Audeus

Audeus is a text-to-speech reader with scanning and annotation tools for people handling substantial reading workloads. It is best suited to students, researchers, and executives who want to listen to and mark up material across devices. Its breadth is compelling, but the free tier is restricted and the Pro trial renews automatically unless canceled.

Overview

Audeus turns 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. The combination of listening and markup is useful for working through source material, though readers whose main need is asking questions about PDFs may be better served by a document-analysis app.

Key features

Listening and annotation

Text highlighting follows the spoken content, while adjustable speed lets readers choose a deliberate pace or move faster through familiar passages. Pro supports speeds up to 3.5x, a useful ceiling for readers prioritizing throughput, but one reserved for paid subscribers. Highlights, notes, and comments keep reactions alongside documents; shape highlights also let users mark images and graphs.

Scanning and integrations

Audeus can scan printed material and batch multiple pages, bringing paper into the same listening and annotation workflow. Pro includes Canva integration, and the Chrome extension works with Google Docs and Gmail. These additions broaden the ways users can bring material into Audeus, but do not make it a substitute for tools built chiefly around document questions and analysis.

Pricing

The Free plan costs nothing. It includes standard free voices, limited access to Pro voices, listening on all devices, limited document uploads, and the free text-to-speech extension. It is a sensible way to see whether Audeus's reading workflow suits you, but limited voices and uploads constrain regular heavy use.

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 and Word support and more, iOS, Android, and web access, speeds up to 3.5x, printed-text scanning, Chrome Extension, and Canva integration. This is the fitting plan for frequent readers who need the higher speed ceiling and broader reading workflow; the annual billing makes it a commitment rather than a month-to-month option.

The Pro trial lasts 3 days at no cost. After the trial, the selected plan begins automatically unless canceled, so anyone testing Pro should cancel in the app settings before renewal if they do not want to continue. Enterprise uses volume-based custom pricing for teams, companies, and educational institutions, with a dedicated support channel, tailored onboarding and training, and advanced user management.

Platforms

Audeus is available on Android, iOS, web, and as a browser extension. That range suits readers who move between mobile devices and a computer; Pro explicitly includes iOS, Android, and web, while the free plan includes the text-to-speech extension.

Uploaded text and documents may be collected as user content, and Audeus hosts its services in the United States. The company says it maintains administrative, technical, and physical safeguards, but does not guarantee complete security or privacy. Readers handling sensitive material should weigh that carefully.

Who it's for

Audeus is a strong fit for students, researchers, and executives who process substantial reading and value listening, scanning, and annotation in one workflow. It is less suited to someone who mainly wants to interrogate PDFs with questions, or to a reader who needs generous free uploads and Pro voices without paying.

Pros and cons

Pros

• Supports PDFs, Word files, non-DRM EPUBs, scans, screenshots, and other text, giving readers several ways to bring material into one listening workflow.
• Spoken-text highlighting, notes, comments, and shape markup keep reading and annotation together, including on images and graphs.
• Batch scanning and access across Android, iOS, web, and extension platforms help accommodate paper and digital reading across devices.
• Pro combines high-quality voices, speeds up to 3.5x, scanning, and Canva integration for frequent readers.

Cons

• The free plan limits Pro voices and document uploads, which narrows its usefulness for sustained reading workloads.
• The 3-day Pro trial converts to the selected plan automatically unless canceled, leaving little time to evaluate before renewal.
• Pro is billed annually, so readers seeking a recurring monthly payment option may prefer another fit.
• Uploaded documents may be collected as user content, and complete privacy or security is not guaranteed.

Alternatives

For readers whose priority is asking questions about documents rather than listening and marking them up, ChatPDF offers a free plan with two documents per day and a ChatPDF Plus plan with unlimited document analysis and advanced features. Anara is another choice for users who want research-oriented connectors: its Pro plan costs $20 a year and includes Google Drive, Notion, and OneDrive connectors, along with 4x more AI usage than Plus and uploads up to 300MB or 10,000 pages. AskYourPDF may suit readers who need defined document and question quotas: its Premium plan costs $11.99 a year, billed yearly, and includes up to 2,500 pages per document, a 31MB maximum upload, 50 documents per day, and 1,200 questions per day.

DeinPDF uses a pay-as-you-go model with a €0 monthly base fee, €0.50 free starting credit, top-ups from €10, and usage-based charges. docAnalyzer offers a Community plan with document analysis, chat, notes, and monthly credits, subject to monthly upload limits and without API access.

Verdict

Audeus is a good choice for people who need to listen to substantial volumes of material and keep scans, highlights, notes, and comments in the same workflow. Its broad file support and cross-device access make it more versatile than a basic read-aloud tool. Look elsewhere if your main task is querying PDFs, if you need generous free uploads, or if an automatic trial renewal and annual Pro billing do not suit you.
