Features
Everything Littreview does, in one place — no owned corpus, everything either live from OpenAlex/Semantic Scholar/Crossref or your own contributed content.
Federated search
One query, merged and de-duplicated across OpenAlex, Semantic Scholar, and Crossref, with automatic British/American spelling-variant expansion (e.g. "tumour" also finds "tumor").
Live citation graph
Seed a map with one paper, expand its references and citing papers with a click, clustered into groups by discipline/field.
Citation gaps
Finds papers cited by two or more papers already on your map that aren't in the map yet — the graph-native equivalent of a citation gap-check.
List & timeline views
The same map data, sorted by citation count or laid out chronologically — filterable by year, minimum citations, discipline, and abstract availability.
Compare search
Run one query side-by-side, split into columns by source (OpenAlex/Semantic Scholar/Crossref) or by discipline/field, each with its own summary card.
Abstract-only summaries
A short extractive summary generated from the abstract by our own local pipeline (LexRank) — never a third-party model, never the full paper text.
Search and dictate by voice
Speak a search query straight into the search box — runs entirely in your browser, nothing sent to a server to transcribe it.
Saved maps
Save a citation map to your account and come back to it later.
Notes & drafting
Write in a full-page document editor, pull in citations directly from search results or citation-gap cards (multi-select "add to draft"), and format them in the citation style you need.
OCR paper upload
Upload a scan or preprint not well-indexed by the live sources — it's OCR'd, its references are extracted, and it's added to your map as a node.
Audio transcription
Upload a lecture, interview, or voice memo — transcribed on our own server (never a third party) and saved straight into a new draft.
BibTeX import
Upload a .bib file and its entries are added straight into your most recent draft as citations.
Zotero
Connect your Zotero library with a personal API key — push a paper straight into it from your map, or pull your library in as seed candidates.
Bring your own AI
Connect your own OpenAI-compatible model endpoint to ask questions about an uploaded paper or a paper on your map — answers are grounding-checked against the source text before being shown.
AI-generated-text detection
Nine independent statistical/stylometric signals plus a classifier model, run on an uploaded document — advisory only, explained in plain language, never a single blended "score."
Citation verification
Checks each reference in an uploaded document against OpenAlex/Semantic Scholar/Crossref, with a web-search fallback for anything not found in those indexes — flags citations that may be fabricated or just hard to find.
Profile
Your account home — saved maps, uploads, and account details in one place.
Superadmin
Separate, 2FA-protected credential for site administration — entirely independent of regular accounts.
