Hear one paragraph.
Then choose who reads
the other 94,000 words.

Timbra turns the documents you never find time to read — two-column papers, scanned books, textbooks full of tables — into audio you'll actually finish: properly chaptered, with a reading page that follows every word. Hear your first paragraph free, then see the measured quality before you pay a cent.

Call me Ishmael. Some years ago never mind how long precisely having little or no money in my purse, and nothing particular to interest me on shore, I thought I would sail about a little and see the watery part of the world.

What you can put in

Most readers give up on the hard half of your shelf.

Timbra routes each document to the parser that handles it best, then tells you what it found before it starts reading.

Two-column papersReading order fixed, equations spoken or skipped, citations muted, reference list left out.
Scanned booksOCR with a per-page confidence score. Pages we're unsure about are flagged, not guessed.
TextbooksTables narrated row-wise or summarised. Figure captions read on request.
EPUB & DOCXChapters lifted straight from the spine or the outline, then shown to you to edit.
Articles & preprintsPaste a URL or an arXiv ID. Arrives in your library by the time you've made coffee.
Public domainThousands of titles already narrated and free to listen to, in every voice we ship.
Who it's for

Five people, one problem: the reading won't fit in the day.

Researchers

The reading list that never shrinks

Drop in a week of preprints. Get them chaptered by section, with the maths spoken properly and the bibliography left where it belongs. Ask the document a question and it answers with the page number.

Night readers

For the hour before sleep

Wind-down slows the narration, brings up the rain and fades out on a timer. When you wake up, it resumes thirty seconds before you stopped paying attention.

Sleep timer with rollback · screen never whites out

Teams & institutions

One licence, a whole reading list

Shared shelves, seat management, and a per-document audit of what was read aloud and what was skipped. Data stays in the EU.

EU regions only · DPA + sub-processor list

Voice Studio

Audition voices on your paragraph, not a demo script.

We pull two passages out of your document — one plain narrative, one thick with names and numbers — because that second one is where cheap narration falls apart. Everything you change updates the price as you go.

The harbour kept its own hours. Long after the town had folded itself away for the night, the cranes went on turning, and the light on the far mole answered them once every four seconds, patient as a metronome.

Chapter 7 · Statistical Foundationsp. 142
Estimation begins with a confession: we do not know the parameter. What we have instead is a sample, and a willingness to be wrong in a way we can quantify. Everything that follows — the intervals, the tests, the long apologetic paragraphs about assumptions — is bookkeeping on that single admission.
Reading mode

The page stays lit while the room stays dark.

Follow along word by word, or turn the text off entirely and just listen. Your place syncs across every device, down to the sentence.

  • TAPTap any word to jump there. Alignment is accurate to under 100 milliseconds, so the audio lands where your eye is.
  • VIEWTwo views. Reflow for comfort, or the original page image with the current sentence lit — the one academics ask for.
  • HOLDHold to leave a voice note. It attaches to the timestamp and exports with your highlights.
  • CARCar, walk and sleep modes. Big targets, no reading required, and a sleep timer that rewinds to where you actually drifted off.
The Quality Card

Nobody else will tell you how good the audio actually is.

Every chapter is transcribed back and compared to the source, scored for naturalness, and checked for voice drift. You see the numbers, what pulled them down, and exactly what it would cost to fix.

Ambience & Seasons

A room to read in, not just a file to play.

A soundbed sits under the narration at a level you set, and ducks itself when the voice comes in. Every thirty days the Season changes — a new set of beds, a new palette, a new nightly piece.

Season 03 · Long Nights · day 12 of 30

Tonight: Rain on the mole

Generated fresh at your local dusk, seeded from the date so everyone on Season 03 hears the same twelve minutes tonight. Tomorrow it's gone.

Hearth — low strings, room tone, a fire that never quite settles. Chosen for you: it's 23:10, it's raining outside, and you've been on the same chapter for three nights.

Season 03 · your nights

Nine of twelve. Finish the Season and it stays in your library — the only way to keep a night once it's passed.

The beds are generated, not licensed. Procedural pads and field textures, composed on your device from a daily seed. No royalties, no repetition, no track that a rights-holder can pull out from under you.

Reading together

A community with no feed and no follower count.

You can tell people what you're reading and let them hold you to it. You cannot scroll here, and nobody can see how many people are watching you.

Listening room

Long Nights, open now

Nine people are reading with the same soundbed right now. No names, no chat, no leaderboard — just the knowledge that the room isn't empty. Turn it off and it never comes back.

Circles

Up to twelve people, one shelf

Pick a book, set chapter checkpoints, and leave thirty-second voice notes in the margin for each other. Everyone hears them at the exact moment they reach that paragraph.

Share cards carry your progress and your own words — never the audio, never the book's text. What you upload stays yours and stays private.

Pricing

Pay for the book, or pay for the month.

Per-document prices are calculated from the actual work your file needs — pages, scan quality, language, voice — and then fixed. Subscriptions come with an allowance in hours, so you always know where you stand.
