## NNScholar

NNScholar organizes research as a project rather than a series of one-off chats. You start with a topic, DOI, PMID, arXiv ID, or a free-form research question, and the literature search turns that into a ranked set of sources that you can save into a persistent project library. From there the app becomes a reading environment: you can chat with individual PDFs, translate them, annotate them, and ask questions whose answers stay anchored to the specific paper in context.

The distinguishing piece is its evidence system. Instead of producing fluent paragraphs that may or may not be grounded, NNScholar maintains an evidence board that ties claims, sources, decisions, risks, and follow-up actions together, and lets you trace citations forward and backward from seed literature. Research agents and reusable 'academic skills' handle repeatable tasks such as data extraction, screening, synthesis, and verification, so the same workflow can be applied across a large batch of papers.

When the reading and evidence work is done, the same workspace carries you into writing: outlines, drafts, figures, and submission materials are assembled with nearby sources still visible. NNScholar also connects to academic infrastructure through MCP, including Zotero, OpenAlex, PubMed, arXiv, Crossref, and ClinicalTrials.gov, and supports multiple LLM backends as well as custom OpenAI- or Claude-compatible endpoints. Pricing runs on a single visible credits balance, with free starter credits and rolling monthly plans.

**Pricing & Plans:** Freemium with a single credits balance. New users get free credits, and there is a one-time intro month offer alongside rolling 40-day Lite, Pro, Plus, and Max plans that grant increasing credit allowances. Credits are consumed by AI screening, chat, PDF reading and translation, agents, and skills.

- **AI literature search:** Launch a literature review from a topic, DOI, PMID, arXiv ID, or research question, inspect titles and abstracts, and save the useful hits into a shared project library.
- **PDF reading and translation:** Chat with a PDF, translate it, annotate passages, and ask questions that stay scoped to the academic paper you are reading.
- **Evidence board and citation tracing:** Connect claims, sources, decisions, and open questions in one board, then follow references and related work forward and backward from your seed literature.
- **Research agents and academic skills:** Reusable agents and skills handle routine tasks such as screening, data extraction, synthesis, and source verification, which makes batch review work practical.
- **Broad model and tool connectivity:** Connect academic databases and reference tools through MCP, including Zotero, OpenAlex, PubMed, arXiv, and Crossref, and choose among multiple models or bring your own API key.

**Strengths:** Keeps sources, notes, and evidence in one persistent project instead of scattered chat threads; Evidence board and citation tracing make it easier to check whether a claim is actually supported; MCP integrations with Zotero, PubMed, arXiv, and similar tools fit real academic workflows; Flexible model choice, including bring-your-own API keys through OpenAI- or Claude-compatible endpoints

**Limitations:** Credit-based pricing means heavy agent use can be hard to predict up front; Desktop-app-first design is less convenient for purely browser-based workflows; Feature depth has a learning curve, so casual users may only touch a fraction of it

## OpenRead

OpenRead is built for people who read a lot of research and need to make sense of it quickly. It indexes a very large body of scholarly literature — the site advertises access to over 300 million papers, with fresh papers arriving from thousands of journals — and layers AI on top so you can search by meaning, not just keywords. You can upload your own PDFs alongside the public corpus and build a personal research space.

Beyond simple summarization, OpenRead focuses on synthesis. Paper Compare highlights where studies agree and where they contradict each other, Paper Q&A lets you interrogate a document, and a related-paper graph shows how ideas connect across the literature. An Espresso mode and note-taking tools support fast skimming and capture, while chat access to top-tier AI models handles diagram drawing, image editing and homework-style questions — the platform positions itself as picking the best model for each task.

The service has a free tier and a Pro subscription, and it also runs a program that pays experts for contributing knowledge. It is aimed at researchers, analysts and students working across disciplines, including market research, competitive intelligence and policy analysis.

**Pricing & Plans:** OpenRead uses a freemium model: a free tier for core search and reading, plus a Pro subscription that unlocks higher limits and advanced AI features. Contact the team for institutional or enterprise arrangements.

- **Semantic paper search:** Search a corpus of hundreds of millions of papers by meaning, with new content indexed continuously from thousands of journals.
- **Paper Q&A and Compare:** Ask questions of any paper and place multiple studies side by side to spot agreements, contradictions and the bigger picture.
- **Related paper graph:** A visual graph maps how papers and concepts connect, helping you find adjacent work you would otherwise miss.
- **Uploads, notes and workspace:** Upload your own PDFs, capture reading notes, and organize everything in a single research workspace.
- **Multi-model AI tools:** Access top-tier models for chat, diagram drawing and image editing, with new models added as they ship.

**Strengths:** Very large indexed corpus with continuously refreshed papers; Synthesis tools (Compare, Graph) go beyond basic summarization; Combines external literature search with your own uploads; Multi-model chat for tasks like diagrams and images

**Limitations:** Advanced features and higher limits sit behind the Pro plan; A very broad feature set can take time to learn; Multi-model chat is a general assistant aid rather than a peer-review tool; No indication of full offline or self-hosted use
