Instead of publishing a plain HTML listing like a traditional directory, CitableHub turns each submission into structured, schema-rich profile data — JSON-LD and Schema.org markup — that AI systems such as ChatGPT, Perplexity, Claude and Gemini can parse, trust and cite. The directory reports 899+ projects listed and more than 25,000 AI crawler reads to date. Listing a project is designed to take about ten minutes. You submit your details, the platform uses AI to autofill the harder parts, and you receive an AI-citable profile plus a launch kit: a personalised checklist of directories and platforms to submit to, with ready-to-paste copy, links and UTM tags. Each profile carries a Citability Score rated across five dimensions, so there is a visible signal of how citable a project currently is. Pricing is deliberately low-friction. The free plan lists up to 2 projects and includes the Discovery AI engine, the promotion checklist and full analytics. Citation Radar unlocks room for up to 6 projects, while GQI Boosts push products into the Billboard spotlight — and notably, boosted items are the only ones placed there. Creators can also earn a flat 20% referral fee by recommending CitableHub to their audience. **Pricing & Plans:** CitableHub is freemium: the free plan lists up to 2 projects and includes the Discovery AI engine, your AI-citable profile, the promotion checklist and full analytics, with no credit card required. Citation Radar unlocks listings for up to 6 projects, and GQI Boosts are a paid option that places a product in the Billboard spotlight.

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 [Profile (Markdown)](https://openaitools.app/tool/scispace.md) ## Frequently Asked Questions ### How do CitableHub and SciSpace compare in monthly traffic?
