Why Study App
Built for the books that other apps skip
Most read-aloud apps stumble on technical material. Study App understands page structure, reads code deliberately and describes what's in the pictures.
Import anything
PDFs, articles and notes
Upload a PDF, paste a link or drop in text. Technical books with code, tables and figures are parsed on your device with headers, footers and citations skipped automatically.
Natural voices, word by word
Indian-first voices with live highlighting
Studio-quality AI voices read every sentence while each word lights up as it is spoken. Tap any sentence to jump there. Switch voices whenever you like.
Diagrams & code, narrated
Vision AI describes what text can't
Flowcharts, architecture diagrams, charts and code blocks are described and read in place, so technical books finally make sense while you walk, drive or cook.
0.5× to 5× speed
Fine control and auto-ramp
Adjust playback in small steps, skip 10 seconds either way, set a sleep timer, and let the auto-ramp nudge the speed up as you get comfortable.
Offline & background
Download once, listen anywhere
Download whole documents for offline listening. Playback continues in the background with lock-screen controls, and never pauses your music unless you want it to.
AI study tools
Summaries, quizzes, podcasts, assistant
Summarise a page, chapter or the whole book. Quiz yourself with explained answers. Turn a chapter into a two-host podcast. Ask the assistant anything about what you are reading.
How it works
Three steps from PDF to podcast
Add a document
Upload a PDF, paste a link or type text. Parsing happens on your phone in seconds, even for 700-page books.
Press play
Choose a voice and speed. Headers, footers and citations are skipped; figures and code are narrated in place.
Study smarter
Bookmark, highlight, search, download for offline, then summarise, quiz or podcast the chapter you just heard.
A closer look
Designed for long, focused listening
A home that keeps your place
Pick up where you left off, add a PDF, a link or text in one tap, and see what you added recently.

Reflowed text with live highlighting
Clean, readable text with every word lit as it's spoken. Tap any sentence to jump. Switch to the original page any time.

A player built for long reads
Skip 10 seconds, change voice or speed mid-sentence, set a sleep timer, and keep listening in the background.

Study tools on every page
Summarise, explain simply, quiz yourself, generate a two-host podcast or ask the assistant about the page you're on.

FAQ
Questions, answered
What can I listen to?+
PDFs (including scanned-looking technical books with code, tables and diagrams), web articles via a link, and any text you paste or type. Every import is parsed on your device, cleaned of headers, footers and page numbers, and read aloud sentence by sentence.
How does it handle diagrams, flowcharts and code?+
Study App detects figures and code blocks while parsing. Figures are described by a vision model in plain language and narrated in place; code is read with a clear, deliberate style so you can follow along. You can turn this on or off in Listening settings.
Which voices are available?+
Nearly 30 natural voices, most of them Indian English — eight natural Indian personas plus ten studio-quality Indian narrators — alongside British, American and Australian options. Switch voices at any point and the current sentence is re-synthesised instantly.
How fast can it read?+
Anywhere from 0.5× to 5×, in fine steps. An optional auto-ramp slowly increases the speed as you listen so you can build up comfortably.
Does it work offline?+
Yes. Download a document for offline listening and every sentence is synthesised once and stored on your device. Replays never cost extra words.
