KISS Translator

New Version Preview:

After a period of intermittent development, the planned features for the new version are essentially complete. The main new features are as follows:

• Core Translation Logic Refactoring:

  • Supports both automatic text detection and manual selection modes.
  • The automatic text detection mode enables complete translation for the vast majority of websites without the need to write specific rules.
  • The previous manual rule mode has been retained for meticulous optimization on specific websites.
  • Supports rich text translation, preserving links and other text styles from the original content as much as possible.
  • Optimize the display effect of showing only translated text (hiding original text).

• API Refactoring:

  • Supports adding and deleting an arbitrary number of APIs.
  • Supports aggregating text for sending, reducing the number of calls to the translation API and improving performance.
  • Supports the built-in Chrome AI translation API, enabling AI-powered translation without an internet connection.
  • Supports AI contextual conversation memory to enhance translation quality.
  • All APIs support advanced features such as hooks and custom parameters.
  • Added support for Azure AI translation interface.

• Optimized YouTube Subtitle Support:

  • Supports translating video subtitles with any translation service and displaying them bilingually.
  • Includes a built-in basic algorithm for subtitle merging and sentence splitting to improve translation results.
  • Supports an AI-powered sentence splitting function to further enhance translation quality.

• English Dictionary Redundancy:

  • Added Bing and Youdao dictionaries.
  • Fixed the vocabulary collection feature.

• User Experience Optimization:

  • The pop-up translation box for selected text now supports simultaneous translation by multiple services.
  • The translation control panel has been updated with many new quick-toggle functions.
  • Added a Playground page for convenient API debugging.

Note: Due to extensive refactoring, the configuration file for the new version is not backward compatible with the old version. Therefore, please back up your data manually before upgrading. Furthermore, do not import old configuration files after upgrading to the new version.

Frequently Asked Questions

How to Set Keyboard Shortcuts

Set this in the extension management page, for example:

• chrome chrome://extensions/shortcuts
• firefox about:addons

What is the priority order of rule settings?

Personal Rules > Subscription Rules > Global Rules

Among these, Global Rules have the lowest priority but are very important as they serve as the default rules.

Local Ollama interface cannot be used

If encountering a 403 error, refer to: https://github.com/fishjar/kiss-translator/issues/174

Custom API doesn't work in Tampermonkey scripts

Tampermonkey scripts require adding domains to the whitelist; otherwise, requests cannot be sent.

Future Plans

This is a side project with no strict timeline. Community contributions are welcome. The following are preliminary feature directions:

• Batch Text Requests: Optimize request strategy to reduce translation API calls and improve performance.
• Enhanced Rich Text Translation: Support accurate translation of complex page structures and rich text content.
• Advanced Custom/AI Interfaces: Add support for context memory, multi-turn conversations, and other advanced AI features.
• Fallback English Dictionary: When translation services fail, fall back to a local dictionary lookup.
• Improved YouTube Subtitle Support: Enhance merging and translation experience for streaming subtitles, reducing sentence fragmentation.
• Upgraded Rule Collaboration System: Introduce more flexible rule sharing, version management, and community review processes.

If you're interested in any of these directions, feel free to discuss in Issues or submit a PR!
