Models
A mixture of models, cross-checked.
Every frontier model (Claude, GPT, Gemini, Mistral, Grok) alongside our own, routed per sub-task and made to check each other. No single-model bias.
Explore Science vs SciSpace
SciSpace is a broad research copilot with a large agent library. Explore Science runs one deep review of your manuscript, up to 2 hours, and scores it on the same rubric every time you revise.
The short answer
Both tools will now say something about your draft, so the question is what you get back. SciSpace runs a peer-review agent in minutes: three reviewer opinions, ratings out of 10, and an accept or revise recommendation, alongside 200+ agents for screening, compliance and journal fit. Explore Science spends up to 2 hours on a single manuscript and returns one Calibre score out of 100 across eight categories, every reference checked against live databases for whether it supports the claim it backs, and the same rubric reapplied to each revision so you can watch quality move. If you want a fast second opinion inside a wide research toolkit, SciSpace fits; if you want a rigorous, repeatable verdict before submission, choose Explore Science.
Compared July 2026 · from SciSpace's own published materials
Choose Explore Science when
- One Calibre score out of 100 across eight fixed categories, reapplied to every version, so revisions are measurable rather than merely different.
- Every reference checked against live scholarly databases for whether it actually supports the claim it backs, not only whether the DOI resolves.
- A mixture of frontier models (Claude, GPT, Gemini, Mistral, Grok) plus our in-house Explorer One, cross-checking each other on the same manuscript.
- Up to 2 hours on one paper, because depth per run is the point; the review arrives by email when it lands.
- Rosa reads your paper, its review, and the rest of your body of work, so the chat knows your project rather than the literature at large.
Choose SciSpace when
- Natural-language search over an index of roughly 270 million papers, which Explore Science does not offer.
- A peer-review agent returning three reviewer perspectives, a meta-review and a live novelty check in minutes, inside a gallery of 200+ research agents.
- Reading and writing tools Explore Science does not offer: extraction tables across many PDFs, an AI writer, a citation generator, translation, and a browser extension.
- Screening and synthesis infrastructure for systematic reviews: PRISMA flow diagrams, inter-rater agreement statistics, deduplication, and Zotero import.
- A browser extension that puts the assistant on publisher and search pages, fitting a reading workflow you already have.

90% rate a review on par with or better than the human peer review they have had.
Two in three rate it better. From 304 head-to-head ratings by researchers who had received peer review on the same paper. These are our own users, self-reported, which is worth knowing when you weigh them.
Depth
Why a thorough review takes the time it takes.
Most tools optimize for speed. Explore Science runs the engine we built to conduct original research autonomously, and points it at your manuscript: it reads recent literature in your field, checks every reference, and works through the paper the way a careful reviewer does.
The time is the method, not an overhead on it.

The engine
What actually reads your paper.
Three pieces of the architecture do the work behind every review.
Agents
Scientific agents that reason like the field.
Dozens of specialised agents work each review in parallel, each tuned to one dimension of analysis, spawning more when a section needs them.
Infrastructure
An in-house science stack.
Memory that holds your paper in context for the whole review, live verification of every citation, and novelty assessment. Built over years of autonomous science.
Both tools score a draft now
SciSpace's Peer Review agent asks three reviewer personas to rate a manuscript out of 10 on novelty, clarity, statistical rigor and impact, then merges them into a meta-review with a recommendation. That is a real pre-submission read, and it comes back in minutes. What it is not is a fixed rubric: personas produce opinions, and opinions from a fresh run are not directly comparable to the last one.
Calibre is the other design. One score out of 100, eight categories, the same weighting on every paper and every version, with a strengths-and-issues ledger naming what cost you the points. That is what makes a second pass worth doing: the number moves, and you can see which category moved it. For the submission decision itself, that comparability is the reason to pick Explore Science.
Checking your bibliography, not the literature's
SciSpace's Reference Checker validates DOIs, removes duplicates and enforces journal citation style, and its Citation Context Analyzer classifies how published papers cite each other: whether a citation supports, contrasts or critiques a study. Both are useful, and neither is pointed at your own reference list.
Explore Science reads your full text, then works reference by reference through live scholarly databases, flagging entries that do not resolve and, more importantly, entries that resolve to a paper which does not support the sentence citing it. A formatting error embarrasses you at review; an unsupported citation is what gets a paper retracted.
Common questions
What does SciSpace cost, and how does that compare?
SciSpace Premium is $12 a month billed annually ($20 monthly, 1,200 credits), but the tier carrying the heavier agent work is Advanced at $70 a month billed annually ($90 monthly, 10,000 credits). Explore Science is $49 for a single full-depth review with no subscription, or monthly plans from $99 with an allowance. At the comparable tier the gap is closer to 1.2x than to the headline 8x, so the real question is depth per run.
Can SciSpace compare two versions of my manuscript?
Yes, up to a point. Its Similarity Checker runs a direct document-to-document comparison with a diff-style view and tracks similarity change by source and section across revisions. What it does not do is rescore the manuscript on a fixed rubric each time, so you see text that moved rather than quality that moved. Explore Science reapplies the same eight categories to every version and shows the change in each.
Which one should I use for a systematic review?
SciSpace. It carries PRISMA flow diagrams, screening forms, deduplication, inter-rater agreement statistics and Zotero import, and Explore Science offers none of that. Explore Science is for the manuscript that comes out the other end.
Do I have to give up SciSpace to use Explore Science?
No, though you should not need both for the submission decision. Keep whatever you use for finding and reading papers, and bring the finished draft to Explore Science for the scored review, the reference verification and the version-to-version comparison. If one tool is going to tell you whether the paper is ready, that is the one it should be.
