Solo Researchers

Trace claims back to original passages so your work stays verifiable, organized, and citation-ready.

Three steps. That's it.

Scope your notebook, add material, then ask questions with citations.

1

Create a notebook

Start a notebook for each class, project, or topic. The notebook becomes your scope — what Thea is allowed to use.

2

Add your material

Drop in PDFs, docs, and slides. Thesis prepares them so answers can point back to the exact page.

3

Ask and verify

Ask for summaries, comparisons, or practice questions. Every response includes citations so you can check the source.
