An intelligent visual knowledge base for people who want to understand and create knowledge, not just collect it.

Heptabase is a visual knowledge base for reading, research, and writing. It uses whiteboards, nested databases, bi-directional links, block editing, and daily journals to organize ideas and turn sources into connected notes.
It supports PDFs, web pages, YouTube videos, podcasts, Readwise, and Zotero. You can break sources into cards by hand or with AI, read citations in context, clip from the web, highlight PDFs, and collaborate in real time.
Heptabase also includes an AI tutor for learning, offline access, mobile apps, and workflow integrations for Claude Code, ChatGPT, Codex, and Grok Bot. A CLI and MCP mention appears in the product text, but no public API is stated.
