## CastReader

CastReader is built for people who want to consume long-form text with their ears as well as their eyes. 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. Pro: $4.99/month or $35.99/year (about $3/month, 40% saving) removing the daily listening cap, unlocking full ebooks and long PDFs, more premium voices up to 3x speed, unlimited daily explains, 120 personal-voice minutes per membership month, and 3,000,000 translation characters per month. A 3-day free trial is available; billing is via Stripe.

- **Synced read-aloud:** Natural AI voices narrate webpages, PDFs, ebooks and documents while each spoken word is highlighted and the page auto-scrolls, so you never lose your place.
- **Read & Explain:** Instead of only reading a hard passage, CastReader summarises and unpacks its meaning in the language you know best, with an animated pen marking the key lines in the original text.
- **Wide source coverage:** Works across Kindle, WeRead, Google Play Books, O'Reilly and other book platforms, news and newsletter sites, Google Docs, Notion, Gmail, plus ChatGPT, Claude, Gemini, DeepSeek and Kimi answers.
- **Voice Hub and voice cloning:** Preview real samples of dozens of voices across many languages, and create private cloned voices that Pro members can apply to their own PDF, EPUB, Word and TXT files.
- **Developer Voice API:** A REST API for text-to-speech and private voice cloning in 10 languages, returning MP3 or WAV, priced at $8 per 1M characters for successful generations.

**Strengths:** Combines plain read-aloud with guided explanations that point back at the source text; Covers an unusually broad set of sources, from Kindle and Gmail to ChatGPT and Claude answers; Free tier is genuinely usable with no account required, and the 3-day Pro trial needs no commitment; Personal voice cloning and a pay-per-success Voice API extend it beyond a simple reader

**Limitations:** The 20-minute daily listening cap on the free plan runs out quickly for long books or PDFs; Source support and iOS previews vary by platform, browser version and content access rules; Applying a cloned voice to your own text is limited to 120 minutes per membership month even on Pro

## Moises

Moises began as one of the best-known AI vocal removers and has grown into a complete creative suite for musicians. Its core stem separation engine isolates vocals, drums, bass, guitar, piano, keys, winds and strings, supporting up to 27 stem types with high-fidelity models. You can mute or solo any part, drop the tempo, transpose the key and loop tricky passages to practice them slowly.

Beyond practice, Moises adds composition and performance tools. A chord finder detects the harmony of a track, lyric transcription writes out the words, and a built-in metronome and speed changer help you stay in time. Moises Studio lets bands, producers and co-writers arrange, record and edit the same session together in the browser in real time, with no file handoffs. Video recording tools capture performances with studio-quality audio.

Moises runs as a web app in any browser and as native apps for iPhone, iPad, Android, macOS and Windows, so you can practise on the bus or produce at your desk. It is trusted by Grammy-winning artists, music schools and millions of hobbyists alike, and the company states it never trains on your personal audio.
