What are you writing today?
Thezis helps you write research papers faster, section by section, with AI that assists instead of taking over. Get your research papers done today.

Why.
Here's the thing about research.
You read references. You highlight PDF files. You take notes. You think you're being organized. But then you sit down to actually write — and everything falls apart.
Your highlights are stucked in a PDF app. Your notes are in a spreadsheet somewhere. Your best quote? You remember reading it. You just can't find it. So you end up doing the whole thing twice — once to research, once to re-find your research.
People have tried to fix this. Spreadsheets. Citation managers. Color-coded folders. But these aren't solutions. They're just more places for your work to get lost.
The problem was never organization skills. But it was the tools.
So that's why we built Thezis.
Upload your PDFs. Make highlights. Pick and cite highlights. Everything lives in one place. No switching between apps.
All the research tools you need.
Reference library.
To keep your sources organized.
Before
- PDFs scattered across Downloads, Drive, and email
- Renaming files to author_year_title.pdf
- Spreadsheets to track what you've read
- Switching between Zotero, browser tabs, and your editor
- Losing track of which PDF had that one paragraph
After
- Every project gets its own reference library
- Drag and drop PDFs or upload in bulk
- Metadata auto-extracted — title, authors, year, DOI
- Built-in PDF viewer — read, highlight, and annotate without leaving the app
Search scholarly articles.
Find papers across 15+ databases without leaving the app.
Before
- Jumping between Google Scholar, PubMed, arXiv, and your school's database
- Not knowing which papers to even search for
- Finding a paper then hunting for the PDF separately
- Manually entering title, year, and authors for each source
After
- One search across 15+ databases — arXiv, PubMed, Nature, Springer, IEEE, and more
- AI suggests foundational, adjacent, methodological, and emerging papers
- Suggestions adapt to your paper title and research field
- Find a paper, upload its PDF — metadata auto-fills
- Papers go straight into your reference library, ready to read and highlight

AI editor.
Describe what you want. AI writes it from your sources.
Before
- Staring at a blank Google Doc
- Alt-tabbing between your notes and your draft
- Copy-pasting quotes and losing track of which paper they came from
- Paying for a separate AI tool that hallucinates sources
After
- Break your paper into sections — easier to focus on one idea at a time
- Write in a rich text editor with auto-save
- Edit mode — AI writes and revises directly in your section
- Ask mode — get feedback, find gaps, brainstorm without changing text
Introduction
Sleep plays a critical role in memory consolidation, transforming labile short-term memories into stable long-term representations (Walker, 2017). Research over the past two decades has established that both slow-wave sleep and REM sleep contribute distinct mechanisms to this process.
During slow-wave sleep, hippocampal sharp-wave ripples coordinate with thalamocortical spindles to reactivate and redistribute memory traces to neocortical networks...
