## 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

## Heptabase

Heptabase is designed for people who want to understand material rather than merely collect it. At its core is a whiteboard where you break any source into cards — by hand or with AI — and then read deeper by following each citation back to its origin. Supported sources include PDFs, web pages, YouTube videos, podcasts, Readwise and Zotero, so research from different places lands in a single visual space. Nested databases, tags and properties then give that material a structure you can reshape as your understanding changes.

AI features are framed as learning aids rather than answer machines. An AI Tutor turns a goal into a personalised course, and AI assist helps process readings and organise cards on the board. For those who already work inside other AI tools, Heptabase exposes your knowledge base through Claude Code, ChatGPT, Codex and Grok Bot, plus a plugin, MCP server and CLI, so notes can be queried from the assistant you already use.

The practical basics are covered too: a block editor with daily journals, bi-directional links and web clipper; PDF highlight and annotation; offline access; mobile apps; and real-time collaboration for co-annotating boards. Heptabase offers a 7-day trial across mobile and desktop and positions itself as a long-term knowledge home rather than a quick note dump.

**Pricing & Plans:** Heptabase offers a 7-day free trial, with paid subscription plans published on its pricing page covering individual use. Refer to the pricing page itself for current figures.

- **Whiteboards for breaking down sources:** Split PDFs, web pages, YouTube videos, podcasts and Readwise or Zotero items into cards and read deeper through every citation.
- **AI Tutor and AI-assisted reading:** Turn any goal into a personalised course and process readings with AI help before arranging ideas on the board.
- **Nested databases, tags and properties:** Give your knowledge a structure that can be reworked as you learn, using nested tags and properties rather than flat folders.
- **Works with the AI tools you already use:** Query your knowledge base from Claude Code, ChatGPT, Codex or Grok Bot through the plugin, MCP server and CLI.
- **PDF annotation, offline access and collaboration:** Highlight and annotate PDFs, work offline, sync in real time and co-annotate boards with other people on desktop and mobile.

**Strengths:** Whiteboard-plus-database model suits understanding, not just storage; Ingests PDFs, web pages, YouTube, podcasts, Readwise and Zotero; Integrates with Claude Code, ChatGPT, Codex and Grok through plugin, MCP and CLI; Offline access, mobile apps and real-time collaboration included

**Limitations:** Whiteboard metaphor takes time to learn if you are used to linear note apps; Only a 7-day trial before committing to a paid plan; Heavy canvases can become unwieldy without disciplined card naming
