Running headers, footers and page numbers are dropped so a chapter flows like one continuous piece. You can upload a PDF of up to 100 MB and 1,000 pages, paste an article link, or upload a saved HTML page, and everything lands in a single library. Audio plays in the browser on phone or desktop, and the web app can be added to a phone home screen so it behaves much like a native app. Two American English voices, one female and one male, are available, and the interface and narration are English-only for now. The first 40,000 words are free on your own documents, roughly four papers or twelve articles, with no card required. After that a subscription costs $99 per year (about $8.25 a month) or $11 per month, cancellable in one tap. Descriptions and table summaries the platform adds do not count against your word allowance, and word counts are shown before you convert. **Pricing & Plans:** Free tier covering the first 40,000 words with no card required. Paid subscriptions: $99 per year or $11 per month. Refunds available within 14 days of a first payment, minus words already converted; unused purchased words are refundable at any time. - **Figures described in words:** Charts and diagrams are narrated as what they show rather than skipped or read as a bare figure number. - **Tables summarised:** Instead of fifty cells read one by one, you hear the conclusion the table supports. - **Page clutter removed:** Running headers, footers and page numbers are left out, and headings get a pause so chapters sound continuous. - **PDFs and articles in one library:** Upload PDFs up to 100 MB and 1,000 pages, paste article links or add saved HTML pages, all stored together. - **Transparent word accounting:** Every document shows its word count before conversion and the app displays how many free words remain. **Strengths:** Handles figures, tables and code that typically break read-aloud tools; Generous 40,000-word free allowance with no card required; Clear pricing and a documented 14-day refund policy; Works in the browser and can be installed to a phone home screen **Limitations:** English-only narration and interface for now; Just two American English voices; No native iOS or Android app yet [Profile (Markdown)](https://openaitools.app/tool/article2audio.md) ## Readio Readio is an AI text-to-speech reader designed around a simple observation: a lot of reading does not require your eyes. Reports, course readings, ebooks, and long articles can be absorbed while commuting, exercising, or doing chores, if the audio is clear enough and you can still track where you are. Readio's core feature set is built to make that practical rather than fiddly. The reader works in two modes. A text reader handles webpages and pasted text, while a file reader accepts PDF, EPUB, DOCX, RTF, ODT, HTML, TXT, and Markdown uploads, so you generally do not need to convert anything first. During playback, sentences highlight in sync with the audio and the page scrolls automatically, which is the difference between listening and actually following along. Playback controls let you change speed, jump between sections, and move to specific parts of a long document. On the voice side, Readio uses OpenAI's text-to-speech engine and exposes six voices with distinct characters, from the balanced Alloy to the narrative Fable and the bright Nova. It advertises reading support across more than 140 languages and dialects. There is also a practical filtering layer that skips footnotes, superscripts, and bracketed asides so the audio stays clean, with the option to manually exclude sections. Readio runs on a freemium model with a free tier and paid plans. **Pricing & Plans:** Freemium. A free tier lets you start listening at no cost, and paid plans remove usage limits and unlock the full feature set. Exact caps vary, so check the pricing page for current terms. - **Live highlight and auto-scroll:** As the document is read, sentences highlight in sync with the audio and the page scrolls automatically, so you never lose your place. - **Natural neural voices:** Six OpenAI TTS voices, including Alloy, Echo, Fable, Onyx, Nova, and Shimmer, cover neutral, narrative, and expressive styles for different content types. - **140+ languages and accents:** Read in over 140 languages and dialects, with regional English, German, French, Spanish, and Chinese variants available. - **Smart content filtering:** Built-in filters skip footnotes, superscripts, and bracketed text, and you can manually exclude sections you do not want spoken. - **Broad document format support:** Upload and listen to PDF, EPUB, DOCX, RTF, ODT, HTML, TXT, and Markdown files without converting them first. **Strengths:** Handles a genuinely wide set of document formats without conversion; Synced highlighting makes long-form listening much easier to follow; 140+ language and dialect coverage with regional accent variants; Practical content filtering for footnotes and asides **Limitations:** Free tier has usage limits; heavy listening pushes you to a paid plan; Voice selection is tied to the underlying OpenAI TTS voice set, so you get six voices rather than a large library; Very large files may hit upload size limits on lower tiers [Profile (Markdown)](https://openaitools.app/tool/readio-1.md) ## Frequently Asked Questions ### How do article2audio and Readio compare in monthly traffic? article2audio has 2,280 monthly visits, while Readio has 12,402.
