Audeus

Audeus brings document listening, scanning and annotation into one app for students, researchers and executives who work through substantial reading workloads. It is a strong fit for people who want to hear and mark up source material across devices, rather than primarily query documents with AI.

Overview

Audeus converts PDFs, Word documents, non-DRM EPUBs, scans, screenshots and other text into speech. It advertises AI voices in more than 50 languages, with spoken-text highlighting and adjustable playback speed. That combination makes it more useful for sustained reading than a basic read-aloud tool, though a reader focused on asking questions of PDFs may find a document-analysis app a closer fit.

Key features

Listening and annotation

Text highlighting follows the spoken content, helping readers keep their place, while adjustable speed supports both careful listening and faster review. Pro allows speeds up to 3.5x, a meaningful benefit for readers who want to move quickly through familiar material. Highlights, notes and comments keep reactions alongside the document; shape highlights also let users mark images and graphs. This is a broader reading workflow than speech alone, but it is not a substitute for a tool centered on document question-and-answer.

Scanning and integrations

Audeus can scan printed pages and batch-scan multiple pages, bringing paper material into the same listening and markup workflow. Pro includes Canva integration, and the Chrome extension works with Google Docs and Gmail. These connections make the product more adaptable to mixed reading material, though users should weigh the limits on free document uploads before relying on it as a regular intake route.

Pricing

Free

The Free plan costs nothing. It includes standard free voices, limited access to Pro voices, listening on all devices, limited document uploads and a free text-to-speech extension. It is a sensible way to try the reading workflow, but limited uploads and restricted Pro voices make it less suited to sustained, high-volume use.

Pro

Pro costs $119.04 a year, billed annually at $119.04 per year ($9.92/month, billed annually). It adds natural, high-quality voices, PDF, Word and other file support, iOS, Android and web access, playback up to 3.5x, printed-text scanning, the Chrome Extension and Canva integration. This is the plan for frequent readers who need the expanded voice and scanning features; its annual billing is a commitment rather than a month-to-month option.

The Pro trial lasts 3 days at no cost. The selected plan starts automatically afterward unless canceled, so anyone testing Pro should cancel in the app settings before the trial ends if they do not want the plan to begin.

Enterprise

Enterprise has custom pricing based on volume for teams, companies and educational institutions. It includes a dedicated support channel, tailored onboarding and training, and advanced user management, making it the relevant option for organizations that need managed access rather than an individual plan.

Platforms

Audeus is available on web, iOS and Android, with a Chrome extension. Listening across devices makes it practical for readers moving between desktop and mobile, while the extension adds access alongside Google Docs and Gmail. Users should also consider that the privacy policy says uploaded text and documents may be collected as user content and that services are hosted in the United States. Audeus says it maintains administrative, technical and physical safeguards, but does not guarantee complete security or privacy.

Who it's for

Audeus suits students, researchers and executives who handle large reading workloads and want to listen, annotate and scan within one service. Multilingual readers may also value its advertised support for more than 50 languages. It is a less natural choice for someone whose main need is to interrogate PDFs, or for a reader whose document volume will quickly run into the Free plan's upload limits.

Pros and cons

• Pros: It combines speech, document markup and batch scanning, so readers can work with digital and printed material in one reading workflow.
• Pros: Support for PDFs, Word files, non-DRM EPUBs, scans and screenshots, plus more than 50 advertised languages, covers a wide range of reading inputs.
• Pros: Web, iOS, Android and Chrome extension access supports reading across devices, with Canva integration on Pro.
• Cons: The free plan limits document uploads and access to Pro voices, restricting its usefulness for regular high-volume reading.
• Cons: The three-day Pro trial automatically starts the selected plan unless canceled, leaving little time to evaluate the paid features.
• Cons: Uploaded material may be collected as user content, and the service does not guarantee complete security or privacy.

Alternatives

For document-focused work, AI PDF Assistants is a category to explore. Choose ChatPDF instead when PDF analysis is the priority: its free plan allows 2 documents per day, and ChatPDF Plus offers unlimited document analysis. Anara may suit readers who want connected research files, with Google Drive, Notion and OneDrive connectors in its Pro plan at $20 a year. AskYourPDF is another freemium option, with a Premium plan at $11.99 a year billed per month, billed yearly. DeinPDF offers a pay-as-you-go approach with a €0 monthly base fee, €0.50 free starting credit and top-ups from €10. ChatDOC, DeepPDF, docAnalyzer and Doxy are also alternatives to consider.

Verdict

Choose Audeus if you want one cross-device app for listening to, scanning and annotating substantial amounts of reading material. Its combination of input formats and markup is the clearest reason to choose it; the restricted free uploads and voices, annual Pro billing and automatic trial conversion are the main reasons to look elsewhere or stay on Free.
