## 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

## mindlib

mindlib is a personal knowledge management tool built around a graph rather than a flat pile of notes. You store information — text, ideas, references, clipped web content — and then connect entries in parent-child relations so a real knowledge network grows over time. Mind maps give that network a visual surface, which makes it easier to see how a project, a topic or a research thread fits together.

The product leans on AI in two ways: an assistant that can chat about your library, and mind-mapping support that helps structure what you have captured. A universal search bar sits at the centre of the workflow, so you can both file and retrieve information from the same place, and a share target lets you capture ideas from other apps.

Deployment is deliberately cross-platform. There is a web application at app.mindlib.de and dedicated Android and iOS apps, with sign-in syncing your library between them. The free tier covers small libraries of up to about 100 items, while a monthly or yearly subscription unlocks unlimited storage; importantly, data you have already created remains available and synchronised even if a subscription lapses.

**Pricing & Plans:** Freemium. The free version supports up to roughly 100 pieces of information. A monthly or yearly subscription unlocks unlimited knowledge storage, and existing data stays available and synchronised across devices after a subscription ends. Exact prices vary by plan and are shown in-app or on the store listings.

- **Graph-based knowledge network:** Save notes, ideas and web clips into a single library, then connect them in parent-child relations to grow a structured knowledge network.
- **AI mind mapping:** Turn collected entries into mind maps so you can see how topics, projects and references relate at a glance.
- **AI assistant and chat:** Ask the built-in AI assistant questions about your own library, or capture and find information conversationally.
- **Fast capture and universal search:** Use the all-in-one search bar and share target to capture ideas the moment they appear, without hunting for the right folder.
- **Web and mobile apps:** Work in the web app at app.mindlib.de or the Android and iOS apps, with your library synchronised across every device.

**Strengths:** Graph and mind-map structure that suits research and long-term projects; AI assistant and chat over your own private library; Cross-platform: web app plus Android and iOS apps with sync; Data remains accessible even after a subscription ends

**Limitations:** The marketing root domain currently returns a server error, so the web app link is the reliable entry point; The free tier caps stored items at around 100, which power users will hit quickly; Heavier than a plain notes app: mind maps and parent-child links take deliberate effort; No public API or rich third-party integration ecosystem advertised
