The short answer
The 2026 stack for AI-assisted literature review combines Marker (38,192 stars, Apache-2.0) - which converts PDF papers into clean, structured Markdown - with GPT Researcher (28,775 stars) or any LLM for synthesis. The result: a cited, organized review in hours instead of weeks.
Step 1 - Convert PDFs with Marker
pip install marker-pdf
marker_single paper.pdf --output_dir ./papers_md
# or batch: marker /path/to/papers/ --output_dir ./papers_md
Marker handles equations, tables, and multi-column academic layouts far better than naive text extraction - critical for technical papers.
Step 2 - Build a searchable corpus
Converted Markdown goes into a local RAG setup (AnythingLLM, see our local document chat guide) or a plain folder + LLM prompts. This gives you:
- Ask questions across all papers at once: "which papers used LoRA for medical imaging?"
- Extract per-paper summaries consistently.
- Find contradictions between papers.
Step 3 - Synthesize with structure
Prompt an LLM with the classic review skeleton:
- Scope and inclusion criteria.
- Thematic grouping (methods / datasets / results).
- Comparison table of key papers.
- Gaps and future work.
GPT Researcher can also bootstrap the initial paper list by searching Arxiv and PubMed with citations.
Honest limitations (2026)
- AI summaries can flatten nuance - always read the papers that matter most to your thesis.
- Citation integrity depends on your review: the AI can misattribute findings if the source PDFs are poor.
- Payload size: 40 papers is fine; 400 needs chunking strategy and more time.
FAQ
Is this acceptable for academic integrity? Using AI for organization and first drafts is common; the analysis and final writing must be your own - check your institution's policy.
What about paywalled papers? Use papers you have legal access to; Marker works on any PDF you possess.
How long does it take? 20-40 papers: one focused day, including verification reads.
