## Frequently Asked Questions

### How to Set Keyboard Shortcuts

Set this in the extension management page, for example:

- chrome [chrome://extensions/shortcuts](chrome://extensions/shortcuts)
- firefox [about:addons](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.

### API (Ollama, etc.) Test Failure

Common reasons for API test failures include:

- Incorrect address:
  - For example, `Ollama` has a native API address and an `Openai`-compatible address. This plugin currently supports the `Openai`-compatible address and does not support the `Ollama` native API address.
- Some AI models do not support batch translation:
  - In this case, you can choose to disable batch translation or use a custom API.
  - Alternatively, you can use a custom API. For details, please refer to: [Custom API Example Documentation](https://github.com/fishjar/kiss-translator/blob/master/custom-api_v2.md)
- Some AI models have inconsistent parameters:
  - For example, the parameters of the `Gemini` native API are highly inconsistent. Some model versions do not support certain parameters, leading to errors.
  - In this case, you can modify the request body using a `Hook`, or replace it with `Gemini2` (an OpenAI-compatible address).
- The server restricts cross-origin access, returning a 403 error:
  - For example, `Ollama` requires adding the environment variable `OLLAMA_ORIGINS=*` when starting. See: 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.

### How to set up a hook function for a custom API

Custom APIs are very powerful and flexible, and can theoretically connect to any translation API.

Example reference: [custom-api_v2.md](https://github.com/fishjar/kiss-translator/blob/master/custom-api_v2.md)

### How to directly access the Tampermonkey script settings page

## Future Plans 

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

- [x] **Batch Text Requests**: Optimize request strategy to reduce translation API calls and improve performance.
- [x] **Enhanced Rich Text Translation**: Support accurate translation of complex page structures and rich text content.
- [x] **Advanced Custom/AI Interfaces**: Add support for context memory, multi-turn conversations, and other advanced AI features.
- [x] **Fallback English Dictionary**: When translation services fail, fall back to a local dictionary lookup.
- [x] **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](https://github.com/fishjar/kiss-translator/issues) or submit a PR!
