. SumAI summarizes the document first, then the Listen feature reads that summary aloud.

What playback speeds are available?

Five: 0.75x, 1x, 1.25x, 1.5x and 2x.

Is listening to a summary better than watching the video at 2x?

They suit different goals. Watching at 2x still takes half the video's length and keeps the speaker's examples and tone. Listening to a summary takes a few minutes and gives you the key points. Use the summary to decide which videos deserve the fuller treatment.
