## Casper AI

Casper AI is a browser extension aimed at people who spend their day absorbing information: analysts, strategists, policy watchers and business developers. Once installed in Chrome, it works on the page or PDF you are already looking at, using AI models to condense long articles, reports and papers into short summaries you can actually finish. The stated goal is to remove the reading bottleneck before a meeting, an exam or an investment decision.

The extension goes a step beyond plain summarization. It is designed to help you highlight the most important new insights, pull structure out of dense documents and turn what you learned into short notes you can share with teammates and stakeholders. Because it lives in the toolbar, the workflow is: open the source, summarize, and send the takeaway, without moving content into a separate tool.

Casper AI is distributed through the Chrome Web Store by its developer and offers in-app purchases on top of its free tier. It has a sizeable user base and a strong average rating, and it explicitly targets non-technical users who want AI assistance without building a prompt workflow themselves. Expect it to save time on reading-heavy tasks rather than to replace expert judgement on the documents themselves.

**Pricing & Plans:** Casper AI is listed as freemium in the Chrome Web Store with in-app purchases available alongside the free extension.

- **Web page summarization:** Condense long articles and pages into short summaries directly from the browser, without copying text into another app.
- **PDF summarization:** Work through reports and papers in PDF form and pull out the central points rather than reading cover to cover.
- **Insight highlighting:** Surfaces the most important new information in a document so you can focus attention where it matters.
- **Shareable notes:** Turn what you have read into concise notes you can forward to colleagues and stakeholders.
- **Chrome toolbar workflow:** Runs as a lightweight extension inside Chrome, so summarizing is one action away on any page you visit.

**Strengths:** Summarizes both web pages and PDFs from the same browser extension; 10,000+ users and a strong average rating in the Chrome Web Store; Designed for non-technical professionals, with no prompt engineering required; Share-oriented output makes it easy to brief teammates

**Limitations:** Requires Chrome, since it is delivered only as a browser extension; Summaries are only as good as the source document, so critical review still matters; Some capability sits behind in-app purchases rather than the free tier

## 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
