Proofread rules

Proofread rules are user-defined find-and-replace patterns. They're useful for:

  • Fixing OCR artifacts in older scanned EPUBs
  • Expanding abbreviations so TTS reads them correctly (e.g., "LLM" → "large language model" for audio only)
  • Applying a consistent typographic pass (dumb quotes → smart quotes)

Open Book Menu → Proofread. Each rule has:

  • Pattern — plain text or a regular expression
  • Replacement — what to substitute
  • Match options — case-sensitive, whole word only
  • ScopeSelection, Book, or Library
  • Apply toDisplay, TTS-only, or both

Rules run in priority order (lower number first). TTS-only rules are the right choice when you want the audio to read "LLM" as "large language model" while keeping "LLM" in the visible text.

Test a rule on a selection first (scope = Selection) before promoting it to the whole library.

File associations

Setting Readest as the default app for EPUB/PDF/etc. lets you double-click a book from your file manager to open it in Readest.

  • macOS — right-click a book → Get InfoOpen with → pick Readest → Change All.
  • Windows — right-click a book → Open withChoose another app → pick Readest → check Always use this app.
  • Linux — depends on desktop environment. GNOME: right-click → PropertiesOpen With → set Readest as default. KDE: similar.

On mobile, the OS handles file associations through the share sheet — "Open in Readest" appears wherever a book file can be shared.

Verify release files

Desktop releases are signed with minisign. Verifying confirms the installer came from the Readest maintainers and wasn't tampered with in transit. Each download on the Releases page has a matching .sig file. Full platform-specific examples and key-extraction steps are on the Verifying Readest Release Files wiki page.
