Just another wrapper that requires my own OpenAI key.
Handy quick action popup if you already have credits.
UI feels a bit half-baked and extension permissions are heavy.
Stopped working after the latest browser update.
AI-synthesized perspectives grounded in live site inspection, pricing structure, and category benchmarks — presented as editorial viewpoints rather than individual customer testimonials.
Detects the language of your selected text and translates it into your chosen primary or secondary language without leaving the page.
Select text or use a hotkey to have GPT expand associations and finish or elaborate on your sentence, with Tab-key acceptance for speed.
Condenses a selected block of text into its key points so you can grasp the main ideas at a glance.
Refines grammar, sentence structure, and readability so the result reads professionally.
Your OpenAI API key is kept in the browser's local storage, so credentials are not sent to a third-party server.
Text Assist is a small browser extension published on the Chrome Web Store that brings GPT-based text actions to whatever page you are already reading or writing on. Instead of copying text into a separate chat window, you select a passage, trigger the extension, and get a rewritten, translated, or summarized result in place.
The extension covers a practical set of everyday writing tasks. It can translate between your primary and secondary language with automatic language detection, complete or expand a sentence from a short prompt, summarize long passages into key points, and polish grammar and readability. Completion can also be triggered with a hotkey and accepted with the Tab key for fast flow.
Text Assist is bring-your-own-key: you supply an OpenAI API key, and the extension keeps it stored locally in the browser rather than on a server. It is deliberately minimal, published by an individual developer, and aimed at people who already pay for OpenAI access and want a faster, in-page way to use it.
Highlight a long article or paper paragraph and instantly pull out the key points instead of re-reading it several times.
Read foreign-language pages and translate selected passages into your working language without switching to a separate tool.
Expand a short bullet into a full sentence or clean up grammar in a draft before you send it.
