Summary of findings from Chrome Web Store listing and SmartStudi site: UCG (listed as "UCG: Undetectable ChatGPT — Use GPT Without a Visible Chat on Chrome") is a Chrome extension that routes prompts to ChatGPT and returns responses without presenting a visible chat UI. The store listing shows version 1.1.5 (updated January 18, 2025), file size 153 KiB, and support for 14 languages. Core advertised features include sending a screenshot of the current tab to ChatGPT, sending selected text from a page, entering a prompt via the browser search bar, viewing ChatGPT replies via a clipboard shortcut (Ctrl+V on Windows, Cmd+V on Mac) to avoid a visible chat UI, and a "human-typing" simulation in Google Docs. The extension requires users to sign up for an account at smartstudi.com. SmartStudi markets a suite of related tools (AI detector, humanizer/paraphraser, "Undetectable AI Chatbot") and promotes claims about evading AI detectors; the SmartStudi site is promotional and includes tools/services beyond this extension. No pricing plans or trial details were found on the Chrome Web Store listing or on smartstudi.com pages located during the review; several directory/listing pages label the extension as "Freemium" or show "No pricing," but no authoritative pricing page was located. The Chrome listing references a privacy policy and includes developer privacy claims (for example, not selling data for unauthorized uses and not using data for creditworthiness evaluations), but the reviewer did not find independent verification of those claims and recommends reading the full privacy policy on the developer site. Other references found during the search include promotional content on smartstudi.com and multiple directory/listing pages and aggregators referencing UCG. Noted risks include the primary advertised capability (making ChatGPT usage non-visible/"undetectable") which could be used to bypass institutional restrictions or academic integrity rules; marketing claims of "undetectability" should be treated skeptically and privacy claims should be independently verified. Recommended follow-ups include retrieving the extension permissions list, extracting the support email and direct links to privacy policy/terms, pulling user reviews and ratings from the Chrome Web Store, searching for security analyses or independent audits, and attempting to find explicit pricing pages or subscription details on smartstudi.com.
