## 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

## Fenn

Fenn is a private AI search layer built specifically for macOS. Instead of uploading your documents to a cloud service, Fenn builds a local index of your Mac's contents, including files you might otherwise lose track of: PDFs, Word and Pages documents, spreadsheets, design files from Figma or Adobe, photos, videos, audio recordings, notes, and emails. Because indexing and AI processing happen on-device, you can search confidential material without sending it to a third-party model provider.

Beyond basic filename search, Fenn understands content. You can ask natural-language questions such as "find the video where the presenter talked about pricing" and get the exact timestamp. It transcribes audio and video, extracts text from scanned documents, supports face recognition and content-similarity search, and offers screen memory so moments that were never saved as files can still be recalled. Fenn also acts as a lightweight productivity agent: it auto-organizes folders, finds and removes duplicates, renames files based on their content, converts documents, images, invoices and videos into structured CSV, and can anonymize sensitive details before you share a file with an external chatbot.

Fenn comes from a small team and is sold as a downloadable app for Apple Silicon Macs. Licensing is straightforward: a flexible annual plan, a one-time lifetime license, and a Teams tier, all including the same feature set, continuous updates, and a companion iPhone app. The central promise is simple — the power of AI search without ever handing your data over.

**Pricing & Plans:** Fenn offers a Flex plan at $9/month billed annually, a Lifetime plan at $249 paid once, and a Teams plan at $999. A free trial appears to be available; check the site for current terms.

- **On-device private indexing:** Files are indexed and processed entirely on your Mac, so your documents, recordings, and screen memory never upload to a cloud AI provider and search keeps working offline.
- **Search inside 120+ file types:** Query the contents of PDFs, Office and Apple documents, design files, code, images, audio, and video, returning the exact page, line, or timestamp instead of just a filename.
- **Screen memory and recall:** Recall meetings, chats, dashboards, and shared screens that were never saved as files, then jump straight back to the moment you need.
- **AI file organization and renaming:** Auto-organize folders with live criteria, find and remove duplicate files, rename files based on their content, and convert documents, invoices, images and videos into structured CSV.
- **Private chat with your files:** Ask questions, summarize, compare versions, and extract information across your library, with citations back to the source — all processed locally.

**Strengths:** All AI processing happens locally, so sensitive files never leave the Mac; Understands content inside 120+ file types, including audio, video, and scanned PDFs; Unusual capabilities like screen-memory recall, CSV extraction, and content-based renaming; One-time lifetime license option for people who dislike subscriptions

**Limitations:** Limited to macOS on Apple Silicon, with no Windows or Linux version; Local indexing of large media libraries can consume significant disk space and CPU time; Pricing is on the premium side compared with simple filename search utilities
