AI research platform for reading, understanding and writing scientific papers
Open or upload a paper and ask questions, get plain-language explanations of highlighted passages, and pull out methods, results and limitations conversationally.
Search a large scholarly index spanning Google Scholar, PubMed and arXiv, then generate structured literature reviews and related-work sections from what you find.
An AI Writer for drafts, a paraphraser for academic tone, and a citation generator that formats references in popular styles.
Turn tables and results in a paper into structured data, and check whether a manuscript reads as AI-generated with a built-in detector.

The memory engine that lets any AI agent learn and remember across sessions
A dedicated learner model extracts, merges, infers and forgets facts, storing each learning in a vector-graph database that understands entities, sources and time.
Learnings are injected into the model's context in real time via hooks, so agents recall relevant information without stuffing full histories into the prompt.
Memory lives outside any single model provider, so it carries across models and harnesses and is delivered through the API, plugins and MCP.
Mandatory memory is only billed once: repeated or unchanged content is not charged again, and the same rates apply on every plan.

The AI workspace where teams and agents get work done together

Free / Open-sourceProvides a massive free index of scholarly literature with citation graphs, but lacks built-in interactive paper reading assistants.


Provides evidence-based answers extracted directly from peer-reviewed papers, though less of an all-in-one reading workspace.

Enterprise AI grounded in your company's own knowledge
Stronger automated data extraction and systematic review synthesis, but less focused on interactive PDF annotation than SciSpace.
SpecialistFocuses heavily on assisted academic drafting and autocomplete, whereas SciSpace centers more on reading and analysis.
Excels at tracking citation contexts and how papers cite each other, but has less robust general PDF chat features.

AI-powered knowledge base that turns documents into fast answers
Streamlines literature searches and reference management like SciSpace, but with a distinct citation workflow.
Interactive knowledge that makes support answers faster and self-service actually work
An AI notes app that organizes your knowledge for you
