Prompt Grammar AI bởi Comss

Prompt Grammar AI is a fork of Language Improver by Dhananjay Kumar, extended under the Mozilla Public License 2.0.

Select any text and use the right-click menu to improve writing, fix grammar, or translate it in place. A separate option translates the entire page, including dynamically loaded content such as infinite-scroll feeds.

Added in this fork (compared to the original Language Improver):

• Full-page translation with MutationObserver — works on infinite-scroll feeds and single-page apps
• Google Gemini API support alongside OpenRouter (200+ models)
• Per-function customizable prompt templates
• Correct multilingual behavior — grammar and style improvements stay in the original language, no forced English output
• New in 2.1.0: Google AI Mode — opens selected text in Google AI search in a background tab, no API key needed
• New in 2.1.0: Custom Prompt — define any instruction; the AI follows it exactly; HTML output is inserted as real HTML in editable fields (e.g. CKEditor)

  Requires an API key from openrouter.ai or aistudio.google.com. Both offer free tiers.
