## Consensus

Consensus works like a scholarly search engine supercharged by AI. Instead of returning a flat list of PDFs, you ask a natural-language research question and Consensus extracts claims from relevant papers, then shows you what the studies actually find. A Consensus Meter summarizes the weight of evidence for yes/no questions, so you can see at a glance whether scientists largely agree, disagree, or remain divided.

The platform indexes hundreds of millions of peer-reviewed papers spanning medicine, biology, psychology, economics and more. Answers link straight back to the source studies, and you can filter by study design, journal quality, sample size and publication year to separate stronger evidence from weaker signals. Features like Deep Search, Topic Synthesis and Skills let researchers build a working knowledge base over time rather than starting from scratch on every query.

Consensus is designed for researchers, clinicians, students and analysts who need trustworthy signals from the scientific record without drowning in irrelevant results. A free tier gives limited AI-powered searches each month, while paid plans unlock unlimited use, advanced filters and deeper synthesis.

**Pricing & Plans:** Freemium. A free tier offers a limited number of AI-powered searches per month; paid individual plans unlock unlimited searches and advanced research features, with discounted student pricing and team/enterprise options.

- **Evidence-grounded answers:** Ask a research question in plain language and get answers synthesized from peer-reviewed studies, with each claim linked to its source paper.
- **Consensus Meter:** A visual summary shows how the scientific literature leans on a yes/no question, indicating agreement, disagreement or mixed evidence.
- **Powerful filters:** Narrow results by study design, sample size, journal quality, publication year and more to prioritize high-quality evidence.
- **Topic synthesis and Deep Search:** Aggregate findings across many studies into structured summaries that map what is known and where the gaps are.
- **Research workspace:** Save papers, organize sources and build a persistent knowledge base for literature reviews and ongoing projects.

**Strengths:** Answers cite real peer-reviewed papers, so claims are verifiable; Consensus Meter makes it easy to gauge scientific agreement at a glance; Rich filters help separate high-quality evidence from weaker studies; Fast, clean interface designed around research workflows

**Limitations:** Free tier caps the number of AI-assisted searches per month; Coverage is strongest for STEM and health fields, lighter for some humanities topics; It guides you toward sources but is not a substitute for reading full papers

## Otio

Otio describes itself as your personal librarian for the web. It comes in two cooperating parts: a Chrome extension that lives in the bottom-right of every page, and a web workspace at otio.ai where the saved material is actually put to work. The extension has around 4.5 stars from a modest but real user base, and the developer is Frontdoor Labs Ltd in London.

The value proposition is aimed squarely at research that spans weeks or months. Rather than losing your sources when a chat session resets, Otio keeps a permanent, searchable library organised by project — a thesis separate from client work, a market analysis that grows as new data arrives. Upload 60 papers one month and add 30 client documents the next, then question all 90 sources together. Saving is designed to be frictionless: a save button appears in the corner of pages, with native-style placement on YouTube, X, Substack and Medium, and a keyboard shortcut for everything else.

On the workspace side, Otio reads and indexes PDFs, articles, video transcripts, podcasts, tweets, spreadsheets and scanned documents via OCR, then supports chat and dual-model chat, summarisation, note-taking, deep research and visualisation. The most-repeated claim is citation quality: answers point back to the exact page and passage so references can be checked rather than trusted blindly. Otio publishes a free entry tier and markets itself against both session-based chatbots and source-capped notebooks, and its marketing cites more than 200,000 professionals and researchers across 74 languages.

**Pricing & Plans:** Freemium: the Chrome extension can be installed free and the Otio workspace offers a free starting tier ('Get started free') alongside paid plans that raise usage limits, in line with the subscription model typical of research workspaces. Check otio.ai/pricing for current tiers and allowances.

- **One-click saving from anywhere:** A floating save button plus Cmd/Ctrl+Shift+S captures pages, PDFs, videos and tweets, with native-style buttons injected on YouTube, X, Substack and Medium.
- **Spotlight-style library search:** Cmd/Ctrl+Shift+K searches every saved link, PDF, tweet and video without leaving the page; Shift+R surfaces similar items in your library.
- **Chat across sources with verified citations:** Ask questions across an entire project and get answers that point to the exact page and passage, so you can verify in one click.
- **Multi-model support in one workspace:** Compare or switch between leading AI models with dual chat instead of stacking several subscriptions.
- **Automatic tagging and summarisation:** Otio organises and summarises new saves on arrival, so the reading queue stays usable as it grows.

**Strengths:** Persistent source library that doesn't reset between sessions or cap the number of sources; Citations resolve to exact pages and passages, making verification practical; One-click capture works across articles, PDFs, video, podcasts and social posts; Multiple AI models available in one workspace instead of several subscriptions
