## 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

## Sankofa

Sankofa is a Chrome extension published by Vectara, the company behind a generative-AI search API. Its premise is simple: your browser forgets almost everything, so Sankofa quietly remembers the content of the sites you visit and makes that content searchable again. To do that it indexes page text into a corpus inside your own Vectara account.

Setup is a one-time process. You sign up for a free Vectara account, create a corpus, and enter the relevant details into Sankofa. From then on you can index a single page on demand, index just a block of text, or instruct the extension to automatically index every page you visit after a delay you choose. Because the corpus is yours, you keep control over what gets stored.

Once content is indexed, Sankofa turns your history into a small personal knowledge base. You can ask questions in a ChatGPT-like chat and receive answers built from the pages you have read, search for pages on a topic rather than by exact title, or surface pages similar to the one you are currently on. It is especially handy for research sessions where you read dozens of tabs and later need to recall a specific fact.

Because it depends on your own Vectara corpus, the useful capacity and speed follow your Vectara plan, and the extension itself is free. It is listed as version 0.0.2 with a February 2024 update, and the store reports web-history and website-content permissions, so it is best suited to users who are comfortable routing page text through a third-party indexing service.

**Pricing & Plans:** The Sankofa extension is free. It requires a separately created Vectara account, which offers a free tier; usage beyond that tier is governed by Vectara's own pricing.

- **AI research over your history:** Ask ChatGPT-style questions and get answers grounded in the pages you actually read, using Vectara's generative search.
- **Remembered page content:** The extension has seen the content of pages you visited, then lets you search those pages by topic instead of by URL.
- **Find similar pages:** Point Sankofa at your current page and find other pages in your indexed history that cover similar topics.
- **Flexible indexing modes:** Index a page on demand, index only selected text, or let Sankofa automatically index pages after a set delay.
- **Powered by your Vectara account:** Connect your own free Vectara account and create a corpus, so all indexed data is stored under your control.

**Strengths:** Turns ordinary browsing history into a searchable AI knowledge base; Answers are grounded in pages you actually read, not the open web; Works with your own Vectara corpus, so you control the data store; Automatic indexing means research pages save themselves

**Limitations:** Requires a separate Vectara account and manual corpus setup before it is useful; Indexing relies on your Vectara quota, so heavy browsing can hit limits; Only works meaningfully with a free-but-limited Vectara corpus; Small user base with no update since early 2024
