4 use cases

  • Ask cited questions across your own PDF library

    Run Thesys locally, upload papers, and get chat answers that jump to the exact passage in each PDF.

    View prompt
    Use the Sreehari05055/thesys-core repo to set up a local research workspace with Docker, set OPENAI_API_KEY and EMAIL in backend/.env, and upload the PDFs in <path-to-pdf-folder>. Report the chat answer to the question <your question> and the citation it links to. Verify that clicking the citation opens the highlighted passage in the PDF preview.
  • Find open-access papers and add them to your library

    Search OpenAlex and arXiv in one pool, preview records, and add the useful ones to your Thesys library.

    View prompt
    Use the Sreehari05055/thesys-core repo to start the Docker workspace, search Discover for <your topic>, and add the five most relevant open-access papers to the library. Report the titles and links of the papers added. Verify that each added paper appears in the library list.
  • Check whether two papers agree on a specific claim

    Select two library PDFs, turn on Compare, and see which retrieved passage pairs support or contradict a claim.

    View prompt
    Use the Sreehari05055/thesys-core repo with a valid TYPESAFE_API_KEY to compare the two library papers <paper A> and <paper B> on the claim <claim text>. Output the list of passage pairs with their labels and confidence values. Verify that each pair shows the matching passages in both PDFs.
  • Export your library as a bibliography file

    Turn your Thesys library into BibTeX, RIS, EndNote, or CSV for your writing or reference manager.

    View prompt
    Use the Sreehari05055/thesys-core repo to open the library, select the papers on the topic <topic>, and export them as <BibTeX, RIS, EndNote, or CSV>. Output the file name and entry count. Verify that the file opens and contains one entry per selected paper.

How to use Thesys Core

  1. Check you have what it needs: Docker, or Python 3.11+ and Node.js 20+ for the local setup; An OpenAI API key for chat; A contact email for the EMAIL setting used by citation lookup.

  3. Run cp backend/.env.example backend/.env and set OPENAI_API_KEY and EMAIL in backend/.env.
  4. Run docker compose up --build from the repo root and wait for the first build to finish.
  5. Open http://127.0.0.1:5000 in a browser and upload one or more PDFs to the library.
