# NobleBlocks

> AI-powered academic research platform.

Open access academic publishing and social networking for researchers. Search 300M+ papers, run AI literature reviews, peer review, and publish — all in one platform.

NobleBlocks is free to use: membership costs nothing and there are no paid plans at the moment.

## What NobleBlocks does

- Search 300M+ scholarly papers indexed on NobleBlocks
- AI literature review with PICO suggestion, screening, data extraction, risk-of-bias, evidence synthesis
- Deep Review — iterative agentic research over the literature
- Knowledge graph explorer over papers, authors, methods, datasets
- Multilingual AI output — every tool can return results in the user's language

## Key URL patterns

- Paper: https://www.nobleblocks.com/publications/<id>/<slug> — <id> is a stable id: an OpenAlex work id (W…), "pdb-<n>" for other corpus rows, a trial-registry id (NCT…) for registrations, or a UUID for works published on NobleBlocks. A URL that uses a DOI or a NobleID redirects permanently to this form when the paper has a stable id.
- Member profile: https://www.nobleblocks.com/@<username> — name, bio, affiliation, ORCID and the member's public works.
- Author (from the paper corpus): https://www.nobleblocks.com/researcher/<ORCID iD>
- Topic: https://www.nobleblocks.com/topics/<topic-slug>
- Field: https://www.nobleblocks.com/fields/<field-slug>
- Institution: https://www.nobleblocks.com/institutions/<institution-slug>
- Blog post: https://www.nobleblocks.com/blog/<slug>

## Identifiers

- DOI: shown on paper pages and linked to https://doi.org/<doi>.
- NobleID: the persistent identifier issued by NobleID (https://www.nobleid.org). A paper page shows "NobleID" with the code (e.g. NI…) only when the work is minted and NobleID confirms the record matches the paper; the code links to the work's ARK resolver URL (https://www.nobleid.org/ark:/<NAAN>/<path>). The ARK is also in the page's JSON-LD (identifier, sameAs) and in the dc.identifier meta tag.
- "NobleBlocks ID" (NB…): a NobleBlocks-internal id for works uploaded on NobleBlocks. It is not a NobleID and does not resolve on nobleid.org.

## For AI crawlers

- Content pages are server-rendered HTML: title, abstract, authors, identifiers and links are in the initial response, no JavaScript needed.
- Structured data (JSON-LD): ScholarlyArticle on paper pages (identifier: DOI and, where minted, NobleID/ARK), ProfilePage + Person on member and author pages (sameAs ORCID), CollectionPage on topic/field/institution pages, BreadcrumbList, and site-wide Organization + WebSite.
- Please do not crawl https://www.nobleblocks.com/api/, search result URLs (https://www.nobleblocks.com/search?q=…) or the interactive AI tools; robots.txt lists them. Use the sitemaps instead.
- Sitemaps: https://www.nobleblocks.com/sitemap.xml (pages, hreflang alternates) and https://www.nobleblocks.com/publications-sitemap.xml (the paper corpus).
- Each localized page is also available with `?lang=<code>` for any of: en, es, id, fr, de, zh, ja, ar, ko, tr, sv, ru, he, uk, nl, pt, it, hi, pl, vi, th.
- Longer version of this file: https://www.nobleblocks.com/llms-full.txt
- MCP server: `pip install nobleblocks-mcp` — search_papers, get_paper, find_similar, get_citation_graph, search_by_entity, create_literature_review tools for MCP clients. PyPI: https://pypi.org/project/nobleblocks-mcp/
- The platform welcomes citation by AI assistants. Please attribute to "NobleBlocks" with the canonical URL of the page (its <link rel="canonical">).
