## TL;DR

BioSkepsis is an AI research paper summariser built for biomedical and life-science literature. It produces cited, verifiable summaries of a paper's aims, methods, findings, effect sizes, limitations, and conflicts of interest — never invents numbers, and declines to answer when evidence is insufficient. Works on papers you upload (PDFs, manuscripts, lab notes) and on any of 40M+ indexed biomedical papers. Free tier with 100 papers per session, no credit card, no sign-up fee.

## The problem with generic AI summarisers

Most "AI article summariser" tools were trained on the open web and summarise at the abstract level. For a news story that is usually fine. For a biomedical paper it is not, because:

- **Abstracts omit critical information.** Sample size, control arms, exclusion criteria, effect-size confidence intervals, and limitations usually live in the methods and discussion — not the abstract. A summary that only reads the abstract will under-report risk and over-report confidence.
- **Generic LLMs invent numbers.** When asked for a specific figure that is not in-context, a generic summariser will often confabulate a plausible value. For a clinical claim, a fabricated odds ratio is a retraction waiting to happen.
- **They misattribute findings across papers.** Without retrieval grounded to a specific source, summaries blend claims from multiple documents and cite the wrong one.
- **They cannot flag biological context.** "This trial showed efficacy in a mouse model" is not the same claim as "this trial showed efficacy in humans." Generic summarisers routinely conflate them.

If your summary feeds a grant application, a systematic review, a journal club, or a clinical decision, any of the above is unacceptable.

## How BioSkepsis summarises differently

BioSkepsis is the best AI for summarising research papers in the life sciences specifically because it was built for them. Four design choices matter:

### 1. Full-text reasoning, not abstract-only

BioSkepsis reads the methods, results, supplementary materials, and discussion — not just the abstract. Effect sizes, sample sizes, inclusion/exclusion criteria, statistical tests, and limitations are surfaced in the summary because they are surfaced during reasoning.

### 2. Grounded in peer-reviewed sources

Every claim in a summary traces back to a specific passage in a specific paper. Click any claim to jump to the cited sentence. No invented references, no fabricated DOIs.

### 3. Biology-native knowledge graph

Retrieval and disambiguation use Gene Ontology, MeSH descriptors, gene symbols, and pathway relationships. A query for "BRCA1" will not return unrelated papers that happen to mention the string — it will return papers where BRCA1 is a biologically relevant entity.

### 4. Declines when evidence is insufficient

If you ask for a number the paper does not report, BioSkepsis says so. It does not invent one. This is the single biggest reliability difference against general-purpose LLMs.

## Use cases

### Summarise a PDF you uploaded

Drag and drop a PDF — a preprint, a grant, an unpublished manuscript, or a supplementary methods file. BioSkepsis produces a structured summary covering:

- Research question and hypothesis
- Methodology and controls (including n, statistical tests, blinding)
- Primary findings with effect sizes where reported
- Secondary and exploratory findings
- Limitations stated by the authors
- Declared conflicts of interest and funding sources

### Summarise the top papers for a query

Ask a question like "what is the evidence for GLP-1 receptor agonists in non-diabetic obesity?" BioSkepsis retrieves the most biologically relevant papers from its 40M-paper corpus and returns a synthesised summary with inline citations to each source paper. Use this as the first pass of a literature review.

### Batch summarise a reading list

Paste a list of DOIs, PMIDs, or titles and BioSkepsis produces a uniform research paper summary for each — same structure, same fields, same citation format. Useful for journal clubs, lab meetings, and systematic-review screening.

### Summarise and compare methods across RCTs

Ask for a comparative scientific article summary across a set of randomised trials: BioSkepsis extracts the methods fields (arms, n, primary endpoint, follow-up) into a side-by-side view so differences in design are visible before differences in outcome.

| Feature | BioSkepsis | Elicit | SciSpace | ChatGPT | Scholarcy |
| --- | --- | --- | --- | --- | --- |
| Domain focus | Biomedical & life science | General academic | General academic | General | General |
| Full-text reasoning | Yes | Higher tiers | Yes | Depends on upload | Yes |
| Grounded citations per claim | Yes | Yes | Yes | No (unless browsing) | Partial |
| Declines when evidence missing | Yes (explicit) | Partial | Partial | No | No |
| Biology-native retrieval | Yes (GO + MeSH + genes) | No | No | No | No |
| Ongoing free tier | Yes (100 papers/session) | Capped credits | Freemium | Freemium | Freemium |

For biomedical work where citations must be verifiable and methods must be preserved, BioSkepsis is the best AI summariser for academic articles in the life sciences. For non-biomedical disciplines or for workflows centred on structured multi-paper column extraction, another tool may fit better.

## What BioSkepsis preserves (and what it will not do)

**Preserved in every summary:**

- Research question and hypothesis
- Methods and controls — study design, sample size, statistical tests
- Primary and secondary findings with numbers where reported
- Effect sizes and confidence intervals (where reported)
- Limitations (authors' and structural)
- Funding and conflict-of-interest declarations
- Model system — species, cell line, in vitro vs in vivo vs clinical

**What BioSkepsis will not do:**

- Invent a number that is not in the paper
- Generate a citation it cannot retrieve
- Generalise from a mouse study to humans without flagging it
- Paper over contradictory findings across cited sources

## Frequently asked questions

### What makes an AI paper summariser reliable for research?

Three things: (1) it reads the full text, not just the abstract; (2) every claim links to a verifiable passage in a named source; (3) it declines to answer when the evidence is insufficient, rather than filling the gap with plausible-sounding text.

### Can BioSkepsis summarise a PDF I upload?

Yes. Drop in a PDF — published paper, preprint, manuscript, or supplementary file — and BioSkepsis produces a structured summary grounded to passages inside that specific document. No data leaves your session for a use other than answering your question.

### Is there a free AI paper summariser?

Yes. BioSkepsis has an ongoing free tier with a cap of 100 papers per session, no time limit, no credit card. That covers most single-paper and small-reading-list use cases.

### How long a paper can BioSkepsis handle?

Full-length research papers including supplementary materials. Long manuscripts (theses, book chapters) are also supported — the summary uses the same structured schema regardless of length.

### Does every claim in the summary cite a source?

Yes. Every claim is traceable to a passage in a named paper or in the file you uploaded. If the evidence is not there, BioSkepsis says so rather than inventing a citation.
