Once installed as a Chrome or Edge extension, or opened as an iPhone, iPad or Android app, it reads supported pages and documents aloud using natural AI voices while a word-synced highlight and auto-scroll keep your place. A public Voice Hub lets you preview real voice samples by language before committing, and playback speed ranges from standard rates up to 3x on the paid plan. What separates it from a plain screen reader is a feature called Read & Explain. Instead of only pronouncing a dense or foreign-language paragraph, CastReader works out what it means and walks you through it in the language you know best, while an animated pen circles and underlines the relevant lines in the original text. That mix of eyes-on-page and ears-on-explanation is aimed at research papers, technical documentation, foreign-language news and other long reads where passive narration is not enough. Sources are organised into four families: book platforms such as Kindle, WeRead, Google Play Books, Libby, Kobo and O'Reilly; articles and subscriptions including Medium, Substack, The Atlantic, The New Yorker and major newspapers; work documents and email such as Google Docs, Notion, Gmail and Google Drive; and AI conversations from ChatGPT, Claude, Gemini, DeepSeek and Kimi. CastReader also offers private voice cloning for your own documents and a developer Voice API for embedding cloned speech into applications. Free use needs no account, and payments are handled by Stripe. **Pricing & Plans:** Freemium. Free plan: $0 forever with 20 minutes of listening per day, standard voices up to 1.25x speed, 3 AI explains per day, and 30,000 translation characters per day when signed in.

The product turns anything text-based on the internet into audio. Highlight a passage on a page, right-click and choose "Listen with Liso", or paste text directly into the app — Liso converts it into natural-sounding speech in seconds. The result is less a traditional screen reader and more a personal podcast assembled from your own reading list. The workflow is designed around one-click capture. A Chrome extension handles anything on the web: long-form articles, newsletters, Substacks, blog posts and threads. For anything that is not in a browser — a document, an email, a note — you can paste the text into the app instead. From there, plays are organised with folders and tags so a growing queue does not turn into a mess of saved links. Listening is built for real life rather than the desktop. Multiple premium AI voices cover different material, playback speed adjusts from 0.75x to 2x, downloads let you listen offline on flights and commutes, and playback position resumes across devices so you can start on a laptop and continue on a phone. Liso uses a freemium model: a free tier covers a few listens a month, and paid plans unlock unlimited listening and longer-term access. **Pricing & Plans:** Freemium. The free tier includes a few listens per month. Paid tiers: Diamond $17/month (unlimited listens), Titanium $88 for 6 months, and Platinum $107 for 12 months (presented as best value). - **One-click capture from any page:** Highlight text on any website, right-click and select "Listen with Liso" to convert it to audio in a single step. Pasting text into the app works too. - **Multiple natural AI voices:** Choose between several premium AI voices so different types of content — news, essays, newsletters — sound right for the material. - **Adjustable playback speed:** Fine-tune reading pace from 0.75x to 2x to match the content type and how fast you can comfortably follow along. - **Offline downloads:** Download any listen for offline playback, so flights, tunnels and commutes never interrupt your queue. - **Cross-device resume and organisation:** Playback position syncs across devices, letting you start on a laptop and pick up on a phone or tablet exactly where you left off, with folders and tags to organise listens. **Strengths:** One-step capture from any web page via the Chrome extension, with text paste as a fallback; Offline downloads and cross-device resume make it practical for commutes and flights; Adjustable 0.75x–2x speed and multiple premium voices; Free tier lets you evaluate the voices before paying **Limitations:** Free plan limits you to a few listens per month; Full one-click convenience depends on installing the Chrome extension; The public site does not detail how many voices or languages are supported [Profile (Markdown)](https://openaitools.app/tool/liso.md) ## Frequently Asked Questions ### How do CastReader and Liso compare in monthly traffic?
