## 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

## ThesisAI

ThesisAI describes itself as "the AI research workspace" built around one promise: one prompt, fully cited. You import the papers you want to cite, then generate a structured academic draft where every claim carries an inline citation pointing back to a source you can verify.

The workflow is designed for long documents. It can cite up to 500 papers, produce drafts between 8 and 80 pages depending on your plan, and export as PDF, Word, LaTeX, or BibTeX. For researchers who work in LaTeX, it also exports to Overleaf so you can keep editing manually, and it connects with Zotero, Mendeley, and Semantic Scholar for references and paper discovery.

Beyond the web app, ThesisAI offers an MCP connector for Claude, ChatGPT, and Gemini, letting you summon cited drafts from the assistants you already use. Pricing is a simple per-month subscription metered by the number of documents you write.

**Pricing & Plans:** ThesisAI is a paid subscription. The Basic plan is $12/month and Pro is $16/month on monthly billing, with roughly 50% savings on annual billing; each includes a monthly allowance of documents and per-document page limits.

- **Cited drafts from your sources:** Import up to 500 papers and generate a first draft with inline citations that link to verifiable sources.
- **Long-form, multi-page output:** Write documents from 8 to 80 pages in a single prompt, depending on your plan.
- **PDF, Word, LaTeX, and BibTeX export:** Export finished documents as PDF, Word, LaTeX, or BibTeX, and push to Overleaf for manual editing.
- **Literature search and reference managers:** Search for additional papers automatically via Semantic Scholar and connect Zotero or Mendeley libraries.
- **MCP connector for major assistants:** Use the MCP connector to call ThesisAI from Claude, ChatGPT, or Gemini within your existing workflow.

**Strengths:** Every claim links to a verifiable source, reducing hallucinated references; Handles very long outputs (up to 80 pages) with up to 500 cited papers; Exports to LaTeX, Word, BibTeX, and Overleaf for real academic workflows; Integrates with Zotero, Mendeley, and Semantic Scholar, plus an MCP connector

**Limitations:** Paid only, with documents metered per plan rather than unlimited; Page limits per document depend on the plan tier; AI drafts still need expert review to meet academic standards
