## 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

## Unriddle (Anara)

Unriddle is best known as an AI research assistant for reading, organising, and writing scientific documents — and the product now lives on under the name Anara. Visiting the old unriddle.ai address brings you to the current Anara workspace, which keeps the same core proposition: keep a persistent library of your papers and data, search the academic literature, and write with claims that trace back to a source rather than to an unattributed model summary.

The workflow is built around a few concrete jobs. First, search: Anara queries over 300 million papers, supports filters for journal, year, and citation counts, and surfaces PubMed and clinical trial registry results, so you can screen candidates against your inclusion criteria and save the ones you need. Second, build: upload PDFs, notes, slides, and recordings (with OCR for scanned documents on the Pro plan) and the system keeps them indexed, with Zotero or Mendeley sync and metadata filled in automatically. Third, ask: query one paper, a folder, or your whole library, and receive answers that link to the exact passage — open-access full text where available — so verification takes one click.

Beyond answering questions, Anara handles the research busywork that general chat tools ignore. It can turn a folder into a cited extraction table with one row per paper and one column per question, exporting to CSV or Excel. It can draft in notes with citations suggested from your library and export to Word, LaTeX, or BibTeX in a chosen style. There is also an API and MCP server for programmatic search and citation resolution. Pricing runs from a free tier with limited usage to Pro at roughly $20 per seat per month (billed yearly), with Max and enterprise options above that. Full details are on the official pricing page.

**Pricing & Plans:** Freemium with paid seats. Free includes limited AI usage, ~20 MB / 120 pages per upload, and Zotero/Mendeley connectors. Plus is about $10/seat/month billed yearly, Pro about $20/seat/month, and Max tiers about $100 and $200/seat/month (monthly billing costs more). Enterprise pricing is custom — contact sales.

- **Search across 300M+ papers:** Search more than 300 million papers across medicine, physics, and other fields, filter by journal, year, or citation count, and save relevant results to your library with one click.
- **Persistent research library:** Upload papers, notes, slides, and recordings; Anara indexes them all and lets you ask questions scoped to a single file, a folder, or your entire collection.
- **Passage-level citations:** Every answer points to the exact passage it came from, verifiable in one click — the core differentiator versus general chat assistants.
- **Cited data extraction tables:** Turn a folder of papers into a structured table with one row per paper and one column per question, with every cell cited, then export to CSV or Excel.
- **Academic writing and export:** Draft in notes with citations suggested from your own library, then export to Word, LaTeX, or BibTeX in the citation style your journal requires.

**Strengths:** Every answer is tied to the exact source passage, so claims are verifiable in one click; Searches 300M+ academic papers plus science databases like PubMed and ClinicalTrials.gov; Works across your own uploaded library, a folder, a single file, or the open web; Cited extraction tables and Word/LaTeX/BibTeX export cut down formatting drudgery

**Limitations:** Free tier is capped on AI usage and upload size (20 MB / ~120 pages per upload); Credit and usage allowances can add up for heavy, library-wide queries on paid seats; The rebrand from Unriddle to Anara means some links, tutorials, and community references are out of date; Best features (model choice, OCR, Deep Search, no-limit uploads) are locked to higher tiers
