Sumi Book

Sumi is a beautifully crafted, native reader for the manga and comics you already own or have the right to read. Sumi comes empty by design: no catalog, no content, no built-in sources β€” you decide what to read. Import your own files, connect your own server, or add a source by pasting the address of a site you are entitled to access. Sumi brings the reading; the library is yours. A READER, NOT A LIBRARY β€’ Your own .cbz, .cbr, .zip, .pdf and .epub files, from the Files app, AirDrop or Mail β€’ Your own Komga or Suwayomi server β€’ Your own source: paste a site's address, or share a page from Safari β€” no content or site is included: Sumi recognizes common site software as soon as you paste an address β€’ "Test this source" shows which step fails DESIGNED FOR READING β€’ Ink, dark, and Paper, light: two themes made for long sessions β€’ Paged or vertical-scroll reading, right to left for manga, and Guided View, panel by panel β€’ Resume: the titles you're reading at the top of your Library, back to the exact page β€’ An end-of-chapter page, bookmarks, and tap zones your way β€’ Rate titles from one to five seals and keep a private note β€’ On iPad, Sumi follows the size of its window, and the keyboard turns the pages β€’ Free backup and restore of your whole collection THE NOTEBOOK Four tabs: Library, Browse, Notebook and Settings.

About

Audissey

Features
Read full description

Audissey turns web fiction, articles, and public-domain books into audio you can listen to anywhere β€” on your commute, while cooking, or with the screen locked. Open a chapter in Audissey’s browser and tap Read to hear it immediately, or tap Extract to save it. Paste a link, paste the text yourself, or subscribe to an RSS feed. Audissey imports the story, cleans it up, and reads it aloud. Build a personal library, organize stories on shelves, and pick up right where you left off. LISTEN YOUR WAY β€’ Read a page in the browser without saving it, with the current sentence highlighted as it is spoken β€’ On a single-page book, such as a Project Gutenberg title, listening continues into the next chapter β€’ Import from a link, pasted text, an RSS feed, or the in-app browser β€’ Save a browser page as fiction or as an article, and name the new novel or collection β€’ Add a chapter to a novel you already have, with its own title and number β€’ Bookmarks and ready-made starting points for public-domain libraries and major news sites β€’ Play, pause, and skip with lock-screen controls β€’ Tap Read on the player to jump back to the chapter and follow along β€’ Adjust playback speed to match your pace β€’ Ambient listening screen for a calm, hands-free experience β€’ A chapter imported from the web remembers its page, and you can open that page from the chapter settings. SMART LIBRARY β€’ Auto-import checks for newly published chapters on stories you follow β€’ RSS subscriptions bring in new articles from sites you follow β€’ Automatically split massive, single-page stories into chapters when you import them β€’ Search across stories and chapters β€’ Organize novels and article collections into custom shelves β€’ Track progress chapter by chapter β€’ Syncs across your devices with iCloud BUILT-IN AUTHOR SUPPORT When a chapter includes a Patreon or PayPal link, Audissey shows it in the reader so you can support the author. Those links stay out of the audio, so they never interrupt the story. INTELLIGENT, EXPRESSIVE VOICES Choose Apple’s built-in voices or switch to Audissey Neural Voices, our on-device neural voice engine. Speech is generated on your iPhone, so your stories stay private. β€’ Context-aware pronunciation: words like β€œread” are spoken the way the sentence means them β€’ Dynamic expression adds emphasis and pacing to action and dialogue β€’ Custom dictionary for character names and world-building terms β€’ Assign a narrator to each story from its settings Audissey Neural Voices currently support English. More languages are in progress. β€’ Audissey Neural Voices include American and British English, and they stay cooler through long listening. ADVANCED API INTEGRATIONS Connect your own API keys on your device: β€’ Speaker detection: use an OpenAI, Gemini, or Anthropic key to identify who is speaking. On a browser page, each speaker can have a voice without saving the page. In a saved novel, a voice you assign is used for that character throughout the story. β€’ Page selection: the same key can suggest how to capture the title and body of a page, so similar pages on that site are easier next time β€’ ElevenLabs: stream realistic, multi-cast character voices into your listening queue. With your own key, choose the speech model in Settings. AUDISSEY PRO A one-time purchase. Pro removes ads, lets you import unlimited chapters at once, and adds Cache Ahead so Audissey Neural Voices can keep playing smoothly with the screen locked. Audissey is for readers who want to hear their favorite stories β€” not another streaming subscription.

Verdict

The call

The clearest difference is ads: Sumi Book at none against Audissey's shown. Sumi Book also leads on iOS requirement (15.1 vs 26.5). Audissey's advantage is update cadence (every 2 days vs every 5 days). On price, in-app purchases and device support there is nothing between them.
