How it works
Three steps to a structured, cited summary
Purpose-built for research papers. Understand if a source is relevant to your research in less than 1 min.
Upload PDF or paste a URL/DOI
No account needed for your first paper. PDF, arXiv, DOI, J-STAGE, and CiNii URLs all supported.
AI indexes the source securely and anonymously
Kenkyu.ai processes your paper anonymously. No data used for AI training, and PDF files deleted immediately after indexing.
Read the summary with every claim linked to its source passage
Click any citation chip to expand the original passage. Quote it with confidence, no hallucinated facts, no misattributed findings.
Privacy & your papers
Your unpublished work stays yours
Upload confidential drafts, peer-review manuscripts, internal lab papers without compromise.
Safe for pre-submission manuscripts
Drop in a draft before peer review. We never train on uploaded papers so your unpublished findings stay yours.
Held only for your session
Anonymous sessions expire in 24 hours. Files are deleted automatically.
No account required for your first paper
Sensitive uploads can skip registration entirely. Anonymous sessions get a full summary plus 3 grounded follow-up questions.
Encrypted in transit
All traffic is protected with TLS, and uploads are kept in an isolated anonymous storage environment. AI processing runs on API-tier endpoints that are never used to train models.
Why Kenkyu.ai
How it compares to ChatGPT, NoteGPT, PaperGuide, and others
A side-by-side view of what each tool actually delivers when you upload a full research paper.
Built for summarization-first workflows
From 30 papers a week to a shareable triage pile
Fast summarizations for when you don't yet know which papers are worth deep reading. Use Kenkyu.ai to triage first, then dive in.
Lit review at scale
PhD candidate triaging 30 papers per week
Every paper looks promising in the abstract; full reading 30 a week is impossible. Picking the wrong 5 to read deeply wastes the month.
Get a structured summary for each in seconds. Promote only the papers whose Methods and Results survive the summary.
Conference paper prep
Citing related work fast, without misrepresenting findings
You need to cite ten adjacent papers in your related-work section, but skimming-then-paraphrasing risks subtle misattribution.
Pull a citation-linked summary, then verify each claim against the source passage before it lands in your manuscript.
Journal-club lead
Prepping IMRAD notes shareable with the group
Re-reading an English paper alone and producing usable group-discussion notes is a full evening's work.
Drop the PDF, share the auto-generated summary, and use 3 follow-ups to surface the discussion-worthy gaps.
Cross-disciplinary investigator
Reading outside your field, where methods and assumptions need to be clear
You can parse the conclusions, but the methods section is full of unfamiliar machinery and untested assumptions.
The AI summary surfaces methods and assumptions for you. Follow-up Q&A drills into the parts you don't recognize.
