OtakuWorld

Discord Link There's a discord now!!! This is something that will probably be changed and modified since it's the first time I've done this.

For the nightly release, go here

A combined version of my MangaWorld and AnimeWorld apps. This was created because there were a ton of shared elements between the two apps so I combined them, allowing two separate apps but a lot of the same base logic.

These apps do not contain ANY sources themselves. In order to pull sources, the apps do contain some default sources.

Right now, we do support cloud syncing via Firebase, however, that will be going away soon. We are making an alternative way that requires some manual configuration. Using OtakuWorld will allow you to setup a manual configuration! A server is required, fortunately, we have made a basic server that will only work on a local network. Help wanted to help set up a more solid solution!

For MangaWorld: Any sources that work with Mihon will work with MangaWorld...After the bridge is installed.

For AnimeWorld: Any sources that work with Aniyomi will work with AnimeWorld...After the bridge is installed.

Custom Web Scraper

Overview

The :kmpuiviews:koogintegration:customscraper module provides an on-demand HTML scraping pipeline that extracts manga image URLs and anime video stream URLs from any public webpage using an on-device LLM agent.

Architecture Flow

WebScraper.scrape(url)
  └─ Ktor HTTP GET → raw HTML
       └─ HtmlSanitizer → stripped HTML (≤ 8,000 chars)
            └─ LlmMediaExtractor (Koog AIAgent)
                 └─ CustomScrapeKmpChapterModel(urls=[...])

Supported Use Cases

Use Case	What it extracts
Manga chapter page	All <img> src, data-src, data-lazy-src URLs (page images)
Anime episode page	All <video>, <source> URLs and .mp4 / .m3u8 JS variables

Limitations

• No authentication — login-gated pages are not supported.
• No CAPTCHA bypassing — CAPTCHA-protected pages return an empty result.
• No JS rendering — client-side SPA content (rendered after page load) is not visible to the scraper.
• No caching — results are not persisted; each scrape() call is a fresh fetch.
• URL extraction only — downloading or displaying media is handled elsewhere in the app.

Data Model

@Serializable
data class CustomScrapeKmpChapterModel(
    val urls: List<String>,  // extracted media URLs; empty on failure
)

Usage

// Obtain executor + model from your AgentMaker (or any Koog LLM setup):
val executor = MultiLLMPromptExecutor(agentInfo.llmClient)
val model = agentInfo.model

val scraper = WebScraper(executor = executor, model = model)
val result = scraper.scrape("https://example.com/manga/chapter-1")
result.urls.forEach { println(it) }

Technologies
