About

SA_agent

Features
Read full description

SA_agent is a Safari Web Extension for researchers who use Google Scholar on iPhone and iPad. It adds local journal context to supported result pages. A 7-day free trial, then $4.99 per year, unlocks the extension. Summaries use Apple Intelligence on your device. RESEARCH WITH LOCAL JOURNAL CONTEXT โ€ข See color-coded SJR quartiles and available JCR, CAS, CiteScore, indexing, and discipline-list fields beside supported Scholar results. โ€ข Match journals on device with an ISSN hit, a result cache, a Bloom filter, a sorted prefix index, a token index, and a trigram index that checks plausible titles with a banded edit-distance test. โ€ข Search more than 35,000 bundled journals by title or ISSN without contacting a journal-ranking service. โ€ข Choose, reorder, and hide ranking badges to match your workflow. โ€ข Import a private custom journal list from CSV or JSON and display its ranks alongside bundled data. Custom datasets stay in extension-local storage. OPTIONAL AI RESEARCH TOOLS โ€ข Create focused paper summaries from Scholar results. โ€ข Choose a 30โ€“1,000-word target and Academic, Formal, or Casual tone. โ€ข Regenerate or improve a summary, then copy it or download it as text. โ€ข Connect an optional Zotero Web API account, format up to 50 library items in APA, Chicago, MLA, or Harvard style, and generate a downloadable literature-review draft. โ€ข Summaries and literature reviews are created with Apple Intelligence on your device. SUBSCRIPTION Start a 7-day free trial in the SA_agent app, then subscribe for $4.99 per year. Apple confirms the price before the trial begins. Cancel during the trial and you will not be charged. An active trial or subscription unlocks Scholar rankings, Journal Search, custom datasets, summaries, and Zotero literature reviews. You do not paste an extension token. Earlier credit packs do not unlock the subscription. PRIVACY BY ACTION Journal matching, ranking lookup, and custom datasets are processed locally. Summaries and literature reviews use Apple Intelligence on your device and are not sent to an SA Agent server. Optional Zotero credentials are used for Zotero API requests.

Open the extension Options page to choose badges, search journals, add a custom dataset, or connect Zotero.
