## SciSpace

SciSpace began as a typesetting and paper-formatting service called Typeset and has since grown into a broad AI research platform. Its core promise is that a researcher can move from finding a paper to understanding it to citing and writing about it without leaving one workspace. The platform indexes scholarly content from sources such as Google Scholar, PubMed and arXiv, and layers AI agents on top for reading, extracting data and synthesis.

The signature capability is conversational reading: you upload or open a PDF, then ask questions, highlight confusing sentences for plain-language explanation, or request structured summaries of methods, results and limitations. Around that sit task-specific tools — Literature Review, AI Writer, Paraphraser, Citation Generator, AI Detector, AI Humanizer, Extract Data and a Plagiarism Checker — plus a Chrome extension that adds the same assistant on top of publisher pages and a mobile app for reading on the go.

Access follows a freemium model: exploring and limited usage are free, while paid Premium, Advanced, Max and Enterprise plans raise model quality, credit limits and parallel agent capacity. The company is registered as PubGenius Inc. in Milpitas, California, and markets the product to individual researchers as well as universities and enterprises with SSO and admin controls.

**Pricing & Plans:** Freemium. A free tier with limited usage sits alongside paid Premium (~$12/month billed annually), Advanced (~$70/month) and Max (~$160/month) plans; monthly billing is higher. Enterprise pricing is custom. All plans advertise a 24-hour money-back guarantee, and annual billing carries a discount.

- **Chat with PDF:** Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
- **Literature Review and paper search:** Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
- **Writing, paraphrasing and citations:** An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
- **Extract Data and AI Detector:** Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.
- **Chrome extension and mobile app:** Use the same assistant on top of publisher sites and PDF pages via the browser extension, or read and query papers from the mobile app.

**Strengths:** Combines paper discovery, reading, writing and citation tools in one place instead of five separate subscriptions; Conversational explanations of difficult passages are genuinely useful for non-native English readers and cross-disciplinary work; Covers widely used scholarly sources such as Google Scholar, PubMed and arXiv; Free tier plus a Chrome extension make it easy to evaluate before paying

**Limitations:** Credit-based limits can be confusing, and heavy users report hitting caps on the cheaper plans; Model access varies by tier, so the cheapest paid plan does not get the strongest reasoning models; AI-generated reviews and paraphrases still need careful human checking for accuracy and citation integrity

## Thesify

Thesify targets the long, uncertain gap between finishing a manuscript and finding out what reviewers think of it. Reviewer reads a PDF or Word draft the way a peer reviewer would, then reports back on argument strength, methodology, evidence, structure and clarity, with each issue graded by severity so authors know what to fix first. Every review also ships with suggestions from an index of 200M+ genuine peer-reviewed articles, a journal matcher, topic and gap suggestions, a paper digest, and an exportable PDF feedback report that can be annotated or filed with a submission.

The second half of the product, Coauthor, is an AI writing workspace where agents search databases, read your uploaded PDFs and edit the document alongside you. Its distinguishing claim is provenance: the workspace tracks which text was human-written and which was AI-generated, and it keeps version history with rollback, supports live co-author collaboration, and compiles LaTeX into export-ready PDFs. Thesify positions itself explicitly against general-purpose chatbots by emphasizing that it does not invent citations, that its cited sources are drawn from a live academic index, and that uploaded documents are never used to train models.

Delivery is fully browser-based with nothing to install, and the team sells to individuals, departments and institutions. Credits are non-expiring, which matters for researchers working in bursts around submission deadlines, and institutional licensing is offered with GDPR and FERPA-aligned deployment.

**Pricing & Plans:** Freemium-style access via a 7-day free trial on Coauthor; Reviewer is paid. One-off review credits cost €14.95 for a single review or €39.95 for three. Reviewer subscriptions run €24.95/month (3 reviews plus AI chat) or €149.95/year, which brings the per-review price to roughly €4.17. Coauthor costs €24.95/month or €149.95/year. All prices in EUR, VAT included; one-time credits never expire.

- **Manuscript pre-submission review:** Upload a draft as PDF or Word and get a full reviewer-style report covering argument, methodology, evidence, structure and clarity, with findings graded by severity.
- **Real-reference suggestions:** Relevant articles are matched from an index of 200M+ peer-reviewed papers, and the platform explicitly avoids fabricating citations that do not exist.
- **Journal recommender:** Get a ranked shortlist of venues matched to your manuscript, with fit, impact factor and selectivity detail to help you choose where to submit.
- **Coauthor AI writing workspace:** Agents search sources, read your PDFs and edit your document, with automatic version history, live co-author collaboration and LaTeX-to-PDF compilation.
- **AI vs human provenance tracking:** Every contribution is attributed so supervisors and co-authors can see exactly which parts of a document were written by a person and which by the AI.

**Strengths:** Feedback arrives in minutes rather than the two to four weeks a human peer editor typically needs; Per-review cost drops to roughly €4.17 on the yearly plan, far below €80–900 for proofreaders and editing agencies; Citation suggestions come from a real academic index, addressing the hallucinated-reference problem of general chatbots; Review credits never expire and there is nothing to install — it runs entirely in the browser

**Limitations:** Reviewer has no free tier and no free trial, so you must pay before you can judge the quality of feedback; The tool is built for theses, dissertations and scientific papers; students needing help with general essays may find the academic rubric overkill; AI feedback cannot replace a subject-matter expert's judgement on novel methodology
