## 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

## SummifyYT (Summarize YouTube Comments)

SummifyYT is a browser extension for people who want to understand how an audience reacted to a video without manually reading through a comment thread that may run to thousands of entries. It embeds directly into the YouTube watch page, adds a summary button to the interface, and returns a short digest of the comment section covering the points viewers repeat, praise, or push back on.

Unlike many summarizers that charge for API usage, SummifyYT leans on the ChatGPT session already active in your browser. That design keeps the tool free, but it also means you need to be logged in to ChatGPT for it to work at all. The extension exposes a small settings panel where you can switch on GPT-4, toggle auto-start so a summary is generated the moment a watch page loads, and pick the language you want the summary written in.

The extension has been on the Chrome Web Store for years and is small (roughly 140 KB). Development has slowed — the last published update dates to April 2023 — and the rating sits at a modest 2.8 out of 5. It remains a functional, free option for a quick read on a comment section, especially for creators and researchers triaging audience feedback at scale.

**Pricing & Plans:** Completely free. The extension itself costs nothing and has no in-app purchases; it reuses your existing ChatGPT account, so any costs are whatever your ChatGPT plan already covers.

- **Comment section summarization:** Turns a long YouTube comment thread into a short, readable digest of the main points viewers are making.
- **Embedded on the watch page:** Adds its controls directly to YouTube's UI, so you can trigger a summary without leaving the video you are watching.
- **Language selection:** Lets you choose which language the generated summary is written in, useful for multi-language audiences.
- **GPT-4 toggle and auto-start:** An optional setting switches summarization to GPT-4, and another can fire the summary automatically whenever a watch page loads.
- **Uses your ChatGPT session:** No separate API key or subscription — the extension works through the ChatGPT login you already have in the browser.

**Strengths:** Free to use with no subscription or API key; Lives inside YouTube, so no copy-pasting links between tools; Adjustable summary language and a GPT-4 option; Very small download size and quick to install

**Limitations:** Requires you to be signed in to ChatGPT, so it is unusable without an account; Last updated in April 2023 and receives infrequent maintenance; Modest user rating (2.8/5) suggests inconsistent results for some users
