Summary card
Papers in the last 5 years, citations, OA, and DOI coverage — one card at the top of the profile. Rates are shown as "X / Y".
Papers not found on researchmap: 7
Maintenance report
Cross-checks the OpenAlex author record or your own Google Scholar BibTeX to find papers missing from researchmap — and exports a file you can feed straight into researchmap import.

FAQ
Is this a research evaluation tool?
No. KenLens visualizes public metadata and supports profile maintenance; it does not compare, rank, or score researchers. We support the spirit of DORA (the San Francisco Declaration on Research Assessment).
Where does the data come from?
From the researchmap public API and the public metadata published by OpenAlex, Crossref, and Unpaywall. KenLens is not affiliated with any of these services.
Why do some papers show no citation count?
It depends on the coverage of external databases — it does not indicate any issue with the paper itself.
Why does the citation count differ from Google Scholar?
They count different populations. Google Scholar also counts citations from a very broad range of web documents — preprints, bulletins, theses — so its numbers tend to be the largest of any database. KenLens aggregates OpenAlex public data (scholarly works with structured reference lists); neither is wrong. That is exactly why every number is shown with its source and retrieval date.
Is my browsing history collected?
No. KenLens only makes the network requests needed to process the researchmap page you are viewing, plus a roughly once-daily fetch of its operational config. It does not collect your browsing history.
