Audeus is an AI document assistant for students, researchers, professionals, and anyone who works with PDFs and digital documents. It supports conversational questions, summaries, key-point extraction, formula explanations, inline citations, highlighting, comments, drawing annotations, and text-to-speech playback. Beyond PDFs, it handles Word documents, non-DRM EPUBs, images, screenshots, web pages, and plain text. Its broadest appeal is to readers who want to combine document analysis with listening, especially across web, iOS, Android, and Chrome.

The free tier provides standard voices, limited access to Pro voices, limited document uploads, and a free text-to-speech extension. Pro is listed at $9.92 per month with annual billing and adds natural AI voices, PDF and Word support, OCR scanning, mobile and web access, a Chrome Extension, and Canva integration. Enterprise uses volume-based pricing and adds a dedicated support channel, tailored onboarding and training, and advanced user management. This structure makes Audeus approachable for individual readers, while larger teams have a defined path to administrative features.

Text-to-speech is the standout capability: playback speed can be adjusted, and voiceovers can be exported to Canva. OCR extends the workflow to scanned PDFs and images, while inline citations connect answers to source passages. Integrations with Canva, Google Docs, Gmail, and Outlook broaden its place in document workflows. Choose Audeus if multimedia reading, citations, OCR, and cross-device access matter most. It is less suitable for users who need generous free usage, prefer monthly Pro billing, or require enterprise controls without moving to a volume-priced plan.
