Reading · Alice's Adventures in Wonderland · Chapter 1
ENAlice was beginning to get very tired of sitting by her sister on the bank, and of having nothing to do: once or twice she had peeped into the book her sister was reading, but it had no pictures or conversations in it, “and what is the use of a book,” thought Alice “without pictures or conversations?” So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid), whether the pleasure of making a daisy-chain would be worth the trouble of getting up and picking the daisies, when suddenly a White Rabbit with pink eyes ran close by her.

How it works
Lecturia reads the ebooks you already own.
Lecturia is an audiobook generator. You give it an EPUB, PDF, TXT, FB2 or DOCX file, pick one of the e-reader voices, and it hands back a narrated audiobook you can play in the web app, on iOS and Android, and in the car on CarPlay and Android Auto. 7 languages, no studio, nothing to record.
Pick your e-reader
An e-reader is a named voice persona. Pick one, see the exact credit cost for your book on that voice, then convert. Nothing is charged until you confirm.
6 e-readers · 4 voice models · 7 content languagesListen anywhere
Web, iOS, Android, CarPlay, Android Auto. The sentence you're hearing is highlighted in the text. Your position syncs across every device, so the car picks up exactly where the kitchen left off.

In the app
Highlighted text, a position that follows you, controls made for the car.
Karaoke sentence highlighting
The sentence playing right now is highlighted in the text. Tap any other sentence to jump audio there. Per-chunk alignment runs server-side; if it ever fails for a passage, audio still plays.
Cross-device position sync
Sentence-anchored: not "page 47" but "the sentence about Hari Seldon's prediction". Close on the laptop, open on the phone in the car, resume exactly there.
CarPlay & Android Auto
Lock-screen controls, chapter navigation, playback speed from 0.5×-3×, and a sleep timer. Built for commutes as a first-class surface, not an afterthought.
Convert what you want to hear
Try a chapter before you commit to the book.
Conversion is per chapter and starts only when you say so. Listen to one, then decide whether the rest is worth your credits.
Convert by chapter
Open the table of contents and convert one chapter, the next 3, or everything that is left. Nothing converts until you ask.
Cost shown before you convert
Every chapter row shows its exact credit cost for the voice you picked. Switch the voice in the preview and the figures update before you spend anything.
Text and chapters, free
Extraction, cleanup and chapter splitting run on upload and cost nothing. Read the cleaned text and browse the contents before a single credit leaves your balance.
A chapter is ready in 30-90 seconds
Convert one chapter and it plays about 30-90 seconds later. Nothing about the rest of the book has to finish first.
Stop anytime, credits stay
Unspent credits never expire. A book you set aside after two chapters costs you two chapters.
Pricing
You pay for the books you convert.
Buy credits when you want audio. Each conversion shows its cost before you confirm it. There is no plan and nothing is charged monthly.

Developers
Turn any ebook into audio and structured text, from your own code.
Where to start
The same pipeline the app runs on is a REST API with a bearer key. Build it into a reading app, a course platform or a publishing workflow; Lecturia does the extraction, the voices and the audio.
Base URLhttps://api.lecturia.ai/v1/saas
Ebook in, clean text out
Upload EPUB, PDF, TXT, FB2 or DOCX. Get back cleaned text split into chapters and sentences, a table of contents, and a structured document of the book you can render yourself.
A book, a chapter or the next batch to audio
Convert everything, one chapter, or the next few in any e-reader voice. The exact credit cost is quoted before you commit, and each part comes back as MP3 with sentence-level timing.
Plain text to speech
Send text straight to a voice: short passages come back in the same request, long ones run as a job you poll or get notified about.
The voice catalog
List every e-reader with the languages it narrates and what a given book would cost on it.
Webhooks instead of polling
Register an endpoint and get a signed call when extraction or conversion finishes.
A sandbox that costs nothing
Test keys run the whole API without spending credits. Going live is a key swap, not a code change.
FAQ
The questions people actually ask.
What is Lecturia?
Lecturia is an AI audiobook generator. You upload an ebook, pick a named e-reader voice, and Lecturia turns the text into a natural-sounding audiobook you can listen to on Web, iOS and Android, CarPlay or Android Auto. It's built for people who already own ebooks they want to listen to, not buy again.
Which file formats does Lecturia support?
EPUB, PDF, TXT, FB2, DOCX up to 100 MB per file. Kindle KFX and AZW3 are not supported, because they're DRM-protected. Convert them to EPUB with Calibre first, then upload. See How it works
Whose voices does Lecturia use?
6 named e-readers at launch, powered by Google and OpenAI. Each one is a persona with a fixed voice and a stated set of languages, and you pick the one that narrates your book. Custom voice cloning is not in scope for v1. See E-readers
How is Lecturia different from subscription apps?
Subscription apps usually bill you every month or year, often after a free trial that turns into a charge. Lecturia charges per book or per credit pack, never per month, and credits you have bought do not expire. There's no trial, no auto-renewal, no retention loop. "Cancelling" means not buying more credits. See Pricing
Which languages does Lecturia support?
7 content languages for audio conversion: English, Spanish, French, German, Italian, Russian and Ukrainian. The app interface itself ships in 6 locales: English, Spanish, German, Italian, Ukrainian and Russian. Each e-reader lists the languages it narrates, and the catalog filters itself to your book's detected language.
How much does it cost?
There is no subscription. You pay in credits, and every conversion shows its exact credit cost before you confirm. Foundation by Isaac Asimov (about 420K characters) costs 908 cr on Google WaveNet or 2,326 cr on OpenAI GPT-4o mini TTS. Credits come in packs from €1.49 to €89.99, which works out to €0.0090-€0.0099 per credit depending on pack size. See Pricing
What do I get for free?
Lecturia is in an invite-only beta, and the starter grant is paused for as long as it lasts: an invited account is not credited automatically. Free either way, once you are in: uploading a book, reading the extracted text, and seeing the exact credit cost of every voice before you convert anything. Sampling the e-readers on this page costs nothing and needs no account. The starter grant returns when public sign-up opens.
Does Lecturia work in the car?
Yes. iOS integrates with CarPlay; Android integrates with Android Auto. You get lock-screen controls, chapter navigation, playback speed from 0.5×-3×, a sleep timer, and audio that resumes exactly where you left it on another device.
Where are my books stored?
On EU-jurisdiction infrastructure: uploaded files, extracted text and generated audio are stored in EU-jurisdiction storage. Some of our processors are US companies; those relationships are covered by GDPR safeguards (standard contractual clauses) - see our Privacy Policy. Your files stay yours: you can delete a book and its audio at any time.
