Billing FAQ
Good to know
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?+
More than 25 natural voices across two engines, in several accents. 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.
What does Premium include and what does it cost?+
Premium is $29 per month or $139 per year and includes 150,000 words of listening every month, all voices, speeds up to 5×, narrated diagrams and code, offline downloads and the AI study tools (summaries, quizzes, podcasts and the page assistant).
Can I cancel any time?+
Yes. Subscriptions are billed through the App Store or Google Play and can be cancelled from your store subscription settings. Access continues until the end of the paid period.
How do I delete my account and data?+
Open Profile → Delete account in the app, or follow the steps on our account deletion page. Your library, audio downloads and profile are removed permanently.
