## 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

## Karla (now Prism)

Karla started life as an AI writing assistant aimed squarely at journalists. The idea was to take the messy inputs of reporting — interview notes, official documents, transcripts, press releases — and use a large language model to help shape them into a structured article draft, so that writers could focus on judgment and editing rather than typing out background material.

The product has since moved on. Visitors to the original getkarla.com address now see the message 'Karla is now Prism', followed by a redirect to PrismRun.ai. The company says it changed the name because it now focuses on building a protocol and platform to define and execute complex processes and actions with AI — a broader ambition than a single-purpose newsroom editor.

If what you wanted was the original journalism tool, the site directs you to Newsrun.ai, a newsletter and information services product that uses Prism under the hood. So the Karla brand itself is retired, but the underlying AI writing and process technology continues to be developed and sold under the Prism name.

**Pricing & Plans:** Karla was offered on a freemium basis before the rebrand. Pricing for the successor product, Prism, is not published on the redirect page, so current plans and costs should be confirmed on the PrismRun.ai site directly.

- **Turn raw source material into articles:** Paste notes, documents, transcripts or press material and let the AI reshape it into a coherent article draft.
- **Structured writing workflow:** An editor built around the way newsrooms work, so structure and flow matter as much as speed of drafting.
- **LLM-powered drafting:** The engine underneath was built as a large-language-model-based writing assistant rather than a simple summariser or rewriter.
- **Now evolved into the Prism platform:** The project has evolved into Prism, a platform for defining and executing complex AI processes, with journalism features maintained at Newsrun.ai.
- **Made for journalism and editorial teams:** It was designed for professionals who handle constant input from many sources and need to turn it into published output quickly.

**Strengths:** Purpose-built for newsroom and editorial workflows; LLM-based drafting that goes beyond simple summarisation; Turns scattered source material into a structured starting draft; Technology lives on and is actively developed under the Prism brand

**Limitations:** The Karla name no longer exists — the product is now branded Prism, which can confuse people looking for the original tool; Journalism-specific workflow features have been split off to a separate product, Newsrun.ai; New target audience (developers and process designers) means some original newsroom-oriented features may not map to every user's needs
