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. The Notebook keeps track of your reading, like the seal books travellers have stamped from temple to temple: β’ Fifty-three seals to earn by reading, in three rarities (Ink, Vermilion and Gold), a few of them secret β’ Six familiars of ink and paper, painted with a brush: each hatches from an egg that drinks the ink of your reading, then grows with you β’ A forgiving daily streak, a weekly goal, and challenges for the month β’ The ink calendar, your ex libris and the year's Almanac, to share as pictures β’ "What to read tonight?": the omikuji draws a title from your pile β’ No account, no leaderboard: it all stays yours, and "Plain reading" hides the play when you just want to read BEYOND THE APP β’ The Resume reading widget takes you back to the right page β’ Siri, Shortcuts, Spotlight search and quick actions on the app icon THE FINE PRESS (PREMIUM) β’ Offline downloads, from your Komga or Suwayomi server too, with predictive download and storage management β’ iCloud sync across iPhone and iPad β’ New chapters in the background and the visual selector β’ Continuous reading, on to the next chapter by itself, two-page spreads, color filters, page previews β’ Detailed statistics, unlimited history, the whole year in the ink calendar, the Almanac month by month, the seals of the seasons and Yuki-usagi, the snow hare β’ Streak, seal and familiar widgets; the Papier, Hanko and Sakura app icons, and the familiars' icons β’ Incognito mode, App Lock with Face ID, Touch ID or a passcode, the Sakura theme and an automatic theme Seals, familiars, the streak, the weekly goal, the omikuji and the Resume reading widget stay free.

Audissey

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 Audisseyβs 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 Appleβs 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 βreadβ 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 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.
