§ 01 — capabilities

A reading voice that thinks
about the page in front of it.

01 /

Read with your ears.

Long PDFs. Weekly newsletters. That essay you keep saving for later. HearFlow reads them at the pace you choose, while you do something else — and you finally get to the bottom of the pile.

02 /

From anywhere your eyes land.

Highlight in any app — Safari, Mail, Slack, Notion, a PDF preview — hit one keyboard shortcut, and the voice picks it up. No copy-paste, no upload, no opening a separate window.

03 /

Names said right.

Researchers, products, places, people — HearFlow says the names a generic voice would mangle the way a person would say them. The ones it doesn't know yet, it learns.

04 /

A voice that suits the page.

Long-form prose gets audiobook calm. A research paper gets measured beats. A Slack thread gets crisp. The same voice, in the right tempo for what you're hearing.

I built it for my sister — who's studying IB and reads more than her eyes can take. Then I realized I needed it too.

§ 02 — moments

Reading meets the rest
of your day.

01 — kitchen

While you cook.

Recipe on the counter, the long essay you saved last week in your ears. Both move at your pace. AirPods stay in, hands stay free.

02 — sidewalk

While you walk.

That paper you've been meaning to read travels with you. So does the morning Substack and the report you haven't opened. A commute that gives you something back.

03 — desk

While you focus.

Listen with one part of your mind while the other drafts, designs, or codes. Catch the brief out loud while your hands stay on the work.

04 — chair

While you rest.

Eyes off the screen for an hour. Still in the book, the article, the chapter you started last night. A quieter way to keep reading.

One shortcut. Anywhere on your Mac.

Select text. Tap Option+Space. The voice picks up on the first sentence. Tap again to pause; double-tap to stop. That's the whole interface — nothing to learn, nothing to launch.

  • ⌥ ␣Read your selection. Out loud, instantly.
  • ⌥ ␣Pause or resume. Tap once.
  • ⌥ ␣ ␣Stop. Double-tap to clear what's queued.
  • ⌥ →Skip ahead a beat. (Or back with ⌥ ←.)

One voice.
Every page.

HearFlow is one simple subscription — not a metered service. Listen for an hour or for ten. Read a single email or a whole textbook. The price stays the same, however much you use it.
