## 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

## ResearchRabbit

ResearchRabbit is a free tool designed to make literature reviews faster and less overwhelming. Instead of dumping keyword results into a flat list, it turns a single paper you trust into an interactive map: you see related works, who cites whom, which authors are central, and where the field branches. The aim is to let your curiosity drive discovery rather than forcing you to guess the right search terms.

The engine is built on iterative chaining. It analyses a seed paper's bibliography, citations and co-authors to recommend related articles, and as you save and explore new papers the recommendations adjust to your interests. You can also connect your existing reference library so ResearchRabbit and your collection work together, making it easier to see how a literature review connects.

Scale is a core part of its pitch: ResearchRabbit reports being trusted by over one million researchers worldwide, with access to more than 320 million academic papers, and adoption across institutions ranging from Deakin and Monash to Cornell, Stanford and Harvard. It is operated by Litmap Limited and maintains a free sign-up flow.

**Pricing & Plans:** Free. ResearchRabbit is free to sign up and use for literature discovery and mapping, with no paid consumer plans advertised on its site. Recommendations run on publicly available scholarly metadata covering over 320 million papers.

- **Visual Paper Mapping:** Start from one paper and see how research connects through a visual map of related works, authors and citations.
- **Recommendation Engine:** The more you explore and select, the better it learns your interests, surfacing smarter and more relevant recommendations.
- **Literature Review Discovery:** Explore how your existing review connects and discover papers you may have missed, avoiding endless flat article lists.
- **Reference Manager Integration:** Bring your reference library and ResearchRabbit together so your collection and discovery work in one place.
- **Author & Topic Tracking:** Follow new works, emerging authors and trending topics as your research field evolves.

**Strengths:** Completely free to sign up and use; Visual, iterative maps beat long flat article lists for exploring a field; Learn-as-you-go recommendations improve with use; Integrates with your existing reference library

**Limitations:** It surfaces and maps papers rather than reading them for you—no automatic summarisation of full texts; No built-in full-text access; you still need your library or publisher access to read the papers; Deeper use benefits from connecting a reference manager, which adds a setup step; Some advanced collaboration and sharing features sit behind institutional or optional arrangements
