It is less suited for users seeking a lightweight task list or an entirely free note-taking application. ## What it is Heptabase is an intelligent, visual workspace designed for deep research, study, and knowledge organization. It pairs an infinite whiteboard canvas with structured, block-based card notes and bi-directional linking, allowing users to map concepts spatially without losing atomic text structure. The platform integrates source handling directly into the workflow, supporting PDF annotation, optical character recognition (OCR), and YouTube transcript extraction alongside daily journals and a web clipper. Built-in integrations connect with external reference tools such as Readwise and Zotero, while the Heptabase CLI supports interaction with developer tools like Claude Code and Codex. Heptabase also includes conversational AI assistance and an AI Tutor feature. The AI Tutor plans structured, multi-part course syllabi and facilitates step-by-step interactive lessons directly within the app. The software runs across desktop and mobile operating systems with full offline access, real-time collaboration, and local indexing capable of searching over 10,000 notes in under a second. **What makes it different:** Unifies spatial whiteboard mapping with atomic card notes, source-level PDF/video annotations, and an AI Tutor that designs structured learning curricula. **Best for:** students and researchers who need spatial whiteboards to synthesize complex PDFs, notes, and academic sources **Not ideal for:** teams looking for basic task tracking or users who require a permanent free note-taking plan ## Key features - **Visual Whiteboards and Cards** — Infinite canvas allowing users to organize concepts visually into cards, boards, and bi-directionally linked topics. - **Heptabase AI Tutor** — AI agent that generates customized syllabi, breaks complex topics into sequential lessons, and conducts interactive learning dialogues. - **PDF and Media Annotation** — Direct annotation and OCR parsing for PDF documents alongside YouTube transcript imports and note extraction. - **Offline Access and Instant Search** — Full offline availability for notes and files, paired with a search engine that queries over 10,000 notes in less than a second. - **Heptabase CLI and Developer Agents** — Command-line interface designed to work with external AI coding agents such as Claude Code and Codex. - **Research Integrations** — Sync capabilities with external knowledge sources including Readwise, Zotero, and a browser web clipper. ## Use cases - **Self-Directed Learning** — Map out complex academic subjects using the AI Tutor to generate syllabi, create guided lessons, and track topic mastery. - **Academic and Qualitative Research** — Highlight PDFs, extract transcripts, and cluster research cards on spatial canvases to spot conceptual connections. - **Daily Journaling and Note Capture** — Record thoughts, voice notes, and journal entries across desktop or mobile with automatic bi-directional card linking. ## Pros - Combines visual spatial canvases with structured card-based and block-based text editing - Native support for PDF OCR parsing, highlighting, and YouTube transcripts - Full offline access with fast local search across thousands of notes - AI Tutor automatically structures curricula and guides learners through topics - Cross-platform support on Mac, Windows, Linux, iOS, and Android ## Limitations - No permanent free plan available after the 7-day trial period - Access to GPT, Claude models, and the AI Tutor requires upgrading to the Premium tier ## Pricing | Plan | Price | Notes | | --- | --- | --- | | Pro | $8.99 / month (billed annually, save 25%) | | | Premium | $17.99 / month (billed annually, save 25%) | | | Premium+ | $53.99 / month (billed annually, save 25%) | | At the review date in September 2026, Heptabase offers three plans billed annually (with a 25% discount): Pro at $8.99/month, Premium at $17.99/month, and Premium+ at $53.99/month.
