Find real sources for your question AI Research

Search an open index of scholarly works, filter by year, open access and citations, and cite any result in seconds.

Searches OpenAlex, an open index of scholarly works, with Semantic Scholar as a backup.

Real papers, not invented references

Every result comes from OpenAlex, an open index of scholarly works, with Semantic Scholar as a backup. Titles, authors, years, journals, citation counts and open-access links are shown exactly as the index records them.

The short AI note under a result is written only from that work's abstract. It helps you decide what to open first. It is not a summary of the full paper, so read the source before you rely on it.

How to use the AI Research Tool

  1. Ask a question

    Type a topic or a research question in plain words.

  2. Filter the results

    Limit the years, keep only open-access works, set a minimum number of citations, or sort by relevance, citations or date.

  3. Open and cite

    Open the paper or its free copy, then cite it in APA, MLA, Chicago, Harvard, IEEE and more, or add it to your bibliography.

Research tool FAQs

From OpenAlex, a free and open catalog of scholarly works. If it is unavailable, ZeroTell searches Semantic Scholar instead, and the results say which index answered.

No. The list comes straight from the index. The model only writes the one-line note, and only from the abstract it is shown. Works without an abstract get no note.

Not necessarily. The label is the index's work type. Preprints are marked as not peer reviewed; for anything else, check the journal's review policy if it matters for your work.

Yes, a few searches each day are free, with or without an account. Pro plans include searches under fair use; without a plan, credits you already have pay for a search (one credit each).

"Plan your research" turns your question and notes into a research brief, an outline or a list of questions. It does not search anything; use "Find sources" for real papers.
