Mythos

A web novel library for KOReader.
Browse, track, and export your favourite stories as EPUBs — right on your e-reader.

Free & Open Source · GPL-3.0 · Kobo, Kindle & more

Everything your e-reader was missing

Mythos brings the web novel experience to e-ink — browse, track, and read without ever touching a computer.

Browse & Search

Explore popular novels or search by title directly from your device. No phone required.

Track Novels

Save novels to your library and check for new chapters at a glance with one-tap batch refresh.

Chapter Selection

Pick all chapters, deselect what you don't want, or cherry-pick a custom range with precision.

Flexible Export

Export as a single EPUB, one per chapter, or bundled into volumes — with cover art embedded automatically.

Extension System

Sources are installable plugins. Add support for new sites without updating Mythos itself.

Chapter Caching

Re-opening a tracked novel is instant. Only new chapters are fetched, keeping things snappy.

See it in action

Mythos runs natively on your e-ink device — no companion app, no cloud sync required.

Installation

Installs like any KOReader plugin — copy, restart, done.

  1. Go to the Releases page and download mythos.koplugin.zip

  2. Extract the zip — you'll get a folder called mythos.koplugin

  3. Copy that folder into KOReader's plugins/ directory on your device

  4. Restart KOReader → ToolsMythos

Get started in minutes

Add a source

Go to the Sources tab, tap + Add Repo, and enter the official extension repo. Tap Refresh Index, then tap an extension under Available to install it.

github.com/unitreign/mythosext

Browse or search

Switch to the Browse tab, select your installed source to see popular titles, or tap Search at the top to find something specific.

Track a novel

Tap any novel to open its detail page, then tap Track Novel to add it to your library. Use Refresh on the library screen to check for new chapters across everything you're following.

Export to EPUB

From a novel's detail page, switch to the Chapters tab. Select what you want, tap Export, choose your format, and Mythos builds the EPUB files on your device.

Powered by extensions

Each extension is a small Lua file that teaches Mythos how to talk to one website. Install directly on your device — no Mythos update needed.

The official extension repository is unitreign/mythosext — the best place to start. Extensions are installed from the Sources tab, straight onto your device.

Want to add support for a new site? The full API, required methods, and a worked example are documented in the repo. Finished extensions can be submitted as a pull request to mythosext.
