FAQ

Questions

What files can I import?

PDF, EPUB, Word, TXT, Markdown, and Kindle (MOBI, AZW3). PDFs keep their layout; other formats reflow to fit your screen.

Are my files private?

With your AI consent, new books are prepared in the cloud. Temporary originals are deleted when processing finishes, or within seven days if it cannot complete. Questions send relevant passages to the AI provider. Without consent, reading uses local parsing only. We never train models on your content.

How is it different from ChatGPT or NotebookLM?

They forget you between sessions. Resage remembers what you read and discussed, and grounds every answer in your actual file.

What about scanned PDFs?

With AI consent, scanned text is recognized during Digest. Recognized pages are flagged so you know when to double-check.

How much does it cost?

Free to start with a limited discussion allowance. Plus is $9.99/month or $99.99/year, and Pro is $29.99/month or $299.99/year with 3x the Plus allowances. Reading itself is not charged; read-through and scanned-page text recognition have monthly allowances.

Does it work on iPhone and iPad?

Yes. Your library syncs through your Resage account across Mac, iPhone and iPad.
