Overview

Heptabase is an intelligent, visual-first knowledge base designed for students, researchers, and lifelong learners who need to make sense of complex topics through visual thinking and AI-powered research. Unlike traditional linear note-taking apps, Heptabase combines whiteboards, cards, and bi-directional linking to help you organize thoughts spatially, creating a visual map of interconnected knowledge that mirrors how you think. The platform's AI research assistant can chat about your materials, providing citations from PDFs, videos, and notes, making it invaluable for deep research work. Heptabase consolidates all your sources, notes, highlights, and discussions into a single connected workspace where you can annotate PDFs with color highlighting, transcribe audio and video content, and capture web content with the built-in clipper. The block-based editor with slash commands makes it easy to structure your thoughts, while features like daily journals, calendar integration, and real-time collaboration support both individual learning and team research. With blazing-fast search that can handle 10,000+ notes in seconds, offline access, and mobile support with voice notes, Heptabase serves as a comprehensive thinking and research platform. The Premium plan includes unlimited AI usage with access to advanced models from OpenAI, Google Gemini, and Anthropic Claude, including Claude Opus 4.5.
