Pick your hours.

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.

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.

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.

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.

Yes. Download a document for offline listening and every sentence is synthesised once and stored on your device. Replays never cost extra words.

Three monthly plans, sized in hours: Standard ($9.99, 6 hours), Pro ($24.99, 18 hours) and Ultra ($49.99, 12 hours plus 2.5 hours of Ultra studio voices). Every plan includes all natural voices, AI study tools, offline downloads and folders. Hours count only the first time a passage is spoken — replays and offline listening are free — and your remaining time is always shown in the app. Allowances reset on the 1st of each month.

Ultra voices are studio-recorded narrators that also return exact word timings, so the highlight is locked to the voice. They cost about ten times more to produce, so they have their own allowance on the Ultra plan. Every plan can preview all of them.

Yes. The full app runs in your browser at studyapp.cognitivesquad.com/app — nothing to install. Sign in with the same Google account you use on your phone and your library, reading positions, notes and remaining hours sync across every device.
