Thesis Library
AI PDF reader with sentence-level provenance
The Thesis Library holds your papers (uploaded PDFs or open-access full text fetched automatically) and lets you interrogate them with answers traced to the exact source passage.
What Thesis Library does
Full text, automatically
Save a paper and its open-access PDF is fetched, parsed, and indexed through a ten-resolver chain, or upload any PDF yourself, scanned pages included (OCR built in).
Ask the paper, or the corpus
Question one paper or compare it against the wider literature; every answer cites the exact passage it came from, down to the character span.
Quotes that carry their source
Highlight anything and it lands in your quote bank bound to its precise location (page, section, offsets), ready to drop into a chapter with a real citation.
BibTeX in, BibTeX out
Import your .bib (DOI or OpenAlex-keyed) and export later with your own cite keys intact. Your existing LaTeX keeps compiling.
Reading that survives reality
Per-step ingest progress, automatic retries, and honest failure reasons. A stuck upload never spins forever.
Grounded by design
Provenance is sentence-level: quotes and answers bind to stored full-text spans, never to a model's paraphrase.
Who Thesis Library is for
Students reading dozens of papers
Ask a question of one paper or the whole corpus and get answers that point at the exact sentence.
Anyone who quotes sources
Captured quotes are bound to precise character offsets, so a quotation can always be located in the original.
People with an existing reference library
Import BibTeX from Zotero, Mendeley or EndNote with your own cite keys preserved.
How Thesis Library compares
- A generic chat-with-PDF tool
- Summarises confidently, but you cannot check where an answer came from.
- Reading and highlighting by hand
- Reliable and slow, and your notes are not connected to the writing step.
- Library
- Every answer traces to its source span, and the quotes you keep flow into drafting already verified.

Reading papers with sentence-level provenance
The Library reader answers only from a paper's stored full text and points every answer to the exact source span: ask a PDF questions, explain it at your level, and bank quotes that carry a page-accurate citation.

Thesis Library questions
Can I chat with a PDF?
Yes. Ask questions of one paper or your whole corpus. Every answer traces back to the exact sentence it came from, so you can check it rather than trust it.
What is sentence-level provenance?
Each extracted quote is bound to precise character offsets in the source document, so a claim can be located in the original PDF instead of paraphrased from memory.
Can I import papers I already have?
Yes. Upload any PDF, or import a BibTeX library from Zotero, Mendeley or EndNote with your own cite keys preserved.
