In their own words
Audeus
Audeus converts PDFs, documents, scans, screenshots, and other text into speech using AI voices. It supports PDF, Word (DOCX), and non-DRM EPUB files, and advertises more than 50 languages. As audio plays, spoken text is highlighted; playback speed can be adjusted, with Pro listing speeds up to 3.5x. Users can highlight documents, add notes and comments, and mark images or graphs with shape highlights. The app can scan printed material, including multiple pages in a batch. Listed platforms are Android, iOS, web, and an extension; the Chrome extension page says it works with Google Docs and Gmail, while Canva integration appears on the pricing page. Free includes standard voices, limited access to Pro voices, and limited document uploads. Pro is listed at $119.04 per year, billed annually ($9.92/month), and includes a three-day trial. The selected plan begins automatically after the trial unless canceled. The company offers volume-based pricing for teams and institutions.
PDF.chat
PDF.chat lets users upload documents, ask questions, and receive answers cited to exact pages in over 100 languages. It accepts PDFs, Word and PowerPoint files, text files, and images, including scanned or photographed documents that its OCR models read on its own infrastructure. Long documents are indexed so questions can retrieve relevant pages from reports, textbooks, and dockets. Users can compare Claude, GPT, Gemini, Llama, and DeepSeek answers side by side in one chat, then export results as plain text, Markdown, DOCX, searchable PDF, CSV, or JSON. The service runs in a browser without a download or installation. Its REST API ingests documents, returns per-page text and metadata, and supports chat with page citations; API use is metered per page. The Free plan costs nothing, with pages resetting at midnight UTC and no credit card required. Starter costs $5 a month and includes 750 pages per month. PDF.chat says files are automatically deleted shortly after processing and are not sold, shared, or used for training; on paid tiers, relevant passages may be sent to third-party AI providers.
