## 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

## JanitorAI

JanitorAI has evolved from an early bring-your-own-key chatbot directory into one of the largest independent roleplay ecosystems on the web. Rather than locking users into a single rigid model, the platform runs its own proprietary model family—JanitorLLM (JLLM), including the conversational JLLM-short variant that trims reply length by roughly 70%—for free to registered users. At the same time, power users can connect external API keys, reverse proxies, OpenRouter endpoints, or local LLM backends, complete with a redesigned proxy manager that supports drag-and-drop config reordering and reasoning 'thinking box' tags.

In mid-2026, JanitorAI introduced its first first-party monetization layer without restricting its free baseline: Janitor+ ($12.99/month) and the web-based Janitor+ Router. While standard users keep unlimited free messaging with around 9,000 tokens of context, Janitor+ subscribers gain 5x expanded context memory, priority queue placement during peak hours, and 300 enhanced monthly regeneration swipes powered by frontier models. Through the Janitor+ Router, subscribers can also fund an integrated per-token wallet to switch between third-party commercial LLMs directly inside JanitorAI with transparent per-token pricing and a 10% subscriber discount—eliminating the need to configure external proxy URLs.

For bot creators, JanitorAI offers deep technical customization rarely seen on mobile-first companion apps. Character definitions support payloads up to 1 MB, multiple initial greeting messages, and a dedicated Scripts engine that injects conditional logic and whole-word triggers so bots react deterministically to story state changes rather than relying on prompt compliance alone. Combined with granular generation rules—such as forbidden word lists, custom Top-K/Top-P sliders, repetition penalties, response prefill, and custom profile CSS—JanitorAI caters heavily to long-form writers and technical roleplayers.

**Pricing & Plans:** Core access to JanitorLLM (with ~9K token context and unlimited chats) and bring-your-own-key (BYOK) proxies remains completely free. The optional Janitor+ subscription launched in June 2026 at $12.99/month, adding 5x context memory, unlimited priority messages, 300 monthly frontier-model enhanced swipes, and access to the per-token Janitor+ Router wallet (with a 10% discount on popular third-party models).

- **Free JanitorLLM & JLLM-Short Engine:** Provides unlimited free character chats powered by JanitorAI's in-house LLM (~9K context window on free accounts), with a toggleable JLLM-short mode for snappy, dialogue-focused replies that are 70% shorter.
- **Janitor+ Router & Multi-Proxy Manager:** Lets Janitor+ subscribers tap directly into third-party frontier models via a built-in per-token wallet at a 10% discount, while keeping full BYOK reverse-proxy support with config duplication and reasoning tag display.
- **Conditional Character Scripts & 1MB Definitions:** Allows creators to build complex characters up to 1 MB in size with multiple intro scenarios and programmable Scripts that trigger dynamic lore or behavioral rules using whole-word matching and built-in debugging tools.
- **Granular LLM Generation Controls:** Exposes low-level sampling parameters in the chat menu, including custom Top-K, Top-P, frequency and repetition penalties, forbidden vocabulary lists, and response prefill instructions.
- **Custom CSS Profiles & Chat Typography:** Features an interactive CSS editor with guided tutorials for styling creator profiles and character cards, alongside per-chat text settings to customize fonts, italics styling, and accent colors.

**Strengths:** Core JanitorLLM chat experience remains genuinely free with unlimited messages and ~9K context tokens; Supports both one-click built-in third-party model routing (Janitor+ Router) and full BYOK custom proxies; Industry-leading creator toolkit featuring 1 MB character limits, conditional Scripts, and forbidden-word controls; Transparent sampling settings (Top-K, Top-P, repetition penalties) and reasoning 'thinking box' inspection

**Limitations:** Janitor+ Router is restricted to paid $12.99/mo subscribers on the web and still bills extra per token used; Free-tier JLLM users can experience slower response speeds or generation inconsistencies during peak traffic; Steep learning curve for casual users navigating proxy endpoints, token limits, and advanced sampling sliders
