## 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

## Heuristica

Heuristica is built around the idea that one source should become many study formats. Instead of watching a lecture twice or highlighting a PDF by hand, you drop in a link or file and the platform generates a connected concept map first, then lets you expand any node into flashcards, quizzes, study notes, or an essay outline. Concept maps keep the relationships between ideas visible, which many learners find more useful than linear notes for complex or interdisciplinary topics.

The platform is particularly strong on importing real sources. It accepts PDFs, YouTube videos, podcast episodes, articles, and academic sources such as PubMed and arXiv, generating transcripts, summaries, and key takeaways. From there, flashcard decks use spaced repetition for active recall and quizzes come in multiple formats with sharing options for classmates and colleagues. A multi-model AI chat lets you pick between ChatGPT, Claude, Gemini, and others, apply custom instructions or saved prompts, and then convert a conversation into flashcards or notes.

Heuristica is positioned for students, teachers, researchers, and lifelong learners, and reports more than 75,000 users. It is a freemium product with free tools and a paid plan that unlocks higher limits; the company says it is made in Switzerland. Check the pricing page for current tiers and limits.

**Pricing & Plans:** Freemium — free tools and a free starting tier, plus a paid plan with higher limits. Check the pricing page for current tiers.

- **AI concept and mind maps:** Build a visual canvas of connected ideas from a prompt, document, video, or podcast, then branch topics out as far as you need.
- **Flashcards and quizzes:** Convert notes, PDFs, videos, or a concept map into flashcards with spaced repetition and multi-format quizzes with instant feedback.
- **Multi-source import:** Bring in PDFs, YouTube videos, podcasts, websites, and academic sources like PubMed and arXiv, with transcripts and summaries generated automatically.
- **Multi-model AI chat:** Chat with models such as ChatGPT, Claude, and Gemini, apply custom instructions or saved prompts, and turn answers into study materials.
- **Study notes and summaries:** Produce structured study notes and study guides from lectures, videos, and long documents so review time is shorter and better organized.

**Strengths:** Single platform covering mapping, flashcards, quizzes, notes, and chat; Strong source import: PDFs, YouTube, podcasts, and academic databases; Concept maps feed directly into other study formats instead of being a dead end; Multiple LLMs selectable in one interface, with saved prompts and custom instructions

**Limitations:** Feature breadth can feel overwhelming at first; Quality of maps, quizzes, and notes depends on the source material provided; Advanced usage requires a paid plan
