Page Prefetching
Pre-translate upcoming pages while you read, so the next page loads instantly.
Pre-Translate the Next Pages
Configure the extension to prefetch and translate upcoming pages in the background. When you navigate to the next page, the translation is already cached and appears instantly — no waiting for OCR and AI processing.
Configuration
Adjust the prefetch slider (0–10) in the General tab Advanced section:
- 0 — No prefetching (default)
- 1–10 — Pre-translate that many pages ahead
How It Detects Next Pages
The extension uses two methods to find the next page URL:
- URL heuristics — Increments query parameters (e.g.,
?page=2to?page=3) or trailing path numbers (e.g.,/3/to/4/) - DOM detection — Looks for next-link elements (
a[rel="next"], common manga reader selectors, Japanese "next" text)
Each prefetched page uses your quota or credits
Prefetching spends translation quota for every page it pulls, even ones you never scroll to. On the default Hosted Server backend that's pages from your weekly allotment; on BYOK OpenAI it's tokens billed to your account. Start with a low number (1–2) and increase if you binge-read in long sessions.
